Value Management - XCS uses outside expert vendors for critical procurements – e. g. Diffractometer, Large Angle Detector Mover XCS utilizes expertise in outside labs for specialized equipment – e. g. Split & Delay, Detector XCS uses components designed for other LUSI instruments – e. g. XPP Tables XCS uses components designed for other SLAC departments – e. g. SSRL Rafts in XRT LUSI places XCS last in schedule allows XCS to choose the best of recent designs in XCS construction. LUSI DOE Review Aug 20, 2008 X-ray Correlation Spectroscopy p. 24 (WBS 1. 4) A.

Risk Identification & Mitigation Diffractometer System Diffractometer & LA-Detector Mover sub-systems share similar risks. Systems are either vendor build or design/build Risk Assessment: schedule delay : late placement of PO to vendor. Seek pre-approval of elements prior to BA. Insure all stake holders are aware of status and their requirements. Closely track document flow to insure timely sign-off / forwarding. schedule delay: late vendor engineer-design review approval (LAD Mover) Insure initial vendor buy in of timeline. Closely track vendor progress during design stage. Establish contact with sub-vendors to insure timely deliveries. Complete periodic spot review of designs to insure suitability. schedule delay: late fabrication-assembly. Request periodic status updates. Start partial acceptance testing as soon as suitable sub-assemblies are completed. schedule delay : requirements not met during vendor site acceptance testing. Replace individually deficient element. Temporarily immobilize deficient element. Deploy interim hardware with reduced capability. Technical requirements not met in commissioning. Investigate alternative hardware for interim use.
