  2. This page intentionally left blank

  3. Introductions • Recognition of the Review Committee and Gemini • Introductions

  4. Overview of the Presentation • We will start with the current status of the project including an overview of the project schedule, summary of the opto-mechanical design, electrical design, systems design, and the cost performance to date. • The summary of the committee report items will include an issues compliance matrix, and address specific committee concerns. • In the project overview section we will present both the plan to the RR and the plan to completion. A discussion of the remaining issues between Gemini and NOAO is included. • Project management will cover the GNIRS project organization, the schedule, critical path, remaining capital and labor costs, cost performance tracking, reporting, etc. • The new GNIRS configuration will be presented in summary to familiarize the committee with the new instrument design. We will present examples of the requirements flowdown process, the top level configuration, and system integration. • Risk ID and mitigation is planned for the second day and will address all risk items previously pointed out by the committee plus additional items related to the new design, and the plan to mitigate these risks. • Sidney Wolff will then conclude our presentations and we will adjourn for the committee to caucus.

  7. Committee Charge • What is NOAO’s current cost estimate to complete GNIRS and on what schedule? • Is this estimate consistent with NOAO’s planned resources over the duration of the GNIRS project? • Have the technical issues (AURA report attached for reference) identified by the AURA review committee been addressed adequately to permit continuation of GNIRS? • Does NOAO now have in place an appropriate management structure to track, plan, and control resources to ensure that GNIRS will be delivered on time and budget? • Are there any approaches to designing and fabricating GNIRS that can significantly accelerate the planned delivery, e.g., through the injection of additional NOAO resources, outsourcing the fabrication of components, etc.? • Have all contractual matters involving out of scope work, definition of work, and interfacing requirements been settled with IGPO?

  8. GNIRS Reprogramming Addresses All Committee Report Items • USGP WPM meets nearly daily with PM • All information USGP requests is provided, in the format requested • USGP attends all weekly staff meetings, notified of all other meetings in advance • PM solicits USGP input frequently • More involvement of USGP in daily GNIRS activities • Actively soliciting IGPO input • Responsive to IGPO concerns • More direct communication with NOAO Director • Between Project and USGP WPM • Systems engineering is a critical capability • Meets all technical requirements • Meets original weight requirements

  9. GNIRS Reprogramming Addresses All Committee Report Items • Clearly defined NOAO/USGP relationship • We have a new philosophy of working • IGPO is a customer • Our project is open (e.g., web site) • We have a new management structure • Full time Project Manager who reports directly to NOAO Director • USGP WPM reports to NOAO Director • GNIRS has new engineering & systems team • Engineers do the design • Formed systems engineering team (3 scientists plus PM) • GNIRS is a new configuration • Optical design is essentially intact • Repackaged or redesigned entire instrument • Addresses all technical issues in the AURA committee report

  11. SECTION II Summary of Committee Report Items

  12. Committee Report Identified 9 Basic Concerns • New design addresses technical issues • Systems engineering guided the design effort • We have addressed the risk items and have a mitigation plan • We have the best engineers in the organization on the project • The project has high priority and reports directly to Sidney Wolff • The IFU and OIWFS interfaces and integration have been addressed • The instrument integration will be led by the project scientists • Project Management shortcomings have been addressed • We are confident the instrument will meet requirements

  13. Committee Report Identified 9 Basic Concerns • Unresolved technical issues • No rigorous requirements flow down • Lack of risk ID and mitigation plan • Capability of engineering staff • Organizational hierarchy • IFU and OIWFS integration issues • Lines of responsibility for systems integration • Project management • Overall technical capabilities of the GNIRS instrument

  19. SECTION III Current Status of the GNIRS Project

  20. Activities Chart to Restart Review • Major milestones: • 1/18 Hawaii review • 2/10 OIWFS ICD deficiencies identified • 3/9 Durham IFU meeting • 3/15 Interim review #1 • 5/25 Interim review #2 • 6/21 Baseline completed for RR • 6/1,7/2 ICD reviews • 7/20-21 Restart Review • Major activities: • Preliminary opto-mechanical layout • Cold motor T&E • Final configuration design • Requirements flowdown • Electrical systems design • Restart Reviewpreparation

  21. Activities Chart to Restart Review

  22. Projected Cost Performance Through July 31, 1999 • Labor budget: $443.8K • Projected thru 8/1: $337.1K • Capital budget: $ 59.0K • Projected thru 8/1: $ 75.0K • Total under plan $ 90.7K

  23. Restart Review work is approximately 89% complete • Budgeted labor dollars through RR is 76% spent • RR budgeted non-payroll capital is 127% spent • Performance (1/1-7/30) • BCWS = $443.8K (budgeted cost of work scheduled) • BCWP = $394.9K (budgeted cost of work performed, total project to RR) • ACWP = $337.1K (actual cost of work performed total project to RR) • CPI = 1.17 (cost performance index = BCWP/ACWP) • SPI = 0.89 (schedule performance index = BCWP/BCWS) • Project is 11% behind schedule (overall to RR) • Critical path is 19% behind schedule (opto-mechanical design) • Schedule to completion takes this into account • Under-spending reflects actual costs vs average rate planning • FTE loading very close to prediction • Cost delta’s related to actual salary rated vs planning numbers

  24. Reviews Prior to Restart Review • Virtual reviews solicited from • Tom O’Brien, OSU • Donald Pettie, ROE • Bobby Ulich, Kaman Aerospace • In-process reviews: • March 15 • May 25

  25. Engineering Design will Finish December ‘99 • Under-estimated the opto-mechanical design task • OIWFS more complicated than anticipated • Design is mature enough to qualify for this review • Three in-process reviews held • Virtual reviews solicited from individuals outside NOAO • Reviewed by NSF and AURA in May ‘99

  26. Design Status Systems • Done by the systems engineering team led by Jay Elias • Primary vehicle is the System Design Note (SDN) • Major way of communicating requirements and analysis/test results • Can be initiated by any member of the GNIRS team • Not restricted to the requirements definition • Produced for every level of the design Optical-Mechanical • Main optical bench, bulkhead structure, and thermal/structural interfaces are on critical path of the project • All mechanisms have been addressed and preliminary designs exist • More work to do on all • Final designs will be tied to results of the drive prototyping • Optical design update is complete • Only adjustments in camera lens spacing, etc., and stray light analysis remain • The preliminary mechanical design will be complete in the last quarter of this year Electrical • Details on specifics of connector panels and wiring remain to be defined • All major electrical interfaces are defined and specified • Includes planning for the integration of OIWFS hardware

  27. Design Status • Systems Engineering and Requirements Flowdown Activity is 95% complete • Preliminary Opto-Mechanical Design is 81% Complete • Preliminary Electrical Design is 75% Complete
