Structured Requirements and a Systems Engineering Environment

A requirements management system forms the natural framework for a systems engineering environment (SEE). Requirements control the whole system, and cover the whole lifecycle. Requirements are the means of communication between systems engineers and all the specialist disciplines. A SEE based on requirements allows control at any required level of detail. This approach allows an incremental approach to developing a complete project toolset. This paper defines a SEE, in relationship to a commercial requirements management tool, DOORS. Systems engineering covers systems-level tasks, such as the creation of requirements, technical management, and verification management. Tools used for specialist tasks remain outside the SEE although it will need to communicate with those. © 1994 The Authors.
