There is nothing in this world constant but inconstancy．--SWIFT
Project after project designs a set of algorithms and then plunges into construction of customer-deliverable software on a schedule that demands delivery of the first thing built．
In most projects,the first system built is （71） usable,It may be too slow,too big,awkward to use,or all three．There is no （72） but to start again,smarting but smarter,and build a redesigned version in which these problems are solved．The discard and （73） 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 system to throw away,for even the best planning is not so omniscient（全知的）as to get it right 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 （74）,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 （75） of agony（极大痛苦）for the user,distraction for the builders while they do the redesign,and a bad reputation for the product that best redesign will find hard to live down．
Hence plan to throw one away;you will,anyhow．

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. Where a new system conceptor new technology is used, one has to build a system to throw away, for eventhe best planning is not so omniscient （全知的） as to get it right the first time.
The management question, therefore, is notwhether to build a pilot system and throw it away. You will do that. The onlyquestion is whether to plan in advance to build a （74） , or topromise to deliver the throwaway to customers. Seen this way, the answer ismuch clearer. 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.

Due to a constantly __(66)__ environment, a poor understanding of the user’s needs and preferences, as well as a __(67)__ of willingness to modify __(68)__ organizational structures and decision models, the full economic potential of Web Information Systems (WIS) has not been realized by now. The data object types of the __(69)__ meta. model, the Extended World Wide Web Design Technique (eW3DT), provide hypertext designers __(70)__ a conceptual, user-centric framework and graphical notation for the construction of both, __(71)__ and customized models, during the software development __(72)__ of commercial WIS. A reference model as a normative concept represents an abstraction of a __(73)__ company, its functional units, or its (Web) Information Systems and is intended to streamline the design and implementation of complex applications at __(74)__ costs. As precondition for pursuing a partial globalization strategy, eW3DT __(75)__ between technical and content-specific responsibilities for designing, implementing, and maintaining WIS.
