Core answer

What is A3?

A3 is a way to make problem solving visible on one compact page. It forces teams to connect context, goal, analysis, causes, countermeasures and learning points logically.

Practical view

What is PDCA?

01

What does PDCA stand for?

PDCA stands for Plan, Do, Check, Act. It is a learning process in which you formulate a hypothesis, test it, check the effect and update the standard.

02

Why does A3 belong with PDCA?

A good A3 follows PDCA logic. The document is not the goal; the conversation and learning around the problem matter more.

03

What is a countermeasure?

A countermeasure is a targeted action against a suspected cause. It is tested, followed up and adjusted based on what the process shows.

Deepening

From symptom to cause

02

Which course deepens A3 and PDCA?

Toyota Business Practice focuses on structured problem solving with A3 thinking, cause investigation, decision-making and PDCA.
