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.

3



• 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.

4



• 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


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


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


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

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


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
