Processus de traitement et de formalisation des besoins métier d’un Système d’Information Décisionnel

During the analysis stage of requirements, directing the success of a BI project, several problems may be encountered include: poor collection of information, misunderstanding and the incompleteness of the needs, the multitude of profiles users and their contexts. These difficulties can negatively influence the process of analyzing the decision-making needs, and therefore the collective needs are often vague and not measurable. To address these problems properly assist future users in expressing their needs and guide analysts in addressing community needs, we propose a method of collecting needs in terms of goals by introducing the notion of context , then to establish patterns of association between these goals and finally, to extract, from informational purposes, the data decision. MOTS-CLÉS: Besoin métier, contexte, but, modèle d’association.
