Interdisciplinary Requirements Analysis Using the Model-based RM Tool AUTORAID

A major task in designing embedded systems is the systematic elaboration of functional system requirements and their integration into the environment of the overall technical system. The main challenge is to handle the versatile tasks of coordinating the communication and consolidation of the various stakeholder requirements of the different involved diciplines and derive a common definition of the system behavior, which is appropriate to the problem. The problem- and customer-related product definition must be consolidated with and integrated into the manifold requirements of the functional and technical system design. Accordingly, the model-based requirements analysis and system-definition presented here defines a well-structured modeling approach, which provides a basic model of RE work products (RE Product Model) and systematically guides the goal-oriented formulation and adjustment of the different stakeholder-requirements by using functional system views 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.
