A3: Thinking, Reports, Examples & Templates

A3 thinking, an introduction to a3.

In the design and construction industry – as in all industries – complex problems arise daily. Each project contains hundreds of decisions containing thousands of variables, and sorting them out to arrive at the best outcome is critical.

A3 problem solving provides teams with a strategy to effectively and efficiently deal with problems that they encounter and decisions that need to be reached. In true Lean fashion, A3 process improvement brings the entire team into the collaborative problem-solving process and allows teams to embrace out-of-the-box solutions.

What is A3?

An A3 is a one-page report prepared on a single 11 x 17 sheet of paper that adheres to the discipline of PDCA thinking as applied to collaborative problem solving, strategy development or reporting. The A3 includes the background, problem statement, analysis, proposed actions, and the expected results.

The History

A3 thinking was developed by Toyota in the 1940s. Toyota believed that any problem should be capable of being explained and solved using one sheet of paper (an 11 x 17 sheet being the largest sized paper that is capable of being faxed and closest in size to the traditional A3). 

The company also believed that if a problem is too complex to fit onto an A3 report, it should be broken down into smaller bits that would be solved individually. If your problem cannot fit onto an A3, you should reconsider the scope of what you are hoping to accomplish.

Who Uses A3 Strategies?

Today, A3 strategies are deployed across various industries that employ Lean thinking such as:

• Design & Construction
• Manufacturing
• Project Management
• Engineering & Architecture
• Service Industries

LCI’s Meaning of A3

A3 thinking is an extremely useful tool when utilized correctly. By distilling the entirety of a problem on a single sheet of paper, A3 Lean thinking forces team members to collaborate and rationalize through the problem solving process. A3 thinking makes for more effective problem solving and produces written explanations that can then be passed on to senior management. An effectively completed A3 report will also build management’s confidence in the team and its ability to solve problems.

A3 Reporting

A well-written A3 report should show and explain the consideration that went into the counter-measure to the problem listed. Properly executed plans include the input of team members from all across the stakeholder spectrum and should allow members to emerge as leaders in its problem solving. A3 papers can also be referenced later, allowing the lessons learned during the process to be shared with future project teams.

Understanding A3 Thinking

A3 thinking does not provide a solution to the problem your team is facing. Rather, it guides your team’s process to help it reach the best possible countermeasure with the tools it has at its disposal.

An A3 report is to be filled out by one person on the team – the “champion” – who will gather assessments and intel from other members in a collaborative fashion. Bringing all of the knowledge and expertise of the team to bear when solving a problem is the best way to come to a satisfying outcome.

Problem Solving: An A3 Process

A3 thinking allows for many different types of decision-making. But ultimately, all decisions are fundamentally a form of problem solving. For example, A3 thinking can be deployed to guide the team in optimizing decisions during the design phase, or for solving a constructability challenge.

The First Step to A3 Thinking

The first step of the A3 process for problem solving is to correctly identify the problem. From unexpected lead times on materials to communication breakdowns among design teams, “problems” are in no short supply in the design and construction industry. Before engaging in A3, ask yourself the following questions about the problem you are working to solve.

Questions to Facilitate the Process

• What are you trying to address or solve?
• What is the current situation?
• What are clear Conditions of Satisfaction (CoS) I can develop?
• Where can I brainstorm and analyze the 5 whys/root cause ideas?
• What’s a recommendation I can put forth?
• What is my plan to implement the recommendation above (if applicable)?

State plan to check and adjust using the PDCA cycle.

More on the PDCA Cycle

PDCA stands for Plan, Do, Check, Adjust. Explore each element of this acronym for more information about how it supports both the problem solving questions above as well as A3 problem solving as a whole.

Identify an issue in your process and exercise continuous improvement by planning your course of change.

Perform your case study by applying the corrective actions outlined in the “plan” stage in an experimental manner.

Follow the performance of your experiment and measure it to determine whether it is having the desired effect.

If your plan worked, implement the change to the necessary areas of your process. If it did not, determine what you will do differently next time and repeat the cycle.

A3 Reports for Solutions

While A3 reports broadly follow the PDCA cycle, the actual journey of an A3 process is a bit more granular. Let’s analyze the various steps and sections of an A3 report.

Describe the problem, theme, or issue. List out all of the details including the champion’s name, date, and the names of all of the collaborators who will be helping with the report.

Establish the business context & importance. Provide additional information on the problem being addressed.

Current State

Describe what is currently known about the problem. Note potential variables and roadblocks that may stop your team from solving this problem and additional information you hope you acquire.

Future State or Goal

Identify the desired outcome for your experiment. Identify the Conditions of Satisfaction (CoS) for the project.

Analyze the situation and underlying cause.

