In today’s fast-paced and fiercely competitive business world, organisations must find ways to continuously adapt, evolve, and excel. Amidst the myriad methods and techniques for achieving improvements and driving continuous improvement , few have proven as profound and transformative as Toyota’s A3 problem-solving approach. 

A significant driving force behind the company’s rise to global prominence, the A3 process fosters a culture where problems are embraced as opportunities for growth and learning. In this article, we’ll explore the origins and underlying principles of the A3 approach and uncover the secrets to its success in unlocking the power of improvements.

Understanding the A3 Approach

The A3 methodology is an integral part of the Toyota Production System (TPS), a set of principles and practices that have shaped the company’s approach to manufacturing, management, and continuous improvement over the years. Named after the A3 sheet of paper that was historically used to capture the plan, analysis, and follow-up on a single sheet of paper, typically an A3-sized sheet, the A3 process represents a simple, yet powerful, tool for addressing complex challenges and discovering lasting solutions.

At its core, the A3 approach is rooted in three key elements:

Thorough problem analysis : The foundation of the A3 process lies in digging deep to diagnose the true nature and root cause of an issue, rather than jumping to hastily devised fixes that merely address symptoms.

Structured documentation: The A3 report serves as both a communication tool and an iterative planning device, with each section building on the previous ones to guide problem solvers through a comprehensive analysis, solution development, and execution process. It’s the foundation of good continuous improvement.

Cyclical learning and improvement: Leadership and employees alike are encouraged to commit to hypothesis-driven inquiry, observation, experimentation, and reflection, leading to a culture that actively seeks and leverages opportunities for growth by solving problems.

How to Implement the A3 Process in Your Organisation

The Lean Thinking A3 approach can be distilled into seven essential steps:

1. Identify the problem: 

Clearly articulate and define the issue at hand, avoiding the temptation to jump to solutions or assume important facts to be self-evident..

When identifying the problem, it is important to ensure that all relevant stakeholders in the organisation are consulted. This helps to ensure that the issue is accurately described and understood from multiple perspectives. A thorough problem analysis should also include conducting research into possible causes or root issues, and clearly documenting any observed symptoms of the problem. Additionally, it is essential to identify any major risks associated with not finding a solution and recognise any constraints (both external and internal) that may exist which could limit potential solutions. Lastly, it is important to consider any potential opportunities which may arise from addressing the issue that may have been overlooked at first glance. This is the problem statement part which is a critical component that identifies the difference between the current condition and the target condition.

At this stage, we are not looking at how to solve problems being faced or at the potential solution to solving problems. It’s about developing a good understanding of how the actual results differ from the expected results and providing an in-depth systematic approach to process improvement and developing problem-solving skills.

2. Establish the context and background: 

Provide a high-level overview of the problem, describing the stakeholders involved, relevant data, and the broader organisational context in which the challenge has arisen..

It is important to ensure that all stakeholders are properly considered when identifying any potential solutions as their perspectives can play a vital role in determining an effective solution. All related data should be thoroughly analysed to understand the full scope of potential solutions. This includes resources, costs, timelines, and any legal or regulatory issues that may need to be considered. Additionally, it is important to consider how well-proposed solutions fit within existing organisational policies and procedures as this could impact implementation success. Finally, understanding how proposed solutions would interact with other initiatives or processes currently taking place in the organisation can help inform decisions about whether or not they are viable options. It may include conducting some value stream mapping to dig deeper into the current state.

It is important to fully explore any underlying factors that may be contributing to the issue at hand and ensure in-depth problem analysis. This includes looking deeper into existing systems, structures, and processes related to the problem in order to identify potential areas of improvement or optimisation. Additionally, it is essential to consider any relevant industry trends or external influences that could impact how the problem manifests within the organisation.

When analysing a problem, collecting data from various sources is important to get a more comprehensive understanding of how a particular issue can be addressed. This includes mapping the current process using the VSM, SIPOC , Process Mapping or Flowcharting techniques. Additionally, interviews and surveys can be conducted with stakeholders to gain insights into how they perceive the issue and their perspectives on potential solutions. Lastly, it is important to observe any real-world activities related to the problem to uncover key areas where time, effort, resources, money etc is being wasted. This is the time improvement that may not have been identified otherwise.

This involves clearly articulating the desired state of affairs and any key deliverables of the proposed solution. Whether it is reducing operational costs, increasing efficiency, improving customer experience, or something else entirely – defining specific objectives with measurable metrics can help ensure that project teams stay focused and remain aligned on their ultimate destination.

At this stage, it is also important to consider how long it will take to reach the desired outcome. Establishing an implementation timeline will help safeguard progress and provide a framework for tracking results along the way. Setting milestones for achieving particular goals at certain points in time can be especially helpful in keeping teams accountable throughout the process. Additionally, having a plan for evaluating success after reaching the end target will allow stakeholders to gain further insights into how effective their approach has been in addressing underlying problems, as well as how well-proposed solutions have fared once implemented.

4. Investigate root causes:

Use a variety of techniques (e.g., the 5 whys, fishbone diagrams, pareto charts) to probe the problem’s underlying causes and avoid settling on proximate reasons..

The process of identifying root causes is essential when using data-driven tools. We always want to find the simplest root cause approach.

One of the most widely used methods for root cause analysis is the ‘5 Whys’ technique. This method involves asking a series of ‘why’ questions to determine the underlying cause of a particular symptom or issue. The goal is to keep asking “Why?” until you reach an answer that can provide insight into how to address the problem and prevent it from occurring in the future.

Another commonly used tool for root cause analysis is the fishbone diagram (also known as Ishikawa diagrams). This approach involves visualising all potential causes which could be causing a symptom or issue in a logical format, allowing users to identify patterns and uncover links between root causes and their respective effects. This technique can be helpful in identifying and focusing on key areas for improvement, as well as helping to identify interdependencies between components within an organisation’s systems.

Finally, Pareto Charts are useful for analysing data collected from surveys, interviews, observations, etc., concerning the severity or frequency of occurrence. This type of chart helps users quickly identify which factors are contributing most significantly towards an issue, allowing them to focus resources towards addressing those areas first and foremost. Additionally, Pareto charts can also be used to prioritise different solutions based on their estimated effectiveness in addressing an issue.

In conclusion, understanding the root cause of an issue through rigorous techniques such as 5 Whys, fishbone diagrams, and Pareto charts provides invaluable insight into how best to address it effectively while preventing it from reoccurring in the future. By leveraging these tools along with other data-led approaches such as process mapping and flowcharting, organisations can ensure that any proposed solutions are well-informed by both qualitative and quantitative data sources as well as ensure they are building consensus across the entire organisation.

5. Countermeasures:

Identify the right countermeasures (corrective actions) to implement that will directly impact the root causes identified..

Brainstorming is a useful tool for identifying potential improvements. It involves coming up with ideas and solutions in an open and collaborative manner, without judgement or criticism. By allowing team members to share their thoughts freely, brainstorming can help uncover innovative solutions that may have otherwise gone unnoticed. Additionally, looking at how waste reduction, flow and pull can be used to improve processes can also provide valuable insights into where improvement opportunities lie.

Brainstorm potential solutions that directly target the root causes and create detailed action plans for implementation, complete with assigned roles, responsibilities, and timelines.

Once the countermeasures are identified, it is important to design an implementation plan and assign roles & responsibilities. This will help ensure that all stakeholders understand their part in the implementation and can work together to achieve the desired outcome. Additionally, it is important to track progress along the way – setting measurable milestones that can be tracked against goals established during the initial problem-solving phase will help keep teams accountable and allow for course corrections if needed.

By utilising A3 Problem Solving Tools such as a template, organisations can easily document and share their analyses with relevant stakeholders throughout each stage of the project. Having detailed record-keeping like this also helps teams stay on target over time while providing insights into how proposed solutions may need to be re-evaluated down the line. This implementation plan provides the entire organisation with a clear project status on a one-page report.

6. Evaluate the results:

Measure the impact of your countermeasures against the problem, using well-defined success criteria, key performance indicators, or other relevant metrics..

Once the countermeasures have been implemented, it is essential to measure and evaluate their success. This can be done by tracking performance against the initial objectives established during the goal phase, as well as establishing key performance indicators to gauge how well the proposed solutions have fared.

Additionally, stakeholders should also consider conducting a post-implementation evaluation in order to assess how successful their approach has been in addressing underlying issues and determining what lessons can be learned from the experience. This will enable teams to identify strengths and weaknesses within their existing processes and make any necessary adjustments going forward. By understanding the outcomes of their improvements, organisations are able to gain valuable insights into how well they’ve succeeded in achieving their goals and ensure continued success moving forward.

