And here I thought people become managers because they're actually great with people. So why does that imply that they should stop listening to their staff unless the staff can intuit their idiosyncratic communication preferences?
IOW, the advice is probably right given current realities, and I agree in general that giving an outline before going into excessive detail is a good practice, but I also feel that if an executive wants something from their staff, they should tell them exactly what they need and be prepared to listen to the experts. It should be in their interest after all.