Recommendation

Provide a recommendation for process improvement that your team can implement for the future.

Create a follow-up/review process.

A3 Examples

A3 thinking is frequently applied in Lean design and Lean construction during all phases of the process for the purposes of making sound decisions. In the example below, A3 thinking is applied to the process of learning Lean design and construction techniques.

Problem-solving is one of the key tools a successful business needs to structure improvements and one I have been using to solve problems in a structured way in my career are Continental AG and other businesses over the years. When there is a problem in business that is leading to increased costs, waste , quality issues, etc., it is necessary to address these problems. A3 structured problem solving is a Lean Six Sigma methodology that has been designed and developed to support continuous improvement and solve complex business problems in a logical and structured process. 

The guide will give you a full understanding of what A3 Problem solving is and a breakdown of all the steps of how to apply it within your business with an example of where I have made improvements with it previously.

Importance of a3 in lean management.

The A3 problem-solving method is a key tool in Lean Six Sigma and continuous improvement in business, and in my experience, it is often the standard approach all improvement activities must follow and is particularly popular in the automotive industry. This is because of the following:

Focus on Root Causes : Rather than applying a quick fix to a problem or jumping to conclusions and solutionizing, A3 requires gaining a deep understanding of the root causes of the problem. By addressing these root causes, the chances of recurrence is reduced.

Standardization : With a consistent format, the A3 process ensures that problems are approached in a standardized way, regardless of the team or department. This standardization creates a common language and understanding across the organization and ensures all problems are addressed to the same standard and approach.

Team Involvement : An A3 isn’t an individual process. It requires a cross-functional team to work together on problem-solving, ensuring that a range of perspectives and expertise is considered. This collective approach builds a stronger understanding of the problem and ensures that solutions are well-rounded and robust.

Visual Storytelling : The A3 report serves as a visual storyboard, making it easier for stakeholders at all levels to understand the problem, the analysis, and the countermeasures. This visualization enhances communication and drives alignment.

The 6 Steps of A3 Problem Solving (With Real Example)

The A3 problem-solving process can initially seem difficult if you have never done one before and particularly if you have never been a team member in one. To help you with this we will break down the 6 steps into manageable activities, followed by a real-life example to help you apply this method within your business.

As a side note, the A3 problem-solving process was actually one of the first Lean Six Sigma tools I learned to use three weeks into my continuous improvement career after being thrown into the deep end due to resource availability, so I can understand how difficult it can be to understand. 

Step 1: Describe the problem

Problem description.

The problem description is an important first step in the process as it ensures a common understanding with the team of what the issue is that needs to be addressed. This can be done by using a technique called the 5W1H Is/Is Not method to help gain a clear understanding of the problem. 

To understand the 5W1H Is/Is Not the Process, check out our guide for details of that technique. However, in short, it’s about asking key questions about the problem, for example, “What IS the problem?” and “What IS NOT the problem?”

Let’s say you have been asked to look into a problem where “Machine downtime on the automotive assembly line has increased by 30% over the past three months, leading to production delays and increased costs.”

An example of a 5W1H Is/Is Not on this may result in the following output:

 Based on this we can create a clear problem description as the focus of the project that give the team a clear and common understanding of the issue looking to be resolved in the next steps of the process. The problem description could then be written as:

“Over the past three months, machine downtime on Automotive Assembly Line No.3 has increased by 30%. This has predominantly affected the assembly line workers and leads, leading to production delays and higher labor costs. “

Current Condition

Next is demonstrating the current condition and demonstrating the impact on the business. This can often be done with data and charts to back up the problem that might show trends or changes in outputs.

This might look something like the below and demonstrate a good baseline for confirming the improvement at the end of the A3

Containment Actions

Next is containment actions. Since you have identified a problem, there is likely an impact on the business or the customer. As a team, you should consider what can be done to limit or eliminate this problem in the short term. Remember this is just a containment action and should not be seen as a long-term fix. 

In our situation we decided to “Implement temporary overtime shifts to meet production goals, leading to an increase in labor costs.”

At this stage, the A3 should look similar to the one below; you can use charts and graphics to represent the current state as well if they fit within the limit area. Remember, we must include the content of the A3 within the 1-page A3 Document.

Step 2: Set the A3 Goals

The next step of the A3 is to, as a team, set the goal for the project. As we have a clear understanding of the current condition of the problem, we can use that as our baseline for improvement and set a realistic target for improvement. 

A suggested method for setting the Target condition would be to use the SMART Target method.

If you are not familiar with SMART Targets , read our guide; it will cover the topic in much more detail. In short, a SMART target creates a goal statement that is specific, measurable, achievable, relevant and time-bound. 