Once the countermeasures have been implemented and their success measured, it is important to compare the results against the initial objective. This can be done in a variety of ways, including graphical analysis such as charts, process maps or flow diagrams. Graphical analysis helps to visualise the differences between results achieved before and after the implementation of new measures in a meaningful way. It also provides an increased level of clarity when assessing whether the desired outcomes have been achieved or not.

Process maps can be useful in understanding how changes made during the improvement phase have impacted processes within an organisation. By mapping out existing processes and then comparing them against those following implementation of countermeasures, teams can easily pinpoint where improvements were made and analyse how they led to improved performance overall.

Charts, on the other hand, enable users to quickly identify trends that may have emerged from data collected during the project. For example, if performance metrics are tracked before and after countermeasures are implemented, users can use charts and graphs to more clearly observe any patterns that may indicate an improvement or regression in performance over time – providing further insights into which areas need further attention or adjustment moving forward.

Finally, dashboard views provide an effective means of displaying results at a glance while highlighting any anomalies that might warrant further investigation. Dashboards allow stakeholders to gain access to important information quickly and easily while also helping them keep track of progress towards goals set out during initial problem-solving phases. Additionally, because dashboards support data visualisation capabilities they offer a highly interactive user experience which can help teams understand underlying trends with greater clarity and precision.

7. Standardise and share:

If a countermeasure proves successful, integrate it into the organisation’s standard operating procedures and share it with other teams as a best practice..

Once the countermeasures have been successfully implemented and measured against the initial objectives, these changes need to be integrated into the organisation’s standard operating procedures (SOPs) and shared with other teams as best practices. This will ensure that any improvements made during the problem-solving phase are consistently applied across all teams within the organisation.

In order to ensure that these improvements become part of the organisation’s long-term strategy, process maps should be updated to reflect the new improved way of working. Process maps provide a visual representation of how workflows are structured within an organisation, and by updating them in line with newly-implemented countermeasures, organisations can ensure that their processes continue to remain up-to-date and efficient moving forward. It may also be necessary to build a follow-up plan if not all tasks are fully completed as well as develop a Lean-focused PDCA cycle to ensure long-term effective collaboration on the solutions that were implemented.

Process documentation should also be updated in order to keep track of changes made during problem-solving. By documenting not just the solutions that were proposed but also why they were proposed, teams can gain valuable insights into their decision-making process which they can leverage for similar future problems.

Furthermore, it is important to update key performance indicators (KPIs) to accurately reflect any progress made during problem-solving. By tracking performance against objectives established before and after countermeasures were implemented, organisations will be able to identify any areas that may still need improvement or require further adjustment going forward. Additionally, tracking KPIs over time will help teams understand whether or not their current strategies are leading them towards meeting their goals in a timely manner or if additional measures may need to be taken in order to achieve desired results more quickly.

Finally, organisations should share successful solutions with other teams in order to promote collaboration and knowledge sharing amongst stakeholders throughout different parts of the business. This will allow for ideas generated through one team’s problem-solving efforts to benefit multiple departments – helping foster creativity and innovation while ensuring that everyone is on board with necessary changes being made throughout the organisation. The last step is key to Toyota’s PDCA management system designed for the entire organisation.

By breaking down the problem-solving process into these seven discrete stages, the A3 method offers practitioners a comprehensive, end-to-end framework for tackling complex challenges and driving improvements in any organisation.

A3 Thinking: A Structured Approach to Problem Solving

• 5 MINUTES READ

Also known as A3 Problem Solving.

Variants include 8D and CAPA.

A significant part of a leader’s role involves addressing problems as they arise. Various approaches and tools are available to facilitate problem-solving which is the driving force behind continuous improvement. These methods range from the advanced and more complex methodologies like Six Sigma to the simpler and more straightforward A3 thinking approach.

The power of the A3 approach lies in its systematic and structured approach to problem-solving. Although it appears to be a step-by-step process, A3 is built around the PDCA philosophy. It relies on the principle that it is much better to address the real root-cause rather than trying to find a solution. Hence, it’s important not to jump to the solution when solving a problem as it is likely to be less effective.

A3 thinking provides an effective way to bring together many of the problem-solving tools into one place. For example, techniques such as the 5 Whys and fishbone analysis can be used during the ‘Analysis’ stage to help identifying the root causes. Additionally, visual aids and graphs are highly recommended in the A3 report, as they are more effective than text in communicating ideas and providing concise project updates.

A3 thinking involves the practice of consolidating the problem, analysis, countermeasures, and action plan onto a single sheet of paper, commonly an A3-sized sheet. This brief document serves as a summary of the project at hand and is regarded as a valuable storytelling tool for project communication. Utilizing the A3 approach doesn’t require any specialized software or advanced computer skills. You may however use readily available A3 templates , or rely on basic tools such as paper, pencil and an eraser as you will need to erase and rewrite several times.

One of the characteristics of the A3 approach is that it does not get into specific details. Detailed documents are usually attached to the A3 report to prevent overwhelming the reader with an excess of information.

The A3 process is typically structured in multiple stages based on the PDCA model. The primary focus is on developing understanding of the current situation and defining the desired outcome before thinking about the solution. While the exact number of stages may vary depending on the preference of the company, what truly matters is adhering to a structured approach to problem-solving.

A3 Seven Stages Model

An A3 process is often managed by an individual who should own and maintain the A3 report. This individual takes the lead in steering the process, facilitating team involvement, and preparing the A3 report with team input. One of the most common models for A3 thinking is the seven stages model which is described in the following.

1. Background – The first step is to identify the business reason for choosing this problem or opportunity. In this stage, you need to identify the gap in performance and the extent of the problem.

2. Current situation – The purpose of this stage is to document the current state of the problem. You may need to refer to the process map or go to the Gemba to truly understand the current situation.

3. Target – The purpose of this stage is to define the desired future state. Clearly identify the expected benefits from solving the problem, the scope, and the key metrics that will help measure the success of the project.

4. Analysis – The objective of this stage is to conduct an in-depth analysis of the problem and understand why it’s happening. It might involve tools like the 5 Whys and cause-and-effect analysis, as well as advanced statistical methods.

5. Countermeasures – Countermeasures are the actions to be taken to eliminate root causes or reduce their effects. The team should brainstorm and evaluate possible countermeasures based on the analysis conducted earlier.

6. Implementation Plan – To achieve the target, develop a workable plan to implement the countermeasures. Gantt charts are great ways to manage implementation plans very simply and easily. Once the action plan is finalized, the team should begin working on the activities needed to implement the countermeasures.

7. Follow-up – The final stage involves evaluating the implementation of the plan and the results achieved. Follow-up actions are important to ensure the benefits extend beyond the project’s completion.

A3 thinking is considered to be the practical form of the PDCA model.

There are many online templates that can be used to manage your problem-solving efforts. One of the simplest and most straightforward ways is to use this A3 problem solving template .

Wrapping Up

A3 thinking represents a logical and structured approach for problem solving and continuous improvement. This approach can be used for most kinds of problems and in any part of the business. Originating from the Toyota Production System (TPS), it has been adopted by many Lean organizations around the world.

A3 thinking not only provides a systematic approach for problem-solving. The development of a continuous improvement culture is at the core of A3 thinking. It has become one of the most popular Lean tools today where people and teams work together to solve problems, share results and learn from each other.

A guide to the A3 problem-solving framework

Have you ever found yourself in a situation where you were faced with a problem and didn’t know where to start? While this can be a daunting scenario, there are a number of frameworks you can leverage to take some of the guesswork away and set up a process for approaching these in the future. One of these is the A3 problem-solving framework developed from Toyota’s lean manufacturing practices.

The A3 problem-solving framework uses a structured approach to address complex problems and gets its name from the A3-size paper used to document the process. With it, you can diagnose the root cause of complex problems and resolve them efficiently.

This article explains the A3 framework, how to use it for problem solving, and accompanying best practices.

Understanding the A3 framework

The A3 problem-solving framework is a structured approach that uses a single A3-sized sheet of paper to document the entire problem-solving process. It includes several key components:

• Background — Context and importance of the problem
• Current conditions — Detailed description of the current state
• Goal statement — Clear objectives to achieve
• Root cause analysis — Identifying the underlying causes
• Countermeasures — Proposed solutions to address the root causes
• Implementation — Steps to put the solutions into action
• Follow-up — Evaluation of results and future actions

The A3 framework offers several benefits. Think of it as a structured approach to problem-solving. Using it will promote clear documentation, and improved communication among team members.

Step-by-step guide to A3 problem solving

There are a few key steps to correctly apply the A3 problem-solving framework. Each structured step guides you through the entire process. It helps you develop the skill of identifying gaps and proactively resolving issues.

