Introduction to Eight Disciplines of Problem Solving (8D)

The Eight Disciplines of Problem Solving (8D) is a problem solving methodology designed to find the root cause of a problem, devise a short-term fix and implement a long-term solution to prevent recurring problems. When it’s clear that your product is defective or isn’t satisfying your customers, an 8D is an excellent first step to improving Quality and Reliability.

Ford Motor Company developed this problem solving methodology, then known as Team Oriented Problem Solving (TOPS), in the 1980s. The early usage of 8D proved so effective that it was adopted by Ford as the primary method of documenting problem solving efforts, and the company continues to use 8D today.

8D has become very popular among manufacturers because it is effective and reasonably easy to teach. Below you’ll find the benefits of an 8D, when it is appropriate to perform and how it is performed.

What is Eight Disciplines of Problem Solving (8D)

The 8D problem solving process is a detailed, team oriented approach to solving critical problems in the production process. The goals of this method are to find the root cause of a problem, develop containment actions to protect customers and take corrective action to prevent similar problems in the future.

The strength of the 8D process lies in its structure, discipline and methodology. 8D uses a composite methodology, utilizing best practices from various existing approaches. It is a problem solving method that drives systemic change, improving an entire process in order to avoid not only the problem at hand but also other issues that may stem from a systemic failure.

8D has grown to be one of the most popular problem solving methodologies used for Manufacturing, Assembly and Services around the globe. Read on to learn about the reasons why the Eight Disciplines of Problem Solving may be a good fit for your company.

Why Apply Eight Disciplines of Problem Solving (8D)

The 8D methodology is so popular in part because it offers your engineering team a consistent, easy-to-learn and thorough approach to solving whatever problems might arise at various stages in your production process. When properly applied, you can expect the following benefits:

• Improved team oriented problem solving skills rather than reliance on the individual
• Increased familiarity with a structure for problem solving
• Creation and expansion of a database of past failures and lessons learned to prevent problems in the future
• Better understanding of how to use basic statistical tools required for problem solving
• Improved effectiveness and efficiency at problem solving
• A practical understanding of Root Cause Analysis (RCA)
• Problem solving effort may be adopted into the processes and methods of the organization
• Improved skills for implementing corrective action
• Better ability to identify necessary systemic changes and subsequent inputs for change
• More candid and open communication in problem solving discussion, increasing effectiveness
• An improvement in management’s understanding of problems and problem resolution

8D was created to represent the best practices in problem solving. When performed correctly, this methodology not only improves the Quality and Reliability of your products but also prepares your engineering team for future problems.

When to Apply Eight Disciplines of Problem Solving (8D)

The 8D problem solving process is typically required when:

• Safety or Regulatory issues has been discovered
• Customer complaints are received
• Warranty Concerns have indicated greater-than-expected failure rates
• Internal rejects, waste, scrap, poor performance or test failures are present at unacceptable levels

How to Apply Eight Disciplines of Problem Solving (8D)

The 8D process alternates inductive and deductive problem solving tools to relentlessly move forward toward a solution. The Quality-One approach uses a core team of three individuals for inductive activities with data driven tools and then a larger Subject Matter Expert (SME) group for the deductive activities through brainstorming, data-gathering and experimentation.

D0: Prepare and Plan for the 8D

Proper planning will always translate to a better start. Thus, before 8D analysis begins, it is always a good idea to ask an expert first for their impressions. After receiving feedback, the following criterion should be applied prior to forming a team:

Collect information on the symptoms

Use a Symptoms Checklist to ask the correct questions

Identify the need for an Emergency Response Action (ERA), which protects the customer from further exposure to the undesired symptoms

D1: Form a Team

A Cross Functional Team (CFT) is made up of members from many disciplines. Quality-One takes this principle one step further by having two levels of CFT:

• The Core Team Structure should involve three people on the respective subjects: product, process and data
• Additional Subject Matter Experts are brought in at various times to assist with brainstorming, data collection and analysis

Teams require proper preparation. Setting the ground rules is paramount. Implementation of disciplines like checklists, forms and techniques will ensure steady progress.  8D must always have two key members: a Leader and a Champion / Sponsor:

• The Leader is the person who knows the 8D process and can lead the team through it (although not always the most knowledgeable about the problem being studied)
• The Champion or Sponsor is the one person who can affect change by agreeing with the findings and can provide final approval on such changes

D2: Describe the Problem

The 8D method’s initial focus is to properly describe the problem utilizing the known data and placing it into specific categories for future comparisons. The “Is” data supports the facts whereas the “Is Not” data does not. As the “Is Not” data is collected, many possible reasons for failure are able to be eliminated. This approach utilizes the following tools:

• Problem Statement
• Affinity Diagram (Deductive tool)
• Fishbone/Ishikawa Diagram (Deductive tool)
• Problem Description

D3: Interim Containment Action

In the interim, before the permanent corrective action has been determined, an action to protect the customer can be taken. The Interim Containment Action (ICA) is temporary and is typically removed after the Permanent Correct Action (PCA) is taken.

• Verification of effectiveness of the ICA is always recommended to prevent any additional customer dissatisfaction calls

D4: Root Cause Analysis (RCA) and Escape Point

The root cause must be identified to take permanent action to eliminate it. The root cause definition requires that it can be turned on or off, at will. Activities in D4 include:

• Comparative Analysis listing differences and changes between “Is” and “Is Not”
• Development of Root Cause Theories based on remaining items
• Verification of the Root Cause through data collection
• Review Process Flow Diagram for location of the root cause
• Determine Escape Point, which is the closest point in the process where the root cause could have been found but was not

D5: Permanent Corrective Action (PCA)

The PCA is directed toward the root cause and removes / changes the conditions of the product or process that was responsible for the problem. Activities in D5 include:

• Establish the Acceptance Criteria which include Mandatory Requirements and Wants
• Perform a Risk Assessment /  Failure Mode and Effects Analysis (FMEA) on the PCA choices
• Based on risk assessment, make a balanced choice for PCA
• Select control-point improvement for the Escape Point
• Verification of Effectiveness for both the PCA and the Escape Point are required

D6: Implement and Validate the Permanent Corrective Action

To successfully implement a permanent change, proper planning is essential. A project plan should encompass: communication, steps to complete, measurement of success and lessons learned. Activities in D6 include:

• Develop Project Plan for Implementation
• Communicate the plan to all stakeholders
• Validation of improvements using measurement

D7: Prevent Recurrence

D7 affords the opportunity to preserve and share the knowledge, preventing problems on similar products, processes, locations or families. Updating documents and procedures / work instructions are expected at this step to improve future use. Activities in D7 include:

• Review Similar Products and Processes for problem prevention
• Develop / Update Procedures and Work Instructions for Systems Prevention
• Capture Standard Work / Practice and reuse
• Assure FMEA updates have been completed
• Assure Control Plans have been updated

D8: Closure and Team Celebration

Teams require feedback to allow for satisfactory closure. Recognizing both team and individual efforts and allowing the team to see the previous and new state solidifies the value of the 8D process. Activities in D8 include:

• Archive the 8D Documents for future reference
• Document Lessons Learned on how to make problem solving better
• Before and After Comparison of issue
• Celebrate Successful Completion

8D and Root Cause Analysis (RCA)

The 8D process has Root Cause Analysis (RCA) imbedded within it. All problem solving techniques include RCA within their structure. The steps and techniques within 8D which correspond to Root Cause Analysis are as follows:

• Problem Symptom is quantified and converted to “Object and Defect”
• Problem Symptom is converted to Problem Statement using Repeated Whys
• Possible and Potential Causes are collected using deductive tools (i.e. Fishbone or Affinity Diagram)
• Problem Statement is converted into Problem Description using Is / Is Not
• Problem Description reduces the number of items on the deductive tool (from step 3)
• Comparative Analysis between the Is and Is Not items (note changes and time)
• Root Cause theories are developed from remaining possible causes on deductive tool and coupled with changes from Is / Is Not
• Compare theories with current data and develop experiments for Root Cause Verification
• Test and confirm the Root Causes

Example: Multiple Why Technique

The Multiple / Repeated Why (Similar to 5 Why) is an inductive tool, which means facts are required to proceed to a more detailed level. The steps required to determine problem statement are:

• Problem Symptom is defined as an Object and Defect i.e. “Passenger Injury”
• Why? In every case “SUV’s Roll Over”
• Why? In every case, it was preceded by a “Blown Tire”
• Why? Many explanations may be applied, therefore the team cannot continue with another repeated why past “Blown Tire”
• Therefore, the Problem Statement is “Blown Tire”
• Why? Low (Air) Pressure, Tire Defect (Degradation of an Interface) and High (Ambient) Temperature
• Counter measures assigned to low pressure and tire defect

This example uses only 4 of the 5 Whys to determine the root causes without going further into the systemic reasons that supported the failure. The Repeated Why is one way to depict this failure chain. Fault Tree Analysis (FTA) could also be used.

8D Problem Solving Process

Solving major problems in a disciplined way.

By the Mind Tools Content Team

(Also known as Global 8D Problem Solving)

When your company runs into a major problem, you need to address it quickly. However, you also need to deal with it thoroughly and ensure that it doesn't recur – and this can take a lot of effort and elapsed time.

The 8D Problem Solving Process helps you do both of these seemingly-contradictory things, in a professional and controlled way. In this article, we'll look at the 8D Problem Solving Process, and we'll discuss how you can use it to help your team solve major problems.

Origins of the Tool

The Ford Motor Company® developed the 8D (8 Disciplines) Problem Solving Process, and published it in their 1987 manual, "Team Oriented Problem Solving (TOPS)." In the mid-90s, Ford added an additional discipline, D0: Plan. The process is now Ford's global standard, and is called Global 8D.

Ford created the 8D Process to help teams deal with quality control and safety issues; develop customized, permanent solutions to problems; and prevent problems from recurring. Although the 8D Process was initially applied in the manufacturing, engineering, and aerospace industries, it's useful and relevant in any industry.