By doing this you make it very clear what the goal of the project is, how it will be measured, it is something that can be achived, relevant to the needs of the business and has a deadline for when results need to be seen.

For our A3 we decided that the goal would be “Our goal is to achieve at least a 20% reduction in machine downtime on Automotive Assembly Line No.3, lowering it from 90 minutes to no more than 72 minutes per day per machine, within the next 60 days. This reduction is crucial for increasing productivity and reducing labor costs, aligning with our overall business objectives.”

I also recommend using charts in this section to visualize the benefit or improvement to ensure you have stakeholder and sponsor support. Visuals are much easier and faster for people to understand.

At this point, your A3 might look something like the one below, with the first 1/4 or section complete. The next step is to move on to the root cause analysis to get to the root of the problem and ensure the improvement does not focus on addressing the symptoms of the problem.

Step 3: Root Cause Analysis

Root cause analysis is the next step in the process, often referred to as gap analysis, as this step focuses on how to get to the goal condition from the current condition.

Tip: If at this point you find the team going off-topic and focusing on other issues, Ask the question, “Is this preventing us from hitting our goal statement?”  I have found this very useful for keeping on track in my time as an A3 facilitator.

For root cause analysis, a couple of key tools are usually used: a fishbone diagram and a five-why Analysis . Again, we won’t go into the full details of these tools within this guide, as they have been covered in extensive detail in their own guides.

But the aim at this point is as a team, to brainstorm what is preventing us from achieving our target condition. This is done by allowing all members of the team to input the reasons they think it is not being achieved. These inputs are often written on sticky notes and placed on the fishbone diagram. Following this, you may have results similar to the ones below.  Note: it is important that the inputs are specific so they can be understood. e.g. “Calibration” alone is not specific to how it’s causing the problem; specify it with “Calibration: Inaccurate measurements affecting machine settings.”

After the fishbone diagram has been populated and the team has exhausted all ideas, the team should then vote on the most likely cause to explore with a 5 Whys analysis. This is done because, due to resource limitations, it is unlikely all of the suggestions can be explored and actioned.

In this situation the team decided the “lack of preventative machines: machines not being serviced regularly” was the cause of increased downtime. This was explored with the 5 Whys to get to the root cause of why Assembly line 3 did not have preventative maintenance implemented.

The result of this root cause analysis can be seen below, and you may end up with more ideas on the fishbone, as generally there are a lot of ideas generated by a diverse team during brainstorming.

Step 4: Solutions and Corrective Actions

Now that we understand what the root cause of the problem is, we need to address it with solutions and corrective actions. Again, as a team, consider the root cause of the problem and discuss what actions need to be taken by the team, who will do them, and when they will be done. The result should be an action plan, for example, like the one below:

This action plan needs to be carried out and implemented.

The result of this section will likely just be an action list and look like the below section.

Step 5: Validate Solution and Standardize

Within step 5 it is time to collect data to validate and confirm the actions that have been implement resulted in solving the problem and met the target state of the problem. This is done by continuing to collect data that demonstrated the problem in the baseline to see if the problem is being reduced.

For example, below, the project team continued to collect Assembly Line 3 downtime data on a weekly basis. Initially, there was a steady reduction, likely due to the focus of the project on the problem, which had some impact. However, once the majority of the action was implemented, a huge drop in product downtime was seen, exceeding the target. This showed the actions has been successful

If, in the validation stage, you find that the improvement required is not being made, you should go back to step 3 and reconsult the root cause analysis with the team, pick another area to focus on, and create an action plan for that following the same steps.

Step 6: Preventive Actions and Lessons Learned

In step 6 after the confirmation of project sucess you should look at preventive actions and lessons learned to be shared from this project:

• Preventive Action: The new preventive maintenance schedule will be standardized across all assembly lines. This will prevent other lines having similar issues and make further improvements
• Lessons Learned: A formal review will be conducted to document the process, including challenges faced and how they were overcome, which will then be archived for future reference.

In our project, this looked like the below and will be used as a reference point in the future for similar issues. 

And that is the successful completion of a structured A3 problem-solving technique.

The complete A3 looks like the below image. Yours may slightly differ as the problem and information vary between projects.

An A3 Report is a Toyota-pioneered practice of getting the problem, the analysis, the corrective actions, and the action plan down on a single sheet of large (A3) paper, often with the use of graphics. At Toyota, A3 reports have evolved into a standard method for summarizing problem-solving exercises, status reports, and planning exercises like value-stream mapping.

But it is much more than a sheet a paper with facts and figures. It is a management process  learned through dialogue about concrete problems. It does this by means of a dialogue between a lean manager and a subordinate who learns lean management and leadership as she solves an important problem.

