10 Best Steps of A3 Problem Solving Process

Toyota is well-known for its ongoing dedication to enhancing operational performance. How does a corporation with nearly 350,000 workers regularly and quickly improve? Using the A3 approach, a Lean thinking tool. See how the A3 Problem Solving Process aids firms in their pursuit of continuous improvement.

The A3 Problem Solving Process strategy assist enterprises in their pursuit of continuous improvement.

What exactly is the A3 Problem Solving Process?

Toyota created the A3 Problem Solving Process tool to encourage employees’ learning, teamwork, and personal improvement. The name “A3″ refers to the size of paper used to outline ideas, objectives, and goals during the A3 Problem Solving Process(A3 paper is also known as 11″ x 17” or B-sized paper).

Toyota employees A3 Problem Solving Process reports for a variety of typical types of work:

  • Problem-solving
  • Project status reporting
  • Making policy changes (policy meaning rules agreed upon and enforced by the group)

Why Should You Use an A3 Problem Solving Process?

Most businesses and teams are not collaborating as strategically as they could be. We leave meetings with half-baked ideas. We frequently move too quickly to begin working on implementing a solution, without first aligning on critical aspects. Rework and redundant effort, two indications of a lack of alignment, cause projects to proceed slowly.

The A3 approach enables groups of people to actively engage in a project’s purpose, goals, and strategy. It supports in-depth issue solving throughout the process and changes as needed to ensure that the project fulfils its intended aim as accurately as possible.

The A3 approach follows Abraham Lincoln‘s famous quote: “Give me six hours to chop down a tree, and I’ll spend the first four sharpening the axe.” The A3 Problem Solving Process method assists a company in sharpening its proverbial axes by promoting effective collaboration and bringing out the best in team issue solving.

Collaboration among creative individuals is essential for innovation and speed. Using the A3 approach to create cooperation can assist businesses and teams in making the best use of their time, money, and momentum.

What is the A3 Problem Solving Process Steps?

The A3 Problem Solving Process method consists of nine (actually, ten) steps.

1: Identify the issue

Because the A3 Problem Solving Process goal is to solve issues or answer needs, the first, partly unwritten, phase is to identify a problem or need.

2: Document the current state of affairs

Once you’ve agreed on the problem or need to be addressed, it’s time to document and examine the current state of affairs. Toyota recommends that problem solvers:

  • Observe the labour processes firsthand and record your findings.
  • Gather around a whiteboard and go over each stage of your procedure. You can use fancy process charting tools for this, but stick figures and arrows will suffice.
  • If possible, quantify the scope of the issue (for example, the percentage of tickets with long cycle times)# of late customer deliveries, # of mistakes recorded every quarter). If feasible, graph your data; visualisations are quite useful.

3: Perform a root cause analysis

Now that you have a better understanding of your process, try to identify the root reason for the inefficiencies. You can ask queries such as:

  • Where do we have communication breakdowns?
  • Where do we see long periods of inactivity?
  • What data do we require to communicate more effectively/smoothly?

Document these sore spots, then delve further. The 5 whys is a useful method for conducting an in-depth root cause analysis. The basic approach is to start with a problem statement and then question “Why?” until you find the true cause of the problem.

You may or may not need to ask why five times — this is just an estimate.

4: Create countermeasures to address the underlying causes

Countermeasures are your proposed solutions to the problem; modifications to your processes that will get the organisation closer to its ideal state by addressing core causes. Countermeasures should aspire to:

  • Specify the desired objective as well as the strategy for reaching it.
  • Make obvious, direct linkages between persons who are in charge of different parts in the process.
  • Loops, workarounds, and delays should be reduced or eliminated.

5: Specify your desired condition

You can clearly specify your desired state once you’ve chosen your countermeasures. You communicate our target state in the A3 Problem Solving Process by using a process map.

 Make a note of where the changes in the process occur so that they can be observed.

6: Create an implementation strategy

Now that you’ve established your desired state, you may devise a strategy for achieving it. Plans for implementation should include:

  • A to-do list for implementing countermeasures
  • Who is in charge of what?
  • Any time-sensitive job items have due dates.

The majority of teams prefer to document their implementation strategy in their A3.


7: Create a follow-up plan with expected outcomes

A follow-up strategy allows Lean teams to double-check their work and determine whether they truly grasped the present situation well enough to improve it. A follow-up plan is an important stage in process improvement since it can assist teams in ensuring that:

  • The implementation strategy was carried out.
  • The desired condition was met.
  • The expected outcomes were obtained.

The A3 report includes the first six steps. For their A3, most teams employ a template.

8: Ensure that everyone is on board

Any systemic reform should aim to improve every aspect of the system. This is why, before making changes, it is critical to include everyone who may be impacted by the implementation of the desired state in the conversation.

Consensus building is frequently the most effective strategy, which is why many teams incorporate it at each major turning point in the A3 Problem Solving Process. Depending on the scale of the project, it may also be necessary to notify executives and other stakeholders who may be affected by the work.

9: Put into action!

It is now time to put the plan into action. Follow through on the implementation as planned, keeping an eye out for possibilities for improvement along the way.

10: Examine the outcomes

In far too many cases, the A3 Problem Solving Process concludes with implementation. In order to learn, it is necessary to measure the actual results and compare them to your forecasts.

If your actual results differ significantly from what was expected, conduct a study to see why. Change the procedure if needed, and then repeat the implementation and follow-up until the goal is reached.

Examples of Lean A3 Problem Solving Process

Throughout the organisation, the A3 process is being used

Lean firms, like Toyota, frequently employ the A3 Problem Solving Process method to manage work at the project, programme, and portfolio levels. To accomplish this effectively, the A3 approach needs to be taught to the entire organization. This will allow for consistent, long-term A3 planning and thinking, enabling more effective collaboration throughout the business.

A3 on-going improvement

If you’ve spent any time in the Lean world, you’ve probably heard a lot about continuous improvement. It’s simple to say, but far more difficult to put into action.

Continuous improvement is difficult to implement since we don’t know how to squeeze it in between project-driven tasks. We talk about continuous improvement ideas at standups and meetings (“It would be fantastic if we could…”), but it’s difficult to find time to sit down and work on improving processes and policies.

The A3 Problem Solving Process method can help to structure and document continuous improvement activities. Many firms use the A3 approach to manage their continuous improvement initiatives in addition to project work.
