Draft outline details
Step by step
- Record a baseline: stage durations, queue times, and flake rate over two weeks.
- Find the longest stages and the dependency cache misses.
- Apply changes one at a time: dependency cache, parallel test shards, faster runners, quarantine flaky tests.
- Planned mistake: changing everything at once. Fix: change one thing per run so each effect is measurable.
- Compare with baseline, roll the template to other teams, and record hours saved.