This process of solving problems while creating better employees—A3 analysis—is core to the Toyota management system. An A3 report guides the dialogue and analysis. It identifies the current situation, the nature of the issue, the range of possible counter- measures, the best countermeasure, the means (who will do what when) to put it into practice, and the evidence that the issue has actually been addressed.

The lean leader’s job is to develop people. If the worker hasn’t learned, the teacher hasn’t taught. Training Within Industry Report (Washington, DC: War Manpower Commission, Bureau of Training, 1945).

Effective use of the A3 process can facilitate the shift from a  debate  about who owns what (an authority-focused debate) to a  dialogue  around  what is the right thing to do  (a responsibility-focused conversation). This shift has a radical impact on the way decisions are made. Individuals earn the authority to take action through the manner in which they frame the issue. They form consensus and get decisions made by focusing relentlessly on indisputable facts that they and their peers derive from the gemba.

As a result, A3 management can best be understood as neither “top-down” nor “bottom-up.” The process clarifies responsibility by placing ownership squarely on the shoulders of the author-owner of the A3, the individual whose initials appear in the upper right-hand corner of the paper. This person may not have direct authority over every aspect of the proposal. Yet this owner is clearly identified as the person who has taken or accepted responsibility  to get decisions made and implemented .

Example A3s

The Many Facets of A3

• A standard paper size:  At its most fundamental, “A3” is the international term for a sheet of paper 297 millimeters wide and 420 millimeters long. The closest U.S. paper size is the 11-by-17-inch tabloid sheet. 
• A template:  Many companies and individuals use an A3-sized document pre-printed with the steps needed to conduct lean problem-solving or improvement efforts, with generous white space for “A3 owners” to record their progress. While they refer to this document as a template, an “A3” is not a template.
• A storyboard:  As users record their problem-solving or improvement project’s progress, the A3 becomes a storyboard used to facilitate communication, collaboration, and coordination with other stakeholders affected by the goal the A3 owner is working toward (e.g., solving a problem or improving a  process ). By having all the facts about the effort in one place, logically presented and summarized, the A3 owner is better able to gain buy-in from other stakeholders for recommended process changes. 
• A report:  Once the A3 problem-solving effort concludes, the A3 storyboard serves as a report of the problem-solving or improvement initiative, including the facts and data gathered, hypotheses considered, countermeasures tried, experiment results, corrective actions taken, and the overall thinking of the A3 owner and stakeholders. At Toyota and elsewhere, A3 reports have evolved into a standard method for summarizing problem-solving exercises, status reports, and planning exercises like value-stream mapping.  
• A problem-solving methodology (or process):  Most lean practitioners know “the A3” as a problem-solving process guided by specific steps or questions. The left side of the A3 focuses on various elements of the problem or current condition, and the right on the countermeasures considered, tested, and chosen that resolves the issue or creates a higher standard.
• A management discipline (or process):  At a higher level, lean leaders, managers, and supervisors use “the A3” as a means by which they oversee and guide subordinates while simultaneously helping them develop their  lean thinking and practice  — particularly lean leadership and problem-solving — capabilities. With A3 management, leaders challenge their direct reports to solve a problem. Then, with the A3 report guiding the dialogue and analysis, leaders coach them through the problem-solving process. Importantly, leaders coach by asking questions versus providing answers, ensuring responsibility remains with the subordinate to solve the problem by pursuing facts and building consensus. Through this interaction, subordinates address the issue, allowing them to make progress toward the objective and, in so doing, learn the lean approach to leadership and management and gain problem-solving capability.
• A3 thinking (or analysis):  Most A3 coaches and advanced lean practitioners refer to “the A3” as a thinking process. In this case, the term refers to a systematic approach to resolving problems or improving  work  processes. Someone can follow this systematic approach, regardless of whether they are guided by or record their findings on an A3 document.
• An alignment tool:  Advanced lean organizations that have incorporated lean thinking and practices throughout their operations use “A3s” as part of their  strategy deployment  and execution efforts. In this case, the A3 process ensures a standard approach to managing and  coaching  people, all directed toward solving problems that help achieve corporate objectives.

A3 Thinking

Last updated by Jeff Hajek on February 17, 2024

What is A3 Thinking?

A3 thinking is a philosophical approach to problem solving that centers on a well- communicated team approach to using the PDCA cycle . The tool used to apply this way of thinking is known as the A3 report.

Watch this A3 Thinking Video

A3 Thinking Background

Whether you are a leader or a process owner, a big part of your job will entail problem solving. Taking on problems in a haphazard, random manner is a recipe for inconsistent results. A3 thinking, while not a magic solution to problems, does increase your chances of successfully solving them. The power of the A3 report lies in the structured approach it takes to solving problems.

