  6. PFP Responsibilities

  7. Contracting Phase C/D Contracts in place SSL and LASP/LPW independently contracted to GSFC for MAVEN PFP Internal Funds Transfers from MAVEN Project to GSFC/MAG IRAP/SWEA funded by CNES, contributed hardware to SSL IRAP formerly CESR Inter-agency agreement with Lawrence Berkeley Nartional Labs for SEP detector development SSL Manages PFP development in collaboration with MAVEN Project Office SSL Coordinates PFP Team Schedules, Planning, Interfaces, Technical Resources, Risk Management, etc. A common Instrument Manager at GSFC facilitates coordination of contracts, deliverables, funding, etc. No changes in this configuration since PDR

  8. Team Experience SSL has a long history of successful development of instrument suites: Wind 3DP (5), FAST (5), MO/MGS/LP MAG/ER (2), STEREO IMPACT (7*2), THEMIS (5*5) Team is experienced working together: SSL w/ GSFC, Acuna/Connerney, MAG: MO, MGS, LP, STEREO SSL w/ LASP, Ergun, LPW: FAST, THEMIS SSL w/IRAP/CESR, Reme/Sauvaud/Mazelle, ESAs: Giotto RPA, Wind 3DP, Cluster CIS, MO/MGS MAG/ER, STEREO IMPACT SWEA SSL w/ Lockheed Spacecraft: MGS, LP Centuries of experience building spaceflight instrumentation in the PFP team No changes in the team key players since PDR some additions at lower levels

  9. Staffing PFP Team fully staffed Consistent below planned FTE levels due to: RBSP issues which have pulled MAVEN team members away Shared staffing with other projects, resulting in unplanned efficiencies Some team members have been distracted by continuing responsibilities with RBSP EFW instruments SWIA/STATIC mechanical engineers Power converter design team Thermal engineer Work-arounds have had some success but SWIA/STATIC behind schedule in completing EM fabrication and test SWIA and STATIC still have plenty of schedule margin to delivery

  10. Workforce Status, by CAM Area 87% 107% 96% 69% 62% 62% 83% of plan over-all 44%

  16. PFP Instrument PDR RFAs All PFP pre-PDR Peer Review and PDR RFAs closed

  17. Pre-CDR PFP Engineering Peer Reviews A full set of PFP peer reviews was held including: SWEA at IRAP/CESR, 2011-03-28 LPW & EUV at LASP, 2011-04-25 MAG at GSFC, 2011-05-05 SEP, SWIA, STATIC, LPW Boom, PFDPU, FSW at SSL 2011-05-09 – 2011-05-11 Very helpful informal technical interchanges with independent review teams Concentrated on changes since PDR, Test & Analysis Results, Plans Materials, Attendance, RFAs, Reports, RFA Responses posted to MIS Still pending: Detailed FPGA peer reviews Supported by Project / GSFC

  18. Pre-CDR Peer Review RFAs • Peer reviews too recent to have made much progress in RFA closures • Plan to have all responses at least submitted by Mission CDR • Specific RFAs and responses to be discussed in subsystem presentations

  19. Management Metrics Schedule Schedule updated monthly at a minimum Provided monthly to Project Schedule slack (per instrument and critical path) Task slippage Historical problem spots Walk Around Financial Spending tracked monthly by WBS element (instrument) Cost vs Budget (spending rate and total) 533 provided monthly to Project Project starting EVM SSL contract is below the EVM threshold, but SSL will benefit from Project EVM analysis results based on SSL inputs Technical Resource margins updated monthly (mass, power, processor) Provided to Project as part of Monthly Status Report Project CCR process for changes to NTE Gold Rule Contingency levels maintained per development phase Risk Levels from Risk Management System, updated monthly Provided to Project as part of Monthly Status Report Technical Issues Gleaned from weekly team & instrument meetings Provided to Project as part of Monthly Status Report