The eight disciplines are shown in figure 1, below:

Figure 1: The 8D Problem Solving Process

The 8D Process works best in teams tasked with solving a complex problem with identifiable symptoms. However, you can also use this process on an individual level, as well.

Applying the Tool

To use the 8D Process, address each of the disciplines listed below, in order. Take care not to skip steps, even when time is limited; the process is only effective when you follow every step.

Discipline 0: Plan

Before you begin to assemble a team to address the problem, you need to plan your approach. This means thinking about who will be on the team, what your time frame is, and what resources you'll need to address the problem at hand.

Discipline 1: Build the Team

You should aim to put together a team that has the skills needed to solve the problem, and that has the time and energy to commit to the problem solving process.

Keep in mind that a diverse team is more likely to find a creative solution than a team of people with the same outlook (although if outlooks are too diverse, people can spend so much time disagreeing that nothing gets done).

Create a team charter that outlines the team's goal and identifies each person's role. Then, do what you can to build trust and get everyone involved in the process that's about to happen.

If your team is made up of professionals who haven't worked together before, consider beginning with team-building activities to ensure that everyone is comfortable working with one another.

Discipline 2: Describe the Problem

Once your team has settled in, describe the problem in detail. Specify the who, what, when, where, why, how, and how many; and use techniques like CATWOE and the Problem-Definition Process to ensure that you're focusing on the right problem.

Start by doing a Risk Analysis – if the problem is causing serious risks, for example, to people's health or life, then you need to take appropriate action. (This may include stopping people using a product or process until the problem is resolved.)

If the problem is with a process, use a Flow Chart , Swim Lane Diagram , or Storyboard to map each step out; these tools will help your team members understand how the process works, and, later on, think about how they can best fix it.

Discovering the root cause of the problem comes later in the process, so don't spend time on this here. Right now, your goal is to look at what's going wrong and to make sure that your team understands the full extent of the problem.

Discipline 3: Implement a Temporary Fix

Once your team understands the problem, come up with a temporary fix. This is particularly important if the problem is affecting customers, reducing product quality, or slowing down work processes.

Harness the knowledge of everyone on the team. To ensure that each person's ideas are heard, consider using brainstorming techniques such as Round Robin Brainstorming or Crawford's Slip Writing Method , alongside more traditional team problem solving discussions.

Once the group has identified possible temporary fixes, address issues such as cost, implementation time, and relevancy. The short-term solution should be quick, easy to implement, and worth the effort.

Discipline 4: Identify and Eliminate the Root Cause

Once your temporary fix is in place, it's time to discover the root cause of the problem.

Conduct a Cause and Effect Analysis to identify the likely causes of the problem. This tool is useful because it helps you uncover many possible causes, and it can highlight other problems that you might not have been aware of. Next, apply Root Cause Analysis to find the root causes of the problems you've identified.

Once you identify the source of the problem, develop several permanent solutions to it.

If your team members are having trouble coming up with viable permanent solutions, use the Straw Man Concept to generate prototype solutions that you can then discuss, tear apart, and rebuild into stronger solutions.

Discipline 5: Verify the Solution

Once your team agrees on a permanent solution, make sure that you test it thoroughly before you fully implement it, in the next step.

• Conducting a Failure Mode and Effects Analysis (FMEA) to spot any potential problems.
• Using Impact Analysis to make sure that there will be no unexpected future consequences.
• Using Six Thinking Hats to examine the fix from several different emotional perspectives.

Last, conduct a Blind Spot Analysis to confirm that you and your team haven't overlooked a key factor, or made an incorrect assumption about this solution.

Discipline 6: Implement a Permanent Solution

Once your team reaches a consensus on the solution, roll your fix out. Monitor this new solution closely for an appropriate period of time to make sure that it's working correctly, and ensure that there are no unexpected side effects.

Discipline 7: Prevent the Problem From Recurring

When you're sure that the permanent solution has solved the problem, gather your team together again to identify how you'll prevent the problem from recurring in the future.

You might need to update your organization's standards, policies, procedures, or training manual to reflect the new fix. You'll likely also need to train others on the new process or standard. Finally, you'll need to consider whether to change your management practices or procedures to prevent a recurrence.

Discipline 8: Celebrate Team Success

The last step in the process is to celebrate and reward your team's success . Say "thank you" to everyone involved, and be specific about how each person's hard work has made a difference. If appropriate, plan a party or celebration to communicate your appreciation.

Before the team disbands, conduct a Post-Implementation Review to analyze whether your solution is working as you thought, and to improve the way that you solve problems in the future.

In the late 1980s, Ford Motor Company developed the 8D (8 Disciplines) Problem Solving Process to help manufacturing and engineering teams diagnose, treat, and eliminate quality problems. However, teams in any industry can use this problem solving process.

The eight disciplines are:

• Build the Team.
• Describe the Problem.
• Implement a Temporary Fix.
• Identify and Eliminate the Root Cause.
• Verify the Solution.
• Implement a Permanent Solution.
• Prevent the Problem From Recurring.
• Celebrate Team Success.

The 8D Problem Solving Process is best used with a team solving complex problems; however, individuals can also use it to solve problems on their own.

8D Problem Solving: Comprehensive Breakdown and Practical Applications

The 8D problem-solving process stands as a beacon of structured analysis and corrective action within the complexities of operational pitfalls and quality control discrepancies across industries. Originating from the automotive industry and since adopted widely, the methodology offers a meticulous step-by-step approach that fosters team cohesion, addresses problems at their roots, and implements sustainable solutions.

This article seeks to delve into the nuances of the 8D problem-solving framework, presenting a lucid exposition of its origins, a detailed foray into each step enriched by practical examples, and concluding with the unequivocal benefit bouquet it presents to the organization adopting it.

The Origins of the 8D Problem Solving Methodology

The 8D, or "Eight Disciplines," problem-solving approach germinated from the fertile grounds of collaborative efforts to ensure superior quality and reliability in manufacturing. Initially developed by the Ford Motor Company in the 1980s, this systematic method was a response to a confluence of quality and operational issues that were pervasive in the automotive industry. It drew broader appeal as its efficacy became apparent - functioning as an amalgam of logic, analytics, and teamwork to tackle problems methodically.

The wide reach of the 8D methodology is evident in industries ranging from manufacturing to healthcare, aerospace to IT, and beyond. Its universal applicability stems from a foundational adherence to principle over process, transcending the intricacies of industry-specific challenges. By combining reactive and proactive measures, the 8D method helps in not just extinguishing the fire, but also preventing its outbreak, making it an enduring asset in the organizational toolkit.

The 8 Steps of Problem Solving

An incursion into the 8D methodology reveals a framework that is both systematic and flexible. Each step is sequenced to ensure that issues are not merely patched but genuinely resolved, implementing robust preventive measures to curtail recurrences. This section expounds on each disciplinary step and serves as a substrate for practical implementation examples, supplementing theoretical insights with real-world applicability.

Step 1: Establish a Team

The cornerstone of any formidable 8D approach begins with assembling a competent team. The wisdom embedded in this initial phase is the recognition that effective problem-solving is not a solitary venture but a collaborative pursuit. A multidisciplinary team brings diverse perspectives that are critical in diagnosing issues accurately and devising solutions effectively.

When determining team composition, the emphasis should be on a mix of skills and expertise relevant to the problem at hand. Roles within the team should be clearly defined to streamline activities and foster accountability. Each member should be well-versed in their responsibilities, from those leading the problem-solving charge to those executing and tracking actions.

Step 2: Describe the Problem

Clarity is vital in the second step, which necessitates delineating the problem with precision. A meticulous description sets the foundation for targeted analysis and actionable solutions. It involves accruing information that is factual, quantifiable, and devoid of assumptions – the cornerstone of an accurate problem portrayal.

Techniques like '5W2H' (who, what, when, where, why, how, how much) can galvanize teams into crafting detailed problem descriptions. An exemplar of a well-articulated problem statement might state, "Machine X has experienced a 15% decline in output quality, resulting in a monthly loss of 200 units of product Y since January due to recurrent mechanical inaccuracies."

Step 3: Develop Interim Containment Actions

Addressing a problem's immediate impact is pivotal to prevent exacerbation as a root cause analysis is conducted. Interim containment actions can be likened to first aid – essential, though not the definitive cure. These measures should be rigorously designed to quell the problem's spread or intensification without creating new issues.

An interim action for the aforementioned issue with Machine X could involve adjusting the production schedule to mitigate output loss while the machine is under examination. This demonstrates a temperate solution, buying time for a comprehensive fix without severely disrupting the production chain.

Step 4: Define and Verify the Root Cause(s)

Singular in its focus yet pluralistic in its approach, this phase is committed to uncovering the underlying reasons for the problem. Root cause identification is a task of surgical precision, necessitating a deep dive into the problem without the constraints of predetermined notions.

Techniques such as the "5 Whys" and "Fishbone Diagram" guide problem solvers through a structured investigation of potential causes. Verification is as crucial as identification, ensuring that purported root causes stand up to scrutiny and testing.

Step 5: Verify Permanent Corrective Action(s)

Once root causes have been established, attention shifts to devising and validating long-term corrective actions. This step traverses the path from theory to practice. It requires a judicious appraisal of potential solutions with a clear-eyed view of their feasibility, effectiveness, and sustainability.

Best practices in this step incorporate piloting solutions on a smaller scale, enabling refinement before full-scale implementation. A well-considered corrective action for Machine X might involve upgrading mechanical components identified as failure points, subject to cost-benefit analysis and potential disruption to the production line.

Step 6: Implementing and Validating Permanent Corrective Actions

This step transitions the plan into reality, pushing the corrective actions beyond the threshold into the operational environment. Careful implementation is the linchpin, with detailed plans and schedules ensuring that actions are well-executed and efficacious.

The validation process is a keystone in affirming that corrective actions deliver the intended improvements. For Machine X, this could entail monitoring post-repair performance metrics over a defined period against pre-issue levels to authenticate the efficacy of the improvements.

