Requirements engineering is a systematic approach to the development, allocation, transition, evolution and management of requirements for a system over the life-cycle. The system requirements process and CAE tools are an architectural product with an associated life cycle. Structured functional flow block diagramming is the base for this technology. Performance and functional requirements of a system are addressed for hardware, software, facilities, personnel and procedural data; and for all phases including acquisition, T&E, deployment, O&M and logistics. Emphasis is on command and control and tactical systems. The methodology to draw the block diagrams will be developed. There is also a system engineering data base that has records keyed to the diagram blocks containing descriptions, requirements and other engineering data. It will be able to store, correlate and retrieve data by using the facilities of a sophisticated relational data base management system (Oracle). Expert system techniques will enable user to effectively enter and retrieve requirements data. This requirements CAE tool will be user friendly and will provide cost-effective means to develop and manage system requirement.
