1. Maintaining Configuration Control with the Engineer of Choice Saturday, April 25, 2015

2. PAGE 2 PRESENTATION TITLE Definitions 1.Configuration Management (CF1) An integrated process that identifies existing plant design and licensing requirements and controls changes to ensure that the plant is configured, maintained, operated and managed that is consistent with the design bases and licensing commitments 2.Engineer of Choice (EOC) Contracted engineering firm brought in to support design modifications for the medium to large size projects

3. PAGE 3 PRESENTATION TITLE Definitions 3.Technical Coordinators (TC) Senior level design engineers working with the EOC to ensure that existing design and licensing requirements are met for all design modification produced by the EOC TCs are part of the Engineering Outsource (EOUT) group. This group also has the PG&E bargaining unit design engineers. 4.Owner’s Review Group (ORG) Senior level management group providing in process design review of the EOC’s product

4. PAGE 4 PRESENTATION TITLE Keys to Success 1.Develop the right model 2.Select the right partner 3.Create the right process 4.Monitor, Trend and Train on the process

5. PAGE 5 PRESENTATION TITLE Develop the Right Model 1.Management must decide on the “Right EOC Model” Single or Multiple Engineer of Choice firms Competitive bidding for design projects or awarding based on strengths of the particular EOC 2.Management must be committed Provide budget (projects) to sustain EOC Provide in house support for the EOC Support the “Right Model”

6. PAGE 6 PRESENTATION TITLE Select the Right Partner 1.Select an EOC partner that wants to be a “Partner” in the success of the EOC model Long term commitment Willing to share expenses and profits Provides their best people 2.Select an EOC that has knowledge of your design and licensing bases DCPP fortunate to have EOC staffed with ex-PG&E design engineers DCPP “salted” the initial onsite EOC with 12 long term experienced design engineers

7. PAGE 7 PRESENTATION TITLE Create the Right Process 1.Develop the process to support the EOC Create a special group with the charter to make the EOC successful (EOUT) Provide key senior level design engineers to provide direction and oversight to the EOC Provide written standards for the EOC to follow Provide procedures that have enough information (i.e checklists, meeting formats) Provide formal feedback and lessons learned Provide senior level management oversight (ORG)

8. PAGE 8 PRESENTATION TITLE Monitor, Trend and Train 1.Monitoring the design change process Technical coordinators from the EOUT group provide oversight of the EOC during the design phase of the project Design change procedure (CF3.ID9) processes (Scoping and Rev A meetings) Owner review group (ORG) provide oversight at least two points during the design phase of the project TC in depth review of the EOC’s independent technical review of the design change Post Rev 0 issuance meeting to provide immediate feedback to the EOC Post implementation meeting (Rev Z) to provide feedback to the EOC QV audits and engineering assessments

9. PAGE 9 PRESENTATION TITLE Monitor, Trend and Train 2.Trending the design change process The CAP is used during all phases of the project (Design, Planning, Implementation and Testing) Post Rev 0 meeting results are used to trend lower level issues as well as feeding into the CAP Post implementation (Rev Z) meeting results are used to trend lower level issues as well as feeding into the CAP 3.Training the EOC in the design change process Initial training by use of the mentoring process (12 experienced design engineer and the TCs) as well as procedure training Ongoing training driven by procedure revisions is conducted in formal classroom setting Ongoing training driven by the CAP is a combination of tailboards during staff meetings and formal classroom (dependent on the severity of incident) Lessons learned generated by the Post Rev 0 and Rev Z meetings are provided during staff meetings

10. PAGE 10 PRESENTATION TITLE Summary The program objectives for design change aspects of Configuration Management are being met. Since the creation of the EOC at DCPP (2006) the following statistics have been compiled: Design changes created that have been scored77 Percent of “Green” or “White” designs (Rev Z)90% Percent of “Green” or “White” designs (Post Rev 0)85% Note: Green or White indicate the designs were of acceptable design quality, resolved the problem to the key stakeholders satisfaction and did not create any new problems The high percentage acceptable design changes is an indication that the creation of the EOC and the EOC process is working at DCPP. The difference in the percentages of Rev Z and the Post Rev 0 is an indication that the use of knowledgeable senior level Technical Coordinators and having knowledgeable management oversight (ORGs) are factors in maintaining configuration control.