Each step also builds up the understanding of the problems:

Here are the key steps involved:

• Step one — Clearly define the problem and understand its background and current conditions
• Step two — Use techniques like the 5 whys and fishbone diagrams to identify the root causes
• Step three — Brainstorm and develop effective countermeasures to address the root cause
• Step four — Follow best practices to implement the chosen countermeasures and ensure stakeholder buy-in
• Step five — Track the implementation, evaluate results, and ensure continuous improvement

This method resolves the immediate issue effectively. Additionally, it lays the groundwork for ongoing improvements and sustainable long-term success.

A3 framework case study

Spotify used the A3 framework effectively to rectify an issue it had with its weekly feature engagement. Its product management team applied the process to identify and resolve the root cause. In this case, the A3 framework looked like:

• Define the problem — The team noted a significant drop in user engagement with Discover Weekly playlists
• Analyze the root cause — Using the 5 whys technique, they discovered that the algorithm wasn’t personalizing recommendations effectively, leading to irrelevant song suggestions
• Develop countermeasures — The team brainstormed solutions. From refining the algorithm to better account preferences, they considered precise countermeasures
• Implement the solution — They rolled out the improved algorithm in stages. Close monitoring of user feedback and engagement metrics proved game-changing
• Evaluate — Here, the team continuously tracked engagement metrics and user feedback after the update, which led to several iterative adjustments to the algorithm over time

Best practices for using the A3 framework

As a product manager, you should adopt specific best practices to maximize the A3 framework’s effectiveness. These practices focus on documentation, collaboration, and continuous improvement:

• Maintain clear and concise documentation throughout the A3 process. You need to promote a culture of transparency and progress tracking
• Encourage cross-functional collaboration. Involve the right stakeholders to gather valuable data. A good collaboration is based on diverse perspectives and expertise
• Emphasize the need for continuous improvement. Also, regularly revisit the A3 document to update and refine it

By following these best practices, you can leverage the full potential of the A3 framework.

Key takeaways

When it comes to complex issues, implementing the A3 problem-solving framework allows you to solve them systematically and effectively. This structured approach ensures that root causes are identified and solutions are developed and implemented in a timely manner.

The following key pointers will prove useful for your day-to-day reference:

• Clearly define problems and understand the background and current conditions
• Use root cause analysis techniques like the 5 whys and fishbone diagrams to identify underlying issues
• Develop targeted countermeasures and implement solutions with stakeholder buy-in
• Maintain clear and concise documentation throughout the A3 process
• Foster cross-functional collaboration to gather diverse insights and expertise
• Emphasize continuous improvement by regularly revisiting and refining the A3 document

By integrating these practices into your problem-solving strategy, you can tackle challenges head-on. Good luck! And as always, comment with questions.

What is A3 Problem Solving?

A3 problem solving is a Lean approach to reporting issues and presenting ways of addressing them. The simple method, developed by Toyota, bases on documenting a problem, together with its current outcome and a suggested change, on a single sheet of A3 paper (420x297mm), giving it the name. You can use it to make a process change proposal, report on project status, or solve a problem.

A3 takes from the Plan-Do-Check-Act cycle . Though it appears to be a step-by-step process, the method tends to be used iteratively, with the problem and solution sections being cyclically updated.

Taiichi Ōno of Toyota was known for not appreciating reports longer than one page, which helped the proliferation of the A3 approach within the automotive giant’s offices. A3 is similar to the 8D report also widespread in the automotive industry, though typically for complaints management. Furthermore, the ability to quickly discern a problem and understand its solution is innate to Lean values.

Lean emphasizes visualization, with examples in value stream mapping and Kanban’s visual workflows. That made a single-page report presenting what is going on was a welcome addition to a Lean operation.

Through shared use of A3s to solve all problems and plan initiatives, companies can start to operate an A3 system thinking methodology: address difficulties, suggest change, innovate, and curate logical reasoning rooted in the current needs.

Why use the A3 approach to solving problems?

Lean provides a competitive advantage, strategic and operational benefits through its objective to increase the value delivered to the customer and to reduce waste. Engaging in a process that allows the team to find the correct, best solution in the shortest possible time is highly beneficial.

Understandably, some reports and proposals must contain extensive amounts of data, and they have their place in a business environment. But imagine the value and advantage that distilling this information to 1 page has. Consider how much faster decisions can be made based on that. Besides the time savings, the opportunity to use the systematic approach of PDCA supplements the problem-solving skills required to propose accurate solutions.

In preparing for battle I have always found that plans are useless, but planning is indispensable. Dwight Eisenhower

It’s the act of planning that is important, as it spells out all known obstacles, visualizes the action plan, and helps to foresee potential outcomes and issues along the way. While documenting your problem on an A3 piece of paper may or may not yield benefits, the act of implementing A3 thinking is what makes the difference.

The benefits of using A3 thinking are:

• Quicker problem solving through logical reasoning and application of a step-by-step, visual process. Demanding a root cause identification ensures that difficulties are dealt with, not just temporarily masked.
• Easier planning thanks to the application of objective, critical thinking promoted by the A3’s structure.
• Team development through repeated use of a structural tool to find root causes of problems and their best solutions. The use of one tool across all company levels also promotes cross-department collaboration and knowledge sharing.
• Company growth A3 reports help maintain and keep company knowledge on record, helping to sustain good operating policies and build a strong growth culture rooted in solving a company’s actual problems, not abstract ideas.

How to create an A3 report?

Step 1: The title

It should focus on the problem you are trying to solve and not the solution you want to convey. Examples of titles are: “Decrease Team Misunderstanding of Task Instructions” or “Reduce Customer Complaints with Product XYZ” .

Step 2: Background

According to the authors of “Understanding A3 Thinking: A Critical Component of Toyota’s PDCA Management System” , one of the main strengths of Toyota is that they place importance on understanding a problem. Rather than rush onto a solution, Toyota takes the time to precisely understand what is going on. The principle of going on a Gemba walk attests to this need to perceive problems first-hand.

The report’s background section conveys important related facts and how the problem aligns with the company’s strategic objectives. Presenting this right there on the page helps minimize the cost that a board of highly paid executives would need to spend looking at a problem, without a guarantee of them understanding it, nor coming up with the right solution. Consider this checklist for your background section:

• Do I know the needs of my report’s audience?
• Have I provided enough context?
• Does what it presents align with the audience’s strategic goals?
• Can the background be explained in 30 seconds?

Step 3: Current condition

A correct definition and a good understanding of the problem is your path to finding the right solution. That makes working on defining the current condition 90 % of the A3 effort.

The objective here is to make sure everyone is aware of the problem, whether the report documents it appropriately, and whether anyone questions the report’s findings. The use of graphs, charts, or other visual aids is beneficial.

Step 4: Goal

Your target - if you hit it, you know that your problem-solving effort has been a success. But you need to know what metrics will measure success and what the definition of success is. An example could be “reducing customer complaints by 15%, as measured by call center statistics” .

Step 5: The root cause

The focus of the root cause section should be to differentiate between facts and opinions regarding a problem’s cause and effect. You can include your findings from 5 Whys exercises , an Ishikawa diagram , or any other result of your RCA efforts . If the root cause is not defined correctly, the problem will likely resurface, causing waste and negating the Lean principles.

Step 6: Countermeasures

The countermeasures should be the corrective actions to take for the root cause of the problem to be resolved. If not possible - without a process overhaul - you can use containment actions instead to stop the issue from directly impacting the customer. It is OK to address complex problems iteratively, along with the values of continuous improvement .

The section may include a table of the problem causes, actions taken, action owners, and the achieved results.

Step 7: Effect confirmation

Since the A3 exercise bases on the PDCA cycle, this section of your report should show the effort you expended to confirm your findings. The proof that you have indeed solved the problem. For example, software engineers include samples that replicate the bugs and verify they are no longer present after a fix.

If the exercise has not taken place yet, i.e., when you’re presenting a plan to gain approval, you should outline what exercises you will conduct to check if the aim is successful.

Step 8: Follow up actions

The final section should include any other actions that you might want to consider. A principle worth adhering to here is the “Shitsuke - sustain” step of the 5S plan . Consider what you should do to ensure the benefits of this exercise are maintained. And could they possibly be translated to other areas of the company?

An A3 problem-solving report will help you deliver information in a way that provides instant value and can quickly reduce waste.

The most important thing to remember is that the act of Lean problem solving is more important than creating an A3 document that may contain no valid data and be simply a tick on some corporate checklist.

The same is true of all Lean methods and tools - their application alone will not make your company Lean. To truly implement Lean principles, your company culture, thinking, and planning all have to transform.

Mastering A3 Problem Solving: The Essential Guide to Improving Processes and Solving Complex Problems

What is A3 Problem Solving?

A3 problem solving definition.

