Milestone 2 Dependencies

Assuming that I go forth with the phases described in my last post (and I am assuming that), there is a certain order in which the phases must be completed.  That is, until I finish Phase 2.  Then I'll have a choice between Phases 3, 4, and 5, which all depend on 2 but don't necessarily depend on each other.  I have some time to think about which I'll do first because I won't arrive at that particular decision point for quite a while still.

I expect this (barely adequate) Pert chart to guide some of my decisions as I work my way through this milestone.

Six phases in five weeks.  Can it be done?  That's not a rhetorical question!
