我个人的观点是，对需求进行编号，并力求简洁，这样繁忙的开发人员就可以方便地跟踪它们。

My personal opinion is that requirements should be numbered, brief, and to the point so busy developers can easily keep track of them.

如果你注册——有30,000个科学家已经这样做了——你会首先被分配一个唯一编号(Cals的号码a - 1262 - 2007，意思是在2007年注册的第1262个人)。

If you sign up — which some 30, 000 scientists have done — you are first assigned a unique number. (Cals's number, A-1262-2007, means he was the 1262nd person to sign up in 2007.)
