Accelerate: The Science of Lean Software and DevOps: Building and Scaling High Performing Technology Organizations

“Do change management boards actually improve delivery performance?” (Spoiler alert: they do not; they are negatively correlated with tempo and stability.)

After 25 years of poiting this out, I am vindicated at last!!!

In short, approval by an external body (such as a manager or CAB) simply doesn’t work to increase the stability of production systems, measured by the time to restore service and change fail rate. However, it certainly slows things down. It is, in fact, worse than having no change approval process at all.
