A3 Problem Solving
a3 report · toyota a3
TL;DR
A one-page (A3-sized) lean problem-solving template that walks a team from background and current state to root cause, countermeasures, and follow-up.
The A3 is a lean/Toyota problem-solving format that fits a complete PDCA cycle on one A3-sized page: background, current condition, goal, root-cause analysis, countermeasures, implementation plan, and follow-up. It forces concise, evidence-based storytelling and is widely used in operational-excellence CAPA programs.
V5 offers an A3 view of any deviation/CAPA so a complex investigation can be reviewed in one glance.
