Abstract

Requirements specification is an important part of the software, indeed the system, development process. It is critical that this effort be started early. This work suggests an early model for software developers to incorporate a systems viewpoint in their process. This model is an attempt to formalize an approach that will include a systematic representation of essentials of the external interface for software that is embedded within a larger system. The model is useful for early analysis of the software system and environment for such things as consistency, completeness, and safety.
