“Prior to World War II, an American General

observing the British Royal Artillery on maneuvers

noted that the guns were served by seven men. 

Of these seven, one did nothing but stand at attention

while the other six readied and fired the piece. 

When he asked his British colleagues what the

seventh man was for, nobody knew.

Intrigued, he pursued the matter until he found out that in the days before trucks, the seventh man held the horses.

The horses had gone, but the organizational structure,

now obsolete, remained.”

(Brown and Weiner, 1984)
