PDCA

Structure improvement as a cycle: plan the change, test it, check the result and standardise or adjust.

Official AIAG reference ↗

Data and preparation

Problem, baseline, target, hypothesis, test plan, result and decision

Practical workflow

  1. PLAN — scope the problem, baseline and desired result.
  2. DO — test the change in a controlled scope.
  3. CHECK — compare the result with criteria defined in advance.
  4. ACT — standardise what works or adjust and repeat the cycle.

Connection to AIAG

PDCA is used here as a supporting improvement cycle. AIAG CQI-20 provides the problem-solving framework QAPP links it to; QAPP does not label PDCA itself as an AIAG Core Tool.

Common trap

The diagram or question sequence is not the result. A cause becomes credible only when it is supported by evidence and the corrective action changes the predicted mechanism.
