Engineering Delivery Metrics

The delivery-health standards we hold ourselves to.

What these are

We measure our engineering against the four DORA metrics (from Google's DevOps Research and Assessment program) — the industry's standard yardstick for shipping software quickly and safely. The top-performing band is called "Elite."

Our targets

MetricWhat it measuresOur target (Elite)
Deployment frequencyHow often we ship to productionAt least once per day
Lead time for changesFrom a code change to it being liveUnder 1 day
Change failure rateHow often a release needs an urgent fix15% or less
Time to restore serviceHow fast we recover when something breaksUnder 1 hour
noolstack is pre-release. These are the targets we engineer toward; live measured figures will be published here once we're operating in production.
