Overview Cost to Complete

This document provides an overview of the cost and schedule to complete the GLAST Large Area Telescope (LAT) project, along with the necessary actions to control costs and meet project goals. It includes updated cost estimates, a revised schedule for shipping the instrument to NRL, and the need for a credible 2-month float in January.

  2. Rebaseline schedule • Subsystem managers input Done • Review Cost to Complete • Subsystem managers meeting November 17, 2004 • Materials ready for DOE November 24, 2004 • GLAST Mission Office Monthly December 2, 2004 • LAT JOG Telecon December 6, 2004 • LAT Baseline review at DOE Headquarters December 17, 2004 • LAT JOG at NASA-HQ TBD

  4. DRAFT LAT Schedule – No float

  5. Slip in the 16 months since rebaseline

  6. DRAFT October Plan

  7. Draft Cost Estimate

  8. Summary of existing inputs • Increase in fabrication phase funding $ 24 Million • New fabrication phase funding $160 Million • New cost to complete as of September 30 $ 41 Million • New contingency $ 5.2 Million • Assumed schedule • Last Tracker module complete May 2005 • Ship LAT to NRL September 2005 • Ship LAT to Observatory Integration January 2006 • 2 months float March 2006 • Launch May 2007 • Cost risk is primarily schedule risk

  9. Issues • Can not let subsystem schedules slip • Each subsystem needs to execute its own plan • Even if off the critical path, each slip is causing major cost growth • Need to control costs • Can not continue to process CCB actions for costs that have already occurred • Too many surprises • Must ramp down staffing • Descope options

  10. Goals for this meeting • Each subsystem manager should understand what is required to update his cost estimate and the supporting text • Develop a cost to complete for the instrument to be used as the basis for the rebaseline • Develop a schedule for shipping the instrument to NRL • Needs a credible 2 months of float in January when the rebaseline is incorporated
