Negative Positive
Title: Techniques may be useful but be cautious of opinions
Review: Dr. Beizer appears to use the medium of a textbook on black box testing, which is the domain of testers without knowledge of source code or design, to promote the opinion that independent testing is useless except to protect the independent tester. Later, he admits that 80 percent of an average product lifecycle is maintenance phase, which he admits is an appropriate use of independent testers, as he admits also their use for specialized testing tools such as performance tools. His techniques may be effective but an executive level review of this book could be dangerous to the future of quality software engineering practices.
