This book offers a patterns-based approach to producing better use cases. Thedesign patterns approach has become popular because it allows softwarepractitioners to address recurring problems by applying a catalog of provensolutions. Use cases have gained widespread popularity because they allow asystem designer to determine how software will ultimately be "used" by thesystem's customer/end-user before the process of coding even begins. For allof their benefit and widespread acceptance, use cases are still misunderstood bya great number of professionals who could benefit from their effectivedeployment. This book marries the best of design patterns and use cases. Theauthors use the patterns approach to demystify use cases, and provide a provenframework for helping organizations build software more efficiently. The majorteaching points are supported by concrete, real-world examples.