A3 problem solving is a Lean Six Sigma project management tool that uses a structured problem-solving approach to improve process efficiency and product quality. A3 problem solving is based on the A3 process, a problem-solving methodology developed by Toyota in the 1960s. The process was named after the A3-size paper that was traditionally used to document the problem-solving process. In this blog post, we will discuss the origins of A3 problem solving, its key components, steps to run the A3 Problem Solving process, A3 report preparation, some examples on the A3 Problem Solving, and common mistakes to avoid.

Origins of A3 problem solving

A3 problem solving was developed by Toyota as a means to improve the quality of their products and streamline their manufacturing processes. The methodology was developed in the 1960s by Toyota’s Chief Engineer, Taiichi Ohno. Ohno used the A3 process to document and solve problems within the manufacturing process. Over time, the A3 process became a key component of Toyota’s lean manufacturing philosophy and was adopted by other companies looking to improve their processes and products.

When and in What Situation to Apply A3 Problem Solving?

A3 problem solving is a structured approach that can be used to solve complex problems and improve processes. It can be applied in a wide range of situations across various industries. Here are some specific scenarios where A3 problem solving can be particularly useful:

• When faced with a significant problem or challenge that requires a structured approach to identify the root cause and develop effective solutions.
• When there is a need to improve the quality of a product or service, reduce defects or errors, or address customer complaints.
• When there is a need to streamline a process, reduce waste, or improve efficiency to save costs or improve productivity.
• When starting a new project or product development initiative and there is a need to identify potential issues and develop a plan to mitigate them.
• When there is a need to identify opportunities for continuous improvement and make incremental improvements to an existing process.
• When there is a need to implement changes in a process or system that affect multiple departments or stakeholders and there is a need to ensure that the changes are properly planned and executed.

Overall, A3 problem solving can be used in a wide range of situations where there is a need for a structured approach to problem solving and improvement. By following the A3 process, organizations can identify and address root causes, develop effective solutions, and implement changes that lead to continuous improvement and better outcomes.

Key components of A3 problem solving

A3 problem solving is a structured approach that follows a set of steps to identify, analyze, and solve problems. The key components of A3 problem solving include identifying the problem, gathering data, analyzing the data, developing a solution, implementing the solution, and monitoring the results. A3 problem solving also involves using A3 thinking, which is a mindset that encourages continuous improvement and problem-solving through collaboration and teamwork.

8 Steps to run the A3 Problem Solving process

Running A3 problem solving involves following a structured problem-solving approach to identify and solve problems within an organization. Here is a step-by-step guide on how to run the A3 problem solving process:

Step 1: Clarify the Problem

The first step in the A3 problem-solving process is to clearly define the problem. It’s important to gather all the relevant information, including when the problem occurred, where it occurred, and who was involved. This will help to ensure that everyone involved in the process has a clear understanding of the problem and can work together to find a solution.

Step 2: Break Down the Problem

After clarifying the problem, it’s time to break it down into manageable parts. This step involves analyzing the problem and identifying the specific areas that need improvement. This may involve creating a process map or a flowchart to better understand the issue.

Step 3: Set a Target

The next step is to set a target for what the ideal outcome would be. This involves identifying what success looks like and what metrics will be used to measure progress. The target should be specific, measurable, achievable, relevant, and time-bound (SMART).

Step 4: Analyze the Root Cause

To develop effective countermeasures, it’s important to understand the root cause of the problem. This step involves analyzing the data collected in steps one and two to identify the underlying cause of the problem. This may involve using tools such as the 5 Whys, Ishikawa diagrams, or Pareto charts.

Step 5: Develop Countermeasures

Once the root cause has been identified, it’s time to develop countermeasures to address the problem. This step involves brainstorming potential solutions and selecting the best course of action. It’s important to involve all stakeholders in this step to ensure buy-in and support for the chosen solution.

Step 6: Implement the Countermeasures

With a solution in place, it’s time to implement the countermeasures. This may involve testing the solution on a small scale to ensure it’s effective before rolling it out more broadly. It’s important to document the implementation process to ensure that everyone involved is on the same page.

Step 7: Evaluate Results

After implementing the countermeasures, it’s important to evaluate the results. This step involves measuring progress against the target set in step three and determining whether the countermeasures have been effective. If the results are not satisfactory, it may be necessary to go back to step four and analyze the root cause again.

Step 8: Standardize

The final step is to standardize the solution to ensure that the problem does not occur again in the future. This may involve creating a new standard operating procedure or updating an existing one. It’s important to communicate the new process to all stakeholders to ensure that everyone is on the same page.

In conclusion, the A3 Problem Solving process is an effective tool for addressing problems in any organization. By following the 8 steps outlined in this post, organizations can develop effective solutions that address the root cause of the problem and ensure that it doesn’t occur again in the future.

A3 report generation

One of the key outputs of the A3 process is the A3 Problem Solving report. In this blog post, we will provide a step-by-step guide on how to generate an A3 Problem Solving report based on the 8 steps of the A3 process.

The first section of the A3 report should clearly state the problem that needs to be addressed. It should describe the current situation, including the impact of the problem on the organization and the stakeholders involved.

The second section of the report should break down the problem into manageable parts. This may involve creating a process map or a flowchart to better understand the issue. The goal is to identify the specific areas that need improvement.

The third section of the report should set a target for what the ideal outcome would be. This involves identifying what success looks like and what metrics will be used to measure progress. The target should be specific, measurable, achievable, relevant, and time-bound (SMART).

The fourth section of the report should analyze the root cause of the problem. This involves analyzing the data collected in steps one and two to identify the underlying cause of the problem. This may involve using tools such as the 5 Whys, Ishikawa diagrams, or Pareto charts.

The fifth section of the report should describe the countermeasures that have been developed to address the problem. This may involve brainstorming potential solutions and selecting the best course of action. It’s important to involve all stakeholders in this step to ensure buy-in and support for the chosen solution.

The sixth section of the report should describe how the countermeasures will be implemented. This may involve testing the solution on a small scale to ensure it’s effective before rolling it out more broadly. It’s important to document the implementation process to ensure that everyone involved is on the same page.

The seventh section of the report should evaluate the results of the countermeasures. This involves measuring progress against the target set in step three and determining whether the countermeasures have been effective. If the results are not satisfactory, it may be necessary to go back to step four and analyze the root cause again.

The final section of the report should describe how the solution will be standardized to ensure that the problem does not occur again in the future. This may involve creating a new standard operating procedure or updating an existing one. It’s important to communicate the new process to all stakeholders to ensure that everyone is on the same page.

In conclusion, generating an A3 Problem Solving report requires following the 8 steps of the A3 process. By providing a clear description of the problem, breaking it down into manageable parts, setting a target, analyzing the root cause, developing effective countermeasures, implementing those countermeasures, evaluating the results, and standardizing the solution, organizations can solve problems in a structured and effective way. By using the A3 report as a tool for communication, organizations can ensure that all stakeholders are on the same page and working towards a common goal.

Examples of successful A3 problem solving

A3 problem solving has proven to be effective across a diverse range of industries. In the following, you’ll find three instances of A3 Problem Solving reports that showcase its success.

Example 1: A3 Problem Solving reports for High Scrap Rate

Example 2: A3 Problem Solving reports for Late Deliveries

Example 3: A3 Problem Solving reports for Low Employee Morale

Common mistakes to avoid when implementing A3 problem solving

There are several common mistakes that organizations make when implementing A3 problem solving:

• Lack of clarity: Not having a clear problem statement can lead to wasted time and resources. It’s important to spend time defining and clarifying the problem at the beginning of the A3 process.
• Skipping steps: The A3 process is designed to be followed in a specific order, and skipping steps can lead to incomplete or ineffective solutions. It’s important to resist the urge to jump ahead and stick to the process.
• Rushing the process: A3 problem solving requires time and effort to be effective. Rushing through the process or trying to cut corners can lead to subpar solutions that don’t fully address the problem.
• Focusing on symptoms instead of root causes: It’s easy to address symptoms of a problem without addressing the underlying root causes. It’s important to take the time to identify and address root causes to prevent the problem from recurring.
• Lack of cross-functional involvement: A3 problem solving involves multiple departments and stakeholders, and not involving all relevant parties can lead to incomplete or biased solutions. It’s important to involve all necessary parties from the beginning of the process.
• Overcomplicating the process: A3 problem solving is meant to be a simple and straightforward process, and overcomplicating it can lead to confusion and frustration. It’s important to keep the process as simple and clear as possible.
• Ignoring feedback and results: A3 problem solving requires ongoing evaluation and feedback to determine the effectiveness of the solutions. Ignoring feedback or failing to measure results can lead to missed opportunities for improvement.
• Lack of standardization: A3 problem solving should be standardized across an organization to ensure consistency and effectiveness. Failing to standardize the process can lead to confusion and inconsistency in results.

