The PDCA cycle: the order behind Kaizen
Plan, do, check, act. Where each step of the cycle sits in an improvement record.
13 October 2026 · 1 min read
PDCA (Plan–Do–Check–Act) is the basic cycle of continuous improvement. The steps of a Kaizen record follow it.
- Plan: define the problem, measure the current state, write the target.
- Do: try the change on a small scale.
- Check: measure the result, compare with the target.
- Act: standardise if it worked, re-plan if it didn't.
It isn't done until the loop closes
Many improvements stop at “do”: the change is made but not measured. Because measurement and sustainment follow-up are separate steps in the record, a half-finished cycle is visible.
