A software peer review, conducted by the peers of the software developer, to evaluate a software element. Although usually associated with code examination, this process is also applicable to the software requirements and software design. The major objectives of the walkthrough are to find defects (e.g., omissions, unwanted additions, and contradictions) in a specification and other products and to consider alternative functionality, performance objectives, or representations. Walkthroughs are credited to a well-known scientist by the name of Dr. Gerald Weinberg. He developed the theory of an egoless review. An egoless review (now called a walkthrough) is a review by peers of the author of the code.
