How to Set Up a Code Review Process

Reviews that catch real problems - without becoming a bottleneck or a politics game.

Code review is the highest-leverage quality practice a team can have. It's also the easiest to get wrong: reviews that take 3 days, nitpicks that block ships, and approvals that nobody actually reads. This guide covers the structure that makes reviews fast, useful, and genuinely educational.

No fluff. Production-grade answers from engineers who build this every day.

What Makes a Code Review Actually Useful?

The goal of a code review is not to catch every bug - automated tests do that. The goal is knowledge transfer, architectural alignment, and catching things the author was too close to see. A useful review asks: does this fit the codebase patterns? Are there edge cases the author missed? Is the abstraction appropriate? It does not ask: why didn't you use a semicolon here?

At Valletta Software, we focus on:

PR size: max 400 lines of meaningful change - anything bigger gets split

PR description: what changed why how to test screenshots if UI

Review turnaround SLA: first response within 4 business hours - not 3 days

Reviewer rotation: 2 reviewers per PR one domain expert plus one fresh eye

Review checklist: logic tests naming security performance docs update

Blocking vs non-blocking: distinguish must fix from consider this in comments

Author etiquette: respond to all comments mark resolved no silent merges

The Tooling That Makes Reviews Smooth

Good process plus right tooling equals reviews that ship not reviews that block.

We give you more than just people. We give you top performers who drive results.

GitHub Pull Requests or GitLab MRs - with protected main branch required reviews

PR templates - checklist in the description enforced by CODEOWNERS

Danger.js or reviewdog - automated checks before human review (lint test size)
