Carefully watching for such tiny increments during code reviews and preventing them from surviving and propagating is IMO critical to a project’s long term success, even if simplicity isn’t considered an important factor in a project’s long-term success, in mainstream programmer culture. I actually have slightly different measuring sticks for productive and test code: Code review (sometimes referred to as peer review) is a software quality assurance activity in which one or several people check a program mainly by viewing and reading parts of its source code, and they do so after implementation or as an interruption of implementation.At least one of the persons must not be the code's author. This imposes some constraints, and establishes some assumptions: Code must be working - even though we often could help people with broken code, it is not in scope here because Stack Overflow is the place for specific programming questions. For example, if the code is related to Orders, is it in the Order Service? Don’t Repeat Yourself is the principle that any code in your program should only be written once, and never duplicated. great information for improved programming.
