Abstract : The importance of the requirements stage in the development life cycle of software intensive systems is widely accepted. Associated with this is the need to use systematic methods to structure and control the requirements specification process. However, for large and complex systems the production of a requirements specification can be very costly. To gain the benefits of rigorous specification without repeatedly incurring high costs the Captain Naval Operational Command Systems (CNOCS) and the Admiralty Research Establishment (ARE) at Portsdown have pioneered a so called generic approach to the specification of requirements for surface ship command systems. In this way a specification is built up which can be tailored to any particular hull. The part of CNOCS which deals with Submarine requirements, CNOCS (SM), have recently begun to generate a generic user requirement for a Submarine Command System. The method they are using is similar to that being used by CNOCS for surface ships and is loosely based on the Controlled Requirements Expression (CORE) method.
