Mean and median duration (days) of all closed reviews

This heat map compares the responsiveness of a repository to reviews (pull requests and merge requests). The light blue indicates review response times that are fastest; the red indicates the time slots with slowest response times. White boxes indicate time slots in which no reviews were closed. The minimum and maximum are determined by the pool of repositories within the report. For GitHub repositories, both accepted and declined pull requests are taking into account. For GitLab repositories, only the declined are being shown.

# Issues created/closed

Number of issues shows activity in the issue tracking system, usually including bug reports, feature requests, and other tasks that are tracked with issues (tickets). We measure, for each week, the number of issues that were opened (created) or closed during it. Not only the absolute numbers, but also the relationship between open and closed issues is important in this chart: if many more issues are consistently being opened than closed, the report is not dealing with all the new stuff that is entering the issue tracking system.
