creationism
 n.

    The (false) belief that large, innovative software 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. Unfortunately,
    because these truths don't fit the planning models beloved of management,
    they are generally ignored.
