“Create a PDCA cycle for software release quality: review recent defects and define a release-quality goal, add a pre-release test checklist for one service, compare escaped defects and release delays, then either add the checklist to the release process if the goal is met or improve the checklist and test again.”
図の背後にある意思決定を読み解く。
Define the quality result the team wants before changing the process.
Test the checklist with one service first.
Compare defects with the time added to each release.
Keep a useful check and revise one that does not help.
Use this cycle when delivery teams want to improve a repeated release activity with evidence from production.
よくある質問
What are escaped defects?
They are defects that were not found before release and are discovered in production or by users afterward.
Why compare release delays as well as defects?
A quality control should reduce risk without adding unnecessary delay, so both outcomes need review.
Can the checklist be changed after a failed pilot?
Yes. The Act step directs the team to improve the checklist and run another cycle with the revised version.
