Code Review Process,
as a gantt chart.
A Gantt chart template mapping every stage of the code review lifecycle—from PR open to merge—ideal for engineering leads and dev teams tracking review workflows.
About this
specimen.
A code review process Gantt chart visualizes the full timeline of a pull request, from the moment a developer opens a PR through automated checks, peer review rounds, requested changes, approvals, and final merge. Each phase appears as a horizontal bar spanning its expected duration, making it easy to see how long reviews sit idle, where bottlenecks form, and how parallel activities—like CI/CD pipeline runs and human review—overlap. Engineering managers, tech leads, and Agile teams use this template to set realistic review SLAs, communicate expectations to stakeholders, and identify workflow inefficiencies before they slow down a release.
## When to Use This Template
This template is most valuable when your team is experiencing slow merge times, inconsistent review turnaround, or unclear handoff points between reviewers. Use it during sprint planning to allocate review capacity alongside feature work, or during retrospectives to compare planned versus actual review durations. It is equally useful when onboarding new contributors who need a clear picture of what happens after they submit a PR—covering stages like automated linting, security scanning, first-pass review, revision cycles, and final approval gates before merge.
## Common Mistakes to Avoid
One of the most frequent errors when building a code review Gantt chart is treating the entire review as a single task rather than breaking it into discrete, measurable phases. Collapsing "review" into one bar hides the reality that automated checks, initial feedback, author revisions, and re-review are separate activities with different owners and durations. Another common mistake is ignoring wait time—the idle periods when a PR is open but no one is actively working on it. These gaps are often the biggest contributors to slow cycle times and should be represented explicitly. Finally, avoid setting bar durations based on best-case scenarios; use historical data or team averages to make the chart actionable rather than aspirational. A Gantt chart that reflects real workflow patterns becomes a living planning tool, not just a decorative diagram.

Common
questions.
- 01What phases should a code review Gantt chart include?
- A thorough code review Gantt chart should include PR creation, automated CI/CD checks, initial reviewer assignment, first-pass review, author revision period, re-review, approval, and merge. Adding wait-time buffers between phases gives a more accurate picture of total cycle time.
- 02How do I estimate durations for each code review stage?
- Pull historical data from your version control platform (GitHub, GitLab, Bitbucket) to calculate average time spent in each phase. If data is unavailable, start with team estimates and refine the chart after a few sprints of observation.
- 03Can this Gantt chart template be used for multiple PRs at once?
- Yes. You can add a row per pull request or per reviewer to track concurrent reviews. This helps managers spot when reviewers are overloaded and when review queues are likely to create merge bottlenecks.
- 04How is a code review Gantt chart different from a simple checklist?
- A checklist confirms that steps were completed but provides no timing or dependency information. A Gantt chart shows how long each phase takes, which phases overlap, and where delays occur—making it a far more powerful tool for process improvement and capacity planning.