A3 problem solving is a powerful tool that can help organizations improve their processes and products. The methodology is based on a structured problem-solving approach that involves identifying the problem, gathering data, analyzing the data, developing a solution, implementing the solution, and monitoring the results. A3 problem solving offers several benefits to organizations, including improved problem-solving skills, increased productivity, reduced costs, improved quality, and enhanced customer satisfaction. By following the A3 process closely and avoiding common mistakes, organizations can successfully implement A3 problem solving and achieve significant improvements in their operations.

A3 Problem Solving: Structured Approach to Solve Process Problems

Companies have various methods of solving problems. The effectiveness of a problem-solving approach influences the solutions achieved. A3 thinking is one way that businesses can come up with effective remedies for process challenges. 

Toyota developed A3 problem solving to facilitate collaboration, learning and personal growth amongst workers. The vehicle manufacturer is famous for its commitment to continuous improvement . Even with a large workforce, Toyota is always finding ways to boost performance. 

Through the A3 process, the manufacturer promoted in-depth problem-solving. Can the problem-solving template work for your enterprise, as well?

What is A3 Problem Solving

The A3 process is a structured problem solving and continuous-improvement lean methodology that reports issues then finds a way to solve them. It’s a structured approach that promotes continuous improvement . A3 refers to the paper size (European) the equivalent to the 11″x17″ (American), which is used to outline plans throughout the problem-solving process. 

A3 problem solving is similar to other problem-solving methodologies which all seem to be similar to Deming’s Plan-Do-Check-Act PDCA .

What is A3 thinking process?

A3 thinking is a team collaborative process and continuous improvement tool developed by Toyota

Toyota employs the A3 thinking process format in their Toyota lean manufacturing process in three areas: proposals, status and problem-solving. Taiichi Ōno from Toyota contributed to the popularity of the A3 template. Apparently, he preferred to have reported on a single page. As with other Lean systems, the A3 process focuses on visualisation. 

By outlining the problems that require solutions, it’s less complicated for employees to envision the results. Putting your process challenges on paper doesn’t guarantee that they will get fixed. However, the A3 planning principle makes a lot of difference.

A3 Problem Solving Process

How to Use an A3 Template. The A3 process requires you to understand the problem before devising solutions. The structured approach involves the following steps:

• Identify : Begin by identifying the challenges the background information. Different people can have varying views about the problem, and it’s crucial to learn this. The problem statement is developed at this stage.
• Summary : Next is a comprehensive summary of the current state. A proper understanding of the situation is necessary to find solutions.
• Goals : Come up with the goals or desired future statement. All stakeholders should agree on the objectives.
• Analysis : Conduct a root cause analysis to learn where the inefficiencies lie. The the 5 Whys and the Ishikawa Diagram ( Fishbone Diagram ) can help with this process.
• Solutions : Decide the countermeasures necessary to correct the situation. Short-term solutions might be necessary.
• Plan : Have a plan to implement the countermeasures. The plan should identify roles and a timeframe.
• Results : Check the outcomes to confirm if the executed solutions meet the objectives.
• Follow Up : The final stage should include follow-ups. Consider any actions that might improve the process and help maintain the positive results of the A3 exercise.

Benefits of A3 Problem Solving Process

With the correct implementation, businesses can get good value from the A3 structure. One is effective and quick problem-solving. The A3 process involves several steps that show you what to do at every point. Therefore, workers can approach problems through logical reasoning. Rather than jump straight to solutions, employees get to work through the stages.

The process boosts company growth. Businesses stagnate when they have to deal with the same issues over and over again due to poor problem-solving. An effective problem-solving method makes it easy to sustain good operating policies. The better a company can solve its challenges, the more it grows.

The objective thinking requires in the A3 process simplifies planning. Any great problem-solving approach involves a concrete blueprint. The stages of A3 thinking take the stress out of planning because you know what to do and when.

A3 thinking enhances collaboration across teams, thus promoting development. When employees have to use a structured tool repeatedly, it fosters knowledge sharing. The more people work together, the better they relate and learn to complement each other.

Companies can completely change how they see problems and deal with them through A3 thinking. However, implementing A3 problem solving is not enough. Organisations must know how to incorporate the tool into the existing Lean culture.

What is Six Sigma?

A great part of our daily work routine is actually related to solving problems. Either small or big, problems are an inevitable part of our workday. However, if you decide to act fast and remove a problem as swiftly as possible, you may face the same issue repeatedly.

Instead of fighting only the symptoms, you need to dig deeper and discover the root cause. By doing so, you will be able to protect the work process from recurring problems. This is where the A3 methodology comes into play.

Implementing an A3 problem-solving tool is a bright example of how problems should be treated to be eliminated efficiently. Based on some simple steps and ideas, the model gives directions on dealing with problem-solving issues through simple structuring, good collaboration, and active communication.

What Is A3 Thinking?

First of all, let’s briefly touch upon the mindset that A3 thinking aims to develop. It can be summarized in 7 elements:

• Logical Thinking – A3 represents a step-based thinking process.
• Objectively presenting information – there are no hidden agendas here.
• Results and Processes – sharing what end results were achieved as well as the means of achieving them.
• Sharing only essential information and putting it into a visual format whenever possible.
• Whatever actions are taken, they must be aligned with the company’s strategy and objectives.
• The focus is on developing a consistent perspective that can be adapted across the entire organization.
• Developing a structured approach to problem-solving.

Origin of the A3 Problem-Solving Tool

The A3 report is one of the many Lean management tools developed as part of the Toyota Production System (TPS).

There isn’t a single inventor of the A3 reporting method. In fact, Isao Kato (former manager at Toyota) describes it as a hybrid between the PDCA cycle and Toyota’s philosophy to make things visible.

There is also a legend that Taiichi Ohno often refused to read further than the first page of any written report. This is why the A3 is a one-page report.

The name A3 comes from the European A3 paper size corresponding to 11-inches by 17-inches or 29.7cm x 42cm.

A3 thinking played a major role in Toyota’s commercial success. Consequently, it became a widespread tool, now used in various industries.

Let’s explore the A3 problem-solving tool in detail.

Foundations of the A3 model

Actually, A3 is just a single report that will not help you solve problems like a magic wand. It is much more important for all involved parties to be dedicated to the process and communicate actively.

Before you begin with the formation of your own A3 reporting method, you need to be familiar that there are 3 major roles in the process:

• Mentor/coach

The owner is responsible for managing the process and maintaining the document. On the other hand, the owner needs to be advised and supervised by a mentor experienced in problem-solving.

The mentor’s role is to give directions and provoke the problem owner to find the solution, but not to give answers and propositions.

Last but not least, there are responders or stakeholders. They are the third party, which is directly interested in the final results of the A3 project.

Here is the challenge. Usually, there is a wide variety of stakeholders involved. The problem owner needs to have access to all of them if needed.

However, we all know that it is a bit difficult to reach higher management in organizations with a strict hierarchy.

This is why the whole organization should be familiar with the concept of lean thinking and be prepared to assists at any time. Sometimes this is challenging, but it can show how flexible an organization really is.

At the end of the day, the active communication between all parties involved is crucial for the success of any A3 project.

The A3 Report

The A3 report is a single-page document, which reflects the results of the whole process. Usually, it contains seven steps, but it may also have other variations. Below you can find an A3 report example, which most often will include the following steps:

• Background/Clarify the problem

Current situation

Set targets/goals, root cause analysis, countermeasures.

• Implementation
• Effect confirmation/Follow-up

The A3 Process

The A3 methodology is a lean thinking process where the problem owner should go through the model's different steps until there is a proper solution to be implemented. The owner needs to communicate actively with his colleagues and the mentor of the project.

Let’s now examine the different steps that comprise the A3 process.

First of all, you need to clarify the problem and briefly describe it. This is a starting point where the owner can add context and support the next steps.

Before a problem can be addressed properly, the problem owner needs to describe the current situation in the area where the issue appears.

At this stage, you can map the different processes that exist around the problem area. It will allow you to see the bigger picture and identify the root cause.

After the current situation is clear, you need to set goals. Keep in mind that at this stage, you need to take into consideration that you don’t have  the full picture .

So after you go through the remaining steps until “effect confirmation,” you can come back to this step and add more details to the initial goals.

This is a significant step from the successful implementation of the A3 process. Trying to fight the problem immediately means that you are only treating the symptoms while leaving the root cause untouched. This way, a problem may appear regularly in bigger proportions.

Therefore, once you have a good understanding of how the processes work and the initial goal, you need to figure out the root cause of the problem. For this purpose, you can use different techniques such as  the 5 whys .

Once you are familiar with the root cause, you may start offering solutions. From here, you can go back to the initial goal and add more details. In all cases, the countermeasures should lead to a clear understanding of how the initial goal will be achieved.

Implementation Plan

After setting the countermeasures, you have to present an implementation plan that includes a list of the actions that will be applied to get the countermeasures in place. It is also helpful to assign responsible individuals for each task and a due date.

