2 PR70007 – MarkeTrak Ph2 ERCOT Project Strategy Objective: ERCOT Project Lifecycle Overview Discuss the Planning timeline Discuss the approach of the Workstreams at ERCOT Goal: Move from Initiation to Planning

3 ERCOT Project Lifecycle

4 Divisional Projects Organization Overall Management of:  Portfolio of Projects  Program Area Structure  Project, Priorities & Reporting and Monitoring Project Management Process Management of:  Budgets and Approvals  Project Delivery  Resources, Costs, Timelines Initiation of Project Requests:  PUCT Rulings  System Change Requests (SCRs)  Protocol Revision Requests (PRRs)  Nodal PRRs (NPRRs)  ERCOT Project Requests (PRs) ERCOT DPO / Executive Committee ERCOT DPO / Executive Committee ERCOT PM Process ERCOT PM Process PUCT Market Participants ERCOT Projects Pipeline Origin of Projects

5 Project Phases and Deliverables **Note: All Consistent with PMI Standards

10 ERCOT Recommendation for Option 2 Benefits Begin Execution in Q108 Approved funding for 2008 Higher Potential to begin/complete implementation in 2008 Dependencies May require more brainstorming session Market SME Participation during requirements critical

11 Approach to Workstreams

12 Workstreams ERCOT recommends categorizing Requirements into workstreams Allows ease of prioritization Allows ease of packaging like system impacts Allows ease of release planning during Execution Allows further definition of each requirement into a deliverable DEV shops perform Impact Assessment of Use Case Questions addressed, Workstream Assigned Use Case Defined at Task Force
