A3 Problem Solving — Think on One Page
The A3 problem-solving framework used at Toyota and world-class teams. Background, current state, root cause, countermeasures — on a single page.
The framework
A3 (Background→Current→Goal→Root Cause→Countermeasures→Effect→Follow-up)
The A3 framework tells a complete problem-solving story in seven sections on one page. The discipline of fitting everything onto one sheet forces you to prioritise, clarify, and communicate with precision. It is both a thinking tool and a communication tool.
How you'll learn
Text-first. Practice-heavy. No video lectures.
15-minute text lessons
Short, dense reading you can finish between meetings — not hour-long video lectures.
Hands-on exercises
Apply the framework to a realistic scenario, right in the module where you learned it.
Quizzes & assessments
Check your judgment, not just your memory — most questions are situational.
Certificate on completion
Finish a course and get a shareable certificate, automatically.
About this course
The A3 method forces you to fit an entire problem-solving story onto one A3 sheet of paper. This constraint is the point — it builds clarity of thought. Born at Toyota, A3 is now used by the world's best-run organisations to diagnose, solve, and communicate any problem.
The project: A3 for a Failing Sprint
Write a complete A3 for a provided case: a software team that has missed its last three sprint goals. You must diagnose the root cause, design countermeasures, and define how you will measure success.
