Conduct a merge-conflict root cause analysis

Merge Conflicts Are a Workflow Signal, Not a Git Problem

Teams treating merge conflicts as random friction miss the signal: recurring conflicts are a map of workflow problems — too-large PRs, unclear ownership, god files, refactors-in-flight. GitHub's developer productivity research and The Pragmatic Engineer's writing on engineering effectiveness both document the pattern: 30-day conflict inventories reliably surface 2-3 specific modules or workflow patterns that produce the majority of conflicts.

How the Conduct a merge-conflict root cause analysis Prompt Works

The prompt inventories 30 days of conflicts, performs pattern analysis to find the 3 files and PR pairs accounting for most conflicts, classifies root causes into five categories with matched interventions, and selects one ship-this-sprint move. The emphasis on specific modules and PR pairs — not vague "communication" — is what turns the review into an action plan.

When to Use It

• Merge conflicts are eating >2 hours/eng/week.
• A specific module is frequently at the center of conflicts.
• Two teams blame each other for the same area.
• A new EM wants a developer productivity baseline.
• A major refactor is in flight and conflict rate is spiking.

Common Pitfalls

• Blaming "communication". "We need to communicate better" is the generic retro bottom of the barrel. The data points to specific modules.
• Fixing the symptom. Adding a merge bot fixes resolution time, not the upstream PR-size or ownership issue.
• No follow-up measurement. Interventions without post-measurement don't prove anything. Re-measure at 30 days.
