The goal of the research was to determine which strategies promote success on DSS projects designed to enable supply chain management (SCM).

They must be able to analyze, interpret, and act on complex data. These analytical skills were found to be significantly more important for DSS users to have than ERP users (p < 0.05). Intelligent SCM systems must include "what if' functionality and allow users to evaluate multiple business scenarios before acting. The "small releases" systems development methodology (i.e., phased approach to implementing business functionality was found to be more appropriate for DSS than ERP projects (p < 0.05).

Many strategies, which are traditionally considered administrative in nature, were found to be more important for ERP systems projects (p< 0.05). Utilizing cross-functional project teams, ensuring user participation, securing top-management support, and providing extensive user training were all found to be significantly more important for ERP (p
