Work out release readiness score instantly with clear inputs, formula shown and shareable results.
Readiness is more than a green test suite. This score weights test results, coverage and — most heavily — how recently rollback was actually exercised, because an untested rollback path is the difference between a five-minute incident and a five-hour one. Any open blocker overrides the arithmetic entirely.
Readiness score
score = 0.4 x test pass rate + 0.25 x coverage + 0.35 x rollback confidence, minus 25 per open blocker
Because it is the control that limits the impact of everything you failed to catch. A recently rehearsed rollback converts most release failures into brief blips.
The measurement should be. The decision benefits from human judgement, but the inputs should come from the pipeline rather than from a spreadsheet.