  20. Configuration Management Project Configuration Management Plan defines Level 1 change control process Level 1 changes affect Project configured documents, resources, cost, schedule milestones, contractual items, risk PFP PM part of CCB process for changes impacting PFP PFP also participates in LM ECB process for changes impacting PFP Approved PFP Configuration Management Plan defines Level 2 change control process PFP PM chairs PFP CCB Determines what changes need to be elevated to Level 1 Discusses any marginal changes with Project to determine classification Approves changes that are Level 2 Maintains configured database of documents on ftp site PFP PM delegates lower level change authority to leads Changes that don’t impact resources, configured items, level 4 requirements, interfaces, cost, or schedule

  21. Risk Management Project Risk Management Plan describes Project-Level system Approved PFP Risk Management Plan describes how PFP Risk Management Processes work Supports Project Risk Management Process Collects risk inputs from all members of the PFP team on a monthly basis Identifies Risk Areas for PFP mitigation or elevation to the Project level Tracks risks to closure LASP tracks and reports LASP/LPW risks separately per their plan FSW tracks software risks separately and reports to PM for possible inclusion with other risks

  22. Top Risks

  23. Risks List

  24. PFP Schedule Maintenance PFP Schedules maintained by institution SSL, LASP/LPW, GSFC/MAG SSL schedule includes CESR/IRAP Delivered monthly to Project for integration into MAVEN IMS Linked by fixed milestones which cannot be changed without by all parties affected SSL+CESR Schedule contains ~1300 tasks GSFC Schedule contains ~100 tasks SSL schedule maintained by dedicated scheduler Polls instrument team weekly on progress Coordinates with GSFC, CESR, LASP Provides reports to PM, GSFC Linked to EVM system by an agreed upon set of costed milestones

  25. MAVEN PFP Schedule Instrument CDR May 23-25 2011 Mission CDR July 11-15 2011 PFP PER May 2012 PFP PSR, Delivery November 2012 Launch November 2013 Arrive at Mars September 2014 End on nominal mission October 2015

  26. Schedule Summary, CDR to Delivery

  27. Schedule Summary, CDR to Delivery

  28. Schedule Margins FM Instrument deliveries to PFP Integration margin MAG – 7.4 weeks (was 12.4 weeks at PDR) LPW – 8.2 weeks (was 11.4 weeks at PDR) Includes 2.2 weeks to delivery from LASP plus 6 weeks to Package I&T SEP – 10.4 weeks (same as PDR) SWEA – 9.4 weeks (was 11.4 weeks at PDR) SWIA – 9.8 weeks (was 10.4 weeks at PDR) STATIC – 7.4 weeks (was 10.4 weeks at PDR) PFDPU – 9 weeks (was 11.4 weeks at PDR) PFP Integration to Ship margin 10.6 weeks increased from 4 weeks at PDR due to later delivery requirement So 18 weeks total margin CDR-Delivery on the critical path Was 14.4 weeks at PDR (plus 4.4 weeks pre-CDR margin) Out of 16 months Critical Path currently through STATIC due to delays in completing EM fab & test All schedule margin/slack is funded

  29. Schedule Status Some instrument EM assembly/test still to be completed Especially SWIA, STATIC Includes SWIA/STATIC Attenuator life test, instrument calibrations Includes STATIC ‘Worst Case Test’ voltage-temperature margin test 18 of 28 parts stress analyses still to be completed Detailed Board-level thermal analysis remain to be completed for all boards dissipating significant power (>0.5W) including: REG, IIB, DCB, DAP; SWIA Preamp, Power converters; STATIC Digital, TDC, Power Converters Feedback from EM testing to power converter requirements not complete Full-up PFP integrated package test Have completed all individual instrument to PFDPU integration, just not all at once PFDPU board mechanical PWB stress analysis to be finalized All of this will be completed and results delivered by Mission CDR with the following exceptions: SWIA, STATIC Calibrations SWIA, STATIC Attenuator Life test These will be completed by mid August FM schedule assumes flight build not started until these tasks are completed on an instrument-by-instrument basis i.e. SEP can start flight fab even though STATIC is not done with calibration

  30. Drawing Status EM Drawings nearly 100% complete Missing: MAG Thermal blanket, assembly drawing PFDPU mechanical (pending MDM connector change) PFDPU Flight-format FPGA daughter board layout (in review) The majority of EM drawings will be converted to FM drawings with some minor exceptions as a result of EM assembly and test FM Drawing release pending completion of EM testing in most cases
