Dev Team Metrics that Matter
summary
Dora’s four metrics are given with concrete benchmarks: elite cycle time < 1 hour, high 1 day–1 week, medium 1 month–6 months; deployment frequency, change failure rate (elite 0–15%), and MTTR. LinearB adds a measurable PR-size effect: PRs under 200 lines merge twice as fast (100 lines ≈ 2 days, 500 ≈ 5 days). Practical tooling shown includes PR enrichment (estimated review time, diff snapshot), Slack notifications, inline approve and an upcoming GitStream rules engine for automated assign/merge (early beta).
