A3 Report Generator

What is an A3 report?

An A3 report condenses a problem-solving argument: what is happening, why it matters, what may explain it, and how a team will test an improvement. The value comes from the reasoning between sections, not from filling every box.

Use it for a bounded process problem

Choose an A3 when a measurable gap needs investigation and a manageable improvement cycle. A broad strategy discussion usually needs more scope than one problem statement can hold.

Make the reasoning testable

1. Describe the gap. A current measure and a target are clearer than a complaint that the process is slow.
2. Separate facts from causes. An observed delay does not establish why the delay occurred.
3. Tie actions to analysis. Each countermeasure should address an identified cause or test a hypothesis.
4. Assign accountable owners. Name who will carry out the action and when evidence will be reviewed.
5. Plan the check. Define the result that would support keeping, changing, or abandoning the countermeasure.

A structured draft for the improvement discussion

MyMap arranges your problem statement and notes into an A3-style report. The complaint-resolution example includes background, current condition, root cause analysis, target condition, countermeasures, implementation, and follow-up; its numbers are illustrative.
