It is foolish to plan for the best by just hoping to get the best resources, productivity and enthusiasm while working on a project. It is absolutely possible that we might get to work with the worst kind of resources whose productivity is low and is less enthusiastic. In such a situation if our planning was with the best, we will be left with nothing to do. But, if we plan for the worst, we can work with any kind of resources.
