LCLS has high priority, high visibility, high likelihood of full funding

BES must get funding above its “line” to do LCLS without shutting down some facilities

BES is prepared to do this for LCLS IF we are ready

Response to Comments/RecommendationsMembers of the FAC had minor concerns about the organization chart as having a baroque appearance in that on the surface, lines of authority don’t appear to be that clear. However, throughout the course of the FAC meeting clear lines of responsibility and authority were in evidence and only a few issues on communication (notably between the physics requirements on the conventional facilities and the operations configurations and approaches) were apparent. Response: The LCLS organization chart has been revised to clarify roles and responsibilities.

LCLSProjectOrganization(Sep05)

The project should incorporate those risk or trade-off items identified in this and previous FAC meetings into the Project Risk Registry to ensure adequate tracking and resolution. The project may wish to also incorporate any such risk items cited in official DOE reviews as well.Response: The LCLS organization continues to use the Risk Registry on a monthly basis as a key management tool to proactively address its known risks. The undulator floor stability risk has now been retired as it has now been shown that expected stability issues can be addressed with the alignment systems and BBA at acceptable intervals.

The project is entering into its boost phase where it is undergoing its maximum gradient: staffing, effort and procurement. During this phase, the timeliness of decisions often becomes critical and delays can quickly accumulate that can impact the overall progress of the project without specific attention. This is a concern to the FAC as the decision making process is not transparent and may need to accelerate to ensure avoiding unnecessary delays. Response: The decision making process has been made more transparent with the Change Control Board (CCB). With the CD-2b (Approve Performance Baseline), LCLS has enacted the CCB to deal with technical, cost and schedule issues on a timely basis. The CCB forum ensures that decisions are communicated uniformly across the project and formally documented in a manner consistent with good configuration control. Since CD-2b (April 2005), LCLS has approved 77 changes to the project and allocated ~$7M of contingency to the baseline cost of the LCLS.

John N. Galayda


27 October 2005

The critical path of the project, likewise, may be extremely fluid during this phase and near critical paths can quickly become critical paths, and so those efforts which at present are not on the critical path, must understand that they can quickly become the pacing activities.Response: The LCLS has significantly increased its staffing since April 2005 and with that some time for assimilation of new staff into the project is required. The LCLS is now nearly complete on its staffing plan so the inefficiencies due to assimilation can be expected to drop off. Critical path is monitored regularly and has not shown any appreciable degradation since established at 215 days.

John N. Galayda


27 October 2005

…However, an insightful planning exercise is to evaluate all activities for early starts up to the point where all of the budget authorization (BA) in each fiscal year would be used. In addition, exceeding this optimistic BA plan by 5 to 10% would also be helpful in evaluating potential resource demands. This planning assures that there are “swing items” identified in order to accomplish other work if planned activities are delayed. If the project doesn’t have swing items identified to work in the available time and with the available BA, the CD-4 milestone may be at greater risk than necessary.

“Swing procurements” are procurements that can be advanced should budget become available due to delays in other areas. This is of primary importance between FY06 and FY07. Since civil construction sets the critical path, LCLS will plan to use its budget flexibility in this area to best advantage, based on advice from the Construction Manager.

John N. Galayda


27 October 2005

A useful plot that can illustrate this phenomenon, and serve as both a leading and lagging indicator, is the contingency as a percent of the estimate to complete (ETC) budget as a function of the percent of the project complete. Generally, this should be roughly a horizontal line above 20%. Early in the project life it would likely start out at a higher number and depending upon the remaining risks within a project, the percentage can also be less than 20%.Response: Currently, the LCLS holds ~32% contingency on work remaining. This number may fall lower as the conventional facilities estimates become more mature and LCLS approaches the start of construction.

John N. Galayda


27 October 2005

There is a need for a central database containing and controlling the complete configuration of the LCLS project.

Work has begun on defining the detailed needs of the central database effort for the LCLS project. An IT Manager (Andrea Chan from the SLAC SCS group) has been hired into the LCLS Division and bringing significant experience in setting up databases in a project environment. At the same time Sergei Chevtsov in the LCLS Controls Group has been looking at the relational database needs for the control system, in particular the RDB requirements for online modeling for the accelerator.

John N. Galayda


27 October 2005

The LCLS Project should consider giving the FAC access to the LCLS internal website. This would allow the FAC to view other reviews and important work that can have an impact on the scope and details of FAC meetings. It will also allow the LCLS Project to exploit the full potential of the FAC.LCLS is in the process of exploring a different data management system, which would make access control but the system is not likely to become operational in this calendar year. At present, LCLS is working with Kem Robinson to do it the hard way now or wait until the simpler solution is in place.
