Visualizing something before you do it allows you to feel what it feels like to do it. Admittedly, you don't have to visualize the recipe to make Moussaka. If you didn't turn the oven on, the moussaka could not be cooked. No doubt, many persons have used her recipe for Moussaka without first visualizing it. And, many persons have put bicycles together without great peace of mind.
Protocols have more to do with attitudes than with procedures or methods.
However, when someone does not take the trouble to cook carefully, their careless attitude manifests itself in the event of the meal. Changes in protocols have surprising institutional consequences. Though they seem minor adjustments in the system, they often turn the system on its head over a period of time. I have always been fascinated by one particular change in institutional protocol. Such a change would probably excite a riot and this possibility alerts us the significance of the original change.
