Development of the DESI Project Schedule Integrated project

Development of the DESI Project Schedule • Integrated project schedule originally developed in MS Project at CD-1 and migrated to Primavera P 6 prior to CD 2 • Schedule maintained in Primavera P 6. Performance measurement baseline maintained in Cobra • Performance management is performed in LBNL’s certified EVMS system (DESI-0898) • Baseline schedule and time-phased budgets were established following CD 2, September 2015 – EVMS data generated and reviewed monthly – Six Baseline changes approved through March, 2016 • Formal reporting into PARS-2 since CD-2 approval • P 6 schedule is used for detailed tracking and management of the DESI project for both DOE and Non.
