The Science of Lean Software and DevOps: Building and Scaling High Performing Technology Organizations by Gene Kim, Jez Humble, and Nicole Forsgren. Authors conducted an extensive survey among 23000 participants across 2000 organisations. High performing organisations have higher deployment frequency (multiple times per day), lower change lead time (less than an hour) and lower change failure rate (between 0-15%) compared with low performing organisations. They achieve this through coaching, sharing best security practices and providing relevant tools. It is inefficient to wait for security engineers to audit every single app rather than policing them and slowing them down.
