Review of Patterns for Effective Use Cases (The Agile Software Development Series) (Paperback)

This book attempts to take use cases to a higher level of science and in part succeed. Its plus points are discussions on management of use cases and the processes a team goes through in completing the creation / validation cycle. There's a lot of good sense here. Some of the patterns are useful. However, there's also a lot of regurgitation from various other texts and papers, some written by the authors themselves. And some key aspects are missing, aspects that are really important to industry and others that have concerned academia. Industry is not too worried about how to name use cases these days; that's easy. They want to be able to estimate how long it will take to build the system from use case points, for instance, or how to achieve forward traceability to the design and maintain traceability back to the requirements and business strategies (not the same thing exactly as the use case goal - which typically is not to stuff up and to make the principal actor happy). Academics are concerned too with effort estimation, with grammar and consistency checking, with dependencies and product lines, and non-functional requirements and whether use cases are at all to do with requirements in the first place and what they are no good for. Not whether we can build a little online booking web site - we can already do that. Though the book does not set out to answer these difficult questions, in its 200-odd pages, it ought to have, since this is what we really want to know about. So, though the book is excellent on what it does address, there's a lot of over kill in this. What's missing is what it does not address - all the hard problems we really need answers to.

Product Description
First book to specifically address use cases with the proven and popular development concept of patterns. Guidelines are included for readers to measure the quality of their use cases. Softcover.

From the Back Cover

Use cases have become an integral part of modeling software requirements, but many software developers are discovering that writing effective use cases is more difficult than they had anticipated. An understanding of the basic principles of use cases is not enough. Software developers need a source of objective criteria by which to judge quality and effectiveness.

Patterns for Effective Use Cases provides this set of objective criteria. Written by experienced use case practitioners, this book fills a critical information gap by presenting a pattern language that contains over thirty patterns, providing simple, elegant, and proven solutions to the most common problems in use case development. These patterns distill and define the properties and characteristics of quality use cases. As such, they facilitate the development of original use cases and provide a diagnostic tool for evaluating existing ones.

The book opens with a review of use cases and pattern fundamentals, along with a discussion of the requirements-gathering team. These patterns address the use case development process, the internal structure of use cases, and the relationships among use cases within the system as a whole. Examples of patterns include:

• BreadthBeforeDepth
• VisibleBoundary
• EverUnfoldingStory
• IntentionRevealingName
• PreciseAndReadable
• LeveledSteps
• InterruptsAsExtensions
• RedistributeTheWealth

Each pattern discussion includes at least one example demonstrating its real-world application, highlighting both the benefits of using the pattern and the consequences of not doing so. In addition, the book presents guidelines for the effective use of UML with relevant patterns.

Anyone involved in use case writing or requirements gathering will find Patterns for Effective Use Cases an indispensable handbook and reference.
