Code Review Velocity

Code Review Quality Score evaluates the substantiveness of pull request reviews by weighting factors such as comment depth, suggestions made, files reviewed versus files changed, and time spent. It distinguishes meaningful reviews from rubber-stamp approvals. Higher scores correlate with fewer post-merge defects.

Lead Time for Changes measures the elapsed time from when a code change is committed to when it is successfully running in production. It is one of the four DORA metrics and a key indicator of delivery pipeline efficiency. Elite performers achieve lead times measured in hours rather than days or weeks.

Pull Request Bottleneck Analysis examines the stages of the PR lifecycle - authoring, review wait, review-in-progress, CI execution, and merge - to identify where delays accumulate. It transforms aggregate cycle time into an actionable breakdown that pinpoints specific process failures.

Team Collaboration Index quantifies the degree of cross-functional and cross-team interaction on GitHub, including cross-team code reviews, co-authored commits, discussion participation, and issue triage across repository boundaries. It measures whether knowledge and responsibility are shared or siloed.
