Description:

"We need better approaches to understanding and managing software requirements, and Dean provides them in this book. He draws ideas from three very useful intellectual pools: classical management practices, Agile methods, and lean product development. By combining the strengths of these three approaches, he has produced something that works better than any one in isolation." From the Foreword by Don Reinertsen, President of Reinertsen & Associates; author ofManaging the Design Factory; and leading expert on rapid product development Requirements gathering is a proven best practice for serious application development. However, requirements and Agile methods have rarely coexisted peacefully. For many enterprises considering Agile approaches, the absence of effective Agile requirements processes has been a showstopper. InAgile Software Requirements,Dean Leffingwell shows exactly how to create effective requirements in Agile environments. Part I presents the "big picture" of Agile requirements in the enterprise, and describes an overall process model for Agile requirements at the project team, program, and portfolio levels Part II describes a simple and lightweight, yet comprehensive, model that Agile project teams can use to manage requirements Part III shows how to develop Agile requirements for complex systems that require the cooperation of multiple teams Part IV guides enterprises in developing Agile requirements for ever-larger "systems of systems," application suites, and product portfolios This book will help you leverage the benefits of Agile without sacrificing the value of effective requirements gathering. Yours"ll find proven solutions you can apply right nowwhether yours"re a software executive, project/program manager, architect, team leader, developer, or tester.
