7. Mission Success Starts With Safety Safety Starts With Engineering Excellence 7 Super Problem Resolution Teams (SPRT’s) SPRT’s are the backbone of the NESC SPRT’s shall have membership from multiple sources –NASA, industry, academia, other Government Agencies and possibly international experts SPRT’s will provide technical support of NESC assessments –Independent expertise/reviews and leadership –Independent test, analysis and evaluation – not just technical opinions Changes/additions to SPRT’s will be negotiated with the team members and their respective NASA Centers/organizations, as required

8. NESC SPRTs – Form & Function Guidelines SPRT Tech Experts – Roster of focused discipline experts with skills / capabilities in a particular field of the discipline Conduct Test, Analysis, Evaluations in their field of expertise in support of NESC ITA/Is Readily Accessible Considered the Best of the Best Matrix support to NESC as Requested On Call to Support an IAT/I Time / resources covered by NESC PWC SPRT Core – 10 to 30 experts with broad based experience and knowledge across the range of the discipline plus several crosscutting engineering specialists as appropriate Regular SPRT Telecons (bi-weekly) Peer Review of IAT/I Products Think Tank for Discipline Annual Working Group Meetings Low Level Continuous Support to NESC Time Covered via NESC PWC On Call to Support an IAT/I Sub-team leads as appropriate to support discipline SPRT expert(s) assigned to ITA/Is NESC Director / Review Board (NRB) NESC Chief Engineers (NCE) NESC Discipline Experts (NDE) NESC Principal Engineers (NPE) Independent Technical Assessment / Inspection (ITA/I) Team Super Problem Resolution Team (SPRT) Core SPRT Tech Experts (NASA) SPRT Tech Experts (Other Govt. Agency) SPRT Tech Experts (Industry) SPRT Tech Experts (Academia) ITA/I Team – NESC led team of independent experts conducts independent test, analysis and inspection on selected requests Primarily Led by NPE Could be NDE or NCE Comprised of Discipline SPRT experts

9. Mission Success Starts With Safety Safety Starts With Engineering Excellence 9 Benefits to being an SPRT Member Provides an opportunity to interact with the best of the best in NASA, Industry, Academia and other Government Agencies Challenging assignments & interaction with discipline experts –Invaluable Experience gained helping resolve NASA’s critical issues –High Impact / High Feedback / High Visibility / Job Satisfaction Growth through addressing broad spectrum of technical issues and gaining experiences within chosen discipline –Problem Resolution Team is a challenging experience –Recognition and Interaction within technical discipline

10. Mission Success Starts With Safety Safety Starts With Engineering Excellence 10 Benefits to being an SPRT Member (cont.) Exposure to other NASA programs, projects, cultures, methods, business practices across the agency Potential career development experiences and opportunities –NESC is pursuing human resource initiatives and benefits to supporting NESC Provides a review team for Programs and Projects members to identify their own project concerns and issues for the SPRT to review and decided if further study/review is required

11. Mission Success Starts With Safety Safety Starts With Engineering Excellence 11 Organization Benefits of Supporting NESC Provides employees opportunity to interact with the best of the best in NASA, Industry, Academia & other Government Agencies Comprehensive expertise obtained through NESC agency level experience broadens employees technical experience –Across full spectrum of discipline –Provides a better employee through this experience –Teaches method for problem resolution and how to obtain corrective actions Lead & Participation in a “OneNASA” initiative Exposure to other NASA programs, projects, cultures, methods, business practices across the agency –Broadens employee horizons via wide network of interaction –Gains experience outside employee’s own work area Potential for NESC funding Recognition of Discipline Expertise within your center/organization
