This study analyzes twenty-three successful data warehouse implementations along Porter’s (1985) value chain model. It identifies the commonalities among the implementations in terms of project justification by applying the competitive advantage concept. A conceptual model, “Justification Grid of Data Warehousing,” provides a framework for organizations considering data warehousing that allows them to assess and evaluate data warehousing projects strategically. The framework is a complementary approach to cost-benefit analysis (CBA) in a comprehensive, organization-wide project justification.
