Lead Time for Changes

The time between a code change being committed and that change running in production.

What is Lead Time for Changes?

Lead Time captures the full delivery path: review, CI, staging, release. Architectural choices dominate this metric — a monolith with slow tests and a manual release train will dwarf small, well-factored services with a progressive delivery pipeline, regardless of individual coder speed.
