MISSION STATEMENT “(7)Monitoring and Trends Analysis – The CUC recommends that the CXC provide a higher level of oversight to the SI performance monitoring and trending analysis program to ensure that appropriate performance quantities are being tracked.” GOAL: Identify ANY changes in instrument performance before they occur. (Walkthrough example: ACIS gain) 12 January 2004 CXC Users Committee SOT/DAS
ISSUES Technical: Identification of specific, potential, changes Identification of indicators for each such change Calculation of quantities to provide the indication (the trended quantity) Assessment of the sensitivity of the trended quantity to Instrument change What quantities must be determined more precisely (than currently), so that we are sensitive to any changes? 12 January 2004 CXC Users CommitteeSOT/DAS
ISSUES CONT… Software: Database review Report generation Correlations and predictions Organizational: Who is the monitor of each quantity? How does the software get developed? How do we educate CXC to use the existing tools? 12 January 2004 CXC Users Committee SOT/DAS
IMPLEMENTATION PLAN Team is drawn from DOSS, CAL, SI IPI teams, FOT, project-wide Divide by subsystems: ACIS HRC LETG HETG HRMA ACA Other PCAD (e.g., IRU, fid lights and transfer, mounting stability, FSS Other spacecraft equipment (e.g., reaction wheels, jitter stability, optical bench, focus and translation, EPHIN) Other infrastructure (e.g., ACE, GOES, internet connectivity) List the quantities which may change Make two rank orders for each subsystem Likelihood of occurrence Effect of occurrence Group assesses what can/must/should be monitored KEY POINT: One person responsible for each identified quantity. 12 January 2004CXC Users Committee SOT/DAS
