"We build systems like the Wright brothers built airplanes; build one, push it off the cliff, see if it flies; when it doesn't, run down the hill; pick up the pieces and build it again."
Gerald Weinberg

Successful roll-outs are often characterized by a user population which not only receives the product, but also receives the motivation, desire, and ability to use it successfully.
