23. 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

24. 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

25. 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

26. 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

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

28. 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

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

30. 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

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

32. 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.