A3 Thinking is a Structured Form of Problem Solving

Before diving into the A3 report, though, let’s take a look at what a problem is. Essentially, a problem is any situation when “should be” does not match reality.

That gap develops in one of two ways. Either the target gets higher, or performance drops. Regardless of how the gap came to pass, the basic problem-solving system is the same, even though the specific actions taken to close the gap may vary.

Problems with Problem Solving

There are three common failure modes that keep people from effectively solving problems.

• They treat symptoms. Treating just the surface issue leaves the root cause untouched. It will likely pop out sideways, possibly in a worse way.
• They don’t set clear goals . Without a clear end point, it is impossible to know when to stop working. Furthermore, people won’t agree on whether the project was successful or not.
• They don’t build consensus. Most significant problems cross team boundaries. Without support from affected people, problem solving fails. 

PDCA (Plan-Do-Check-Act)

At the heart of most effective problem-solving methodologies is the PDCA Cycle (aka the Deming Cycle).

• Plan: Create a solid plan for solving the problem. This should include creating a deep understanding of a problem, identifying the root cause, defining the problem, and setting goals.
• Do: The plan must be implemented.
• Check: Poor problem solvers stop after the “Do” step. Good problem solvers check to see if the solution they put in place really worked.
• Act: When you identify an area where the “Do” step fell short, you must actually fix it.

The A3 Report

The A3 process is a specific, structured method of problem solving. While the A3 report is the visible centerpiece of the process, it is actually more of a result of the process than the actual process itself. The A3 report is simply a concise, communication tool. Because of the recognizable format, individuals can rapidly share ideas and have confidence in what they are talking about.

A3 Thinking Relies on the Use of PDCA

The A3 report gets its name from the “A3” size of paper used in Japan where the report originated. It is relatively close to the size of an 11×17 sheet of paper in the US.

As you continue to read about the A3 report, keep in mind that there is no set format, other than that the sections should follow the PDCA cycle. Templates (such as the ones offered at www.Velaction.com/a3-template/ ) are handy to use as starting points, but feel free to deviate from the precise layout if there is a good reason to do so. One warning, though, if you do make a change: make sure that sufficient space is devoted to the plan step.

A3 Communication

The A3 report is not intended as a tool for independent use. A3 reports involve several people. There should be an owner who is responsible for maintaining the document and managing the problem-solving efforts.

He or she should also have an experienced mentor who can help guide the problem solver through the A3 process. This mentor typically uses a healthy dose of the Socratic Method, pointing the person toward ways to overcome roadblocks rather than actually giving answers. The mentor, in many cases, also lends his authority to the A3 report, so the problem solver acts on the mentor’s behalf in solving the problem. This implies that the mentor needs to have some clout in the organization. Because of the mentor’s support, there is authority strapped to the A3 report. That translates to higher prioritization.

There will also be a variety of stakeholders with a vested interest in the outcome of the A3 project.

Finally, there will be the people involved in data collection, analysis, and, of course, implementing the solutions.

In most organizations, people are busy, and there is a lot coming at them. They have to separate the wheat from the chaff. One of the benefits of the A3 process is that it gets people’s attention. It is generally used for only the most significant problems in the organization, so people tend to take notice when they see the A3 report.

Another big reason that people pay attention to A3 reports is that the somewhat standard format lets them quickly get a handle on what is going on. The A3 report acts as a standardized communication tool. Readers can follow the storyboard and, without much wasted effort, know the background and status of the project.

The A3 Process

A3 thinking takes a systematic approach to problem solving. Typically, a project owner draws up the A3 report with ample support and input from all involved people. The author then runs it by the mentor throughout each step. The feedback and ideas from the discussion are then integrated into the report.

The background section is exactly what it sounds like. It is a brief section that clarifies the problem and adds context. Metrics are often shown in this box.

• Current Conditions

The current conditions section summarizes, not surprisingly, the current situation. It can show an overview of the process, highlight problems, or present anything else that will help people gain understanding of how things are now.

Specific goals should be set. In most cases, goals should have dates associated with them. An A3 report, though, is a storyboard to guide you through a process. At this point, you only know where you want to go, not how long it will take to get there. The goal dates will come out indirectly in the countermeasures step. Once the project is more fully fleshed out, though, you should add dates to the goals.

• Root-Cause Analysis

This step can take a substantial amount of time, as it is the most important one. If the root cause is not clearly identified, you’ll be solving the wrong problem. Mentors should spend significant time reviewing this step to make sure the author has it right.

• Countermeasures

Only when the root cause is understood should an A3 report author start coming up with solutions. For big projects, the countermeasures listed here might have action plans associated with them. Of particular importance is that the projected improvements from the countermeasures should add up to reach the goal.

