Engineering – Milestone Look-Ahead Near Term Limit design effort to fit within FY09 funding constraint Milestones Through End CY08 Complete XCS ESDs Other System Dependent Design XCS uses designs created by other LUSI WBS sections (1.5 Diagnostics/Common Optics and 1.6 Controls) XCS must participate in design reviews of components for other systems to assure usability in the XCS instrument XCS must monitor design activities at XCS instrument interface boundaries to assure connectivity and integration Page

Value Management - XCS 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. Page

Procurement Strategy A variety of sources are used to design – build - install XCS components based on experience and cost (coded in P3). Previous designs and Off-The-Shelf components are used whenever available. Page

Cost & Schedule BOE & Manpower Loaded Schedule developed in the same way as the other LUSI instruments XCS budget stats Peak spending = CY11 SLAC Labor = ~56% SLAC Non-Labor = ~44% Page

Cost & Schedule Durations Person quarter = 444h Person year = 1776h Person month = 148h Page

XCS Schedule Critical Path Driving Milestones LL Approval, CD-3, CD-4 & Funding M/S Delayed Design Start due to Funding XCS Path moves to DCO Procurements XCS Instrument Installation effort Page

XCS Schedule Critical Path Procurement of DCO components delayed to FY11 due to funding Page

XCS Schedule Critical Path XCS critical path includes Delay in support design due to funding DCO procurement, delayed by funding Instrument installation, requires DCO components Minimum float is 80 days Due to funding limitations, XCS schedule is essentially compressed to two years instead of three Without funding limitations, XCS float is 182 days Schedule risk could be reduced by funding XCS design and procurements earlier All XCS Scope is CD4 deliverable Page

Risk Identification LUSI – XPP risk addressed per “LCLS Risk Management Plan” document number PMD 1.1-002-R4 WBS items with risk analysis – risk severity of medium or high forwarded for inclusion in LUSI Risk Registry Page

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.
