Mission Success Starts With Safety • Safety Starts With Engineering Excellence
NASA Engineering and Safety Center
• On July 15, 2003, Administrator O’Keefe announced plans to create the NASA Engineering and Safety Center at Langley Research Center.
The Center will provide a central location to coordinate and conduct robust, independent engineering and safety assessments across the Agency.

Mission Success Starts With Safety • Safety Starts With Engineering Excellence
NASA Engineering and Safety Center
• NESC philosophy and culture
– Safety through Engineering Excellence
– Mission Success Starts with Safety
– Safety Starts with Engineering Excellence
NESC will cultivate a Safety culture by providing knowledgeable technical leadership
to perform independent in-depth technical assessments in an open environment
with unequalled tenacity.

Mission Success Starts With Safety • Safety Starts With Engineering Excellence
NASA Engineering and Safety Center
• NASA lacks “value added” independent assessment of technical issues within its programs and institutions.
• NESC created to provide independent assessment of technical issues– Scope
• Independent in-depth technical assessments• Independent trend analysis• Independent systems engineering analysis• Mishap Investigations• Support Programs• Focus on High Risk Programs
• NESC independent assessment uses discipline experts from across NASA and Nation in Super Problem Resolution Teams
5
Mission Success Starts With Safety • Safety Starts With Engineering Excellence
NESC Principles of Operation
• Proactive – Test and analysis of issues or trends not currently
being addressed by the program
• Active – Independent review of known risk areas
• Reactive – Independent investigation of mishaps and close calls
• Set example for safety culture through engineering excellence
• Encourage/document /disposition dissenting opinions
• Measure performance with metrics
6
Mission Success Starts With Safety • Safety Starts With Engineering Excellence
NESC Personnel / Staffing
• NESC permanent staffing includes: – Principal Engineers located at NASA Langley – NESC Chief Engineers (NCE) located at each NASA Field
Center– Systems Engineers located across the Agency– NESC Discipline Experts (NDE) for specific disciplines located
across the Agency• Fluids/Life Support/Thermal, Flight Sciences, Guidance Navigation &
Control, Human Factors, Materials, Mechanical Analysis, Mechanical Systems, Non-Destructive Evaluation, Power & Avionics, Propulsion, Software, Structures
– Chief Scientist & Chief Astronaut• NDE’s, Chief Scientist & Chief Astronaut are the leaders of National
expert teams…called Super Problem Resolution Teams (SPRT)
7
Mission Success Starts With Safety • Safety Starts With Engineering Excellence
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
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

Mission Success Starts With Safety • Safety Starts With Engineering Excellence
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
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

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
