How Long Does Code Review Take? In practice, a review of 200-400 LOC over 60 to 90 minutes should yield 70-90% defect discovery. So, if 10 defects existed in the code, a properly conducted review would find between seven and nine of them.

Are code reviews worth it? Talk with developers who use a tool for code review and you’ll find they are much happier than their counterparts who aren’t. Most happy, however, are the developer managers that can use the tool to measure the team’s quality and improvements. For all of them, the time spent is well worth it.

What happens during code review? Code Review, or Peer Code Review, is the act of consciously and systematically convening with one’s fellow programmers to check each other’s code for mistakes, and has been repeatedly shown to accelerate and streamline the process of software development like few other practices can.

How code review is done for your code? Code review is a software quality assurance process in which software’s source code is analyzed manually by a team or by using an automated code review tool. The motive is purely, to find bugs, resolve errors, and for most times, improving code quality.
