If I (GSC) may "butt in":
Is this (the place that you do all these iterations and things), is it the same place where you filled up all the walls of all the halls and all the corridors with PERT Charts that were utterly useless?
What is not scientific about that is that PERT Charts (based on the "PRECEDENCE" relationship) are indeed almost entirely useless in any system if the users do not adequately understand the significance of the various relationships that may inhere in the system under consideration. I.e.: what specifically does it mean in a system that one 'EVENT' or 'MILESTONE' precedes or follows another?
If people in the system are so naive that they believe PERT Charts by themselves can help them extract meaning out of a system, then they will never come to understand the system under consideration.
