What is the difference between a code walkthrough and a code review?

A code walkthrough is an educational meeting where the developer explains their code to help the team understand it. A code review is a more formal, critical evaluation where reviewers check for bugs, adherence to standards, and approve or request changes before merging. Walkthroughs often happen before reviews.

How long does a typical code walkthrough take?

A code walkthrough typically takes 30 minutes to an hour, depending on code complexity. Simple features might need 15–20 minutes, while large refactorings can take 90 minutes or more.

Who should attend a code walkthrough?

Team members who will work with the code, including developers, code reviewers, QA engineers, and sometimes tech leads. For critical features, you might invite the whole team.

Is a code walkthrough required before every pull request?

Not always. Walkthroughs are most useful for complex, high-risk, or large changes. Simple bug fixes or small refactorings may skip walkthroughs and go straight to asynchronous code review.

Can a code walkthrough be done asynchronously?

Walkthroughs are traditionally synchronous meetings, but teams sometimes record them or use detailed written explanations with code comments as asynchronous alternatives.

Don't say this

Handle with care. Do not confuse with code review. A walkthrough is a presentation/explanation; a review is a critical examination. Also avoid using as a verb without 'do' or 'conduct' — say 'conduct a code walkthrough,' not 'code walkthrough this.'

✕Can you code walkthrough this file?

✓Can you conduct/do a code walkthrough of this file?— Code walkthrough is a noun (a meeting or session), not a verb. Use 'conduct,' 'do,' or 'give' with it.

✕A code walkthrough is the same as a code review.

✓A code walkthrough explains the code; a code review evaluates and approves it.— These are different processes with different goals. A walkthrough is educational; a review is critical and formal.

✕We need to code walkthrough before the sprint ends.

✓We need to conduct a code walkthrough before the sprint ends.— Always use a verb like 'conduct,' 'do,' 'have,' or 'schedule' with the noun form.
