Q: How many bureaucrats does it take to screw in a light bulb?
A: Two. One to assure everyone that everything possible is being
done while the other screws the bulb into the water faucet.
An architect's first work is apt to be spare and clean. He knows
he doesn't know what he's doing, so he does it carefully and with great
restraint.
As he designs the first work, frill after frill and embellishment
after embellishment occur to him. These get stored away to be used "next
time." Sooner or later the first system is finished, and the architect,
with firm confidence and a demonstrated mastery of that class of systems,
is ready to build a second system.
This second is the most dangerous system a man ever designs.
When he does his third and later ones, his prior experiences will
confirm each other as to the general characteristics of such systems,
and their differences will identify those parts of his experience that
are particular and not generalizable.
The general tendency is to over-design the second system, using
all the ideas and frills that were cautiously sidetracked on the first
one. The result, as Ovid says, is a "big pile."
-- Frederick Brooks, "The Mythical Man Month"
