Use the A3 form to tell the story of a problem, its analysis, and its solution. It is traditionally limited to the size of a single sheet of paper.

Answers the questions:
  • What is the problem?
  • What is the problem's root cause?
  • What are the countermeasures or actions that can be taken to solve the problem?
  • What are the solutions?
  • What are the future activities?


  • Make the A3 form fit your situation.
  • To make the form easier to print, organize, and view, create a series of A3 sub-forms, for example, A3 header, A3 current state deficiencies, and A3 root cause analysis.
  • Use the A3 form to plan for future activities.


  1. Complete the header section.
  2. Define the problem.
  3. Document the results of the root cause analysis.
  4. Document the current state with data from VSMs, Pareto Charts, Bar Charts, and so on.
  5. Identify the metrics that you will use to track the improvement progress.
  6. Identify the tasks required to implement the plan.
  7. Document the future state with data from VSMs, Process Maps, Charts, and so on.
  8. Revise as needed.
