tdracer, very well put .

one of the biggest is that they have a tendency to miss the forest because they are too busy examining the trees - they often miss the big picture.
this is unfortunately valid for many organisations as we have decided to slice the forest into bits and each tree has now his own experts and specialists, which often do not communicate much with one another. And the person in charge of the forest is in fact just listening to experts of individual trees .
I have also seen this reverse thinking , we have a goal or a paragdim , so give me the scientific facts to prove it is feasible and that I am right. And among the trees you always will find an expert with the solution you like ..
