Mean Lead Time for Changes (MLTC) is a crucial DevOps metric that tracks the average duration from when a code change is committed after its successful deployment in production. This metric is essential for evaluating the efficiency and agility of a development team. Here’s how you can calculate MLTC:Identify start and end points. The start point is when a code change is committed to the repository. The endpoint is when the code is deployed and operational in production.
Measure individual lead times. Calculate the time difference between the start and end points for each change.
Compute the average. Add up all the individual lead times over a specific period (e.g., a week or a month) and divide this total by the number of changes.By analyzing this metric, teams can gain valuable insights into the efficiency of their development processes, allowing them to make informed adjustments to enhance speed and responsiveness to changes.
