System engineering resource loaded schedule is controlled through P3.Design process:
Interface Control Documents specify which group has responsibility for each system.Physics Requirements Documents are written by the LCLS Physics group specifying subsystem needs.Engineering group holds Design Reviews, and writes Engineering Specification Documents to detail how the PRD is to be satisfied.
Physicists and Engineers sign-off on component assembly and testing prior to installation.

Start Up Test Planning
15LCLS EIR, 10/9/07D. Schultz
As installation is approaching, systems are well defined.Installation costs
Based on experience in 2006 Injector installation. Hardware install estimate done top-down and bottom-up.
Based on experience on undulator prototype at ANL.Cable plant install estimated using R.S. Means.
Fabrication/procurementCosts based on quotes and experience with prototypes at SLAC and ANL.
Engineering and CommissioningTimetable for completion well understood.
E-Beams Systems Cost Estimation

Risk Assessment
Design maturity and cost/schedule exposure are used in the contingency analysis for all DCE activities.Major risks are identified as Risk Registry entries, and assessed and maintained by the System Manager.The Senior Management team reviews the Registry monthly.
Summary of E-Beams Systems entries:Linac (2)
Risk: Linac diagnostics may need to be enhanced to have sufficient sensitivity for FEL commissioning.
Mitigation: The upcoming BC2 commissioning will determine if an upgrade is warranted.
17LCLS EIR, 10/9/07D. Schultz
Risk registry
Summary of entries (cont.):Undulator (3)
The assembly of the Undulator Girders is a pacing item for Undulator commissioning. Several components from ANL are close to being the limiting factor
Risk: Any rework or modification of parts at SLAC will delay girder assembly.
Mitigation: We have multiple weekly video meetings with ANL and quarterly Undulator collaboration meetings to ensure coordination.Integration engineers at ANL and at SLAC have been established to coordinate the receipt and assembly.

Electron Beams Systems are approaching final installation.Systems are well defined,
Based on Project documentation.Resource loaded schedule in P3.Costs have a solid basis.
The start up test plan is based on the successful turn-on of the LCLS Injector.Identified risks are being controlled.
