Features, Churn, and Refactor

DEFINITION

Pull requests are categorized into three types: features, churn, and refactor. While a balance of churn and refactor is needed to maintain and improve quality, teams should optimize for shipping more features on a sustained, long-term basis.

HOW IT'S MEASURED

The code changed in each feature is categorized as follows:

Features, churn, and refactor are then calculated as the average breakdown across pull requests multiplied by the total number of pull requests merged during that time period.
