Use Cases: Requirements in Context

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.
