Des buts à la modélisation système : une approche de modélisation des exigences centrée utilisateur

One of the existing problems in requirement engineering consists in arriving to capture final user requirements as well as possible. But it is clear that engineering methods such as goal-oriented models or system-oriented requirement diagrams such as SYSML are sometimes too hard for end-users. In this paper we define a systematic process allowing ennd-users to specify requirements using cognitive models such as mind maps. Then, those models are transformed into KAOS models, then in SYSML models, using model transformation rules. This approach is applied to an industrial case application.
