A COHESIVE DESIGN BASED MANAGEMENT OF EMBEDDED SYSTEMS REQUIREMENTS

摘要

The Automobile Manufacturers and their Suppliers are now moving towardssystem-oriented industry best practices. However, to be effective and used as managementtools rather than process constraints, such methods and associated tools must be agile andflexible 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 arcsecured only when all actors are orienting and justifying their work in relation to theserequirements.Innovative technologies and methods allow to design the requirements in both textual andgraphical ways, using model-based implementations with automatic code and test generations.To have all teams playing the game of requirements management and traccability is achallenge; the key is in a Process and Tool combination that can allow to get the informationwhere it is available and relevant, and to make this information available for other teams andfor management, with minimum extra-work.This paper pertains to a state-of-the-art technology developed with the aerospace industry andnow deployed in the automotive industry; it also outlines elements of a visionary approachmaturing in the Automotive EE segment which could well apply to the aerospace field in thefuture.
