Setting Up Code Review Process for Development Team

Code review without a clearly defined process becomes a bottleneck: PRs hang for 3 days, reviewers write subjective comments, the author doesn't understand what's urgent and what isn't. Result—accumulated WIP and team demotivation.

Process Elements

PR template—structured description of changes that the author fills in when opening a PR:

<!-- .github/pull_request_template.md -->
## What was done
<!-- Brief description of changes -->

## Why
<!-- Link to issue or context -->
Closes #ISSUE_NUMBER

## How to test
<!-- Steps to verify -->
1.
2.

## Checklist
- [ ] Tests added / updated
- [ ] Documentation updated
- [ ] No console.log and debug code
- [ ] No hardcoded secrets

CODEOWNERS—automatic reviewer assignment by files:

# .github/CODEOWNERS
# Global reviewer
*                   @tech-lead

# Backend—only backend developers
/src/api/           @backend-team
/database/          @backend-team

# Infrastructure—only DevOps
/.github/           @devops-team
/docker/            @devops-team

Rules for Reviewers

Comment levels—so the author understands priority:

  • [blocker]—merge is impossible until fixed. Bug, vulnerability, architecture violation.
  • [suggestion]—improvement, but not required. Author decides.
  • [question]—request to explain the solution. Doesn't require changes.
  • [nit]—minor detail (typo, formatting). Doesn't block.

Time agreement: reviewer must process PR within 1 business day. If they can't make it—they write when they can or ask another reviewer. PR should not hang without response for more than a day.

Automated Checks Before Review

Reviewers should not waste time on things that can be automated:

# .github/workflows/pr-checks.yml
name: PR Checks
on: [pull_request]
jobs:
  lint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - run: npm ci
      - run: npm run lint
      - run: npm run type-check
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - run: npm ci && npm test

Linter catches style, tests catch regressions—reviewer focuses on architecture and logic.

Process Metrics

Track through GitHub Insights or LinearB:

  • Time to first review—how long PR waits for the first comment
  • Time to merge—from opening to merge
  • PR size—large PRs (>400 lines) are reviewed worse

Goal: average time to merge < 24 hours, 80% of PRs < 200 lines.

Timeline

Writing PR template, setting up CODEOWNERS, automated checks, and documenting the process for the team—1–2 days.
