6. New Scope Phase and Scope Deliverables • The Scope Phase Provides the Following: • Defines Solution Purpose and Functionality • Provides Foundation for Release Management and Change Control • Provides Direction and Priorities for the Business Analysis phase and all Subsequent Phases • Facilitates Consensus and Common Understanding Among Participants • Defines Release Critical Success Factors COMMUNICATIONS Scope Business Analysis Functional Design User Interface Design p Technical Design Physical Design / Build / Test UAT Test COMMUNICATIONS

7. New Scope Phase and Scope Deliverables • Functionality Matrix Example Deliverable: R1 • limited to 1 Admin • unavailable

8. New Scope Phase and Scope Deliverables • Business Functional Flow Example Deliverable:

9. 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

10. Technical Design Phase New Deliverable • Technical Requirements Definition and Flow: Typical Examples • SMT Business Validation • Portal access, Web service, FTP • Push to REP, Pull from SMT • Non-functional requirements

11. SMART METERTEXAS Proposed Change Control Process

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