GREAT ADVANCES DO NOT COME OUT OF SYSTEMS DESIGNED TO PRODUCE GREAT ADVANCES. - John Gall

The field of Architecture has given rise to a second major principle relating to the Life Cycle of Systems. This principle has emerged from the observation that temporary buildings erected to house Navy personnel in World War I continued to see yeoman service in World War II as well as in subsequent ventures, and are now a permanent, if fading, feature of Constitution Avenue in Washington... We conclude: A temporary patch will very likely be permanent.

A system represents someone's solution to a problem. The system doesn't solve the problem.
