TL;DR: Accelerate
Nicole Forsgren, Jez Humble, and Gene Kim latest book Accelerate: Building and Scaling High Performing Technology Organizations [advertising] describes the factors that drive high-performing tech organizations, derived from the data that has been aggregated with the State of DevOps Report since 2014.
“Accelerate” [advertising] is a must-read book for anyone involved in building agile organizations and teams. It lays out a path to success based on a statistical analysis of data. It also puts an end to the popular narrative that ’becoming agile’ is somehow a fuzzy process. The data shows that there are patterns at all levels that successful agile organizations share.
In other words: becoming agile can be data-driven. (A hypothesis that I shared in How to Measure Agility of Organizations and Teams—The Results of the Agile Maturity Survey earlier.)