Step 7: Preventive Measures

Armed with insights gleaned, the 7th step propels the methodology into preventative mode. Here, the onus is on forestalling a problem’s resurgence by ingraining the lessons learned into the organizational fabric. The aim is to encapsulate these insights in policies, procedures, or system changes.

This could mean revising maintenance schedules or worker training programs for Machine X to include the specific nuances that led to the mechanical inaccuracies, thereby shielding against repeat episodes.

Step 8: Congratulate Your Team

The final step encompasses a human-centered focus on recognition and commendation. Acknowledgment of the team’s efforts reinforces motivation, fosters a positive culture, and encourages engagement in future problem-solving initiatives.

Celebrating the success could manifest in a ceremonious recognition of the team’s achievements, an internal announcement of their contributions, or a tangible expression of appreciation. This not only cements the accomplishment but also propels a sense of camaraderie and collective purpose.

The Importance of the 8D Problem Solving Process

A mature consideration of the 8D problem-solving process corroborates its contributory significance in unraveling complex issues and instituting consequential improvements. The benefits it confers are manifest in enhanced product quality, heightened customer satisfaction, and the stimulation of a proactive problem-solving culture. Challenges do persist, mainly in the form of resistance to change or insufficient training; nevertheless, with a conscientious implementation, these can be navigated.

Moreover, the 8D approach aligns seamlessly with the pursuit of continuous improvement – a cornerstone of many business philosophies such as Lean and Six Sigma. It thus serves not only as a solution framework but also as a catalyst for organizational growth and learning.

In summary, the 8D problem-solving methodology stands out for its disciplined, team-driven, and methodical approach to tackling complex problems. From its historical roots in the automotive industry to its implementation in modern enterprises, its efficacy in achieving sustainable solutions is undoubted. Online certificate programs and problem-solving courses often feature 8D due to its relevance and value across industries.

As this article delineates each step, with practical applications and advice, the message is clear: mastery of 8D is not just for immediate problem resolution – it is a pathway to building a resilient and adaptive organization capable of facing the challenges of an ever-changing business landscape.

What are the key steps involved in the 8D Problem Solving process and how do they interact with each other?

Introduction to the 8d process.

The 8D Problem Solving process stands tall. It is a structured approach. Businesses use it widely. 8D tackles complex problems effectively. It drives teams towards lasting solutions. It also fosters quality and reliability. The "D" denotes eight disciplined steps. These steps guide teams. They identify, correct, and prevent issues.

8D Steps Explained

D1: establish the team.

Form a skilled team first. Diversity matters here. Each member brings insights. Their combined expertise is crucial. Team formation kicks off the process.

D2: Describe the Problem

Articulate the issue clearly. Use quantifiable data here. Understanding the scope matters. Have accurate problem statements ready. They pave the way forward.

D3: Develop Interim Containment Action

Ensure a temporary fix. It limits the problem's impact. Speed is of the essence. However, ensure the action is effective. The goal is to stabilize the situation.

D4: Determine Root Cause

Dig deep into causes. Use data-driven analysis. Techniques include fishbone diagrams. Five Whys is also popular. Root cause analysis is pivotal. It prepares the team for corrective actions.

D5: Design and Verify Permanent Corrective Actions

Choose the best corrective action. Rigorous selection criteria apply. Effectiveness and efficiency matter. Verify through testing. Make certain the solution fits.

D6: Implement and Validate Permanent Corrective Actions

Roll out the solution. Watch closely for results. Validation takes place here. Use performance indicators for this. They must indicate that the solution works.

D7: Prevent Recurrence

Embed the improvement. Update systems and policies. Training may be necessary. Maintain the gains. This step safeguards the future. Documentation is important here.

D8: Congratulate the Team

Never overlook recognition. Acknowledge everyone's efforts. Celebrate the success achieved. It boosts team morale. It also promotes a culture of quality.

Interplay Between Steps

The interdependence is strong. Each step builds on the previous one. For example, a strong team in D1 enhances problem understanding in D2. Similarly, effective interim actions in D3 set the stage for a thorough root cause analysis in D4.

The verification in D5 ensures the solution from D4 is sound. Implementation in D6 then relies on the verified action. To prevent recurrence (D7), one must understand the root cause. The entire process relies on clear communication. Team recognition (D8) closes the loop neatly. It paves the way for future problem-solving success.

In essence, the 8D steps are interlinked. Each step informs the next. Teams achieve the best results by following the sequence. They also adapt as needed. 8D enforces a discipline that leads to high-quality results. The interaction between steps ensures problems do not just disappear. They stay solved. This is the power of an integrated problem-solving approach.

Can you provide some practical examples of the effective application of 8D Problem Solving strategies in real-life settings?

The Eight Disciplines (8D) Process

At the heart of the 8D corrective action methodology lies a structured, step-by-step approach that guides organizations through eight distinct disciplines. 

Each discipline builds upon the previous one, ensuring a thorough investigation, analysis, and resolution of the problem at hand.

The eight disciplines of the 8D process are designed to facilitate a systematic and disciplined approach to problem-solving, leveraging cross-functional collaboration, analytical tools, and data-driven decision-making. 

D0: Planning and Preparation

Before embarking on the 8D corrective action journey, proper planning and preparation are crucial. This initial step, often referred to as Discipline Zero (D0), lays the foundation for a successful problem-solving effort.

During D0, the team gathers relevant information about the problem, assesses the need for interim containment actions, and establishes the prerequisites for forming an effective cross-functional team. 

This stage involves collecting data on symptoms, identifying potential risks, and ensuring that the necessary resources and support are in place to execute the 8D process effectively.

D1: Team Formation

The first formal discipline of the 8D process focuses on assembling a cross-functional team with the collective knowledge, skills, and expertise required to tackle the problem at hand. 

Effective team formation is critical to the success of the 8D corrective action effort, as it ensures diverse perspectives and a comprehensive understanding of the issue.

During D1, team members are carefully selected from various departments or functions, such as product engineering, process engineering, quality assurance, and data analysis.

Best practices in team formation involve considering factors such as technical expertise, problem-solving skills, interpersonal abilities, and the availability and commitment of potential team members. 

Establishing ground rules, communication protocols, and team-building exercises can further enhance collaboration and effective teamwork.

D2: Problem Description

In Discipline 2, the team focuses on accurately describing the problem, utilizing quantitative data and evidence-based approaches. 

This step is crucial, as it establishes a shared understanding of the issue and guides the subsequent steps of the 8D process.

The problem description involves defining the problem statement in specific, measurable terms, identifying the affected product or process, and quantifying the impact on operations, quality, customer satisfaction, and costs. 

Tools such as the “ 5 Whys ” technique, Ishikawa (fishbone) diagrams , and “ Is/Is Not ” analysis can aid in this process, helping to capture relevant details and categorize information.

D3: Interim Containment Actions

While the team works towards identifying and implementing permanent solutions, Discipline 3 focuses on implementing interim containment actions to mitigate the immediate impact of the problem and protect customers from further exposure.

Interim containment actions are temporary measures designed to isolate the problem and prevent it from causing further harm or spreading to other areas, processes, or products. 

These actions may include segregating defective products, implementing additional inspections or checks, or introducing manual oversight until permanent corrective actions are in place.

It is essential to verify the effectiveness of interim containment actions and monitor their implementation to ensure that they are successful in containing the problem and minimizing its impact on operations and customers.

D4: Root Cause Analysis

At the core of the 8D corrective action process lies Discipline 4, which focuses on identifying the root causes of the problem through rigorous analysis and data-driven investigation. 

This step is crucial, as it lays the foundation for developing effective and sustainable corrective actions.

During root cause analysis, the team employs various analytical tools and techniques, such as comparative analysis , fault tree analysis , and root cause verification experiments. 

These methods help to isolate and verify the underlying causes of the problem, separating symptoms from true root causes.

Thorough documentation and verification of root causes are essential in this discipline, ensuring that the team has a solid foundation for developing effective corrective actions.

D5: Permanent Corrective Actions (PCAs)

Building upon the insights gained from root cause analysis , Discipline 5 focuses on selecting and verifying permanent corrective actions (PCAs) that address the identified root causes and mitigate the risk of future occurrences.

During this stage, the team evaluates potential corrective actions based on their effectiveness in addressing the root causes, as well as their feasibility, cost, and potential impact on other processes or systems. 

Risk assessment tools, such as Failure Mode and Effects Analysis (FMEA), can aid in this evaluation process.

Once the most appropriate corrective actions have been selected, the team verifies their effectiveness through pilot testing , simulations, or other validation methods. 

This step ensures that the proposed solutions will indeed resolve the problem and prevent its recurrence without introducing unintended consequences.

Detailed planning and documentation of the corrective actions, including acceptance criteria, implementation timelines, and responsibilities, are critical components of Discipline 5.

D6: Implementation and Validation

In Discipline 6, the team focuses on implementing the selected permanent corrective actions and validating their effectiveness in resolving the problem and preventing future occurrences.

This stage involves developing a comprehensive project plan that outlines the steps, timelines, and resources required for successful implementation. 

Effective communication and coordination with all relevant stakeholders, including cross-functional teams and management, are essential to ensure a smooth transition and minimize disruptions.

During implementation, the team closely monitors the progress and performance of the corrective actions, gathering data and feedback to validate their effectiveness. 

This validation process may involve conducting simulations, inspections, or collecting performance metrics to assess the impact of the implemented solutions.

If the validation process reveals any shortcomings or unintended consequences, the team may need to revisit the corrective actions, make adjustments, or conduct further root cause analysis to address any remaining issues.

D7: Preventive Actions

Discipline 7 of the 8D process focuses on taking preventive measures to ensure that the lessons learned and improvements made during the problem-solving journey are embedded into the organization’s processes, systems, and culture.

In this stage, the team reviews similar products, processes, or areas that could be affected by the same or similar root causes, identifying opportunities to apply preventive actions more broadly. 

This proactive approach helps to mitigate the risk of future occurrences and promotes a culture of continuous improvement .

