Sample goniometer is critical path item for XPP
Goniometer is long lead procurement
Seek procurement authorization before CD-3A
XPP Schedule has sample goniometer at 75 days float
~500 days duration / 75 days float = ~6.5 effort day per day of float

Risk Identification & Mitigation
Diffractometer System
Sample Goniometer & Detector Mover sub-systems share similar risks.
Both systems are design –build by vendor.
Both systems use same LUSI specified eng-design-fab flow.
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.
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.
Temporally immobilize deficient element.
Deploy interim hardware with reduced capability.
Technical requirements not met in commissioning.
Investigate alternative hardware for interim use.

Summary
XPP designs are mature and the instrument
team has made significant design progress
since the CD-1 Review
XPP has an established design with a
consistent cost estimate. Over 80% of the
materials estimates came from vendor
quotations, catalogs, or previous orders
Critical Path “float” reasonable for total
schedule duration
Significant effort , and progress, to date in
technical system risk reduction.
XPP ready for CD2 approval.
