I still have great difficulty in getting work estimates. I have a small group of developers who understand the concept, but everyone else, including my manager (who, amazingly enough, used to be a PM) still want to give me duration-only estimates. As in: (this may take me an hour, but) “give me a week to get it done”. I don’t know how write a dynamic Project plan that will give me accurate forecasted finish dates with no work estimates. Frustrating…..
