Accelerate book
The DORA research distilled — what predicts software delivery performance, with empirical backing.
The DORA research distilled — what predicts software delivery performance, with empirical backing.
why it matters
Until Accelerate, debates about 'agile vs not' or 'continuous deployment vs not' were vibes-based. This book brought multi-year survey data showing that high performers cluster on four metrics, and that the practices predicting those metrics aren't religious — they're measurable. Reframed software delivery as something you can evaluate empirically.
key ideas
- Four DORA metrics: deployment frequency, lead time for changes, change failure rate, mean time to recovery
- High performers deploy more often AND have fewer failures — speed and stability aren't opposed
- Trunk-based development, CI, automated testing, and feature flags are the practices that move the metrics
- Loosely coupled architecture predicts delivery performance more strongly than any technology choice
- Burnout, deployment pain, and culture are measurable and predict performance
memorable framings
- Speed without quality is rework
- 'You build it, you run it' isn't ideology — it's a structural alignment
who should read it
Engineering leaders making the case for investment in delivery infrastructure. Citation gold when arguing for CI, trunk-based dev, or platform investment.
