A Model-Based Approach To Requirements Analysis

A major task in designing embedded systems is the systematic elaboration of functional system requirements and their integration into the environment of the complete technical system. The main challenge is to handle the versatile tasks of coordinating a definition of behavior, which is appropriate to the problem. The problem- and design-specifications of the customer related product definition have to be adjusted with and integrated into the manifold requirements of the technical system design. Accordingly, the model-based requirements analysis and system-definition presented here defines a well-structured modeling approach, which systematically aids the goal-oriented formulation and adjustment of the different stakeholder-requirements with the aid of views onto the system and descriptive specification techniques. Thus it allows a clear specification of a consistent and complete system design. The central steps of this approach are implemented in a requirements management (RM) tool prototype called AutoRAID
