  "definition": "1. An interdisciplinary function that mediates between the domains of the acquirer and supplier to establish and maintain the requirements to be met by the system, software, or service of interest.\n\n2. A series of successive decomposition and derivation actions beginning with stakeholder requirements and moving through high-level design requirements to low-level design requirements to the implementation of the design. During requirements engineering, several requirements baselines are defined. These baselines include: a functional baseline that provides the basis for contracting and controlling the system design; an allocated baseline that provides performance requirements for each configuration item of the system; and a product baseline that provides a detailed design specification for system elements.",
