““Those involved in the redesign process must know what they would do if they could do whatever they wanted. Such knowledge is essential if they are to set meaningful goals for the future. The outcome of such a design is idealized in the sense that the resulting system is ideal seeking, not ideal. It should be subject to continuous improvement with further experience and changing environments. The only certainty is that some of whatever we think we will want five or ten years from now will not be wanted then. Such a vision should be inspiring, a work of art. It should facilitate making short-run sacrifices for the sake of longer-run gains.””
