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

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.

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

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.

Summary
Instrument concept is based on proven developments made at 3rd
generation Synchrotron Radiation sources
Scope of instrument defined
Resource loaded schedule developed
Many of the materials estimates come from vendor quotations, catalogs,
previous orders or work performed by other LUSI instrument teams
The XCS Critical Path is dominated by late start of engineering work and
DCO procurement; constrained by funding profile
Preliminary design of key components is well advanced
Quantify types of components
Estimate component costs
Specify acquisition methods
Establish baseline schedule
XCS is ready for CD2 !
