New Scope Phase and Scope Deliverables Business Functional Flow Example Deliverable:

New Scope Phase and Scope Deliverables Release Critical Success Factors Example Deliverable: Release Critical Success Factors for Smart Meter Texas Release 1 The solution must provide a common web portal The user online interface must be intuitive and easy to use by consumers The solution must provide a secure environment for confidentiality, user access and data transfer The solution must provide the information necessary in which the customer can make an informed decision regarding consumption The solution must be provide a common format to manage meter and In- Home Device functions The solution must be based on existing open industry standards The solution must be based on a common interoperable platform

Technical Design Phase New Deliverable Technical Requirements Definition and Flow: Typical information Portal access, Web service, FTP Push to REP, Pull from SMT Non-functional requirements

SMART METER TEXAS Proposed Change Control Process

Change Control Process AMIT or Market Participant Fills Out and Submits Change Control Detail Request to PUCT PUCT Assigns Change Control Number and Enters in Change Control Log AMIT Reviews Change Control Detail Requests at 1 st Monthly AMIT Market Change Control Meeting Archive Change Control Detail Request and Mark Change Control Log as Rejected AMIT Approve / Reject Approve Reject SMT Team Conducts Impact Analysis Including: Functions Impact, Time Estimate, and Cost Estimate AMIT Defines Priority and Potential Release for Change at 1st Monthly AMIT Market Change Control Meeting SMT Team Submits Impact Analysis Including the Time Estimate, and Cost Estimate to PUCT Review Change Control Detail Requests & Impact Analysis at the 2 nd Monthly AMIT Market Change Control Meeting Archive Change Control Detail Request and Mark Change Control Log as Rejected PUCT Approve / Reject Approve Reject Refine Priority and Define Release for Change During the 2 nd Monthly AMIT Market Change Control Meeting Acquire Signatures on Approved Change Control Form and Submit to SMT Team for Project Planning Poll Market to Identify if a Market Participant Wishes to Fund the Change Market Approve / Reject Reject Approve

Change Control Form – Detail Request from Market

Change Control Form – Impact Analysis

Change Control Form – Time and Cost Estimates

Change Control Form – Approve or Reject Sign Off

SMART METER TEXAS Proposed Issue Escalation Process

Proposed Issue / Requirements Clarification Escalation Process for Application Development SMT Team or AMIT Fills Out and Submits Issue or Clarification Description Form to PUCT Jenina Manages Issue or Clarification Documentation for Review at Next AMIT Meeting AMIT Reviews Issue and Selects / Refines Resolution Option SMT Team Develops Proposed Resolution Options with Impacts to Timeline and Cost AMIT Submits Resolution to SMT Team COMMUNICATIONS 1.Market Notices 2.SMT Status meetings 3.AMIT meetings 1.Market Notices 2.SMT Status meetings 3.AMIT meetings

SMART METER TEXAS Next Steps

Release 1 Functionality Matrix Release 1 Business Process Flows Release 1 Business Technical Flows Release 2 Critical Success Factors Future Business Requirements Review Proposed AMIT Methodology and Next Steps
