PROGRAM GOALS
NASA's Safety, Reliability, Maintainability, and Quality Assurance
(SRM&QA) program invests in the safety and success of all
NASA programs. The SRM&QA program develops insight into NASA's
programs and performs independent oversight that contributes to
program safety and success. The program develops and promulgates
necessary NASA-wide safety and risk management policies, standards,
and guidelines. Up-front quality management activities focus on
reducing costs, improving safety and reliability, including the
development and application of SRM&QA tools to support better,
faster, cheaper program development. Software assurance activities
include the implementation of NASA's software assurance improvement
program; development of tools and techniques; and oversight of
the performance of independent verification and validation (IV&V)
for critical flight, ground control, and robotics system software.
The SRM&QA program develops NASA-wide engineering policies,
standards, and guidelines; promotes the use of industry and international
standards for spaceflight systems; sponsors the development and
demonstration of methodologies for improved design, test, and
validation of systems and enhanced systems engineering capability;
supports independent review of proposed and on-going programs;
provides support to the NASA Program Management Council (PMC);
and, investigates advanced aerospace concepts.
STRATEGY FOR ACHIEVING GOALS
The SRM&QA program supports the activities of the Office of
Safety and Mission Assurance (OSMA) and the Office of the Chief
Engineer (OCE). The OSMA advises the Administrator and provides
leadership in promoting and ensuring the safety and quality of
all NASA programs through oversight of NASA programs and development
of Agency-wide Safety and Mission Assurance (S&MA) policies
and standards. OSMA efforts in the Policy, Oversight and Standards;
Quality Management; and Software Assurance programmatic areas
assist NASA's Strategic Enterprises in accomplishing their goals
in a safe and efficient manner. The OCE provides a focus for NASA's
engineering discipline, oversees application, and improves NASA's
practices and capabilities through targeted initiatives in the
Engineering programmatic area. The Advanced Concepts program for
conceptual study of new and unconventional aerospace ideas is
also part of the Engineering area beginning in FY 1998.
The Policy, Oversight, and Standards area addresses specific safety
and mission assurance needs in the new environment of better,
faster, cheaper missions and provides safety oversight and flight
readiness assessments for NASA programs. Documentation and analysis
of NASA experience in the SRM&QA disciplines, mishap investigations,
monitoring compliance with the Occupational Safety and Health
Act, and emergency preparedness planning improve safety and risk
management in NASA programs. NASA's implementation of the International
Organization for Standards' family of international quality standards
(ISO 9000), the NASA Engineering and Quality Audit, and the Advanced
Quality Practices program seek to improve the quality of NASA's
contracted work.
The Quality Management area supports the early introduction of
risk management and tailored safety, reliability and quality requirements
into aerospace systems design and manufacture. The expected results
are decreased lifecycle costs for NASA programs by reducing or
eliminating costly redesign late in development and test, and
increased probability of mission success. Specific efforts in
qualification test methods; non-destructive evaluation (NDE) technologies;
electrical, electronic, and electro-mechanical (EEE) parts and
packaging; and flight performance support these goals. The Quality
Management area also provides direct SRM&QA support to robotics,
aeronautics, and expendable launch vehicle programs.
The Software Assurance program supports the development of software
assurance standards, practices, and technology to evaluate flight
system, mission control, and science data system software. The
goal is assured, improved performance and reliability of the increasingly
complex and critical facility, ground system, and flight system
software used in NASA programs.
The Engineering area provides independent evaluation of engineering
technical and policy issues and coordination of engineering capability
development through NASA's Engineering Management Council. Development
of NASA engineering standards and policies and the use of appropriate
industry, national, and international standards will improve interoperability
and reduce the costs of aerospace systems; while improved practices
for systems engineering, structural analysis, and test methods
will increase the reliability and effectiveness of NASA programs.
The Langley Research Center (LaRC) will provide independent evaluation
of proposed and on-going programs in support of the NASA PMC review
process. The Advanced Concepts program provides an avenue for
introducing new ideas for advanced aerospace architectural and
systems concepts into NASA programs. The program's goal is to
stimulate and evaluate concepts from both internal and external
sources, and to ensure that ideas that show merit are considered
for support by NASA program offices.

ACCOMPLISHMENTS AND PLANS
In FY 1996, standards were completed for orbital debris (including
assessment software) and oxygen and hydrogen safety. A joint test
program with the Japanese Space Agency, NASDA, on liquid oxygen
and hydrogen explosion safety distances was completed. Assessments
and evaluations included Center S&MA self-assessments, several
hazardous facility assessments, the Mars Pathfinder Safety Evaluation
Report, and an independent assessment of initial program risk
management processes for the X-33. Probabilistic risk assessments
were performed for the Soyuz Crew Escape Vehicle and ISS. Shuttle
probability estimates were revised. The ISS IA developed an independent
critical risk assessment matrix and performed special technical
and programmatic assessments. Center implementation plans for
ISO 9000 were developed, kickoff orientation delivered, and compliance
gap analysis completed. Training courses were developed and piloted
for Certified Quality Engineer, Certified Reliability Engineer,
and Certified Quality Technician. Nineteen computer-based courses
were developed in S&MA disciplines including NDE, contractor
oversight, and performance-based contracting. A comprehensive
on-line S&MA training catalog was also developed. Calibration
standards for intrinsic voltage, and ultra-low and very high pressures
were developed. Also, a pooled process for calibrating equipment
at all Centers was instituted. A user-friendly lessons learned
database was placed on the World-Wide Web, and alternative approaches
to the current Failure Modes Effects Analysis/Critical Items List
risk assessment were developed. Eight Shuttle flights were supported,
and improved data collection techniques reduced S&MA costs
for ground processing.
