I used to internally cringe when people mentioned code review – where developers check each other’s work after it has been implemented and suggest improvements. The tests were in place, QA had signed off, the product owner was happy. Surely by definition code review was just the practice of looking for problems.
If that sums up how you feel about code review, then sorry — you’re going to hate this. Nowadays, I think peer review is one of the most powerful devices for projecting best practice in a product, a team, a company and beyond. Notice I call it peer review rather than code review. To me, there are some important differences. Code review is good – it raises standards and awareness of standards. But peer review is more powerful still.
