But if you are leading a team under your direction, you must justify your change to them. Teammates need to understand why they are supposed to scrap work in one direction and turn the other way. Teammates need to be told their contributions have been valuable and that future contributions will be even more so. Teammates need to be appreciated, encouraged, and supported so that they do not burn out. Teammates need to understand the bigger picture so that they can have faith in you and follow along.
Executive orders and commands hurt your authority more than enforce it. If you choose to rule that way, tell everyone why you are making your decisions. If you do not take the time, no one will be on the same page. No one will see your point of view. Everyone will be lost and confused. You will have a mutiny on your hands.
