Design process, included in Project P3 scheduleInterface Control Documents specify which group has responsibility for each systemPhysics Requirements Documents are written by the LCLS Physics group specifying subsystem needsEngineering group holds Design Reviews, and writes Engineering Specification Documents to detail how each PRD is to be satisfied
Physicists and Engineers approve component assembly and testing prior to installation

Risks
Late changes to design requirements
Atomic Physics design not finalized
Radiation Physics requirements not final
<$200k, <4mo impact
Mitigate through formal design process
AMO design will be finalized in 3 months

Risks 2
Offset mirror system Mirrors are specialized long-lead procurements
Precision mirror controls still in development
<$300k, <6mo impact
Mitigate through generous schedule

Summary
XTOD is in procurement phase, XES still in design
XTOD and XES have suffered delays due to CR
New plan allows recovery with extended project,
phased completion
Risks to major project milestones are low
