BACKGROUND AND CONTEXT

• Traditionally, NASA Technical Standards Were
  Built Around Specific Programs and Organizations,
  e.g.,
• Apollo, Shuttle, Space Station, Explorers
• NASA Field Centers - MSFC, JSC,
• Liberal Use Was Made by NASA of MIL-STDS.
  Agencywide Technical Standards Were Generally
  Limited to Specific Areas
• Safety, Mission Assurance, Electronic Components
• Construction of Facilities
• Data Communications Standards
• Technical Standards Were Mainly Prescriptive and
  Essentially Good Forever

3
Program Objectives

• Establish and Maintain NASA Preferred Technical
  Standards As a Common Baseline for NASA Programs
• Develop Internal NASA Standards Where Available
  Standards Are Not Adequate
• Evaluate, Support, and Adopt National and
  International Standards Where They Meet NASAs
  Needs
• Support the Use of Technical Standards on NASA
  Programs in the Systems Requirement Process
• Provide Access for All nasa.gov Users to Full
  Text Standards From gt100 Sources at
  http//standards.nasa.gov
• Linking Standards to Lessons Learned for More
  Effective Use
• Automated Notice of Updates for Standards
  Registered by Users

NASA Technical Standards Definitions

• (1) Standards (STD) establish uniform
  engineering and technical requirements for
  processes, procedures, practices, and methods
  that have been endorsed as standard, including
  requirements for selection, application, and
  design criteria of an item.
• (2) Specifications (SPEC) are prepared
  specifically to support acquisition, which
  clearly and accurately describes essential
  technical requirements for purchased items.
  Procedures necessary to determine that the
  requirements covered by the specification have
  been met are also included.
• (3) Handbooks (HDBK) are guidance documents
  containing standard procedural, technical,
  engineering, or design information about
  material, processes, practices, and methods.

Standards Nomenclature

• Available Standards
• Anything Accessible Through Technical Standards
  Website
• Preferred Standards
• Recommended by Centers on Basis of Experience
• Centers Concur Acceptable for Appropriate Use
• No Major Issues Any Limitations Addressed in
  Applications Note
• Preferred Standards Are a Recommended Starting
  Point for Identifying Standards. Preferred ?
  Mandatory
• Can Come From Any Source
• Core Standards
• Finite List of Priority Standards Considered
  Critical for Controlling Risk, Addressing
  Recurring Problems, Providing Necessary Insight
  and Control Not Limited to Human Safety
• To Be Addressed by All Programs
• Implementation TBD

7
Standards vs. Requirements

• CAIB recommendation referred to both
  requirements and standards
• Standards are only part of Technical
  Requirements other types include
• Mission Design
• Program Manufacturing
• Performance (S/C) Test/Verification
• Performance (System) Operations

8
CAIB Recommendation

• 7.5.-1 Establish an Independent Technical
  Engineering Authority that is responsible for
  technical requirements and all waivers to them
  The Independent Technical Authority does the
  following as a minimum
• Develop and maintain technical standards for all
  Space Shuttle Program projects and elements
• Be the sole waiver-granting authority for all
  technical standards
• The Chief Engineer has been designated the NASA
  Technical Authority this authority is
  re-delegated to
• Discipline Technical Warrant Holders (responsible
  for requirements including standards)
• Systems Technical Warrant Holders ( providing the
  interface with programs

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 document status was not verifiable
• For all programs to date
• 7138 document update requests received
• 2362 document update notifications sent

22
Lessons Learned-Technical Standards Integration

• 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
• Over 600 out of 1700 Lessons Learned now
  hot-linked to 420 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 over 170 linked to date
• Use of Lessons Learned system climbing