Effective implementation of preventive actions requires cross-functional collaboration, clear communication, and ongoing monitoring to ensure their sustained effectiveness.

D8: Closure and Celebration

The final discipline of the 8D process, D8, serves as a critical step in recognizing the team’s efforts, sharing lessons learned, and celebrating the successful resolution of the problem.

During this stage, the team conducts a final review of the problem-solving journey, documenting key lessons and insights that can be applied to future projects. 

This documentation not only preserves institutional knowledge but also facilitates continuous improvement by enabling the organization to build upon past experiences.

Equally important is the recognition and celebration of the team’s achievements. By acknowledging the collective efforts, dedication, and collaboration of team members, organizations can foster a positive and supportive culture that values problem-solving and continuous improvement.

Formal recognition events, such as team presentations or awards ceremonies, can be organized to showcase the team’s accomplishments and highlight the impact of their work on the organization’s quality, customer satisfaction, and overall performance.

By completing the eight disciplines of the 8D process, organizations can effectively navigate complex problems, identify root causes, implement sustainable solutions, and establish a foundation for continuous improvement and organizational learning.

Integrating 8D Corrective Action with Quality Management Systems

While the 8D problem-solving methodology offers a robust framework for addressing quality issues and driving continuous improvement, its effectiveness can be further amplified by integrating it with an organization’s quality management systems . 

Leveraging enterprise-level software solutions can streamline the 8D process, enhance collaboration, and foster a culture of continuous improvement.

What is 8D? A template for efficient problem-solving

How you respond when problems arise is one of the most defining qualities of a manager. Luckily, there are tools you can use to master problem-solving. The 8D method of problem-solving combines teamwork and basic statistics to help you reach a logical solution and prevent new issues from arising.

You’ve spent months overseeing the development of your company's newest project. From initiation, planning, and execution, you’re confident this may be your best work yet.

Until the feedback starts rolling in.

There’s no sugar-coating it—things don’t always go as planned. But production or process issues are hardly a signal to throw in the towel. Instead, focus on honing your problem-solving skills to find a solution that keeps it from happening again. 

The 8D method of problem solving emphasizes the importance of teamwork to not only solve your process woes but prevent new ones from occurring. In this guide, we’ll break down what 8D is, how to use this methodology, and the benefits it can give to you and your team. Plus, get an 8D template to make solving your issue easier. 

What is 8D?

The eight disciplines (8D) method is a problem-solving approach that identifies, corrects, and eliminates recurring problems. By determining the root causes of a problem, managers can use this method to establish a permanent corrective action and prevent recurring issues. 

How do you use the 8D method?

The 8D method is a proven strategy for avoiding long-term damage from recurring problems. If you’re noticing issues in your workflow or processes, then it’s a good time to give this problem-solving method a try. 

To complete an 8D analysis, follow “the eight disciplines” to construct a statistical analysis of the problem and determine the best solution.

The eight disciplines of problem-solving

8D stands for the eight disciplines you will use to establish an 8D report. As you may notice, this outline starts with zero, which makes nine total disciplines. The “zero stage” was developed later as an initial planning stage. 

To illustrate these steps, imagine your organization experienced a decline in team innovation and productivity this past year. Your stakeholders have noticed and want to see changes implemented within the next six months. Below, we’ll use the 8D process to uncover a morale-boosting solution.

D0: Prepare and plan

Before starting the problem-solving process, evaluate the problem you want to solve. Understanding the background of the problem will help you identify the root cause in later steps. 

Collect information about how the problem has affected a process or product and what the most severe consequences may be. Planning can include:

Gathering data

Determining the prerequisites for solving the problem

Collecting feedback from others involved

If we look back at our example, you may want to figure out whether this decline in morale is organization-wide or only applies to a few departments. Consider interviewing a few employees from different departments and levels of management to gain some perspective. Next, determine what knowledge and skills you will need to solve this lapse in productivity. 

D1: Form your team

Create a cross-functional team made up of people who have knowledge of the various products and workflows involved. These team members should have the skills needed to solve the problem and put corrective actions in place. 

Steps in this discipline may include:

Appointing a team leader

Developing and implementing team guidelines

Determining team goals and priorities

Assigning individual roles

Arranging team-building activities

From our example, a solid team would consist of people with first-hand experience with the issues—like representatives from all departments and key people close to workshop-level work. You may also want to pull someone in from your HR department to help design and implement a solution. Most importantly, make sure the people you choose want to be involved and contribute to the solution.

D2: Identify the problem

You may have a good understanding of your problem by now, but this phase aims to break it down into clear and quantifiable terms by identifying the five W’s a and two H’s (5W2H):

Who first reported the problem?

What is the problem about?

When did it occur and how often?

Where did it occur (relating to the sector, supplier, machine, or production line involved)?

Why is solving the problem important?

How was the problem first detected?

How many parts/units/customers are affected?

Use your team’s insights to answer these questions. From our example, your team may conclude that: 

Employees feel overwhelmed with their current workload. 

There is no real structure or opportunity to share new ideas.

Managers have had no training for meetings or innovation settings.

Disgruntled employees know they can achieve more—and want to achieve more—even if they seem disengaged.

Once you answer these questions, record an official problem statement to describe the issue. If possible, include photos, videos, and diagrams to ensure all parties have a clear understanding of the problem. It may also help to create a flowchart of the process that includes various steps related to the problem description.

D3: Develop an interim containment plan

Much like we can expect speedy first aid after an accident, your team should take immediate actions to ensure you contain the problem—especially if the problem is related to customer safety. 

An interim containment plan will provide a temporary solution to isolate the problem from customers and clients while your team works to develop a permanent corrective action. This band-aid will help keep your customers informed and safe—and your reputation intact.

Because your findings revealed workers were overworked and managers lacked training, your team suggests scheduling a few mandatory training sessions for leaders of each department covering time and stress management and combating burnout . You may also want to have a presentation outlining the topics of this training to get key managers and stakeholders interested and primed for positive upcoming changes. 

D4: Verify root causes and escape points

Refer back to your findings and consult with your team about how the problem may have occurred. The root cause analysis involves mapping each potential root cause against the problem statement and its related test data. Make sure to test all potential causes—fuzzy brainstorming and sloppy analyses may cause you to overlook vital information. 

In our example, focus on the “why” portion of the 5W2H. You and your team identify six root causes:

Managers have never had any training

There is a lack of trust and psychological safety

Employees don’t understand the objectives and goals

Communication is poor

Time management is poor

Employees lack confidence

In addition to identifying the root causes, try to pinpoint where you first detected the problem in the process, and why it went unnoticed. This is called the escape point, and there may be more than one. 

D5: Choose permanent corrective actions

Work with your team to determine the most likely solution to remove the root cause of the problem and address the issues with the escape points. Quantitatively confirm that the selected permanent corrective action(s) (PCA) will resolve the problem for the customer. 

Steps to choosing a PCA may include:

Determining if you require further expertise

Ensuring the 5W2Hs are defined correctly

Carrying out a decision analysis and risk assessment

Considering alternative measures

Collecting evidence to prove the PCA will be effective

Your team decides to roll out the training used in the interim plan to all employees, with monthly company-wide workshops on improving well-being. You also plan to implement meetings, innovation sessions, and team-coaching training for managers. Lastly, you suggest adopting software to improve communication and collaboration. 

D6: Implement your corrective actions

Once all parties have agreed on a solution, the next step is to create an action plan to remove the root causes and escape points. Once the solution is in effect, you can remove your interim containment actions.

After seeing success with the training in the interim phase, your stakeholders approve all of your team’s proposed PCAs. Your representative from HR also plans to implement periodic employee wellness checks to track employee morale .

To ensure your corrective action was a success, monitor the results, customer, or employee feedback over a long period of time and take note of any negative effects. Setting up “controls” like employee wellness checks will help you validate whether your solution is working or more needs to be done. 

D7: Take preventive measures

One of the main benefits of using the 8D method is the improved ability to identify necessary systematic changes to prevent future issues from occurring. Look for ways to improve your management systems, operating methods, and procedures to not only eliminate your current problem, but stop similar problems from developing later on.

Based on our example, the training your team suggested is now adopted in the new manager onboarding curriculum. Every manager now has a “meeting system” that all meetings must be guided by, and workloads and projects are managed as a team within your new collaboration software . Innovation is improving, and morale is at an all-time high!

D8: Celebrate with your team

The 8D method of problem-solving is impossible to accomplish without dedicated team members and first-class collaboration. Once notes, lessons, research, and test data are documented and saved, congratulate your teammates on a job well done! Make an effort to recognize each individual for their contribution to uncovering a successful solution.

Check out our 8D report template below to help you record your findings as you navigate through the eight disciplines of problem solving. This is a formal report that can be used as a means of communication within companies, which makes for transparent problem-solving that you can apply to the entire production or process chain.

Benefits of using the 8D method

The 8D method is one of the most popular problem-solving strategies for good reason. Its strength lies in teamwork and fact-based analyses to create a culture of continuous improvement —making it one of the most effective tools for quality managers. The benefits of using the 8D method include: 

Improved team-oriented problem-solving skills rather than relying on an individual to provide a solution

Increased familiarity with a problem-solving structure

A better understanding of how to use basic statistical tools for problem-solving

Open and honest communication in problem-solving discussions

Prevent future problems from occurring by identifying system weaknesses and solutions

Improved effectiveness and efficiency at problem-solving

Better collaboration = better problem solving

No matter how good a manager you are, production and process issues are inevitable. It’s how you solve them that separates the good from the great. The 8D method of problem solving allows you to not only solve the problem at hand but improve team collaboration, improve processes, and prevent future issues from arising.

Mastering the 8D Problem Solving Method: A Comprehensive Guide

It is often said that “a stitch in time saves nine.” Efficient problem-solving is an essential skill , especially in a professional environment.

When it comes to addressing complex issues, the 8D Problem Solving method has gained significant traction across various industries. In this comprehensive guide, we will explore the 8D Problem Solving method, its history, and its application across multiple sectors.

