Problem
Scenario
You've changed an engineering process and want to know whether it actually improved outcomes. You need a way to separate real improvement from normal week to week noise, and to look beyond a single headline metric.
Question
How do you measure whether a process improvement actually worked?
What to Measure
- Primary outcome KPI, such as deployment lead time
- Leading indicators, such as review turnaround time or CI duration
- Lagging indicators, such as incident rate or rollback rate
- Guardrails to catch quality or team health regressions
