    10. ©USC-CSE 10 Example Experience Factory Approach: Goal-Model-Question-Metric and Shared Vision 1. Proposed Goal: Reduce Software defect rates, delivered defect density 2.

    11. ©USC-CSE 11 Example Experience Factory Approach: Goal-Model-Question-Metric and Shared Vision 2. Relate to system goal shortfalls: ask why initiative is needed Too much downtime on operations critical path Too many defects in operational plans Too many new-release operational problems 3. Formulate system-level goal: Decrease software-defect-related losses in operational effectiveness With high-leverage problem areas above as specific subgoals 4.

    12. ©USC-CSE 12 EF Approach: GMQM and Shared Vision 4. Perform system problem-area root cause analysis: ask why problems are happening via models Example: Downtime on critical path

    13. ©USC-CSE 13 EF Approach: GMQM and Shared Vision 4. Perform system problem-area root cause analysis 5. Identify candidate improvement initiatives Use Opportunity Trees to sort out options 6. Develop Results Chains for improvement initiatives Identify Success-critical stakeholders 7. Develop stakeholder win-win Shared Vision package Top- level goals, models, questions, metrics 8. Develop, execute, monitor, control Initiative Plans
