From the reviews:
“The book details a useful taxonomy for the successful specification, classification, and documentation of project functional requirements. ... Although the author designed the book to be a useful textbook for students, it should also be useful for project managers who need to understand that quality results don’t just happen; they must be designed, and a successful design is built on a thorough and detailed analysis of requirements and specifications.” (David Bruce Henderson, Computing Reviews, June, 2013)
