  2. In the Beginning…. • CM Assessment (2004) recommended: • Identify and reduce backlogs • Integrate data sources • Document high level CM Plan (program) • Increase CM awareness • Develop CM Performance Indicators vs. CM Program • Monitor CM Health vs. CM Program

  3. Step One: What Is Our Backlog??? • First question: which backlogs? Why choose them? • Needed a comprehensive model on which to base our backlog assessment • We chose to use CM Conformance Restoration Diagram • The backlogs we measure were then systematically linked to the model

  4. CM Conformance Restoration Diagram

  16. Summary • Program is built on CM Conformance Restoration Diagram • Provides a picture of what CM is, how processes fit to satisfy CM requirements • Health reporting and metrics align with the model • Alignment and buy-in of senior management and regulator are promoted by a comprehensive, consistent approach