• Effect Confirmation

It is particularly important that the effects of the countermeasures are confirmed. On occasion, positive but unexpected changes happen. If they were not predicted with the countermeasures, the root cause is likely still present. Go back and try again, or you’ll be starting the whole project over down the road.

• Follow-Up Actions

Follow-up items are not things that have to be done to get a new process up and running. They are intended to capitalize on an opportunity to add further improvement, or to help spread knowledge. In no case should the failure to do a follow-up action item prevent the full implementation of the solution.

Let me stress that point…

The success of a project should not be contingent upon follow-up actions.

If the action item list is never touched, the gains you made should be real, and they should stick. Follow-up items should be focused on going beyond the goals, or simply ‘buttoning down’ loose ends.

Benefits of A3 Thinking

• The consistency of the process supports the mentoring
• The systematic approach and recognizable format promote collaboration.
• The A3 process acts as a hands-on classroom, promoting learning and growth.
• Because of the methodical approach, solutions are more likely to have permanent fixes.
• The A3 report’s format makes it easy to spread gains around the organization.
• The act of assigning a problem-solving owner increases the likelihood of a successful project.
• The economy of language in the A3 report engages people. They know they won’t have to waste time trying to figure out what is going on.
• The collaborative process means more effective decision making.

Words of Warning With A3 Thinking

• No problem is ever truly solved. You can always go further. Some people make a point of avoiding the word “solved” altogether. You don’t need to go to that extreme but do keep in mind that improvement is an ongoing process and you will likely address the same process repeatedly over the years. You’ll identify incremental improvement opportunities, changing customer requirements will demand further improvement, or you’ll be fighting back entropy as outside forces affect your processes.
• While purists advocate handwriting an A3 report, the world is a changing place. Teams are often spread out around the whole globe, and more people than ever are working remotely. In the spirit of continuous improvement , adapt the report to suit your needs. A good technique is to handwrite the section you are working on, and then transfer it to a computer for ease of update, review, and transmission.
• Don’t expect immediate expertise in A3 reports. You’ll need a lot of practice to get good at them.
• Don’t expect immediate expertise in A3 reports. You’ll need a lot of practice to get good at them. (Note that this is intentionally mentioned twice. It is that important.)
• Don’t focus heavily on the report. The A3 thinking process is far more important.
• Use copious graphics on the report. They take far less space than words and are much clearer.
• Make sure targets are specific. Collaboration requires clarity in what people are agreeing to.
• Keep an appropriate scope . The A3 report is not an annual plan. It should be focused on a specific problem. Think “reduce dings on doors”, not “improve quality”.
• Don’t move forward without consensus. If stakeholders are not bought in…

In an organization that embraces A3 thinking, you will have a big role to play. While you may not be designated as the author or owner of a report, there is a great likelihood that you will see people visiting your work area, scribbling on large sheets of paper.

You will probably be asked many questions and may even be asked to collect data . If you are approached with an A3 report, ask to see it. It will give you a better understanding of how the A3 team leader sees the problem. Chances are you are closer to the process than he or she is and can probably offer some great insight. You may even identify an error that can help prevent your life from being harder down the road.

A3 Thinking and Promotions

If you aspire to move up in your organization, the A3 process is a great way to show what you can do. They tend to be used for important projects and have a good deal of attention paid to them by the decision-makers in the company. Ask your boss for some opportunities to participate in the A3 process.

Tip: Sitting in on a mentor meeting is a good way to gain knowledge about the process a little more quickly.

If you want to be a top performer in a Lean company, make A3 thinking your go-to problem solving methodology for anything that crosses a functional boundary or involves multiple work areas. In addition to helping you develop critical thinking, it hones several other skills that will be invaluable to you.

Many new leaders struggle with talking to senior managers. The A3 report gives them experience in a structured manner. They know what to expect, are working on something positive, and have a chance to be well-prepared for the meeting. It can provide a great opportunity to build a network.

That network building also extends to managers at equal levels. In some companies, leaders are so compartmentalized they seldom get to know their peers as anything more than casual acquaintances. Working together on an A3 report helps build strong relationships.

Communication skills are also refined. Put bluntly, many managers are horrible writers. Grammar aside, it can be a challenge to figure out what a person is saying. Sugar coating abounds. People are reluctant to commit to an idea…

Key Points About A3 Thinking

• A3 thinking is more than just filling out an A3 report. It is a way of training oneself to approach problem solving and leadership in a structured manner.
• A3 thinking is a structured thought process that is based on the PDCA cycle.
• The A3 process is not an individual activity. It requires the effort of the whole team.

