1 We spent a significant amount of time reviewing code. In fact we spend on average 5 hours per week reviewing code or 12.5% of our week looking at code.
2As a developer, spending more than a day a week reviewing code doesn’t correlate with improvements in perceived code quality OR in more time shipping new features (as opposed with fixing bugs or paying back tech debt).
3 45% of developers say that ‘Lack of Time’ is the real obstacle to reviewing code while 34% say ‘Pressure to Ship’.
4 72% of developers say that their code reviews are blocking (don’t ship a line of code without being reviewed).
5 66% of developers require 1 person to approve their pull requests. 25% require 2 people. Less than 5% require more than 2.
6 53% of people monitor code coverage but 65% don’t have a minimum threshold of code coverage to approve a pull request.
7 29% of developers say the biggest problem in their project is “Workload” while VPs of Eng and Directors say “Delivery speed”. The third biggest problem for developers is “Management”
8Regarding who gets to review code, having everyone in the team do it is the most common practice. Other alternatives are having owners of projects or modules or having senior developers review most of the code.
9Stricter code reviews lead to less time fixing bugs and more time delivering new features. Less strict code reviewers spend 31% of their time fixing bugs whereas stricter reviewers spend 24%. Regarding time focusing on new features: 43% and 54% corresponding.
10Developers spend 45% of their time fixing bugs or addressing technical debt vs of building new features.
