Free A3 Problem Solver (Lean canvas)
Structure your problem-solving narrative on one page — from current condition to countermeasures and follow-up — then export a PDF for reviews or coaching.
Start your A3
Open the example to see a complete story, or start from scratch for your own issue.
Capture background and the current condition with facts — charts, photos, and observations beat opinions.
Define the target condition, prove the root cause, and list countermeasures you will actually run as experiments.
Record plan and results, then standardise what worked — training, audits, and yokoten where it makes sense.
Why use an A3?
Complex problems pull teams into slide decks and email threads. An A3 keeps the narrative on one page so coaches, stakeholders, and front-line owners can ask better questions and see whether thinking is grounded in evidence.
In strategy deployment and operational excellence, A3s often feed tiered meetings, corrective-action systems, and capability development — without replacing your KPIs or your problem-solving standards.
Frequently asked questions
What is an A3? +
An A3 is a one-page problem-solving format popular in Lean and Toyota-style management. It forces clarity by telling the full story on a single sheet: what is wrong, what is true today, where you want to go, why the gap exists, what you will try, and how you will sustain the gain.
Is this the same as Toyota’s official A3 template? +
There is no single global standard. Organisations adapt headings to their context. This tool follows a widely used PDCA-style layout so teams can draft, review, and export a consistent canvas.
How does an A3 relate to 5 Whys? +
5 Whys is often the engine inside the “root cause analysis” box. You can run our 5 Why Analyzer separately, then paste the summary into the A3 root-cause section.
Can we use this in a tier meeting? +
Yes. Share the view mode in a daily or weekly review, capture actions in Edit mode, and export PDF for the record.
Do I need an account? +
No. Work in the browser. Email is only requested if you export PDF after your complimentary export on this device.
Bring your A3 draft and we will pressure-test the logic, links to KPIs, and how you run reviews in Kanrix.
