Processes should be like Jockeys
Processes should be like Jockeys, light-weight, minimum overhead, and producing maximum results.
The horses could run faster without the Jockeys but not necessarily in the right direction. Lane jumping, collisions, or running in opposite direction could happen without the jockeys.
Processes should ensure that whatever is happening or whatever is supposed to happen, happens in the right way. At the same time processes should be light-weight, if the jockey is too heavy, it would slow down the horse.
