1. 1 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

2. 2  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

3. 3 Program Objectives Establish and Maintain ”NASA Preferred Technical Standards” As a Common Baseline for NASA ProgramsEstablish 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 ProcessSupport 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

5. 5 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. (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. (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.