History of the 8D Problem Solving Method

The 8D Problem Solving approach has its origins in World War II when the American military was under intense pressure to produce reliable weapons as quickly as feasible.

The military established a methodical approach to problem-solving, focusing on quality control and continual improvement, to ensure that resources were used effectively.

This was the first instance of what would later develop into the 8D technique.

The writings of Walter Shewhart , W. Edwards Deming , and Joseph M. Juran , who set the groundwork for contemporary quality control and continuous improvement ideas, had a substantial impact on the development of the 8D Problem Solving approach.

Problem solving is a vital skill for any business that wants to survive and thrive in today’s competitive and dynamic environment. However, not all problems are created equal. Some are simple and straightforward, while others are complex and multifaceted. How can businesses effectively tackle these challenging problems and prevent them from recurring?

One of the most powerful and proven problem-solving methodologies is 8D problem solving. 8D stands for eight disciplines, which are a series of steps that guide teams through the process of identifying, analyzing, resolving, and preventing problems. 8D problem solving can help businesses improve their quality, reduce their costs, and enhance their customer satisfaction.

What is 8D Problem Solving

8D problem solving is a structured and systematic approach to solving complex problems that require cross-functional collaboration and root cause analysis. It was developed by Ford Motor Company in the late 1980s as a way to address customer complaints and improve product quality. Since then, it has been widely adopted by many organizations across various sectors.

The core principles and objectives of 8D problem solving are:

• Focus on the customer’s needs and expectations
• Involve a multidisciplinary team with relevant expertise and authority
• Use data and facts to support decision making
• Identify and eliminate the root causes of the problem
• Implement corrective actions that prevent reoccurrence
• Document and communicate the problem-solving process and results

The 8D methodology differs from other problem-solving approaches in several ways. First, it emphasizes team-oriented problem-solving. Second, it follows a sequential and logical order of steps that ensures thoroughness and consistency. Third, it uses various tools and techniques to facilitate analysis and action. Fourth, it incorporates feedback loops and verification methods to ensure effectiveness and sustainability.

The Eight Disciples of Problem Solving

D1: establish the team.

The first step in the 8D approach is to form a team that will work on the problem. The team should consist of members who have knowledge, experience, or involvement in the problem area. The team should also have a leader who will coordinate the activities and communicate with stakeholders.

The purpose of establishing the team is to:

• Define the roles and responsibilities of each team member
• Establish the scope and boundaries of the problem
• Set the goals and expectations for the problem-solving process
• Allocate the resources and time required for the process

D2: Describe the Problem

The second step in this problem-solving method is to define and describe the problem in detail. The team should use data and facts to describe the problem as accurately as possible. The team should also use tools such as the 5W2H method (who, what, where, when, why, how, how much), Six Sigma, or an IS/IS NOT matrix to clarify the aspects of the problem.

Defining and describing the problem allows businesses to:

• Establish a common understanding of the problem among the team members
• Identify the symptoms, effects, and impacts of the problem
• Quantify the magnitude and frequency of the problem
• Specify the criteria for evaluating potential solutions

D3: Develop Interim Containment Actions

The third step in 8D problem solving is to develop interim containment actions that will prevent or minimize the negative consequences of the problem until a permanent solution is found. The team should identify and implement actions that will isolate, control, or eliminate the causes or sources of variation that contribute to the problem.

When you develop interim containment actions, you:

• Protect the customer from defective products or services
• Reduce the risk of further damage or harm
• Maintain operational continuity and stability
• Buy time for root cause analysis and corrective actions

D4: Determine Root Causes

The fourth step in the 8D method is to determine the root causes responsible for creating or allowing the problem to occur. The team should use data analysis tools such as Pareto charts, histograms, scatter plots, or fishbone diagrams to identify possible causes. The team should also use root cause analysis techniques such as 5 Whys, fault tree analysis, or Failure Modes and Effect Analysis (FMEA) to verify or validate the causes.

The purpose of determining root causes is to:

• Understand why the problem happened
• Identify all possible factors that influence or contribute to the problem
• Eliminate superficial or symptomatic causes
• Prevent jumping to conclusions or making assumptions

D5: Choose Permanent Corrective Actions

The fifth step in 8D problem solving is to choose permanent corrective actions that will address or remove root causes permanently. The team should generate multiple possible solutions using brainstorming techniques such as SCAMPER (substitute, combine, adapt, modify, put to another use, eliminate, reverse) or TRIZ (theory of inventive problem solving). The team should also evaluate each solution using criteria such as feasibility, effectiveness, cost, risk, or impact.

Choosing permanent corrective actions helps to:

• Select the best solution that meets customer needs and expectations
• Ensure that root causes are eliminated or prevented from recurring
• Consider trade-offs between different solutions
• Plan for implementation challenges or barriers

D6: implement permanent corrective actions.

The sixth step in 8D problem solving is to implement permanent corrective actions that were chosen in D5. The team should develop an action plan that specifies who will do what by when using tools such as Gantt charts or PDCA cycles (plan-do-check-act). The team should also execute the action plan according to schedule using tools such as checklists or standard operating procedures.

The purpose of implementing permanent corrective actions is to:

• Put the chosen solution into practice
• Monitor progress and performance during implementation
• Resolve any issues or problems that arise during the implementation
• Document changes or modifications made during implementation

D7: Prevent Recurrence

The seventh step in 8D problem solving is to prevent recurrence by ensuring that permanent corrective actions are effective and sustainable. The team should verify that root causes have been eliminated using tools such as control charts or statistical process control (SPC). The team should also validate that customer requirements have been met using tools such as surveys or audits.

Preventing reoccurrence helps to:

• Confirm that permanent corrective actions have solved the problem
• Evaluate customer satisfaction with products or services after implementation
• Identify opportunities for further improvement or optimization
• Standardize best practices or lessons learned from implementation

D8: Recognize Team Efforts

The eighth step in 8D problem solving is recognizing team efforts by acknowledging their contributions and achievements throughout the process. The team should celebrate their success by sharing their results with stakeholders using tools such as reports or presentations. The team should also appreciate their efforts by rewarding them with recognition or incentives.

The purpose of recognizing team efforts is to:

• Motivate team members for future challenges
• Build trust and rapport among team members
• Enhance team morale and cohesion
• Promote a culture of continuous improvement

Implementing 8D Problem-Solving Methodology

To illustrate the versatility and applicability of 8D problem solving across different industries and contexts, here is a hypothetical example of successful 8D problem solving:

Example: Reducing Customer Complaints in a Food Manufacturing Company

A food manufacturing company was facing a high rate of customer complaints due to foreign materials found in their products. The company used 8D problem solving to address this issue and improve product quality. Here are the steps they took within each discipline:

The company formed a cross-functional team consisting of representatives from quality assurance, production, engineering, and customer service. The team leader was the quality assurance manager who had the authority and responsibility to coordinate the activities and communicate with stakeholders.

The team defined and described the problem using data and facts from customer complaints and product inspection records. The team used the 5W2H method to clarify the aspects of the problem. The problem statement was: “In the past six months, we have received 25 customer complaints due to foreign materials such as metal shavings, plastic pieces, or wood chips found in our products.”

The team developed interim containment actions that would prevent or minimize the occurrence of foreign materials in their products until a permanent solution was found. The team identified and implemented measures such as increasing the frequency and intensity of product inspection, installing additional metal detectors and filters in the production line, and segregating and quarantining any products that were suspected or confirmed to contain foreign materials.

The team determined the root causes that were responsible for creating or allowing foreign materials to enter their products. They then used data analysis tools such as Pareto charts and fishbone diagrams to identify potential causes. Root cause analysis techniques such as 5 Whys to verify or validate the causes were also implemented.

Ultimately, they found that there were three main root causes:

• inadequate maintenance of equipment that resulted in metal shavings or plastic pieces falling off during operation;
• improper handling of raw materials that resulted in wood chips or other contaminants being mixed in during storage or transportation;
• lack of awareness or training of staff on how to prevent or detect foreign materials in products.

The team chose permanent corrective actions that would address or remove root causes permanently. The team generated multiple possible solutions using brainstorming techniques such as SCAMPER and TRIZ. They also evaluated each solution using criteria such as feasibility, effectiveness, cost, risk, or impact. Eventually, they selected the best solutions that met customer needs and expectations.

The solutions were:

• implementing a preventive maintenance program for equipment that included regular inspection, cleaning, and replacement of parts;
• establishing a quality control system for raw materials that included verification, testing, and labeling of incoming materials;
• conducting a training program for staff on how to prevent, detect, and report foreign materials in products.

The team implemented permanent corrective actions that were chosen in D5. An action plan that specified who would do what by when using tools such as Gantt charts and PDCA cycles was then developed. They then executed the action plan according to schedule using tools such as checklists and standard operating procedures.

The team prevented recurrence by ensuring that permanent corrective actions were effective and sustainable. They first verified that root causes had been eliminated using tools such as control charts and statistical process control (SPC). Next, they validated that customer requirements had been met using tools such as surveys and audits. After implementing permanent corrective actions, the rate of customer complaints due to foreign materials dropped by 90%.

Team efforts were recognized by acknowledging their contributions and achievements throughout the process. The team celebrated their success by sharing their results with stakeholders using tools such as reports and presentations. Management also appreciated their efforts by rewarding them with recognition or incentives such as certificates, gift cards, or bonuses.

