Requirements management has proven itself to be an enormous potential for the optimization of development projects throughout the last few years especially in the climate of an increasingly competitive market This book focuses on the interfaces of requirements management to the other disciplines of systems engineering for example project management change management and configuration and version management. It provides an introduction into requirements management and requirements development along with a short sketch of systems engineering. Coverage also explains the necessary inputs and resulting outputs of requirements management. Using these flows of information the book shows how requirements management can support and optimize the other project disciplines and how very important it is for all areas of development.
