Dean Leffingwell, Don Widrig · International Linear Collider · 2003
From the Publisher: Despite the wealth of development knowledge, experience, and tools available today, a substantial percentage of software projects fail, often because requirements are not correctly determined and defined at the outset, or are not managed correctly as the project unfolds. This Second Edition of the popular text Managing Software Requirements focuses on this critical cause of failure and offers a practical, proven approach to building systems that meet customers' needs on time and within budget. Using an approachable style, their own war stories and a comprehensive case study, the authors show how analysts and developers can effectively identify requirements by applying a variety of techniques, centered on the power of use cases. The book illustrates proven techniques for determining, implementing, and validating requirements. It describes six vital Team Skills for managing requirements throughout the lifecycle of a project: Analyzing the Problem, Understanding User Needs, Defining the System, Managing Scope, Refining the System Definition, and Building the Right System. Managing Software Requirements specifically addresses the ongoing challenge of managing change and describes a process for assuring that project scope is successfully defined and agreed upon by all stakeholders. Topics covered include: The five steps in problem analysis Business modeling and system engineering Techniques for eliciting requirements from customers and stakeholders Establishing and managing project scope Applying and refining use cases Product management Transitioning from requirements to design andimplementation Transitioning from use cases to test cases Agile requirements methods
