Efficient Code Review in a Remote Work Environment: Establishing Team Ground Rules

As the work environment changed due to remote work and expanding team size, the existing in-person code review approach faced limitations that reduced productivity. In particular, in an environment where asynchronous communication has become important, the absence of clear standards led reviewers to give feedback from different perspectives, which lowered efficiency.

To address this, the team referred to the Google Engineering Practices Documentation to establish objective goals and criteria for code review. The main review items are as follows.

• Design: Reviewing scalability and traffic impact
• Functionality: Detecting exception cases and potential bugs
• Complexity: Managing code complexity for ease of maintenance
• Tests: Checking test coverage to ensure code reliability

In addition, to increase consistency in reviews, the team introduced a PR Template and established specific rules suited to the team's situation, aiming to improve code quality and turn 'my code' into 'our code'.
