Most developers have the best intentions, and usually there is nothing wrong with their code. Our code reviews provide a sanity check to make sure that what they write meets the guidelines and best practices for doing WordPress plugin and theme development. We find that code review improves the workflow at most agencies in a few ways.
First and foremost, people tend to write better when they know that someone will be reading it. People who write code that they know will be reviewed tend to develop better habits, making them more effective, better programmers. Secondly, fewer bugs make it to production. That means that your clients are happier, your support workload is reduced, and ultimately, you have to say “I’m sorry” less. Lastly, it gives you an understanding of how well your employees are performing in their job. Code review is an easy way to gather information about how productive your developers are, which often leads to a more productive staff.