Effect confirmation & Follow-up

The last step is crucial for establishing a culture of continuous improvement . It is imperative to measure the actual results and confirm the effect of your countermeasures.

Whether there are positive or negative results, you need to take action.

If the actual results differ from the predicted ones, you should modify the plan, re-implement it, and follow up.

If there is a positive effect, you should communicate improvements to the rest of the organization and ultimately make them a standard.

Benefits of A3 Problem-Solving

The A3 model is consistent, and it encourages mentoring and overall collaboration.

Furthermore, it promotes the cross-organizational sharing of information and encourages learning and continuous improvement on every organizational level.

Also, the A3 methodology encourages commitment to common goals and strengthens the levels of responsibility.

Last but not least, you can use an A3 report not only for problem-solving but also for proposing improvements, reporting, coaching, and others.

The A3 Thinking Problem Solving Approach: A Better Way To Solve Team Problems

The A3 thinking problem solving approach is a lean based, structured approach to problem solving. It has seven distinct stages: problem statement, current state, future goal, root cause, immediate solution, long term solution and action plan. Summary by The World of Work Project

The A3 Thinking Problem Solving Approach

There are many different approaches to problem solving. The A3 Thinking Problem Solving Approach is one of the most helpful. It was developed by Toyota and fits well with their approach to management.

This seven step model ensures you focus first on fully understanding the wider situation, where you would like to end up, and the root-causes of your problem before thinking about solutions.

The belief underlying the model is that it is much better to address the real root-cause of the problem than to try and overcome it in any other way. To help make sure you do this, the model is divided into two halves. The first (stages 1-4) focuses on developing understanding, and the second (stages 5-7) focuses on developing a solution.

It’s essential that you don’t jump to solutions when solving problems or working to address opportunities. Whenever you choose a solution too quickly, you close down a myriad of other options that could be far better. You also close down conversations about what the current situation is like and why things are the way they are. These conversations can broaden knowledge and be the base for much more informed and creative solutions. So in short, follow the steps in order and don’t jump to solutions!

The A3 Thinking model can be completed in one problem solving session of about 60-90 minutes when problems are simple. However, when they are complicated you may require two, three or even four sessions of that length to complete the process.

Stage 1: What is the Problem? Why is it Worth Spending Time on?

The first stage of the A3 thinking problem solving approach is to define the problem.

The purpose of this stage is to agree a problem statement. Often each person involved in problem solving starts with a different understanding of what the problem is.

In this stage you go around the attendees and ask each one to define the problem. Capture definitions as you go. Once everyone has spoken, pull the problem statements together until you have a single statement the room agrees on.

You may need to return to this stage several times as you progress through the A3 process.

Stage 2: What is the Current State?

The purpose of this stage is to document the current state of the problem and the factors that influence it. You could document your discussions in this stage as a list of bullet points, through diagrams, through process flows, though paragraphs, or whatever you think best. Whatever approach you use, try and ensure a fairly comprehensive summary of the current situation.

Asking questions of the room can be hugely helpful in this section. Questions to consider could include: What happens next? Who’s involved? Where is it? When does it happen? Who inputs? How many failures are there? And whatever other questions you think will help draw out the what is happening in the current state.

Stage 3: Desired Future State

The third stage of the A3 thinking problem solving approach is to define the desired future state.

Having captured an informed view of the current state of the problem, the next step is to capture an informed view of what a good future state would look like. This should be simple and high level. It could be just a sentence or two long. It’s important that the attendees are agreed on it. They should also feel it addresses the challenges raised in the problem statement.

It’s often advisable to re-validate your problem statement at this stage. In many situations, a deeper understanding of the current situation and the act of framing a future state leads participants to re-assess what the problem actually is.

Stage 4: Root Cause Analysis

Having understood what the problem is, what the current situation is and what would constitute a good future, it’s time to really dig into the problem and understand why it’s happening. This is the most important part of the A3 thinking process. Two tools most commonly used to support this process are the “ 5 Whys ” and “ Fishbone Analysis “.

Silent Brainstorming

Start the process by having all attendees silently brainstorm why the problem is happening. What do they think the root causes of the problem are. They should capture each root cause on a separate post it note. For each root case they think of, they should challenge it further. To do this they should use the 5 Whys approach (basically, just keep asking why).

Sort and Group

Once all attendees have finished their silent brainstorming, the next stage is to discuss and thematically group all of the identified root causes. One attendee starts the process by reading out one of their root causes and placing it on a wall. The facilitator then asks if anyone else in the room has something similar. Once all the similar post its are placed, begin again with another person reading out a different root cause. The process continues until all root causes have been considered and grouped.

As this stage, the root causes are considered and their grouping assessed. If the room is happy with the grouping, the next activity is to give a name to each of the categories of root causes that have been created. These names might be as high level as “People” or “Systems”. We would expect there to be in the order of 4-8 high level groups of this nature. This grouping exercise can be captured in a “fish-bone template” (AKA Ishikawa template) for later reference.

Understanding and documenting root causes of the problem is the last stage in the first half of the A3 process. Remember, this is the half that focuses on broadening understanding of the problem.

Once this has been completed and everyone has a better understanding of the problem, it’s time to move on to trying to find a solution.

Stage 5: Short Term Solution

The fifth stage of the A3 thinking problem solving approach is to find any needed short term solutions.

The first step in looking for a solution focuses on solving any urgent issues. If the problem you are working on has resulted in critical operational issues, then you’ll need to develop a short term fix to manage them until you can implement a longer term solution. In many instances though, it’s possible to skip this stage and move directly to stage 6.

If you do need to focus on a short term solution then the participants in the room should work towards that now. Individuals should propose and discuss temporary measures to overcome the problem and the room should consider them to ensure they meet requirements. Their cost and difficulty should also be assessed before the room decides on which one to implement as a short term, immediate fix.

Stage 6: Long Term Solution

Even if you are implementing a short-term solution to your problem, it’s important to focus on and create a lasting, long-term solution to all problems.

Usually long term solutions will include a range of activities designed to permanently address the different root causes that have been identified. They will typically require a portfolio of activities to ensure that they are comprehensive and sustainable.

In this part of the conversation the participants in the room should propose and discuss longer term solutions. You may wish to ask the participants to think about each of the high level root-cause groups that have been identified. It may be your longer term solution is really a combination of solutions to those higher level root-causes.

Whatever process you adopt here, it’s important to compare your proposed solution or portfolio of solutions to your fish-bone diagram to ensure that the solution addresses all of the identified root causes (or at least enough of them that the problem no longer exists).

Stage 7: Action Plan

The last stage of the A3 thinking problem solving approach is to plan actions.

This stage is all about translating the solution into a step by step action plan. It’s only once you’ve broken the proposed solution down into the steps required to create it that you have a real pathway toward implementing it.

At this stage the participants should consider the various aspects of the proposed solution and determine the schedule of actions required to implement them. These actions should be sequenced, they should have due-dates assigned to them and each one should also have an owners assigned to it. In short, a project plan should be created to help govern the implementation of the proposed solution.

Implementing Your Plan

Once you’ve completed your plan it might feel like you’ve nearly solved your problem, but you’re only really at the starting line! The process of delivering on your action plan is hugely important to the actual addressing of your problem.

To ensure you actually implement your solution, you should assign an overall project manager. This may simply be a named person in your team. They should be responsible for ensuring that the individuals who were identified as action owners in stage 7 of the A3 thinking model progress their actions in line with their target dates. To further ensure that the solution is implemented, you should hold weekly problem solving meetings at which you reflect on progress.

One of the most important things to remember when looking to implement a solution like this is time. People need to have time set aside and free of other work to focus on their actions. If they don’t, then your problems won’t get solved.

Learning More

Thinking about what we do from different perspectives and with others is very helpful for decision making. Tools like the reframing matrix process or hackathons can help us do this.

Part of the reason we’re not great at problem solving is that we all have thinking habits and cognitive biases that restrict our creativity. In particular, these decision making biases often lead us towards bad (or irrational) decisions. And sometimes we make decisions just because ISLAGIATT …

Similarly, Drilling into issues with the 5 Whys helps us understand root causes more and creating an ease/benefit matrix helps us decide what to focus on in the first place. When we are actually working on things like this in groups it’s useful to use techniques like silent brainstorming to get the best results.

To learn more about creativity, innovation and problem solving, you might enjoy the third of our three podcasts specifically on these topics. It focuses mainly on cognitive processes:

The World of Work Project View

A huge amount of time and effort is spent ineffectively trying to solve problems within organizations. There are many different reasons for this, but one of the causes is that people don’t know how to solve problems well. This is something the A3 Thinking approach can help overcome.

