There is an awful lot of work that can be done on a system before all the requirements have been completed, since not all requirements are inter-related or of equal importance.

既然不是所有的需求都是内在关联的或是同等重要的，在所有的需求都被完成之前同样存在着极大量可以在系统上被完成的工作。

Or, even worse, you start early and get a few minor things done (not a bad idea by itself), but then feel satisfied that you've made progress and wait too long to get the hard parts completed.

或者更糟的是，你开始得倒挺早，处理了些细枝末节的事(这本身倒还不错)，但后来感觉自己做出了点成效，便心满意足，等过了太久才去处理棘手的事项。
