NASA Technical Standards Program Overview Joint Technical Architecture for Robotic Systems (JTARS) Working Group Meeting Houston, Texas May 11-12, 2005 • Paul S. Gill • Manager, NASA Technical Standards Program Office • http://standards.nasa.gov Danny Garcia/NASA Technical Program Office
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-STD’S. 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” BACKGROUND AND CONTEXT
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 NASA’s 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 >100 Sources at http://standards.nasa.gov Linking Standards to Lessons Learned for More Effective Use Automated Notice of Updates for Standards Registered by Users Program Objectives

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.
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 Standards Nomenclature
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 Standards vs. Requirements
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 CAIB Recommendation

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 standards—unless 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
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
