This is probably necessary when you are ordering troops into battle, but it seems a bit out of place in a business world. Fear also makes administration and management one and the same. A really simple life for most managers. However, it does require a number of key managers to issue the orders. Anything short of that fails.
Fear secures some managers in their position.
On the other hand, the managers that issue orders change fairly frequently, as a flawed order is carried out with an unforeseen consequence. As a consequence the rule for managers is to not make any changes. Don't issue orders if you want to remain in your position. Fear also avoids the sometimes embarrassing questions from subordinates. This operates throughout the company.
