A fast pipeline that fails randomly is slower than a stable pipeline that teams trust.
I optimize in this order:
- Reliability (repeatability, stability)
- Signal quality (real failures vs noise)
- Execution time (parallelism, smarter test selection)

CI Reliability > CI Speed (Most Teams Get This Wrong)
Speed matters, but reliability is what builds trust. Here’s how I prioritize pipeline signal.
