Program Goals And Authority

• Goals
• Support NASAs engineering function through
• Providing the technical standards needed for NASA
  programs
• Improving the practice of engineering by
  integrating experience into the engineering
  process
• Authority
• NPD 8070.6B, Technical Standards, May 7, 2003
• NASA Preferred Technical Standards Program Plan,
  April 15, 1999
• NPG 7120.5B, NASA Program and Project Management
  Processes and
• Requirements, November 21, 2002

  and Advancement Act of 1995
• OMB Circular A-119, Federal Participation in the
  Development and Use of Voluntary Consensus
  Standards and Conformity Assessment Activities
  (1998)
• NPG 8070.x , Technical Standards Processes (In
  Development)

Background And Context

• Traditionally, NASA standards were built around
  specific programs and organizations
• Shuttle, Space Station, Explorers
• NASA field centers - MSFC, JSC,
• Standards frequently included technical and
  programmatic requirements
• Substantial use was made of Mil-Stds.
• NASA-wide technical standards were generally
  limited to specific areas
• Safety, Mission Assurance, electronic components
• Construction of Facilities
• Data Communications Standards
• Technical standards were generally presumed good
  forever until the next program decided to
  change them or specific problems were found

4
Current Approach

• Today
• Create and maintain common, multi-program NASA
  Technical Standards for NASA unique needs
• Make maximum use of applicable national and
  international standards through adoption as
  NASA Preferred Technical Standards (PL 100-113)
• Reference existing standards as is with
  program/ project tailoring (not re-write) to
  maintain traceability
• Use of Preferred Standards is voluntary
• Future?
• Mandatory technical standards with waiver through
  Independent Engineering Technical Authority
  (Columbia Accident Investigation Board
  Recommendations)
• NASA Core Standards?
• Program Lists?

Program Elements

• Development of NASA Technical Standards
• Support and Adoption of Voluntary Consensus/
  Non-Government Standards (PL100-113)
• Transition of Center-Developed Standards with
  multi-program application to NASA Preferred
  Technical Standards (NASA or Non-Government)
• NASA Integrated Technical Standards System
• Agencywide Full-text Technical Standards System
• Standards Update Notification System (SUNS)
• Hot link integration of Lessons Learned/Best
  Practices/Application Notes with NASA Technical
  Standards
• Standards Awareness

9
Standards Program Processes

• Engineering standards needs are identified
  through Centers and/or Discipline Working Groups
• Formal process (separate from Directives
  Management System) controls proposals submittal,
  screening, development, Center review, and
  approval
• Center Engineering Management Board member
  provides Center approval
• Chief Engineer approves for NASA
• Standards from other functional areas (Codes Q,
  AO, M) approved by HQ Associate Administrator
• Future
• Common management process for all NASA Standards
• Enterprise concurrence for policy, overall impact

10
NASA Preferred Technical Standards Taxonomy
11
NASA Preferred Technical Standards

• 59 NASA-Developed Technical Standards
• 20 Engineering Standards
• 20 Information Technology Standards
• 19 Safety and Mission Assurance Standards
• 2241 Adopted Standards
• 1550 Non-Government Voluntary Consensus Standards
• 663 DOD/MIL-STDs
• 28 Federal CID Standards
• In Development or Pending Adoption
• 33 NASA Technical Standards in Development
• 17 NonNASA Technical Standards In Development
• 719 Additional Standards Are Identified as
  Potential for Adoption
• NASA Participation in the Standards Development
  Organizations in FY04
• 144 employees participating in 33 different
  Standards Developing Organizations
• Leading or participating in the development of
  197 Non-govt standards

12
Agencywide Full-text Technical Standards System

• Initiated in FY2000 competitive, 5 year, fixed
  price contract
• Non-Govt Standards Listings available to public
  full text documents to nasa.gov only
• Provides one stop, transparent access to
  standards from more than 111 Standards Developing
  Organizations (SDOs)
• NASA preferred technical standards
• Technical standards developed by NASA
• Adopted standards from other sources
• Center developed standards (JSC, KSC, MSFC, etc.)
• Program documents Shuttle, Space Station,
  Payloads
• Other government standards (FAA, Navy, DoD, DoE,
  etc)
• Links to related technical information (I.e.
  Material and Metal Database, SPECSINTACT,
  Logistic Parts Database, etc.)
• Sophisticated, but user friendly search
  capability
• Extensive metrics accesses, downloads,
  documents, requestors...

Standards Update Notification System (SUNS)

• SUNS allows users to register standards they use,
  and receive automatic notification when standards
  are revised, re-issued
• Changes to technical standards can have major
  impacts on the safety, performance, reliability,
  and cost of programs/projects
• Using out-of-date standardsunless required to
  meet specific need
• Ignores improvements and misses the benefits of
  experience
• Exposes programs/projects to the risk of
  repeating those failures that led to update of
  the standard
• Pilot Test on Space Shuttle Solid Rocket
  Booster/TVC System
• 552 standards cited all but 124 cancelled,
  replaced, or uncontrolled
• For all programs to date
• Over 6000 document update requests received
• Over 1600 document update notifications sent

Integration Of Lessons Learned/ Application
Notes With Standards

• NASA Lessons Learned System documents problems
  and improved guidance from program and project
  experience
• Linking Lessons Learned with standards provides
  basis for interpretation/use and update of
  standards
• Users alerted to Lessons Learned at the time they
  come looking for the standards
• Current status
• 543 out of 1700 Lessons Learned now hot-linked to
  355 NASA preferred and non-government technical
  standards
• Reverse search capability permits users to view
  specific lessons learned by technical discipline
  and view the standards linked to them
• Now adding Application notes from standards
  users that clarify or limit the scope, use, or
  context of standards 168 linked to date
• Use of Lessons Learned system climbing
