Code Review Process,
as a user journey.

A code review user journey diagram visualizes the end-to-end experience of a developer submitting a pull request and seeing it through to a successful merge. This template maps each touchpoint — opening the PR, requesting reviewers, receiving feedback, pushing revisions, resolving conversations, and finally merging — while capturing the emotions, pain points, and actions of every participant involved. Unlike a simple flowchart, a user journey format layers in the human experience: how a developer feels waiting for a first review, where reviewers lose context, and which handoff moments create the most friction. The result is a shared artifact that makes invisible bottlenecks visible to the entire team.

## When to Use This Template

This template is especially valuable when your team is experiencing slow cycle times, inconsistent review quality, or recurring miscommunication between authors and reviewers. Use it during engineering retrospectives to audit where PRs stall, or when onboarding new contributors who need to understand the full review workflow. Product managers and engineering managers can use the completed diagram to align on service-level expectations — for example, defining a target time-to-first-review — while senior engineers can use it to identify steps that could be automated or streamlined with tooling like CI checks, linting gates, or auto-assignment rules.

## Common Mistakes to Avoid

One of the most frequent mistakes when building this diagram is focusing only on the "happy path" — the smooth, frictionless PR that gets approved on the first pass. Real value comes from mapping the revision loop: what happens after a reviewer requests changes, how the author is notified, and how follow-up reviews are triggered. Another common error is omitting non-author participants. Reviewers, tech leads, and even automated bots (CI/CD pipelines, linters) are actors in this journey and should be represented in their own swim lanes or phases. Finally, avoid treating all PRs as identical. Consider creating separate journey variants for small bug fixes versus large feature branches, since the emotional arc and number of touchpoints differ significantly. A well-constructed code review journey map becomes a living document — revisit and update it as your team's process evolves.