Product and mission assurance requirements were specifically tailored
for Mars Pathfinder, Mars Rover, High Speed Research (HSR), and
Advanced Subsonic Technology (AST); and S&MA was involved
early in New Millennium program planning. NDE techniques for screening
advanced turbopump silicon nitride ball bearings (ultrasonic),
for composite pressure vessel certification and acceptance testing,
and for composite debond detection (laser shearography) were developed.
An automated orbiter window defect analyzer was developed and
certified for field use.
Operations and maintenance funding for the Fairmont, WV, IV&V
facility supported software assurance on Cassini, ISS, Shuttle,
and Earth Observing System Data Information System. A pilot formal
methods approach verified complete software assurance requirements
for Cassini. Additionally, a quantitative software methods and
measurements guidebook was baselined for Shuttle and the Space
Operations Management Office. Moreover, software domain reuse
principles were applied to wind tunnel control. Assurance techniques
continue to be developed for complex software systems, and a software
safety guidebook was produced.
In FY 1996, the OCE led the development of a qualification process
to enhance the reliability of commercial launch services acquired
by NASA and led the Pegasus XL Return to Flight Review Teamís
efforts to support program mission success. The OCE provided leadership
to develop the NASA Implementation Plan for the Federal Laboratory
Review; approved for NASA-wide application a series of structural
design and test standards; and established a Center-led program
to implement additional consolidation and upgrades of current
engineering practices. The Design, Test, and Verification program
extended the NASA fracture analysis methodology to aging aircraft
problems through cooperative agreements with the FAA. This program
also supported verification tests of the damage-reducing, force
limited vibration technique to additional payloads and began planning
for a Shuttle flight verification of the technique. The OCE Battery
program conducted life tests and operational simulations of NiCd
and NiH2 battery cells in support of spacecraft and Space Station
qualification programs. JPL used the Battery Test Bed to develop
and verify power management and optimization techniques for on-orbit
spacecraft. Eight competitively selected projects were initiated
with Advanced Concepts Research Fellows at universities and private
institutes. Topics included propulsion, inflatable structures,
spacecraft architectures, electronic components, and robotics.
Contracted studies to examine advanced concepts for highly reusable
space transportation systems were initiated, and a "virtual
research center" system was deployed.
In FY 1997, OSMA will conduct oversight for NASA's seven planned
Space Shuttle flights. Transition to the Shuttle Flight Operations
Contract (SFOC) will be supported, and an improved, low-cost,
easy-to-use Problem Reporting and Corrective Action system will
be completed. The ISS IA will continue to evaluate the program's
technical health and capability to safely achieve its program
objectives, including software IV&V, with co-funding from
the Office of Space Flight. Significant lessons learned and reliability
and test best practices will be collected and distributed throughout
NASA. Risk management and assessment techniques will be developed,
refined, and applied. Reliability-centered maintenance techniques
and processes, an orbital debris hazard and risk mitigation process,
and hydrogen fire detection and smoke movement modeling for high
bays will be established. NASA, government, and private sector
education and training courses will be identified and integrated
into NASA's SRM&QA training and professional development curriculum.
New courses will be initiated to cover gaps or advancing technology.
Advanced quality concepts will allow routine use of private sector
best practices, principles, and metrics to achieve comparable
or improved safety, reliability, and quality at less cost. ISO
9000 will be fully integrated as NASA's baseline standard for
quality management systems, and NASA Engineering and Quality Audits
will be regularly employed.
Mission assurance support for New Millennium and other spacecraft
and aeronautics programs such as High Speed Civil Transport and
Advanced Subsonics will continue. Processes will be in place to
develop appropriate S&MA requirements tailored to cost, schedule,
and risk. Emphasis will be placed on test effectiveness and on
correlating S&MA requirements with flight performance to provide
real-time evaluation and feedback to the specific programs. Effective
test programs incorporating test histories, flight performance,
and flight results will be conducted. Advanced EEE parts and packaging
techniques will be employed to develop qualification and test
methods for fiber optics, micro-electro-mechanical systems, micro
actuators, and sensors that determine quality and reliability
issues. The space radiation effects program will determine microelectronic
parts radiation tolerance.
