When I first picked up this book, my initial reaction was "Great, just what the world needs, yet another book about use cases." Then I noticed the subtitle, Working Smart to Deliver Quality, and thought I should invest a few minutes looking it over. I'm glad that I did. Perusing the table of contents, I noticed sections entitled "Planning the Length of Iterations and Number of Use Cases in Distributed Software Development", "Setting a Failure Intensity Objective", and "Savings from Avoiding Cost of Unnecessary Development" and realized that this was more than just another use case book. Denney provides real world advice, based on his more than 25 years of experience in software development, for how to apply use cases effectively in practice. For anyone wanting to improve their use case writing skills, his insights on preconditions, postconditions, and invariants is well worth the investment in this book. For project managers, Denney's advice for estimating and scheduling based on use cases is both practical and insightful.
