Abstract:

The Software Cost Reduction SCR research project introduced a new approach to specifying requirements for real-time embedded systems. The principles were applied in the development of the Software Requirements of the A-7E Aircraft, as an example of the use of the approach. The system software requirements specification document comprises the first product in a series of products which the SCR methodology produces, The methodology is intended to be adaptable for various types of systems. Specification properties which it supports include 1 conciseness, 2 preciseness, 3 aids to completeness, 4 avoidance of redundancy, 5 descriptions of all externally visible behavior, 6 ease of change, 7 good reference tool, 8 record of fundamental assumptions which might otherwise be only implicit, 9 record of responses to error conditions, 10 specification of constraints on the system, and 11 separation of concerns that is, a division of the information into distinct, independent parts.