Based on our experience, we think that this model is effective for a wide range of problems, provided it’s used well. To be used well it usually requires a dedicated facilitator, and it can be helpful if they are experienced.

It’s very possible though to over-complicate the approach to problem solving. While this model is great for use with more complex problems, there are many, simpler problems which should be solved without using it.

How to use Toyota’s legendary A3 problem-solving technique

Georgina Guthrie

February 21, 2020

If you came home one day and found your kitchen taps on full-blast and your house full of water, what’s the first thing you’d do? Grab a bucket and start scooping — or turn off the tap?

When it comes to problem-solving, many of us take a rushed, reactionary approach rather than fixing the issue at the source. So in other words, we see the water, panic, and start scooping. If this sounds like something you’ve done recently, then don’t feel too bad: when the pressure’s high, we often jump towards the quickest fix, as opposed to the most effective one.

This is where the A3 technique comes in. It’s a problem-solving approach designed to efficiently address the root cause of issues.

What is the A3 technique?

The A3 technique is a structured way to solve problems. It’s part of the Lean methodology  developed by Toyota back in the mid-’40s. This doesn’t mean you need to implement a Lean way of working to take advantage of this process — it can work as a standalone exercise.

Granted, A3 isn’t an inspiring name, but the story of its origins is actually pretty interesting. Rumour has it that Taiichi Ohno, inventor of the Toyota Production System, refused to read past the first page of any report. In response, his team created A3 to address and summarize problem-solving on one side of A3-sized paper. The A3 technique played a huge part in Toyota’s success and all kinds of industries have since adopted it. Here’s how to get started.

How to solve a problem with A3

The first thing to remember is this: A3 is collaborative and relies on good communication. It’s not something you should do by yourself.

There are three main roles involved:

• Owner (that’s you or someone under your charge)

As you’ve probably guessed, these aren’t roles that already exist in your company; you must create them for the purpose of this process. Here’s what they mean.

The owner is responsible for leading the exercise. They are the lynchpin between the two other roles, fostering good communication and keeping documents up to date. It’s tempting to think of the owner as the head of this trio, but that’s not true: everyone is equal here.

The mentor is someone with solid  problem-solving experience. Their job is to coach the owner and steer them toward finding a solution; it’s not their job to find the answers themselves.

And finally, there are the  responders . This is someone (or a group of people) who has a vested interest in the outcome of the A3 project. Responders might include the client, stakeholders, or managers. A potential problem here is gaining access to them: if you work somewhere with a strict hierarchy — and you’re somewhere near the bottom of that structure — you may face challenges. There’s no easy way around this. Essentially, you need your organization to support this way of working and make it easy for you to access those at the top if needed.

How to create an A3 report

True to its origins, the A3 report is a one-page document. It typically contains 5-7 sections that systematically lead you towards a solution. These are the most commonly used steps but feel free to modify them.

• Background:  Explain your project in a few sentences, including its context.
• Problem statement:  Explain the current problem. You can use process mapping to see the different tasks that surround the issue. This isn’t essential, but it will make it easier for you to locate the root cause.
• Goals: Define your desired outcome and include metrics for measuring success. You won’t know everything until you reach the end, so you may need to revisit and refine stages 1-3.
• Root cause analysis:  This is a big stage of the process. You need to work out what you think the root problem is. You can use different methods to help you here, including 5 whys or a fault tree analysis .
• Countermeasures:  Once you’ve worked out your root cause, you can start proposing solutions.
• Implementation:   Plan how you’ll implement these solutions, including an action list with clearly defined roles and responsibilities.  Project management software is useful here because it allows the team to track each other’s progress in real time .
• Follow-up: Using your metrics for success, decide whether the problem was solved. Report your results back to the team/organization. In the spirit of Lean (continuous improvement), you should go back and modify your plan if the results aren’t as expected. And if they were, you should make this process the new standard.

Problem-solving tools

A3 is an efficient, methodical way to solve problems at their source. When issues rear their head, rising stress can lead people to panic. Having a clearly designed system in place to guide you towards a solution minimizes the chances of people settling for a ‘quick fix’ or failing to act altogether.

Beyond being a guiding light in times of pressure, A3 is a great team-building exercise because it encourages individuals to work together towards a common goal — across all areas of the organization. Combine this with collaborative tools designed to help teams track progress and work together more effectively, and you’ll be unstoppable.

How to A3: Resources for Developing Structured Problem-Solving and Leadership Skills

June 18, 2020

As LEI prepares its next course on Managing to Learn, here's a popular article rounding up a wealth of resources about practicing A3 Thinking by Tom Ehrenfeld

A3 reports have become one of the most popular lean tools today, a way for people and teams to work together to solve problems; and their widespread adoption could easily be viewed in lean terms as…a problem.

Tools often provide traction for getting started with lean practice, and A3s often deliver immediate results. The A3 ‘problem’ (a gap, in this case, between the intended purpose and actual usage) echoes the broader challenge facing widespread adoption of any proven TPS methodology: moving from lean tools to lean management , according to Jim Womack. As he notes, “Tools—for process analysis and for management—are wonderful things. And they are absolutely necessary. And managers love them because they seem to provide shortcuts to doing a better job. But they can’t achieve their potential results, and often can’t achieve any results, without managers with a lean state of mind to wield them.”

Let’s keep in mind the purpose of A3s, from the Introduction to John Shook’s key book on the topic, Managing to Learn   ( MtL ).

“Writing an A3 is the first step toward learning to use the A3 process, toward learning to learn. Some benefits in improved problem-solving, decision-making, and communications ability can be expected when individual A3 authors adopt this approach.”

All well and good. Unfortunately most organizations stop there, and don’t proceed to the next step. As Shook cautions, “unless the broader organization embraces the broader process, the much greater benefit will be unrealized. The entire effort may degenerate into a ‘check-the-box’ exercise, as A3s will join unused SPC charts, ignored standardized work forms, and disregarded value-stream maps as corporate wallpaper.”

So what exactly are A3 reports? A3 reports are a way of structuring and sharing knowledge that enables teams and their members to practice scientific thinking as a way of discovering and learning together. The tool promises immediate benefits by helping people structure and design more effective approaches to problems (framing them in solvable ways, taking a data-based approach, using root-cause-analysis to find the point of origin for problems (gaps), encouraging careful problem analysis over quick abstract “solutions,” and so forth).

Definitions include:

• A storyboard
• 5S for information
• Standardized story-telling
• A “visual manifestation of a problem-solving thought process involving continual dialogue between the owner of an issue and others in an organization.”

They are all that, and more. Essentially, A3 reports, named for the international-sized A3 paper (a larger page of roughly 11 by 17 inches), enable people in organizations to capture issues through a commonly understood template, permitting people to see problems through the same lens. The sequence is designed along the logic of scientific thinking—the PDCA cycle at the heart of lean thinking. You can download A3 templates from LEI here .

The basic thinking process captured by this format is relatively simple, and has been around in many other forms and formats for a long time. There are different types of A3s , according to the situation. But don’t work too hard to find the precisely right format; in fact, veterans such as David Verble stress the importance of starting your A3 not by writing but by thinking .

“The most fundamental use of the A3 is as a simple problem-solving tool. But the underlying principles and practices can be applied in any organizational setting. Given that the first use of the A3 as a tool is to standardize a methodology to understand and respond to problems, A3s encourage root cause analysis, reveal processes, and represent goals and actions in a format that triggers conversation and learning,” says John Shook in this piece sharing his purpose for writing MtL .

There’s no doubt that those with deep experience have found great power in A3 practice. For example, lean veteran Gary Convis says that he, “used the A3 format as a way of seeing inside the minds of the 113 plant managers,” citing his experience at Dana Holdings Corp , as well as elaborating on using A3 problem solving to make the thinking process visible .

Toyota veteran Tracey Richardson shares a hugely practical step-by-step tour of the A3 thinking process in her great article Create a Real A3, Do More than Fill In Boxes . In so doing she explains how an A3 is “a way of thinking with deeper benefits, a process based on the PDCA (plan, do, check, adjust) cycle designed to “share wisdom” with the rest of the organization.” Another terrific A3 “stroll” is provided in this recent piece by Jon Miller .

Tracey complements her brief user’s guide with a piece that suggests you Test Your PDCA Thinking By Reading Your A3 Backwards as a way of avoiding a common A3 hazard—jumping to conclusions.

When given a problem to solve, most individuals rush to provide the bestest solution the fastest. Yet the nature of A3 thinking requires careful framing of the problem, rigorous analysis of a clearly defined (and improvable “gap”), patient observation at the source, and real dialogue with the people touching the problem.

The A3 form exists to capture and document this material; it is not a formal document in and of itself. “If you’re ‘doing’ or ‘filling out’ an A3 behind your desk, I can say most of the time you will not be able to answer the questions above [listing the cause and effect logic of an A3],” says Tracey.

