In most projects, the first system built is（71） usable. Itmay be too slow, too big, awkward to use, or all three. There is no （72） but to startagain, smarting but smarter, and build a redesigned version in which theseproblems are solved. The discard and （73） may be done in one lump, or it may be done piece-by-piece. But alllarge-system experience shows that it will be done.

Delivering that throwaway to customers buys time, but it does soonly at the （75） of agony （极大痛苦）for the user, distraction for the builders while they do theredesign, and a bad reputation for the product that the best redesign will findhard to live down.

Hence plan to throw one away; you will,anyhow.
