近年来,需求管理作为一种高层次的系统行为,逐渐成为软件项目管理的一个重要而活跃的领域,并且得到业界的普遍重视。需求是项目的源头,需求管理则是对需求全生命周期的管理,源于初始需求提出,经过分析确认和产品派生,止于需求验证,形成一个完整闭环。从这个层面来看,需求管理是项目过程中的工作,贯穿项目始终。 In recent years, demand management, as a high-level system behavior, has gradually become an important and active area of ​​software project management, and has received widespread attention in the industry. Demand is the source of the project. Demand management is the management of the entire life cycle of the demand. It originates from the initial demand. After analysis and confirmation and product derivation, it stops at the requirement verification and forms a complete closed loop. From this perspective, requirements management is the work in the project process and it is always through the project.