It’s worth noting that while there are different types of A3 reports, it’s useful to recognize that “not every situation requires an A3,” according to Norbert Majerus of Goodyear. In  To A3 or Not to A3 , he proposes a situational application that avoids a one-size-fits-all tool mindset. Specifically, he explains how the cynefin framework developed by Dave Snowden and Mary Boone can help navigate the different situations in one might apply A3 thinking.

Some argue that good problem-solving is not about having the right answers; it’s about practicing a useful, and commonly understood approach to thinking about thinking (learning). “Never lose sight of the thinking process that enables you to complete an A3—which then serves as a way of capturing, communicating, and building on what was learned,” says Tracey in A3: Tool or Process? Both…

In deepening this thinking-process through “A3 Mind,” you and your teammates can learn to activate what Daniel Kahneman calls both “fast” and “slow” thinking, says Michael Balle. “The key is to look at A3s as a physical support for managerial relationships based on expertise and teaching,” as a way to sustain A3 thinking in your organization , he notes. Such a shared approach can bring about a core lean goal: helping a problem-solving culture take root .

Problem Solving Methodologies

Individuals and organisations can use a variety of problem-solving methodologies to address complex challenges. 8D and A3 problem solving techniques are two popular methodologies in the Lean Six Sigma framework.

Methodology of 8D (Eight Discipline) Problem Solving:

The 8D problem solving methodology is a systematic, team-based approach to problem solving. It is a method that guides a team through eight distinct steps to solve a problem in a systematic and comprehensive manner.

The 8D process consists of the following steps:

• Form a team: Assemble a group of people who have the necessary expertise to work on the problem.
• Define the issue: Clearly identify and define the problem, including the root cause and the customer impact.
• Create a temporary containment plan: Put in place a plan to lessen the impact of the problem until a permanent solution can be found.
• Identify the root cause: To identify the underlying causes of the problem, use root cause analysis techniques such as Fishbone diagrams and Pareto charts.
• Create and test long-term corrective actions: Create and test a long-term solution to eliminate the root cause of the problem.
• Implement and validate the permanent solution: Implement and validate the permanent solution’s effectiveness.
• Prevent recurrence: Put in place measures to keep the problem from recurring.
• Recognize and reward the team: Recognize and reward the team for its efforts.

A3 Problem Solving Method:

The A3 problem solving technique is a visual, team-based problem-solving approach that is frequently used in Lean Six Sigma projects. The A3 report is a one-page document that clearly and concisely outlines the problem, root cause analysis, and proposed solution.

The A3 problem-solving procedure consists of the following steps:

• Determine the issue: Define the issue clearly, including its impact on the customer.
• Perform root cause analysis: Identify the underlying causes of the problem using root cause analysis techniques.
• Create and implement a solution: Create and implement a solution that addresses the problem’s root cause.
• Monitor and improve the solution: Keep an eye on the solution’s effectiveness and make any necessary changes.

Subsequently, in the Lean Six Sigma framework, the 8D and A3 problem solving methodologies are two popular approaches to problem solving. Both methodologies provide a structured, team-based problem-solving approach that guides individuals through a comprehensive and systematic process of identifying, analysing, and resolving problems in an effective and efficient manner.

Step 1 – Define the Problem

The definition of the problem is the first step in effective problem solving. This may appear to be a simple task, but it is actually quite difficult. This is because problems are frequently complex and multi-layered, making it easy to confuse symptoms with the underlying cause. To avoid this pitfall, it is critical to thoroughly understand the problem.

To begin, ask yourself some clarifying questions:

• What exactly is the issue?
• What are the problem’s symptoms or consequences?
• Who or what is impacted by the issue?
• When and where does the issue arise?

Answering these questions will assist you in determining the scope of the problem. However, simply describing the problem is not always sufficient; you must also identify the root cause. The root cause is the underlying cause of the problem and is usually the key to resolving it permanently.

Try asking “why” questions to find the root cause:

• What causes the problem?
• Why does it continue?
• Why does it have the effects that it does?

By repeatedly asking “ why ,” you’ll eventually get to the bottom of the problem. This is an important step in the problem-solving process because it ensures that you’re dealing with the root cause rather than just the symptoms.

Once you have a firm grasp on the issue, it is time to divide it into smaller, more manageable chunks. This makes tackling the problem easier and reduces the risk of becoming overwhelmed. For example, if you’re attempting to solve a complex business problem, you might divide it into smaller components like market research, product development, and sales strategies.

To summarise step 1, defining the problem is an important first step in effective problem-solving. You will be able to identify the root cause and break it down into manageable parts if you take the time to thoroughly understand the problem. This will prepare you for the next step in the problem-solving process, which is gathering information and brainstorming ideas.

Step 2 – Gather Information and Brainstorm Ideas

Gathering information and brainstorming ideas is the next step in effective problem solving. This entails researching the problem and relevant information, collaborating with others, and coming up with a variety of potential solutions. This increases your chances of finding the best solution to the problem.

Begin by researching the problem and relevant information. This could include reading articles, conducting surveys, or consulting with experts. The goal is to collect as much information as possible in order to better understand the problem and possible solutions.

Next, work with others to gather a variety of perspectives. Brainstorming with others can be an excellent way to come up with new and creative ideas. Encourage everyone to share their thoughts and ideas when working in a group, and make an effort to actively listen to what others have to say. Be open to new and unconventional ideas and resist the urge to dismiss them too quickly.

Finally, use brainstorming to generate a wide range of potential solutions. This is the place where you can let your imagination run wild. At this stage, don’t worry about the feasibility or practicality of the solutions; instead, focus on generating as many ideas as possible. Write down everything that comes to mind, no matter how ridiculous or unusual it may appear. This can be done individually or in groups.

Once you’ve compiled a list of potential solutions, it’s time to assess them and select the best one. This is the next step in the problem-solving process, which we’ll go over in greater detail in the following section.

Step 3 – Evaluate Options and Choose the Best Solution

Once you’ve compiled a list of potential solutions, it’s time to assess them and select the best one. This is the third step in effective problem solving, and it entails weighing the advantages and disadvantages of each solution, considering their feasibility and practicability, and selecting the solution that is most likely to solve the problem effectively.

To begin, weigh the advantages and disadvantages of each solution. This will assist you in determining the potential outcomes of each solution and deciding which is the best option. For example, a quick and easy solution may not be the most effective in the long run, whereas a more complex and time-consuming solution may be more effective in solving the problem in the long run.

Consider each solution’s feasibility and practicability. Consider the following:

• Can the solution be implemented within the available resources, time, and budget?
• What are the possible barriers to implementing the solution?
• Is the solution feasible in today’s political, economic, and social environment?

You’ll be able to tell which solutions are likely to succeed and which aren’t by assessing their feasibility and practicability.

Finally, choose the solution that is most likely to effectively solve the problem. This solution should be based on the criteria you’ve established, such as the advantages and disadvantages of each solution, their feasibility and practicability, and your overall goals.

It is critical to remember that there is no one-size-fits-all solution to problems. What is effective for one person or situation may not be effective for another. This is why it is critical to consider a wide range of solutions and evaluate each one based on its ability to effectively solve the problem.

Step 4 – Implement and Monitor the Solution

When you’ve decided on the best solution, it’s time to put it into action. The fourth and final step in effective problem solving is to put the solution into action, monitor its progress, and make any necessary adjustments.

To begin, implement the solution. This may entail delegating tasks, developing a strategy, and allocating resources. Ascertain that everyone involved understands their role and responsibilities in the solution’s implementation.

Next, keep an eye on the solution’s progress. This may entail scheduling regular check-ins, tracking metrics, and soliciting feedback from others. You will be able to identify any potential roadblocks and make any necessary adjustments in a timely manner if you monitor the progress of the solution.

Finally, make any necessary modifications to the solution. This could entail changing the solution, altering the plan of action, or delegating different tasks. Be willing to make changes if they will improve the solution or help it solve the problem more effectively.

It’s important to remember that problem solving is an iterative process, and there may be times when you need to start from scratch. This is especially true if the initial solution does not effectively solve the problem. In these situations, it’s critical to be adaptable and flexible and to keep trying new solutions until you find the one that works best.

To summarise, effective problem solving is a critical skill that can assist individuals and organisations in overcoming challenges and achieving their objectives. Effective problem solving consists of four key steps: defining the problem, generating potential solutions, evaluating alternatives and selecting the best solution, and implementing the solution.

You can increase your chances of success in problem solving by following these steps and considering factors such as the pros and cons of each solution, their feasibility and practicability, and making any necessary adjustments. Furthermore, keep in mind that problem solving is an iterative process, and there may be times when you need to go back to the beginning and restart. Maintain your adaptability and try new solutions until you find the one that works best for you.
