Verification · Feedback and evaluation · Missed bug analysis
Cause clustering
Cluster root causes to find the systematic gaps.
How to build it
- Gather the root-cause notes for all escaped bugs from the period.
- Cluster the notes by cause, such as a missing test, an unclear rule or a skipped file.
- Rank the clusters by count to pick the gaps to fix first.
Signals in a repository
- A root-cause category field on each bug record.
- A summary file that lists clusters of missed-bug causes with counts.
In practice
No scanned repository runs a tool for this check. The steps above are the only guidance.