Common Challenges and Best Practices in 8D Problem Solving

Despite its benefits and advantages,

8D problem solving can also pose some challenges for businesses that want to implement it effectively. Some of these challenges are:

• Resistance to change from staff or management who are used to existing processes or practices
• Lack of commitment or support from senior leaders who do not see the value or urgency of problem-solving
• Difficulty in defining or measuring problems
• Insufficient data or information to support analysis or decision making
• Conflicts or disagreements among team members or stakeholders due to different opinions or interests

To overcome these challenges and ensure successful 8D problem solving, businesses can adopt some best practices such as:

• Communicating the benefits and objectives of 8D problem solving to staff and management
• Securing the buy-in and sponsorship of senior leaders who can provide direction and resources
• Using clear and objective criteria to define and measure problems
• Collecting and analyzing relevant and reliable data or information
• Resolving conflicts or disagreements through constructive dialogue and compromise

To ensure that 8D problem-solving efforts are not wasted or forgotten, businesses need to measure the effectiveness and impact of their initiatives. Measuring the effectiveness of 8D problem-solving efforts can help businesses:

• Assess whether they have achieved their goals and expectations
• Evaluate whether they have improved their performance and customer satisfaction
• Identify areas for further improvement or optimization
• Demonstrate their value and credibility to stakeholders

To measure the effectiveness of 8D problem-solving efforts, businesses can use various methods such as:

• Key performance indicators (KPIs) that can be used to quantify the results or outcomes of 8D problem-solving initiatives. Some examples of KPIs are customer satisfaction scores, defect rates, cycle times, or cost savings.
• Data collection and analysis tools that can be used to gather and interpret data or information related to 8D problem-solving initiatives. Some examples of data collection and analysis tools are surveys, audits, control charts, or statistical process control (SPC).
• Periodic reviews and feedback mechanisms can be used to monitor and evaluate the progress and performance of 8D problem-solving initiatives. Some examples of periodic reviews and feedback mechanisms are reports, presentations, meetings, or feedback forms.

By measuring the effectiveness of 8D problem-solving efforts, businesses can ensure that they are continuously improving their quality, efficiency, and customer satisfaction.

What is 8D Problem Solving? Complete Guide For 2024

Problem-solving is now becoming essential for companies to stay ahead of the competition. 8D problem solving is one of the most popular methodology used in all industries for solving technical problems at the workplace.

This methodology uses many of the tools from six sigma but focused on identifying, correcting, and preventing a problem. This methodology is not part of six sigma but they do help in many situations to structure the problem-solving process and find its solution. 

In this article, we will understand the 8D problem solving methodology in detail along with a case study example so that at the end you will become ready to implement it. Let’s start…

Table of Contents

What is 8D problem solving methodology – 

Before getting into this let’s understand the simple question, what is meant by a problem?… A problem is a situation you want to change or it is an opportunity for improvement, right!

In the context of Six Sigma, the problem is nothing but the out-of-control situation, waste in the process or special causes of variation, etc.

Generally, there are two causes of variation which are responsible to disturb any process i.e.  Special cause of variation and a common cause of variation. The focus of any problem-solving tool is to reduce these variations as much as possible.

Suppose, If we plot the control chart, in that any data point that is beyond the upper and lower limits indicates that the process has special causes of variation, and when all the data points are within these limits that means our process has only a common cause of variation.

Common causes of variation are an integral part of any process, they cannot be eliminated completely from the process.

We can reduce it up to a certain level so that the process performs effectively and efficiently. Six Sigma methodology is useful to reduce these common causes of variation by using the DMAIC process . 

But when there is a special cause of variation in the process, it is an indication of disturbances in the process which then increase the variability of the process beyond acceptable levels.

These causes of variation must be eliminated from the process to make it stable. Here comes the use of 8D problem solving methodology. This 8D methodology is useful to eliminate all the special causes of variation to bring long-term stability to the process.

Six Sigma   – Useful in reducing common cause of variation. 8D problem solving – useful in eliminating special cause of variation.

This problem-solving methodology is designed to define the problem in the process and find the root cause of that problem. It focuses on implementing a long-term solution to prevent the reoccurrence of the problem.

History of 8D methodology – 

8D has its origins in the united states military and also in the automobile industry but nowadays it is extensively used in all industries like food processing, healthcare, tech manufacturing, services, etc.

In 1980, Ford Motor Company developed team-oriented problem solving which then become an 8D problem solving methodology.

Due to its effectiveness, it was accepted as a primary method of problem-solving at Ford. After it becomes popular at Ford and because of its effective results, 8D methodology was globally accepted as the best problem-solving method to tackle engineering problems.

The name 8D stands for the disciplines covered in this methodology or the 8 steps of problem-solving. These steps are identified as D0 to D8 and it follows the PDCA cycle (Plan – Do – Check  – Act).

The goal of this method is to find the root cause of a problem, develop containment action to protect customers, and take corrective action to prevent similar problems in the future.

What are the 8 disciplines of 8D problem solving – 

8D methodology is the combination of 8 steps or disciplines starting from D1 to D8 in which professionals work together to solve problems and create effective solutions for that problems.

Initially, it is comprised of 8 stages of problem-solving later it is updated with the initial planning stage D0 so now 8D becomes D0 to D8 steps.

This is a very structured and highly disciplined methodology of problem-solving which drives systematic changes or improvement in the process by preventing problems.

We will discuss how this 8D problem solving works later in this article but for now, Let me list down all the steps of this powerful method.

When to use 8D problem solving – 

This powerful problem-solving methodology is required when…

• There is a need to find a permanent solution to the problem and prevent the recurrence of that problem.
• There is a need to develop containment action to protect customers, and take corrective action to prevent similar problems in the future.
• Customer complaints are received (when they are unhappy with product/service performance.)
• There is more amount of internal rejection, waste, and scrap in the process which makes process performance poor.
• There is a failure in a system or in a process beyond the acceptable levels.
• There is safety or regulatory issues that occurred.

How to apply eight disciplines of (8D) problem-solving –

Now let’s get into the depth of each discipline and understand what will happen in each discipline and as problem solvers what you need to do – 

D0 – Prepare and plan for 8D – 

Proper planning is important to implement 8D problem solving successfully. This stage is all about finding the problems and prioritizing them.

You may find multiple problems and all seem to be urgent hence main task here is to identify the main problem on the basis of its impact or importance and the urgency to resolve it.

We need to properly understand the customer complaint data and then check which complaint needs an emergency response to protect the customer from further consequences.

At this stage, we can use tools like Pareto analysis to select and prioritize the problem. This tool gives us a clear picture of the problem and tells us where we need to do the investigation.

At the time of the planning stage, we need to consider – 

• Who will be on your team?
• What is your time frame?
• What resources will you require?
• Is it a new problem or already occurred?
• What is the history of the problem?
• If it occurred before then how it was solved at that time?

D1-Grab a team 

To implement this team-oriented problem-solving methodology we need a cross-functional team of quality professionals, process owners, subject matter experts, team leaders, and sponsors. This stage is all about forming a team of people with product or process knowledge.

The team leader should be the person who has the right expertise to solve problems and knows how to implement the 8D process or the person who works close to the process i.e. process owner. Then there is an 8D moderator or SME, the person who is trained in 8D and guides the team by giving them feedback.

On the other hand, the Sponsor is responsible for resources and they support the team in any financial decision-making and give the authority to implement corrective action.

And at last, there are team members who are experts assigned to work on the problem with their specific knowledge. Time and resources are allocated to them so that they can work on the problem as per the 8D problem solving process.

List of team members who are generally part of this project –

• Process owner
• SME’s
• Quality engineers
• production staff
• Team leader

D2-Understand the problem

A properly defined problem is a half-solved problem. At this stage, describe the problems in such a way that it is easily understood and can highlight the issue faced. While highlighting the problem you need to focus on Where, When, and How.

For Where type questions ask like where did the problem occur? which site of the company? which location in the company or which process line has a problem etc. Is the problem with a single process/product or does the entire batch have a problem? etc.

For when type questions ask like when was the first occurrence of the problem? Is there any time pattern? Does it occur after every cycle, every day, or every shift? Focus on when exactly the problem occurs.

For how type question ask like how many products affected? how many processes have these problems? All the answers to such questions must be based on facts and exact data. This helps to understand the exact problem.

Understanding the problem becomes easy when we focus on these types of questions. We can use tools like cause & effect diagrams, 5 why analysis, or affinity diagrams to get more information about the problems.

D3-Take containment action

At this stage, we need to define and implement the containment action that will protect the customer from the problem.

It is the temporary action implemented till permanent corrective action is implemented and validated. This action will be discontinued after the positive results of the validation of permanent corrective action.

It is the quick fix of a problem for example- S hutdown of the machines that are not working. So that we can stop the production of defective parts. That means the target of this action is to protect customers from future consequences.

During this stage, we need to maintain communication with the customer because of containment action there may be a delay in the delivery of the product so discussion with them helps to maintain trust.

Examples of Containment action- 

• Stoppage of production.
• Informing the customer about the problem.
• Informing operators about the problem.
• Additional visual control.

D4- Find the Root cause

Identification of the root cause is very important. If it is properly identified, it can be acted upon and recurrence can be prevented from that root cause.

The location of that root cause also needs to be identified. More than one root causes are responsible for the problem.

To identify this we can use tools like root cause analysis, fishbone diagram, 5 why analysis, and Is/Is Not analysis. Well, you are familiar with other tools but Is/Is Not analysis is something new. Let me give you one example to show what this tool is…

For example – If there is a problem and you start assessing the situation with questions starting from Where When etc. we already discussed this.

In this analysis, we look for both sides of the question. Where is the problem and where is not the problem or we can ask when the problem occurs and when it does not occur? This type of questioning helps us to set some boundaries for the problem study.

For example – The problem is in product A and it is not in products B and C these answers we will get and after that, we can only focus on product A for further problem study. That’s how Is/Is not analysis works.

List of tools used for finding root cause- 

• Pareto charts
• Affinity diagram
• Brainstorming session
• 5-why analysis
• Fishbone diagram
• Fault tree analysis
• Statistical analysis
• Hypothesis testing
• Regression analysis

D5- Choose permanent corrective action

Permanent corrective action is the action that removes product/process/system condition which is responsible for the generation of the problems. The determination of this permanent action is dependent on the root cause identified in the D4 stage.

Basically, at this stage, we want to remove the root cause of the problem by choosing effective permanent action.

There can be more than one permanent action so to choose the best from it we can brainstorm with team members also we can use the affinity diagram tool.

