Speed and stability.
Research from the DORA programme, published in Accelerate by Forsgren, Humble and Kim, found four metrics that predict delivery performance. DORA has since renamed one and added a fifth.
Deployment frequency
Speed
How often you release to production.
Lead time for changes
Speed
Commit to running in production.
Change failure rate
Stability
Share of releases that cause a failure.
Time to restore
Stability
How fast you recover from a failure.
