An engineering manager is assembling a balanced DevOps scorecard and wants the four metrics that the DORA research programme identifies, two describing delivery throughput and speed and two describing stability of releases. Which set of four metrics matches the DORA framework?
- AVelocity, sprint burndown, story point throughput, and team capacity, pairing planning forecasts with execution tracking to describe how predictably the team delivers committed scope.
- BDeployment frequency, lead time for changes, change failure rate, and time to restore service, pairing two flow measures of throughput and speed with two stability measures of release reliability. Correct
- CDeployment frequency, lead time for changes, mean time between failures, and code coverage percentage, pairing two flow measures with two reliability indicators drawn from testing and operations.
- DCycle time, escaped defect count, change failure rate, and time to restore service, pairing a flow measure and a quality count with two stability measures of how releases behave in production.
Why A is wrong: These are Agile planning and tracking measures rather than the DORA set, so they describe sprint predictability instead of delivery throughput, speed, and release stability.
Why B is correct: These four are exactly the DORA metrics, with deployment frequency and lead time describing flow and change failure rate and time to restore service describing stability, matching the scorecard the manager wants.
Why C is wrong: Two of these belong to DORA, but mean time between failures and code coverage are not DORA stability metrics, so the set mixes in measures from other disciplines.
Why D is wrong: Cycle time and escaped defect count are not the named DORA flow metrics, so although two stability measures are correct the flow side of the set is wrong.
