Term	Kind	Topic	What it is
Branch Lifetime	metric	Trunk-Based Development	How long a branch lives before being merged, which determines integration pain and is the practical measure of whether integration is continuous.
DORA Metrics	metric	DORA Metrics	Four measures of software delivery — deployment frequency, lead time, change failure rate, time to restore — that resist gaming better than most.
Pipeline Feedback Latency Commit-to-Verdict Time, CI Feedback Time	metric	CI/CD	The time from pushing a change to knowing whether it passed, which sets the batch size engineers choose and therefore the size of every review, deploy and rollback.
Review Latency	metric	Code Review	The time between a change being ready for review and the review happening, which is usually the largest component of lead time.
