23-Nov-1999STScI Projects Monthly Status Review4 of 8 SpaceTelescopeScienceInstitute COS Status Report for period December, 1998 to November, 1999 CHANGES TO BASELINE PLAN No changes made to the plan due to slips or advancements in milestone dates Changes made to the plan from applying “lessons learned” : Created written Project Plan to describe program and clarify organizational roles Use successful development methodologies begun with ACS: 1) clear requirements definition and design phases up front 2) phased scheduling system development prioritized development schedule to include science operations of most importance in first phases 3) end-to-end testing based on ACS model 4) apply existing strengths to process via working groups COWG CALWG 5) system development and test status tracking matrix Contingency planning: implications of inclusion of COS on SM3b manifest action: assessing impacts on current development schedule COS Plan Status

23-Nov-1999STScI Projects Monthly Status Review5 of 8 SpaceTelescopeScienceInstitute COS Status Report for period December, 1998 to November, 1999 TOP ISSUES & CONCERNS RED issues: none YELLOW issues: 1) OP-01 finalization: COWG meetings on tight schedule for definition of Phase I capabilities identified early 1999; affects requirements definition for scheduling system development specific COWG schedule and agenda set September, presently on schedule; integrated schedule meetings commenced November, ) Target Acquisition: COS IDT methodology must be confirmed identified June, 1999; affects late Phase I scheduling system development appropriate modeling to confirm schemes presently in definition by IDT, but modeling yet to be performed offer of STScI expertise accepted and is part of process

23-Nov-1999STScI Projects Monthly Status Review6 of 8 SpaceTelescopeScienceInstitute COS Status Report for period December, 1998 to November, 1999 TOP ISSUES & CONCERNS (continued) GREEN issues: 1) MOU on requirements and work schedule to provide OPUS/MAST capability to IDT at COS TV by 1 Oct 2001 identified June, 1999; resolved Sept., 1999 after numerous direct consultations with COS IDT and with affected STScI division heads and branch chiefs avoids duplication of development effort and facilities cost; promotes future calibration/analysis efficiencies 2) need to know our internal STScI counterparts - with whom do we work?; need to meet to coordinate effort; affects overall development quality and efficiency identified Oct 1999; monthly integrated schedule meetings commenced 18 Nov 1999
