A Cohesive Design Based Management of Embedded Systems Requirements

Abstract:

The Automobile Manufacturers and their Suppliers are now moving towards system-oriented industry best practices. However, to be effective and used as management tools rather than process constraints, such methods and associated tools must be agile and flexible in order to keep Automotive EE teams involved and synchronized. Definition of good requirements at system level is one of these best practices, but benefits are secured only when all actors are orienting and justifying their work in relation to these requirements. Innovative technologies and methods allow to design the requirements in both textual and graphical ways, using model-based implementations with automatic code and test generations.
To have all teams playing the game of requirements management and traceability is a challenge; the key is in a Process and Tool combination that can allow to get the information where it is available and relevant, and to make this information available for other teams and for management, with minimum extra-work. This paper pertains to a state-of-the-art technology developed with the aerospace industry and now deployed in the automotive industry; it also outlines elements of a visionary approach maturing in the Automotive EE segment which could well apply to other fields in the future.
