Continuous delivery

A DevOps maturity assessment scores observable capability rather than intent, and ends with a dated plan instead of a slide. This guide covers the four capability domains an assessment must cover, the five maturity levels and the evidence each one demands, the DORA and flow metrics worth reporting, a four-week assessment schedule, a scoring rubric that survives disagreement between teams, the quarter-by-quarter 12-month roadmap from stabilisation to a self-service platform, what the programme costs for a forty-engineer estate, and the mistakes that turn a useful baseline into an expensive filing exercise.
