Detail Design Process THEMIS MPDR PM 11/12/2003 3
Schedule Process q Phase B – Vendors & Subsystem Leads work in MS Project due to ease of use – MS Project will not meet the long term needs of the program – Current master schedule / Open Plan (Welcom s/w suite) • • • Converted into Open Plan Allows for the ingest, digest and output of both MS Project and PRIMAVERA Ability to link to accounting system Ability to perform complex resource scheduling Ability to perform Monte Carlo risk analysis – Phase B detail schedule • • Using interval milestones to drive program (i. e. completion of drawing package or start of s/w build 2) Based on Phase A information WBS Driven Vendors supply MS Project files driven by SOW – – – • ARDE Aerojet GDDS Planner performs logic check of schedules and assesses need dates based on the Phase A anchor dates and then loads this information into Open Plan – Reporting will continue in MS Project • • Final testing of system complete in November Easy conversion from Open Plan to MS Project THEMIS MPDR PM 11/12/2003 4
Schedule Process q Integration & Test Schedule – Based on input from GSFC pre-confirmation review • • Creating further detail for the I&T flow Emphasis on Instrument Integration Emphasis on Environmental Test program Including the “nitty-gritty” type activities Using 5 day work week / 8 hour days Applying resource loading / leveling Also assessing production planning and it is integrated with Work Order Authorization (WOA) system THEMIS MPDR PM 11/12/2003 5
CSR Schedule Contingency q Schedule contingency is driven by Long Lead Procurements: – – – q q q THEMIS MPDR PM 11/12/2003 Propellant Tanks RCS Transponder BAU • Single Board Computer • Power Control Electronics • SMEX/TRIANA Comp Card Base Panel Probe 1 is completed first and is the trail blazer for Probes 2 – 5 Baseline is 12 weeks of schedule contingency (60 working days) between Probe 1 Delivery and the start of Probe I&T The “A” Team consists of the full complement of the I&T Team. The “A” team builds Probe 1 and then bifurcates into two Teams to build Probes 2 -3 & Probes 4 -5 in parallel. A residual of the “A” team continues on with the environmental testing of Probes. Probe Carrier is built in parallel by a separate Mechanical Team and links up with Probes at test facility Schedule contingency at back end of program has been lumped into a full 60 days (4 W +4 W) based on direction from GSFC 6
Major Milestone Schedule #1 q General Assumptions – Five day work week with 8 hrs per shift – Exception to above rule will be TV/TB testing and major moves – I&T schedule constrained by Team availability starting with Probe 1 build – Weekends can be used to make up schedule prior to mission I&T THEMIS MPDR PM 11/12/2003 7
Summary Schedule THEMIS MPDR PM 11/12/2003 8
Major Milestone Schedule #2 Potential earlier delivery of Instruments allows earlier start of I&T Bus integration contingencies Currently working day to day scheduling flow with UCB THEMIS MPDR PM 11/12/2003 9
Major Milestone Schedule #3 Probe Carrier contingency is in parallel with Probe schedule contingency Probe #1 has significant slack at end of I&T Unused slack will be utilized for mission simulations (based on resource availability) THEMIS MPDR PM 11/12/2003 10
Critical Path Analysis q Project management philosophy – All items are potential critical path items unless they are managed properly • • Focus on the current critical path item Focus on delta between ‘slack’ and ‘contingency’ Develop strategies to minimize durations Simultaneously keeping all other items off the critical path with constant schedule vigilance and workarounds • Critical path defined as activity flow with < or = zero slack based on interval milestone dates • Pink path defined as activity flow with less than ten days of slack THEMIS MPDR PM 11/12/2003 11
Mission Level Critical Path THEMIS MPDR PM 11/12/2003 12
Critical Path Analysis Drill Down q Current critical path at Probe level – Base panel composite structure delivery to RCS vendor • This will subsequently drive availability of base panel for IDPU integration – Side panel composite structure delivery to Solar Array vendor • Since Solar Array is last item to be installed prior to start of Environmental test program it inherently has slack in current schedule – Overall structure deliveries are driven by thermal cycling & strength testing of each Probe prior to delivery to I&T q Probe Carrier is off the critical path – Built in parallel with Probes 1 – 5 – Has adequate schedule contingency q Flight software is off critical path – Using commercial processor boards and Engineering Development Unit THEMIS MPDR PM 11/12/2003 13

