  1. Integrated Schedule Review Nodal PMO TPTF

  2. Agenda • Program Changes (Janet Ply) • Preliminary Nodal Integrated Master Schedule (Janet Ply) • Scope (Janet Ply) • Schedule Assumptions (Janet Ply) • Work Remaining by Project (Core PMs) • Integration Activities (Mike Bianco) • EDS Activities (Matt Mereness) • Key Program Milestones (Janet Ply) • Critical Path (Janet Ply) • Next Steps (Janet Ply) Integrated Schedule Review

  3. Program Changes • Reorganized the entire program to eliminate project silos; instill accountability; put the right people in the right roles; streamlined delivery • Changed leadership: Ron Hinsley is the Executive Sponsor and the Executive Director; Janet Ply now leads the nodal Program Management Office (PMO) • Projects were reorganized into core and supporting projects; core projects own end-to-end delivery • Developed a Nodal Master Integrated Schedule; identified hundreds of project inter-dependencies that were previously unknown • Developed comprehensive program controls that are used rigorously to manage work • Increased executive involvement in anything that affects program scope • Increased vendor oversight and vendor accountability; have put ERCOT staff onsite and have vendor staff onsite at ERCOT during critical times • Staffing has been reviewed; 108 contractors have left the nodal program since June; 18 contractors have been converted to ERCOT employees • Increased ERCOT home team involvement in several key areas Integrated Schedule Review

  4. Restructured Projects • Network Model Management System • Linda Clarke leads this effort • Established data quality teams for the RARF data collection from Market Participants and for “nodalizing” the zonal seed for the network model (Common Information Model (CIM)) • ERCOT Readiness and Transition • Murray Nixon leads ERCOT readiness and transition (i.e. business process development) • EDS • Matt Mereness leads EDS and MP readiness metrics • Enterprise Integration Services, Integration Testing • Combined these projects, renamed to Systems Integration and moved under the PMO • Mike Bianco leads this effort and comes from CAISO • Consolidated the zonal and nodal integration testing teams into one, added structure • COMS team • Hope Parrish, ERCOT Manager, leads this team • Justin Rasberry brought in to oversee Settlements and Billing and Commercial Systems Interfaces (CSI) • Reorganized the Credit Management and Monitoring (CMM) team to accelerate progress Integrated Schedule Review

  5. Results of Changes • A high level of executive oversight and involvement • The right people in nodal leadership positions • Strong program controls and processes • Vendor focus • Team member accountability • Sense of urgency to deliver the Nodal program on schedule ERCOT now has Integrated Schedule Review

  6. Preliminary Nodal Integrated Master Schedule • In June, PMs replanned the nodal program across all project teams resulting in • An improved understanding of the scope of the work required through go-live, now scheduled for Dec.1, 2010 • A comprehensive understanding of cross project dependencies for the nodal program • A detailed integrated master schedule for the nodal program that is the single source of record for all nodal work to be performed (~5400 activities) • Most importantly, a realistic schedule with a high degree of confidence that the nodal program can be delivered on schedule • Integrated master schedule has undergone numerous reviews and audits • ERCOT has been using this integrated schedule and supporting reports successfully to manage the program and project critical paths • ERCOT needs to incorporate MP activities and feedback, scheduled for TPTF meeting on Tuesday, Dec. 16, before the schedule can be finalized Integrated Schedule Review

  7. Scope Nodal program scope included in the integrated schedule Approved requirements and conceptual system design documents All NPRRs approved through Nov.17, 2008 Additional scope to process to be included Remaining business process work Remaining requirements traceability work No impact to the program critical path for this work Note 1: No schedule contingency has been included in the integrated master schedule; any additional scope/effort that is required will go through the nodal change control process and impacts to the schedule and budget will be captured Note 2: Removing and/or clarifying scope that affects any of the nodal systems at this point does not necessarily decrease effort Integrated Schedule Review

  8. Schedule Information Integrated Schedule Review

  9. Schedule Assumptions No new software vendor releases will be required past what is already planned (remaining scheduled releases will be covered in each individual project) Preserved the EDS durations as defined in the handbooks Market participant activities that were placed on hold are not restarted until the NMMS/EMS/MMS5 systems are on a synchronized model (schema and data set) Market participants will continue to participate in ongoing nodal EDS activities Integrated Schedule Review
