Static program analysis is the analysis of computer software that is performed without actually executing programs — Wikipedia

The most important thing I have done as a programmer in recent years is to aggressively pursue static code analysis. Even more valuable than the hundreds of serious bugs I have prevented with it is the change in mindset about the way I view software reliability and code quality. — John Carmack (Creator of Doom)
