Also, if you really must build a system, by all means remember the Systems Law of Gravity, otherwise known as the Vector Theory of Systems:
Systems Run Best When Designed To Run Downhill.
In human terms, this means working with human tendencies rather than against them. For example, a state-run lottery flourishes even in times of economic depression because its function is aligned with the basic human instinct to gamble a small stake in hopes of a large reward. The public school system, on the other hand, although founded with the highest and most altruistic goals in mind, remains in a state of chronic failure because it violates the human principle of spontaneity. It goes against the grain, and therefore it does not ever really succeed.
