4. STANDARDS DEVELOPMENT • SAE Stress Relieving Standards (SAE AMS 2759/11) • Good News For This Standard. SAE AMS 2759/11 For The Stress Relieving Of Ferrous Alloys Has Been Approved by AMEC And Was Balloted AT Committee E (Carbon and Alloy Steel).  Just Attended Committee E Meeting In San Diego From 9/28-9/30/2004. The Standard Is Approved. There Will Not Be Any More Balloting. The Only Thing We Need To Do Is To Work With SAE On Proper Format. • The Miscellaneous Material Specification Was Well Received by AMEC.  The Chairman, Bib Steffen, Is Requesting That If Anybody Has Additional Materials To Be Included, The Information Be Forwarded To Us.  Then We Will Begin The Balloting Process For The Draft To AMEC.  Hopefully, The Balloting Will Occur At The Next AMEC Meeting In 10/2005. • Fracture Control Handbook for Spacecraft Composite Structures (NASA-HDBK-5016) • The Handbook Was Prepared By James Chang of Aerospace Corporation Using Aerospace Format • Sent A Completed Draft Copy Of The Handbook And A Resolution Matrix In CD Form To Paul Gill For Him To Distribute To All NASA Centers For Review And Comments. • Was Requested to Convert to NASA Format. Mr. James Chang Has Agreed to Take On The Conversion Task. It Requires Additional $7K Funding.

9. APPLICATION NOTES FOR NASA PREFERRED STANDARDS • Submitted 29 Application Notes for FY2004 To NASA Technical Standards Program Office, MSFC.

10. JPL ITA APPROACH TO TECHNICAL STANDARDS • Chief Engineer Is The Technical Authority (TA) For Engineering Matters At JPL • Brian Muirhead Was Recently Appointed Chief Engineer • The TA Has The Authority, Responsibility, And Accountability To Establish, Monitor, And Approve Technical Requirements, Products And Policy • The Independent Technical Authority (ITA) Is A Function Within The Role Of The TA • Provides Checks And Balances On The Execution Of Technical Work Conducted In Support Of Mission-related Programs And Projects • Organizationally Do Not Report To The Product Line Management • Have a Direct Line To The Agency’s TA Via The Warrant Without Going Through Programs • Able To Charge To An Agency Service Pool Account (Being Worked For JPL)

11. TECHNICAL AUTHORITY AND WARRANT AT JPLINITIAL PHASE NASA Chief Engineer T. Bradley JPL Center Director C. Elachi Discipline Warrant Products/Systems Warrant Engineering & Science Director Discipline TWH: J. Beckman Deep Space Flight Systems Product TWH: T. Gavin JPL Chief Engineer Brian Muirhead NESC JPL Discipline TWH’s JPL Engineering Board Technical Div., Prog/Proj/Dir. CE’s including Product TWH for specific projects JPL Projects Delegated Warrant Authority Re-delegated Warrant Authority Communication, Support, Standards, Requirements, Issues, and Decisions

12. JPL ITA APPROACH TO TECHNICAL STANDARDS • Flight Project Practices (FPP) And Design Principles (DP) Set The Standards For All Work Done At JPL • Project Support Office Is Responsible For FPP And DP And The Compliance With Them • All Projects Are Required To Show Compliance Checked Through Assessments • Red Teams (Independent Review Teams) • Appointed By The ITA To Perform In-depth, Independent Technical Assessment Of Key Technical Issues In All Aspects Of Flight Project Effort • Standards Change Authority • Exceptions/Deviations Or Waivers From FPP And DP Require Risk-focused Technical Justification, Clear, and Unambiguous Documentation • Changes To FPP And DP Undergo A Broad Evaluation Process With Inputs From Project Manager, Engineering Line Management, And Safety And Mission Assurance Personnel • Requires Approval By The Responsible Director For, Director For Office Of Safety And Mission Success (OSMS) And The Associate Director For Flight Projects and Mission Success (FPMS)

13. JPL FLIGHT PROJECT PRACTICES(DocID 58032) • Three Document Classifications • Directive • Documents That Must Be Followed. • Policies, Requirements (Respond To Policies), Procedures (Implement Requirements) • Deviations Require Waivers. • Guidance • Helpful Aids, Not Mandatory That They Be Followed. • Guidelines, Standards And Specifications And Reference Materials Are Guidance Documents • Guidance Documents Are Not Required Unless Invoked By A Directive Document. • Deviations require Waivers • Waivers Would Be Against The Invoking Document Rather Than The Guidance Documents. • Organizational • Describe Structure Of The Institution • Role Statements, Position Description, And Charters • Not Subject To Waiver

14. JPL DESIGN PRINCIPLES CONCERNING THE USE OF STANDARDS(JPL D-17868) • The Requirements Of This Document Apply Equally To Spacecraft And Major Payloads And Instruments. • Flight System Design • Safety • All Elements Of The Flight System Shall Adhere To The Applicable Design Requirements Of JPL Standard For System Safety (D-560) • Design Philosophy • Use Of Standards - Industry And JPL Standards (H/W And S/W) Shall Be Considered In All Areas Of The Design To Reduce Cost/Risk E.G. Consultative Committee On Space Data Standards (CCSDS).  When Deviation From Standards Is Necessary And Risk Is Consciously Accepted, These Risks Shall Be Included In The Significant Risk List • Interfaces • Use Of Standards - Standards Shall Be Utilized In Defining HW/SW And SW/SW Interfaces Between The Flight Systems And The Ground, Between Flight Systems And Within A Flight System E.G. CCSDS For Telemetry And Command.

15. JPL DESIGN PRINCIPLES CONCERNING THE USE OF STANDARDS(CONTINUED) • Flight Software System Design • Use Of Standards - Flight Software Shall Employ Appropriate Laboratory Standards In Interfacing To Ground Subsystems Or Other Spacecraft Subsystems - E.G., CCSDS For Telemetry And Command. • Note:   For Flight/Ground Interfaces, The "Appropriate Laboratory Standards" Should Be Specified In An Interface Control Document That Specifies Each Interface. This Makes Each Interface Implementable, Testable, And Usable.

16. CURRENT JPL INTERNAL STANDARDS REVIEW PROCESS • NASA Technical Standards Called Out In Contract • Reviewed By Appropriate Project And/Or Program Offices • Draft Technical Standards Reviews Requested by NASA Technical Standards Working Group (NTSWG) • Reviewed By Appropriate Technical Specialists And/Or Line Managers • “Director For” Given All Technical Comments And Comment Resolutions Before “Sign-off” • Non-NASA Standards Proposed for Adoption as NASA Preferred Technical Standards • Reviewed By Appropriate Technical Specialists Or Already Widely In Use At JPL

17. ESTABLISHING AN AGENCY-WIDE REVIEW PROCESS • Assumption • It Is Assumed That The Agency-wide Review Process Would Primarily Entail Reviews By Programs And/Or Projects For New NASA Technical Standards • JPL Comments • Technical Specialists At JPL Are The Principal Reviewers For New Technical Standards • Technical Specialists Reside In Line Organizations And Provide Data, Information, Expertise For All Projects • Standards Are Classified As “Guidance” Documents And Are Not Mandatory • Project Implementation Plan Identifies The JPL And External Standards That Apply To The Task/Project
