The need for an integrated enterprise-wide set of management information pronounced Data Warehousing the ‘hot topic’ of the early-to-mid 1990’s, however, it became unfashionable through the mid-to-late 1990s, with the approach of Y2K and the widespread implementation of ERP (Enterprise Resource Planning) systems. However, in recent times, the re-emergence of Data Warehousing, coupled with ERP implementations, to address the limitations and unrealised benefits of ERP systems in the area of reporting, provides researchers and managers with new challenges. This paper lays the foundation for a model of organisational prerequisites for enterprise-wide integration projects. The model is aimed at the ‘Intelligence’ phase of managerial decision making for such projects and should help managers assess their organisation’s readiness for ERP and data warehousing projects .The main objective of the paper is to present a literature-based model which lists the key prerequisites that organisations should assess prior to undertaking these expensive projects.
