Defect Rate

The percentage of merged pull requests that address defects.


We determine that a PR is addressing a defect by looking at its title and looking for the presence of a set of keywords, specifically any word that begins with:

  • fix

  • revert

  • bug

  • repair

Thus, it will match things like "reverts", "bugfix", "fixes", "repairs" etc. Because we're looking for words that begin with these keywords, we'll match for "fixes", but not "prefix".

  • Defect Rate is only calculated for merged PRs.

  • Defect Rate only analyzes PR titles, and not commit messages or branch names.
