Deployment frequency

We settled on deployment frequency as a proxy for batch size since it is easy to measure and typically has low variability. By “deployment” we mean a software deployment to production or to an app store. A release (the changes that get deployed) will typically consist of multiple version control commits, unless the organization has achieved a single-piece flow where each commit can be released to production (a practice known as continuous deployment). — Accelerate: The Science of Lean Software and DevOps.
