16. Random Points • We had some very early help in getting our plan right from Mark Heron and Dave Gurd. They identified key budget areas that were missing. • Identifying areas of development early, makes it possible to make a difference for this project. There is only 3 years from start of the project to start of commissioning • Getting requirements from physicists is one of the more challenging parts of a project. We are most successful by talking to the control groups at other similar projects.

17. Conclusions • Our capabilities are defined by our group, and we have been very fortunate to attract such great talent. • The developments that we have undertaken are going well in hardware, relational database tools, and high level application architecture. These could be useful in other environments. • The resources available to meet the demands of modern facilities are such that we must expand the areas where we collaborate: hardware, physics applications, experiment control, analysis, etc…
