Eléments méthodologiques pour le développement des systèmes décisionnels dans un contexte de réutilisation (original) (raw)

The development of software facilitating decision taking is becoming more frequent, due to the growing need of reactivity and competitiveness within companies. Such software is called Decision Support Systems (DSS). However, 80% of decision making projects fail to satisfy user requirements, and 40% fail to help decision making 3. The recent works of methods bound to DSS define their schemes from the user requirements and the source systems. However, they can not represent all specificities of the DSS. Moreover, they rely on specific models representing only data, the dynamic aspect of DSS being largely ignored. Thus, none of these models is accepted neither by the researchers nor the practitioners.
