Documenter l'alignement d'un ED avec la stratégie d'entreprise en vue de mieux satisfaire les exigences des décideurs

Documenting strategy is necessary to improve the ability of decision support systems, in particular Data Warehouses (DW), to satisfy the fundamental requirements of the enterprise and its chief executives. However, very few requirements-driven approaches have been proposed so far to design DW and even less to document enterprises' strategic objectives with a sufficient level of formality to do so. However, we believe that to align DWs to the enterprise's strategic requirements would allow to develop DW delivering more reliable support to strategic decision-making. Aligning the enterprise's strategy and DWs necessitates to specify both the DW requirements and the enterprise's strategy. This paper presents the CADWA approach that allows (i) to model the strategic objectives that must be taken into account in the DW and (ii) a way to plan and control its strategic alignment. The originality of our approach stands in the use of a unique modelling technique. The proposed approach is applied to the study of a Japanese retail company.
