Code Review Process Flowchart Template

A code review process flowchart visualizes the complete lifecycle of a pull request, from the moment a developer opens it to the final merge into the main branch. This template captures every critical decision point and handoff: automated CI checks, reviewer assignment, feedback cycles, approval gates, and merge conditions. By laying out each step in a clear, logical sequence, the diagram makes implicit team conventions explicit and gives every contributor a shared reference for how code moves through the review pipeline.

## When to Use This Template

This flowchart is especially valuable when onboarding new engineers, auditing an existing review process for bottlenecks, or aligning distributed teams on a consistent workflow. If your team frequently debates whether a PR needs one approval or two, what happens after a "request changes" response, or who is responsible for resolving merge conflicts, a documented flowchart eliminates that ambiguity. It also serves as a living artifact during retrospectives, giving teams a concrete starting point for process improvement conversations rather than relying on memory or tribal knowledge.

## Common Mistakes to Avoid

One of the most frequent errors when diagramming a code review process is oversimplifying the feedback loop. Many teams draw a straight line from "review" to "approve," omitting the iterative cycle of comments, revisions, and re-reviews that actually occurs. Make sure your flowchart includes a clear loop back to the author when changes are requested. Another common mistake is leaving out automated steps such as linting, test runs, or security scans, which are often prerequisites before human review even begins. Omitting these creates a diagram that does not reflect reality and can mislead new team members. Finally, avoid ambiguous decision diamonds. Each branching point should have clearly labeled outcomes, typically "Yes" and "No" or specific status labels like "Approved," "Changes Requested," or "CI Failed," so there is never confusion about which path to follow.
