Trigger - BCWS and BCWP Cumulative BCWP/BCWS = 85% indicating little schedule slippage. Trigger Trigger - BCWS and BCWP Cumulative BCWP/BCWS = 85% indicating little schedule slippage. Trigger subsystem has completed BCWP/EAC = 22% of the project. Schedule slip for Muon Trigger boards corrected this year by new personnel Schedule slip for ASIC development corrected by securing vendor contract Obligation of ASICs under contract, not invoiced Corrected for DAQ attribution to Trigger US CMS DOE/NSF Review: April 11 -13, 2000 10

Trigger Resource Usage Engineering and Technical resources are compared to the people called out Trigger Resource Usage Engineering and Technical resources are compared to the people called out in the annual SOW. This tracking ensures that the needed labor is deployed. US CMS DOE/NSF Review: April 11 -13, 2000 11
