o In the beginning the particular need to be satisfied may be quite well-defined o Here are two examples of well-defined needs 1. How can we obtain large quantities of power cleanly, safely, and economically without using fossil fuels and without damaging the surface of the earth? 2. This gearshaft is giving trouble; there have been eight failures in the last six weeks. Do something about it

●起初,要满足的特定需求是很明确的。这里 是两个很明确的需求的例子。 ●1.怎样在不用化石燃料和不损坏地球表面的 情况下,可以清洁、安全、经济地得到大量 的动力。 ●2齿轮轴出现了问题,最近六周有八个故障。 在这方面做些工作

On the other hand, the particular need to be satisfied may be so nebulous and ill-defined that a considerable amount of thought and effort is necessary in order to state it clearly as a problem requiring a solution o Here are two examples 另一方面,欲满足的特定需求是模糊的和错 误定义的,当这些问题需要解决时,为清晰 地定义它需要付出大量的思考和努力。这里 有两个例子