Next Steps to Creating an A3 Report

• Determine if your organization has anyone with experience in mentoring others on A3 Thinking. (If you do not have anyone who can help train your organization and need help, contact us at [email protected] .)
• ID a few key people for each A3 mentor to develop.
• Train the team members on the Fundamentals of A3 Thinking .
• Identify basic projects for each individual to lead.
• Complete the projects, meeting periodically to help individuals learn from each other.
• Repeat with increasingly challenging projects.

A3 Problem Solving | A3 Root Cause Analysis

Problems are inevitable, no matter how hard we plan and what precautions we take, they will eventually creep up and bite us. Rushing in and trying to fix the problems quickly, however, rarely seems to truly make these problems go away. Often, they come back time after time. The reason for this is that we fail to use a methodical approach to identify the true root causes of the problems and fail to put in a robust fix that will prevent the problem reoccurring.

A3 problem solving is one easy way to put in place a process that will help you to solve problems permanently as well as making improvements to your processes.

What is A3 Problem Solving

As with many things from Toyota, A3 problem solving attempts to make things as simple and as visual as possible. A3 refers to the paper size used for the reporting and all the process is contained within the confines of this single sheet of 11” by 17” paper. Some suggest that the reason for the single piece of paper is down to the rumored refusal of Taiichi Ohno to read any more than a single page of any report.

There is nothing magical or revolutionary about the process either. It simply follows the Deming’s Plan-Do-Check-Act Cycle or PDCA. It is also very similar to other processes and layouts that other companies have used over the years such as Ford’s 8D process for problem solving.

The effectiveness of the form however lays more in the attitude of the teams implementing the A3 process than the form itself. Problems are opportunities to improve what you are doing and should never simply be seen as just a “problem”.

A3 problem solving sheets are not going to be a magic wand that you can wave over your problems to solve them. Without a dedicated team to follow the process they are unlikely to help you.

The A3 Problem Solving Process

The A3 root cause analysis process is usually broken down into 7 steps, some break it down into 8 or 9, however the total number of steps and what they are called are not important as long as you follow the idea behind them. The steps follow the PDCA process and take you through a logical step by step route to clearly identify:

• What is the problem
• Why we need to fix it
• What is the actual root cause
• How we will contain the problem in the short term
• Plan how we fix the root cause
• Confirmation that the countermeasures fix the issue
• Changes to standardized work to fix the issue permanently
• Share any changes within the company

Often these steps are broken down under the following headings on the A3 worksheet:

Current Situation

• Targets or Goals

Root Cause Analysis

Countermeasures.

• Implementation Plan

This is what should be considered and detailed within each section:

• What is the actual issue that you are looking to correct?
• How does it impact the business objectives? Why do we need to fix it?

It is always best to take your team to where the problem is occurring to see the problem firsthand. Talking about something in a remote location is never going to be as effective as actually observing at the Gemba (Workplace).

The team should carefully detail the problem. This should cover all relevant information such as how often something happens, when, where, etc. Depending on the complexity of the issue it may be necessary to collect data in the form of graphs and control charts or to conduct process mapping exercises to understand what is happening.

Targets / Goals

What does the team see as the ideal solution to the problem? What are we going to achieve? Your objectives should be clearly stated, and a time frame agreed so that all can agree on what you hope to do through your team.

There are of course many ways that you can arrive at the root cause of your problems depending on the complexity of the problem that you face. The right quality improvement tools should be selected and used from Pareto charts to fishbone diagrams or the 5 whys.

Ensure that your A3 root cause analysis comes up with agreed reasons for your problems. Remember, that there are often multiple causes that may need to be fixed.

Once you have your root cause(s) identified you can get to work to brainstorm the changes that you need to make to fix the problems. Remember that all fixes should aim to achieve the goals that you have identified earlier in the process.

Action Plan

This is your plan of action to fix the problem that you have identified. This plan should be detailed and include what is to be done, who is responsible, and of course when it will be done by. You should also consider the expected outcome from each action so that you will have a clear idea of whether the action has had any effect on your issue.

Once the plan has been detailed it should be implemented effectively by the team.

Too often teams will stop at the plan implementation stage. They make the changes that they have suggested and then fail to check if those actions have been effective. You must verify the effectiveness of your actions to confirm that they have fixed the root causes that you have identified. Otherwise the problems could easily return.

If the changes have not managed to fix the problem, then the process needs to be revisited. The team needs to work through the cycle once again to see what they have missed and to make alternative plans to fix the problems.

Changes should be made permanent if they are found to be effective through changes to standardized work and other procedural documentation.

Teams should also share what they have learned and implemented within the company. Often there is the opportunity to mirror the changes made to prevent issues occurring in other parts of your business.