During brainstorming, team members look for acceptance criteria to select the permanent action, they evaluate the risk associated with the particular permanent action and make a balanced choice. Hence the goal of this stage is to remove the cause & effect link completely.

Criteria for choosing the best corrective action or solution for the problem – 

• Practical – 8D team should be able to implement the solution practically.
• Feasible – The solution must be feasible. 
• Cost-effective – Implementing and using the solution must be cost-effective.
• Robust – The solution must be robust so that it should not fail when it is implemented practically.

Examples of permanent corrective action – 

• Introducing additional control in the process.
• Rework defective units found in the process.
• Rework units returned from the customers.
• Inform the supplier about defective parts delivered and their exchange.
• Implement visual control at the workplace.
• Implement Poka-Yoke

D6- Implement and validate corrective action 

Once the permanent corrective action is determined it is implemented and for effective implementation, we need to focus on proper planning. We need to create an action plan that includes information like what steps are needed to implement the solution, who will do them, and when they will be completed.

Communicate the action plan and all the changes with team members as well as with people who are working in that area and make sure everyone in the team follows the action plan and tracks results.

At this stage, we also need to prove the effectiveness of the permanent action. After its implementation, we have to recollect the response data about that process.

Service or sites to understand how this permanent solution works. That means we have to verify the effectiveness of the solution.

Then accordingly team updates all the documentation plans, work instructions, and failure effect analysis data once the validation of corrective action is done. That’s how this stage completely focuses on the implementation and validation of the solution.

List of tools used during this stage – 

• Check sheets
• Control charts

D7- Learn and define prevention for the future 

This stage is more like the control phase of the DMAIC project where we need to control the improvements made on the process and ensure that gains obtained during the project are maintained long after the end of the project.

Similarly, at this stage of 8D problem solving, the team focuses on the active prevention of the reoccurrence of the problem. They review similar services/products or processes in the company to prevent a recurrence.

The team actively presents the 8D methods to experts at other process lines or at other sites of the company so that they can actively work on the prevention of problems.

Process owners and upper management work together to share the learnings of 8D across the company and execute 8D training at different processes or product lines. These learning documents consist of updated procedures and work instructions for the prevention of problems.

Also, the team develops a new set of standard operating procedures that everybody needs to follow who works in that area or at the process line, etc. in order to prevent the recurrence of the problem.

They proactively update the failure mode effect analysis document and control plans because these two tools help us identify the problem area and then prevent its occurrence. 

• Control plans
• Capability analysis

D8- Congratulate and release the team

This stage is one of the most important disciplines of 8D problem solving , here the team leader should recognize the team and individual efforts, recognize those who perform best during the project, and then congratulate all the team members as well as the main contributors to this project.

Recognition is important because we don’t know when we need these team members again so if the team leader appreciates their effort at the end of the project then team members feel motivated and they will be always ready to work with the leader in the future.

After this team leader declares the formal closure of the 8D project by documenting all the lessons learned. Finally, all the documentation is completed in the form of an 8D report which is available for all the employees at the company for learning purposes. 

This stage is all about the documenting final 8D report and celebrating the successful completion of the 8D project.

That’s how the 8 disciplines of 8D problem solving methodology work. The most important part of this method is the 8D report which consists of a quick summary of the entire problem-solving project. Now let’s see what the 8D report means…

What is 8D report?

The output of an 8D project is the 8D report and this is first used in the automotive industry. Here we will go through a basic example of the 8D format in order to understand what it includes and its structure. 8D report has 3 parts let’s see them one by one…

In the first part (as per sample 8D report picture), we have to fill in our company information like name and logo. Then, we have to fill in information about the parts/process where we performed this project and the date(when the problem occurred).

After that in the next section, we have to fill in information about the problem basic like whether the problem occurred for the first time or it is repeated and how much severity it has.

Then in the next section, we have to add the team member information like their names and sign. After that in the next section, we have to add detailed information about the problem.

Then there is a section of containment action, in which we have to add what type of containment action we have taken to avoid more damage. Provide details about containment action.

In the second part (as per the sample 8D report picture), initially, we have to add our cause & effect diagram with a detailed analysis that includes all the possible causes classified into different categories.

After that, there is a section on the Root cause, see during cause & effect analysis we found the possible causes and then we segregated potential causes from that. By using tools like 5 why analysis, we found the root causes of all these potential causes, that root cause information we have to add in this section.

Then in the next section, we have to add information about the corrective action which we have taken to prevent the occurrence of the problem.

Next to that section, we have to add validation results of corrective action, after testing the correction action and how it works, that information we have to include here.

In the third part (as per the sample 8D report picture), We have to add a list of the preventive action taken. Next to it, we have to add information about all the documents created during the project like a list of documents and the name of updated documents.

After that, we have to add evidence of the final results like photographs, graphs, control plans, etc. At last, there is a section on problem closure and sign-off, which includes a summary of all 8 disciplines or 8D steps like the start and end date of each step.

Then there is sign-off from all the team members which shows this project successfully completed. At the bottom mention the total time required to complete the 8D project .

This is the basic structure of the 8D report , it is different for different companies so there is no standard for it you can select as per your company. I hope you got the basic idea of the 8D format. (Check out 8D report template )

Benefits of 8D problem solving method- 

8D is the structured and highly disciplined methodology of problem-solving. Proper implementation of this methodology can provide the best results. It is easy to learn and applicable to solving any type of engineering problem. Here is the list of benefits of 8D problem solving – 

• This methodology builds a culture of team-oriented problem-solving instead of individual problem-solving. Inspire the employee to work together in a team to solve any engineering problem.
• It improves the awareness amongst the employees as well as management about understanding the problems and ways to find solutions.
• It increases customer satisfaction, profitability, and market share of a company.
• It increases the practical understanding of Root cause analysis.
• It increases the understanding of statistical tools amongst the employee that are used in problem-solving. 
• It improves the skill of implementing permanent corrective action and validates its results.
• This methodology helps to create a proper action plan to prevent the reoccurrence of problems in the future and engage everybody in this process.
• This methodology helps in bringing about systematic change rather than just quick fixes.

8D problem solving case study – 

Until now we discussed everything about 8D problem solving so it’s time to understand how it works practically. With this case study, we will understand How the 8 disciplines of the 8D methodology work. Lets’ see – 

Practical implementation of 8D at car washing center. (Scenario)

“ TATA motors have a car wash service center in Bombay city (Bombay – a popular city in India). TATA motors recently ran into problems with some of their customers which causes damage to their reputation.

Also, they have built over a long period, incurring financial damages from litigation from angry customers and losing their loyal customer base to their competitors.

Recently, the shift operator discovered that some of the cars coming out from one of three car wash machines have scratches on the rear body. The problem was fixed by calling a technician.

But again after two weeks, the problem started re-occurring, and this time the scratches were even more worst. This was discovered by the evening shift operator who notified the supervisor.

TATA motor’s head office sends the quality control supervisor to the car wash center to deal with this problem. After analyzing the situation he came to the conclusion that to properly solve this problem we have to use the 8D problem solving approach.

To prevent further damage to the machine, the quality supervisor immediately instructed the operator to shut down the faulty car washing machines. Customers were already waiting to resolve this problem. 

The quality supervisor invited the engineer, operator, car wash center supervisor, and service technician to a brainstorming session. Everybody on the team knows that due to this problem our company facing negative feedback from customers.

During the brainstorming session, they discussed the questions like who discovered the scratches? What did those scratches look like? when it was first noticed? after how much time it re-occurred? etc. Everybody on the team puts their own opinion during the discussion.

At the end of a brainstorming session, they gather the data and the team comes to the conclusion that the problem is due to the malfunctioning of a particular sensor in the machine.

The engineering team looked into this and found that the machine had a sensor calibration problem in which the sensor periodically malfunctioned.

They found the problem and now the team wants to know the reason behind that problem so that they can find a permanent solution for that.

After performing a Root cause analysis they found that this problem happened due to the annual servicing of the machine being 4 months late.

To fix this problem, the 8D problem solving team instructed the car washing center supervisor to call a specialist to do servicing of problematic machines and repair or replace that non-functioning sensor.

After fixing this, the team collected the data of that machine (which had a sensor problem earlier) in order to validate whether that machine working properly or not.

After 9 hrs the machine was continuously tested and as a result, it was found that there were no scratches, and cars were washed from the center there were no new reports regarding the scratches. 

In order to address the angry customers, the 8D team suggested a car wash center to give them some concession for car washing and respond to all their feedback.

Then 8D team created an action plan or strict guidelines for the servicing procedure of all the 3 car washing machines to prevent the recurrence of the problem. All the important lessons learned during this project have been documented for future reference.

In the end, the quality supervisor who is the team leader of this 8D project appreciated all the teammate’s efforts and congratulated them on the successful completion of the project.”

This is a complete problem scenario we discussed and now below we documented all these scenarios in the form of 8 disciplines of problem-solving. 

OD – Aware of the problem

A Shift operator discovered that a number of cars coming out from one of the three-car washing machines have scratches on the car body.

1D -Grab the team 

The quality supervisor invited the engineer, operator, car wash center supervisor, and service technician to a brainstorming session in order to discuss the problem.

2D- Understand the problem

In order to come to this conclusion, they studied questions like who discovered the scratches? What did those scratches look like? when it was first noticed? after how much time it re-occurred? etc.

3D -Take containment action 

To prevent further damage to the machine, the quality supervisor immediately instructed the operator to shut down the faulty car washing machines.

4D – Find the root cause 

5d – choose corrective action.

To fix this problem, the 8D problem solving team instructed the car washing center supervisor to call a specialist to do servicing of the problematic machine and repair or replace that non-functioning sensor.

6D – Implement Corrective action

The team collected the data of that machine (which had a sensor problem earlier) in order to validate whether that machine working properly or not.

7D – Prevention for the future 

8D team created an action plan or strict guidelines for the servicing procedure of all the 3 car washing machines to prevent the recurrence of the problem. All the important lessons learned during this project have been documented for future reference.

