01Baseline metrics and optimization goals16 min
Define a baseline before proposing optimization.
Practice: Write an optimization brief naming metric, denominator, version, comparison window and minimum evidence.
02Candidate flow and wording changes16 min
Keep candidate changes inside permitted scope.
Practice: Label a wording change, new branch and ticket action by required review and potential side effects.
03Diff review and regression testing16 min
Review diffs and run meaningful regression tests.
Practice: Create a before/after diff summary and a regression matrix with explicit pass/fail evidence.
04Granular approvals and publish boundaries16 min
Approve an exact candidate through an authorized boundary.
Practice: Write an approval record and explain what happens if v9 appears before execution.
05Post-release comparison and rollback planning20 min
Plan observation and recovery before releasing.
Practice: Prepare release, monitoring and rollback records for a fictional successful, regressed and insufficient-sample case.
