Meaning
The duration between the start of development work and the successful deployment of that code to a production environment indicates delivery velocity. Tracking lead time for changes provides a clear signal of the maturity of a software delivery pipeline. The measurement begins when a commit enters the version control system and concludes when it functions in the live environment.
It stops applying once the software reaches a steady state of operation.
Cycle Duration
High lead time for changes often points to manual testing bottlenecks or complex approval chains. Automating these steps reduces the wait time.
Process Efficiency
A shorter window between code creation and delivery suggests a lean and responsive engineering organization. When lead time for changes remains consistent, the team can predict future output with greater accuracy. This predictability assists in planning and resource allocation for future development cycles.
Delivery Velocity
Rapid deployments allow for smaller batches of work which are easier to verify and roll back. Frequent use of lead time for changes as a performance indicator helps teams identify where the build process stalls. A low value indicates high capability and a robust infrastructure for continuous delivery.
The cost of calling a release ready too early often results in high failure rates rather than speed gains.
