5. 5 Why Cleanup >10+ years of development in a single data model by many people >Data models contain large numbers of redundant, retired and superceded objects >Longer timeframes and higher costs to maintain objects no longer required and used >Size of data models impacts performance of developers and increases generation times

6. 620 September 2007 6B - Picture This! Using 2E with Graphical Tools Copyright © 2007 CA Benefits for a Cleanup >Data model size will be greatly reduced >Lower ongoing project costs and timeframes >Better quality documentation and understanding of development environment >More accurate impact assessments and development estimates
