Time and cost-savings
Code review performed at an early stage of the project can eliminate the need to fix problems at later stages, thus taking the load off QA engineers and accelerating project delivery. What’s more, correcting errors is much cheaper when you do it in good time, not when the solution is ready for production or falls into the hands of an end-user.
Developers can follow their own patterns and write code in a variety of manners, while by examining each other’s code, team members can draw on the pre-established standards. So the code review procedure can bridge diversities and make the code consistent throughout the overall company’s codebase.
Levelling up skills
Code review is about sharing knowledge, adopting experiences, and, consequently, learning. This practice allows the team to exchange information, ideas, and techniques, which is important not only for juniors but also for senior engineers who can get a teammate’s opinion and look at the problem from a completely different angle. As a result, developers can hone their skills and improve performance.
Code review implies close collaboration between developers and thus can assist in strengthening professional and personal team relationships. When performed in a friendly manner, code reviews can facilitate mutual support and enhance trust between coworkers. All this makes a great contribution to building a high-performing team.
Compliance with internal processes
Code review helps to verify the adherence to the company’s processes and workflows. By looking at their peers’ code, reviewers can check whether they are on the same page in terms of the project requirements and the way they should be implemented. Code review enables the team to document every detail to avoid misunderstanding or misinterpretation.