Summary Of Costs Probe & Probe Carrier THEMIS MPDR PM 11/12/2003 26
Cost Management @ Swales q General Tracking of Costs – Subsystem Leads responsible for monitoring all labor and material charges • Charge numbers are opened at the fifth WBS level – PM and Subsystem Leads review weekly spending via on-line reports • Cost data available weekly – Major subcontracts are Firm Fixed Price with $ Milestones consistent with SOW (exception to Hammers) – Contractors working via purchase order or cost-reimbursement, • invoice bi- monthly • PM sign off required prior to processing Phase B - Budgets versus actual spending worked at summary level q Phase C/D – Swales internal Performance Measurement System q – Budget Cost Work Schedule (BCWS) developed in Open Plan for each major subsystem – Budget Cost Work Performed (BCWP) calculated by statusing of Open Plan – Actual Cost Worked Performed (ACWP) compared to BCWS & BCWP to assess performance – Estimates To Complete (ETC) initiated for WBS elements projected to be > 10% of Budget At Completion (ITD + ETC) THEMIS MPDR PM 11/12/2003 27
Phase B Burn Rate q Labor Hours (as of 10/24/03) – Exceptional labor performance against original plan – Slower start up in staffing in some areas (Electrical Engineering) – On average we are using a more experience staff than we proposed resulting in efficiencies in design – Trend should level off consistent with cost proposal in next several months – Current labor savings will be used to buy down risk in phase C/D THEMIS MPDR PM 11/12/2003 28
Phase B Burn Rate q Subcontract/Material (as of 10/24/03) – Lag between billing and processing ~ 2 weeks • • Bills being processed ~ $705 K First invoices: Tanks, RCS, Ball, Hammers, Jupin – Outstanding commitments ~ $920 K – Slower ramp up of major subcontract • Hammers Company running true to original plan – Budget included $1. 3 M for electronics vendor - GDDS not on board yet THEMIS MPDR PM 11/12/2003 29
Current Open Risks q The Stoplight Report ranks all of the Open risks Update planned for December 2003 THEMIS MPDR PM 11/12/2003 30
Major Risk Areas q Separation System Design & Test – Number one risk for Probe & Probe Carrier going into / coming out of Phase B was Separation System • • • Move to more classical approach for Separation System (Marman Band) Reducing overall risk Will require more resources in order to achieve performance levels – Engineering Test program will begin in second quarter of 2004 q Antenna Design – A result of FAST Antenna not meeting THEMIS requirements embarked on antenna RF pattern study at Ball. • • • q Requires more NRE expenditures Recent analysis indicates that the geometry works Antenna currently not on critical path Single Board Computer – Flight Software issue (paging) with original baseline would have driven schedule and test program. • Move to Cold. Fire allowed for use of Commercial Cold. Fire board early on in FSW test program. – Cost reserves applied to lower long term risk on the program – Engineering Development Unit planned for second quarter of 2004 THEMIS MPDR PM 11/12/2003 31
Major Risk Areas q Long Lead Procurements – Tanks & RCS contracts are on track with substantial savings against original budgets – Thruster sizing increase reduces operational risk and increases burn efficiency q Magnetic & ESD Requirements – Continue to work magnetic & ESD requirements with UCB/UCLA – Final Solar Array pricing will be driven by magnetic cleanliness and ESD compliance q BAU Part Pricing – Continue to work design and EEE parts requirements – Final pricing of BAU will be driven by specific parts implementation q Quality Assurance Requirements Changes – Recent proposed changes to QA requirements particularly in parts area • Force re-opening of contract discussions with vendors • Cause significant schedule delays. • Result in an overall increase in costs to the program THEMIS MPDR PM 11/12/2003 32
