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.
