- Next question is how to approach a Code Review. Difficult to cover everything. I would make a start. When doing a code review, I start with static analysis results (for example, sonar). I spend 10 minutes getting an overview of components and/or layers (focusing on size and dependencies). Next I would pick up a unit test for a complex functionality. I feel unit tests are the best place to discover the dependencies and naming practices (I believe good names = 50% of maintainable code). If a programmer can write a simple and understandable unit test, he can definitely write good code. Next, I look for 4 principles of Simple Design. After this, there are 100 other things we can look for - You decide.

- First and Foremost - NO premature optimizations. Any optimization decision should be based on numbers or past experience. In Donald Knuth's paper "Structured Programming With GoTo Statements", he wrote: "Programmers waste enormous amounts of time thinking about, or worrying about, the speed of non critical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered. We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%."