Why Use A3 Reporting

The A3 reporting format does not have to limited to simply problem solving. Toyota use it for a number of things such as status reports, improvement suggestions and proposals. Other companies have developed similar reports for things such as coaching. Your imagination and business needs are your only limitation.

The A3 lean process is highly flexible and provides you with a highly visible way to communicate everything from your problem solving to continuous improvement initiatives. Used well with trained and dedicated teams it can really make a huge difference to your company.

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.

Lean Six Sigma combines two methods that streamline business processes in order to reduce waste, improve quality, and increase efficiency and product value. Both approaches originated in the manufacturing industry - Lean by Toyota and Six Sigma by Motorola - but today they are used to improve many processes within an organization, from customer support to administration.    The templates provided here are suitable for Yellow, Green, and Black Belts. You’ll find Six Sigma project templates designed to support the different phases of an improvement process, all of which are free to download. Simply click on the link to download and open a template file, and customize it to suit your needs.

Six Sigma Tools

Six Sigma is a quality measurement that represents 3.4 Defects Per Million Opportunities. That’s a lofty goal for many business processes, but you can use Six Sigma methods to improve quality and performance in varying degrees based on the needs and objectives of a business or project. Six Sigma tools range from statistical charts, illustrative diagrams, and data collection methods to project management and process analyzation worksheets. These tools may not be exclusive to Six Sigma, but they can be applied in specific ways to focus on process improvement. The tools required depend on the project requirements and team roles. Depending on one’s training and experience, a Six Sigma professional may be involved in improvement initiatives at the White, Yellow, Green, or Black Belt level. White Belts generally have supporting roles, while Yellow Belts act as team members, Green Belts collect and analyze data, and Black Belts serve as project leaders.    In the following sections, you’ll find a number of free, downloadable templates that you can use as Six Sigma tools.

How Lean and Six Sigma Work Together

While both Lean and Six Sigma aim to reduce waste, they are distinct methodologies. Six Sigma focuses on reducing defects by limiting variation within a process, while Lean removes unnecessary steps for a more efficient process. Combining these two methodologies can improve business performance by emphasizing both quality improvement and profitability. Learn more about Lean Six Sigma by reading Everything You Need to Know About Lean Six Sigma .   The acronym “DMAIC” represents a key aspect of Lean Six Sigma. DMAIC stands for the five phases of an improvement cycle: Define, Measure, Analyze, Improve, Control. You can use these steps as a roadmap for resolving issues with a Six Sigma approach:  

• Define the project goals or problem to be addressed, internal and external customer requirements, and project boundaries.
• Measure the current performance of the process and describe the process in quantifiable terms.
• Analyze the process and identify the root causes of defects and sources of variation.
• Improve performance by resolving the root causes of issues and eliminating defects.
• Control future process performance by maintaining improvements.

  Another version of this process is DMADV (Define, Measure, Analyze, Design, and Verify). The DMADV framework is typically applied to new products or services, rather than improving an existing process, or when an existing process has been improved but is not meeting a Six Sigma level. The process is similar to DMAIC but focuses on product or process design and how to implement that design effectively.

A3 Methodology

Purpose  A3 problem solving is part of the Lean management approach to quality improvement (QI). However, few tools are available to assess A3 problem-solving skills. The authors sought to develop an assessment tool for problem-solving A3s with an accompanying self-instruction package and to test agreement in assessments made by individuals who teach A3 problem solving.

Methods  After reviewing relevant literature, the authors developed an A3 assessment tool and self-instruction package over five improvement cycles. Lean experts and individuals from two institutions with QI proficiency and experience teaching QI provided iterative feedback on the materials. Tests of inter-rater agreement were conducted in cycles 3, 4 and 5. The final assessment tool was tested in a study involving 12 raters assessing 23 items on six A3s that were modified to enable testing a range of scores.

Results  The intraclass correlation coefficient (ICC) for overall assessment of an A3 (rater’s mean on 23 items per A3 compared across 12 raters and 6 A3s) was 0.89 (95% CI 0.75 to 0.98), indicating excellent reliability. For the 20 items with appreciable variation in scores across A3s, ICCs ranged from 0.41 to 0.97, indicating fair to excellent reliability. Raters from two institutions scored items similarly (mean ratings of 2.10 and 2.13, p=0.57). Physicians provided marginally higher ratings than QI professionals (mean ratings of 2.17 and 2.00, p=0.003). Raters averaged completing the self-instruction package in 1.5 hours, then rated six A3s in 2.0 hours.

Conclusion  This study provides evidence of the reliability of a tool to assess healthcare QI project proposals that use the A3 problem-solving approach. The tool also demonstrated evidence of measurement, content and construct validity. QI educators and practitioners can use the free online materials to assess learners’ A3s, provide formative and summative feedback on QI project proposals and enhance their teaching.