Software assurance will continue to assure flight, ground control
and robotics system software. Research initiatives in verification
and validation techniques, tools, and training course development
will be conducted. Verification and validation best practices
will be identified and applied to mission critical software projects.
In FY 1997, in response to the decision to assign LaRC the responsibility
for program analysis and evaluation, the OCE will expand the Langley
Research Center (LaRC) mission concept and analysis capability.
The LaRC, using it's broad systems analysis capabilities, will
provide independent assessment of conceptual designs relative
to design integrity, system/subsystem trades, life-cycle costs,
schedule estimates, risk and risk mitigation approaches, and technology
issues. The LaRC will lead the Agency's program evaluation (PMC
reviews) by organizing and participating in inter-center Non-Advocate
Review (NAR), Independent Annual Review (IAR), and Independent
Readiness Review (IRR) teams. In addition, it will provide specialized
technical analysis to support review areas of particular concern.
The OCE Standards program will continue consolidation of internal
standards and will expand cooperative projects with non-Government
standards, developing organizations to increase NASA use and support
of national and international consensus standards. The Design,
Test and Verification program will initiate projects applying
probabilistic analysis techniques to structural design to improve
design margin management and increase system assurance. The program
will also complete assessment of the impact of chloro-flourocarbon
replacement cleaners on lifetimes of precision mechanical systems
such as scanners and gyroscopes. The OCE Applied Technology program
will complete testing to evaluate solutions to failure modes of
pyrotechnic operated valves. The Aerospace Battery program will
complete technology evaluation and initiate cell tests for Li-ion
battery systems; conduct performance testing and physical analysis
for advanced NiCd, NiH2, and AgZn battery cells; and develop a
stress test for NiH2 cell qualification procedure. The Advanced
Concepts Program will be restructured to place more emphasis on
soliciting external ideas and concepts. An External Advanced Concepts
Institute will be established to provide a forum to stimulate
and analyze external concepts for new systems approaches to NASA
missions. Each Enterprise will establish a process for soliciting
and evaluating relevant concepts from any source, and the "virtual
laboratory" concept will be established at several Centers
for faster, more effective concept evaluation.
The FY 1998 budget supports critical agency infrastructure to
maintain safety and mission success with decreasing agency resources
and dramatic changes in business practices. Specific safety and
mission assurance needs in the new environment of better, faster,
cheaper missions are addressed. Independent assessment of the
Space Shuttle and ISS programs is maintained. OSMA will fully
fund the ISS IA effort (including software), a change from prior
years. Tools, techniques, and procedures are developed to replace
audit-based oversight with insight. Process verification techniques
and data will ensure process stability and capability. Assurance
for better, faster, cheaper missions moves from rule-based to
knowledge-based approaches. Acquisition reform goals of efficiency
and effectiveness through the Single Process Initiative, ISO 9000,
and Performance-Based Contracting (PBC) are supported. The Professional
Development Initiative and related training course development
responds to projected S&MA skill mix problems. The results
of implementing ISO 9000, PBC, and other contracting initiatives
will be evaluated. Seven Shuttle flights will be supported and
the performance of the SFOC evaluated.
The test effectiveness program and techniques for trading risk
will enable informed test planning for better, faster, cheaper
missions and improved risk management. Development of advanced,
unique NDE techniques and studies on probability of detection
will support longer life aerospace components. Product assurance
support for "Instruments on Chips" will help lead to
dramatically lighter and lower power electronics. The EEE parts
and packaging effort maintains the mission reliability of rapidly
evolving semiconductor technologies by performing radiation screening
for advanced new parts; establishing technology readiness for
insertion of emerging technology into microspacecraft; enabling
the selection of commercial-off-the-shelf devices for better,
faster, cheaper spacecraft and instruments; and, providing assurance
for micro-electro-mechanical systems devices.
The Software Assurance program will continue to research, develop,
pilot, and evaluate standards, tools, techniques, and processes
to ensure the safe and reliable performance of increasingly complex
critical mission software.
In FY 1998, the OCE's Standards program will establish a "Preferred Standards" system for NASA that completes consolidation of design practices and integrates the use of national and international consensus standards in space system development, test and implementation. Continued development of international standards for space systems through ISO will assist international cooperation and enhance U.S. competitiveness. International Product Data Standards will be used in system design and analysis for structures, thermal systems, and optical systems. Improvements to design, test, and validation capabilities will focus on improving analytic methods and tools for evaluation of structural design. The Aerospace Battery Technology program will be transferred to the Space Science Enterprise in FY 1998 to continue qualification of advanced chemistries and operational support and evaluation of flight battery systems. The LaRC will continue to independently assess advanced mission concepts and will assume full responsibility for supporting NASA Program Management Council reviews of proposed and ongoing programs. New and enhanced analytical methods and tools for Advanced Concepts will be incorporated at NASA Centers to enable simulation-based design, collaborative computing, and interactive design team studies. The External Advanced Concepts Institute will sponsor workshops and conferences to focus attention on promising new high-potential technology areas for future NASA missions.