8D – Release the team 

The quality supervisor who is the team leader of this 8D project appreciated all the teammate’s efforts and congratulated them on the successful completion of the project.

That’s how this problem in the car washing center was permanently solved using 8D problem-solving and in the end, the team created an 8D report for further learning. This example shows how effectively we can apply this methodology to solve technical problems.

Conclusion – 

Well, I hope you got the basic idea about the powerful tool called 8D problem solving. We discussed all the concepts related to this methodology and also discussed the eight disciplines of this method along with what happens during each discipline and which tools we need to use.

We also understood when to use this tool and what are its benefits. We also discussed the concept of the 8D report , and what it looks like. In the end, we covered one basic case study to understand how 8D problem solving works to solve real-life problems.

Practical Problem Solving Tools for Factory and Office

February 5, 2022

Many tools exist to address deviations and defects, but only a few are simple yet effective to address daily issues in manufacturing, development, administration.

When starting systematic trouble-shooting, it is important to choose the right approach. Using a comprehensive method that requires 50 pages to solve a simple problem is a waste of time, while solving a complex problem with a simple tool will most likely not reveal the hidden causes. The optimal choice of Problem Solving Tools depends on the type of issues to be addressed. Before going into details, let’s first review the most common methods used today.

Comparing Popular Methods: 3W, PDCA, 8D, A3, DMAIC, 7STEP

At their core, all scientific approaches follow a similar logic: take quick action to prevent the problem from getting worse and then define the gap, analyze the gap, identify causes, take action, evaluate impact, and embed the solution so that the problem will not reoccur. 

• 3W : When the issue is small and the solution is obvious, a formal analysis is not required. The 3W-method defines  What  to do,  Who  to do it, by  When . This “quick-fix” or “just-do-it” is commonly applied at daily team meetings to contain and correct snags and minor issues.
• PDCA : The Deming or Shewhart cycle “Plan-Do-Check-Act” is the classic method, used by over 80% companies that practice systematic problem solving. PDCA is effective for medium-size problems that require a systematic analysis to uncover underlying causes.
• 8D : The eight disciplines (8D) are commonly used in automotive, and the problem-solving process (PSP) in avionics. Both methods are similar, using 8 steps to address complex problems with focus on a fast reaction to non-conformances, completing the first three steps within three days.
• A3 : The A3-report, developed by Toyota, is an 8-step improvement and problem-solving process that fits on one sheet of paper. The A3-report is most effective to address small- to medium-size problems, and to structure improvement projects.
• DMAIC : The 5-step Six Sigma process “Define-Measure-Analyze-Improve-Control” is a data-centric solving method. DMAIC is used to structure projects and solve complex situations that require statistical analysis to develop the solution, e.g. adjust process parameters to reduce yield loss.
• 7STEP : This seven-step (7S) problem-solving process shares elements with the A3 and 8D, but does not include a formal step for containment. Because of this weakness, the 7STEP process is rarely used today, replaced by 8D to address major deviations and PDCA for smaller issues.

Comparing the most-popular processes for trouble-shooting and root-cause analysis shows how similar they are. For example, the PDCA planning phase covers the first three steps in DMAIC and the first five steps in A3 and 8D. Of all those processes, there are two that stick out, that all others are based on – PDCA and 8D – they are therefore considered the “mother” and “father” of practical problem solving tools used today.

Answer 5 Questions to Select the Best Method

When it comes to choosing the right process, it merely depends on the complexity of the situation to address. The more complex or severe, the more formal steps should be applied to make sure no step is missed. Here are five questions that will help you selecting the best process:

• Is the issue small, medium, or large?
• Is the solution obvious or unknown?
• Is it reoccurring or a single incident?
• Is it a single cause or multiple causes?
• Is statistical data analysis required?

3 Practical Problem Solving Tools: Fix, Fish, Tree

There are three practical, yet effective tools to address daily issues in factory and office: The 3W or “Fix” because it is quick, simple, informal;, the PDCA or “Fish” because it is based on the Ishikawa or Fishbone diagram;, and the 8D or “Tree” because it uses logical trees to analyze complex root causes.

• Fix: use 3W (What-Who-When) for informal trouble-shooting , finding a quick action to fix a small issue within a day .
• Fish: use PDCA (Plan-Do-Check-Act) to analyze simple and repeat issues within a week , using the fishbone diagram.
• Tree: use 8D (Eight Disciplines) to systematically eliminate multiple root-causes or complex problems within a month .

Tools and Templates to Eliminate Root Causes

To encourage people to go beyond containment and quick fixes, the method they use must be simple and practical, but also effective and efficient. Over the course of several years, we have tested dozens of different templates and found that the following two forms work best by far. Why? Because the user is given a clear structure, enhanced with pictograms, and the entire solving process can be completed on a single sheet, the key for broad adoption.

The PDCA and 8D templates have proven to be extremely effective in addressing non-conformances; they are practical problem solving tools for teams in manufacturing, quality control, product development, healthcare, back office, and corporate administration to successfully resolve daily issues and prevent them from coming back.

Use PDCA Template to Solve Simple Problems

4 Steps to Eliminate Simple Causes

• Plan-1 Record Problem : Describe what happened, where and when, and who is involved solving it.
• Plan-2 Analyze Problem : Assign potential causes to categories: Man, Method, Machine, Material, Management, Milieu (Environment).
• Plan-3 Identify Causes : Ask “why” to drill down to root causes; for complex problems, use several forms, one per branch or issue.
• Do Implement Actions : Create and implement an action plan to contain, correct, and prevent the problem from reoccurring.
• Check Results and Act : Review impact, standardize solution; close the case or initiate further actions by starting a new PDCA cycle.

Use 8D Template to Solve Complex Problems

8 Steps to Eliminate Complex Causes

• D0 Plan : Register problem and define emergency response.
• D1 Team : Identify team members to address the problem.
• D2 Problem : Grasp the situation and describe the problem.
• D3 Containment : Prevent the problem from spreading.
• D4 Diagnostics : Identify direct causes and root causes.
• D5 Correction : Define and prioritize corrective actions.
• D6 Validation : Implement actions and evaluate effectiveness.
• D7 Prevention : Systemize solutions to prevent reoccurrence.
• D8 Completion : Transfer knowledge and recognize contributors.

Product defects are not uncommon but an organization must act quickly to eliminate them. This will ensure customers have a good experience and the brand doesn’t suffer. In the event of a complaint, an organization can rely on the analysis of an 8D report sample to address errors and improve quality.

The 8D methodology is a structured and systematic approach to problem-solving. From an 8D problem-solving example it’s clear that it not only identifies a problem but also recognizes the weaknesses in the system. Analysis of an 8D report example prevents future occurrences of similar issues.

Examples Of 8D Reports

8d problem-solving report example, 8d problem-solving example.

An 8D problem-solving example shows the strength of this model lies in its methodology, structure and discipline. Organizations can effectively use an 8D report example to analyze defects, its root causes and ways to implement corrective actions.

Let’s have a look at these 8D reports.  

An organization had a problem with holes appearing in its metal cast toy parts. They found that about 3% of their last batch received complaints after operations due to pin-hole defects. An analysis was submitted after the purchase head asked for a full 8D report example . Here’s a look at the 8D report sample that was submitted.

D1 : Names of team members, team leader and manager.

D2 : The problem reported by the customer is described by answering the following questions:

• What is the problem? A pin-hole defect
• Who reported it? Tulip Pvt Ltd
• When did it occur? Seen in the last batch
• Why did it happen? Due to a defect in the casting base
• How much production is affected? 3% of the products are defective.

  These questions aim to simplify their approach to problem-solving.

D3 : Once the problem is defined, the defective parts are segregated.

D4 : The root cause of the problem is identified by answering the following questions:

• Why is there a pin-hole defect?
• Why are core problems arising?
• Why wasn’t the core cured properly?
• Why was drying/curing time not modified?

These questions reveal that curing time was not validated and that was the root cause of the problem.  

D5 : A permanent corrective plan is recommended to the quality assurance engineer. It is proposed that product and process should be validated for new drying time.

D6 : Permanent corrective actions are implemented. 10 samples are collected. Product and process characteristics of each sample are checked.

D7 : Preventive measures are recommended to ensure the problem doesn’t recur.

D8 : Team and individual contributions are recognized by the manager. The team leader and team members are rewarded for their efforts.  

An organization received customer complaints about shrinkage on an automobile part. The management demanded a thorough analysis based on an 8D problem-solving example . Here’s the 8D report sample that was submitted:

D1 : A team is created with supply team members, team leader and manager.

D2 : A customer complaint is used to describe the problem. The problem is established by answering the following questions:

• What is the complaint? Shrinkage on sump.
• When was it seen? In the last batch.
• Why did it happen? Due to a defect in the entrance area.
• Who reported the problem? Albert D’Souza
• How much production is affected? Nearly 2%

These questions allow the team to devise a containment plan.  

D3 : As a containment action the team decides to stop consignments and segregate the good parts immediately.

D4 : To identify the root cause, the team has to answer the questions defining the problem. They are:

• Why was there a shrinkage at the ingate area?
• Why were high pouring temperatures used?
• Why was the pyrometer reading incorrect?
• Why was the pyrometer condition not checked?

The root cause of the problem is revealed to be a faulty pyrometer.

D5 : As a permanent corrective plan, periodic checking of the pyrometer is suggested to the maintenance supervisor.

D6 : Permanent corrective action is implemented and pyrometers are scheduled for weekly checks.

D7 : Periodic checking and proper maintenance of pyrometers are factors to prevent a recurrence.

D8 : The team effort is recognized. The manager and team are praised for solving the problem.

An 8D report example will show that Root Cause Analysis (RCA) is an integral part of the 8D process. It helps managers establish problem statements, identify potential causes, compare theories and confirm the main cause of a problem. You can establish the root cause in an 8D report example by asking the most relevant questions related to the defect.
