This document discusses the importance of modeling and metadata management for businesses. It notes that 60% of IT projects fail or only partially succeed due to poor alignment between business and IT. Effective modeling helps ensure business goals, rules and requirements are met and that changes can be implemented with minimal risk, time and cost. Metadata management provides business agility, aids regulatory compliance, and forms the foundation for service-oriented architectures. The document promotes PowerDesigner as the leading tool for conceptual, logical and physical data modeling as well as enterprise architecture and metadata management.
