/krē-ˈā-shə-ˌni-zəm/
n. The (false) belief that large, innovative designs can be completely specified in advance and then painlessly magicked out of the void by the normal efforts of a team of normally talented programmers. In fact, experience has shown repeatedly that good designs arise only from evolutionary, exploratory interaction between one (or at most a small handful of) exceptionally able designer(s) and an active user population -- and that the first try at a big new idea is always wrong.
