  This book describes how to gather and define software requirements using a process based on use cases. It shows systems analysts and designers how use cases can provide solutions to the most challenging requirements issues, resulting in effective, quality systems that meet the needs of users.

  Use Cases, Second Edition: Requirements in Context describes a three-step method for establishing requirements-an iterative process that produces increasingly refined requirements. Drawing on their extensive, real-world experience, the authors offer a wealth of advice on use-case driven lifecycles, planning for change, and keeping on track. In addition, they include numerous detailed examples to illustrate practical applications.

  This second edition incorporates the many advancements in use case methodology that have occurred over the past few years. Specifically, this new edition features major changes to the methodology's iterations, and the section on management reflects the faster-paced, more chaordic software lifecycles prominent today. In addition, the authors have included a new chapter on use case traceability issues and have revised the appendixes to show more clearly how use cases evolve.

  The book opens with a brief introduction to use cases and the Unified Modeling Language (UML). It explains how use cases reduce the incidence of duplicate and inconsistent requirements, and how they facilitate the documentation process and communication among stakeholders.

  The book shows you how to:

  • Describe the context of relationships and interactions between actors and applications using use case diagrams and scenarios
  • Specify functional and nonfunctional requirements
  • Create the candidate use case list
  • Break out detailed use cases and add detail to use case diagrams
  • Add triggers, preconditions, basic course of events, and exceptions to use cases
  • Manage the iterative/incremental use case driven project lifecycle
  • Trace back to use cases, nonfunctionals, and business rules
  • Avoid classic mistakes and pitfalls

  The book also highlights numerous currently available tools, including use case name filters, the context matrix, user interface requirements, and the authors' own hierarchy killer.

  Software developers are increasingly recognizing the value of careful up-front requirements gathering in enhanced efficiency and reduced software defects. The best way to gather requirements accurately and precisely is with use cases and UML -- and this book walks you through the entire process, step-by-step. Both an excellent tutorial and a handy reference, Use Cases: Requirements in Context begins with a detailed overview of requirements gathering, its key challenges, and why traditional approaches often fail. Next, understand the key concepts underlying use cases; use case diagrams and scenarios; relationships and interactions; and the role of use cases in each major type of software development project. Review the four steps of the requirements gathering process, from problem statement through prototype; then walk through each iteration of the use case, step-by-step. The book includes insightful coverage of managing the requirements gathering process, building teams, and assuring quality -- plus a full chapter on the classic mistakes made in requirements gathering, and how to avoid them. For all systems analysts, project managers, and software engineers.
