there is nothing in this world constant but inconstancy.-SWIFT
Project after project designs a set of algorithms and then plunges intoconstruction of customer-deliverable software on a schedule that demands delivery of the first thing built.
In most projects, the first system built is (1) usable. It may be too slow, too big , awkward to use, or all three. There is no (2 ) but to start again, smarting but smarter and build a redesigned version in which these problems are solved. The discard and (3) may be done in one lump, or it may be done piece-by-piece. But all large-system experience shows that it will be done. Where a new system concept or new technology is used, one has to build a syste m to throw away, for even the best
planning is not so omniscient (全知的) as to get it fight the first time.
the management question, therefore, is not whether to build a pilot system and throw it away. You will do that. The only question is whether to plan in advance to build a (4).or to promise to deliver the throwaway to customers. Seen this way, the answer is much clearer. Delivering that throwaway to customers buys time, but it does so only at the (5) of agony (極大痛苦) for the user, distraction for the builders while they do the redesign, and a bad..reputation for the product that the best redesign will find hard to live down.
Henceplanto throw one away; you will,anyhow.
