Per-period counts of PR activity, with two bars side by side: * **Opened** — PRs created in that period. Measures work started. * **Merged / Closed** — stacked bar of PRs that exited the queue. Measures work shipped vs dropped. Click a column to jump to the PRs opened, merged, or closed in that period. ### Why it matters Throughput is the raw delivery rate. Compared against opens, it surfaces whether the team is keeping up with incoming work or building up WIP. A rising close rate (vs merge) can hint at abandoned branches or scope churn. ### Insights * Are we shipping faster than we're opening new work, or falling behind? * Are closed-without-merge PRs growing? That usually means scope churn or abandoned branches. * Did a process change actually lift throughput, or just shift where the work sits? ### How the chart is built * **Opened** counts PRs by **when they were created** in the selected range. * **Merged** counts PRs by **when they were merged** in the range. * **Closed (without merge)** counts PRs that were closed in the range but never merged. * Time buckets (daily, weekly, etc.) always appear for the full date range you picked; a bucket with no activity shows as zero. ## See Also
