Poor requirements management is one of the top five contributors to poor project performance. In extreme, safety critical or emergency-relief situations, failure to satisfy the real needs of the project stakeholders may well lead directly to loss of life or human suffering; other, more mundane, projects can also be severely compromised. Dr Mario Kossmann's Requirements Management looks at the process from the perspectives of both Program and Project Management and Systems Engineering, showing the crucial role of RM in both contexts. The author puts great emphasis on the human aspects of any project, which is also significant given that over-emphasis on technical or technological aspects at the expense of the human side is another major source of project shortfalls. The book offers illustrated examples of systems of different levels of complexity (one simple system, one complex, and one highly complex system) to help you categorize your own system and enable you to select the right level of formality, a suitable organization and a set of techniques and tools to carry out your requirements work. It includes a series of comprehensive checklists which can be used immediately to improve urgent requirements aspects. This is a practical and realistic guide to requirements management that provides a flexible, hands-on and innovative approach to developing and managing program, project and system requirements at different levels of complexity; read it and use the advice offered to ensure your projects can actually deliver, first time, without the need for costly and time-consuming rework.
