  32. Milestones… (continued) Global Design Effort

  33. How to define a Work Package? The plan has evolved from an original version that was clearly unmanageable, to one that “feels” manageable. The characteristics that make it feel manageable are: • Each Work Package contains one or more (fairly) continuous activities (though not necessarily at a constant level of effort). • The number of parallel activities within each Work Package is minimised; ideally, there is only one activity going on within each Work Package at any given time. • The number of points of “Critical Information Exchange” is minimised. Note: there is no explicit distinction made between activities on different points of the scale from basic R&D (e.g. electron cloud mitigation) to design of relatively-straightforward components (e.g. quadrupoles).

  34. Next Steps • Complete the list of Tasks and Milestones, filling in all the dependencies and connections. • Match the Resources to the Work Packages. • This will provide a reality check. • Information on Damping Rings resources and activities has recently been updated: we have (most of) the information that we need. • Meanwhile: discuss all this with the EDR Task Force… Global Design Effort
