Code review is the most formal way of code review. It is highly structured, and every participant must receive training first. Unlike peer review and walkthrough, the person who shows the code in the inspection is not the code writer. This will force the third party to learn and understand the code, and it is more likely to have different emphasis or understanding on the code interpretation in the audit meeting.

Other participants in the audit meeting acted as auditors. Each different role will review the code from different angles, such as users, testers or product support personnel. This helps to review the code from many aspects and find bugs. One of the auditors even needs to undertake reverse code review, that is, push from back to front to ensure the uniformity and integrity of coverage.

This is a short article describing the method of formal review of software code in the team. Peer review, walk-through and inspection are described and compared.
