Correctly measuring the productivity of service workers is complex. Consider, for example, postal workers: they are often said to be more productive if more letters are delivered per postal worker. But is this really true? What if more letters are lost or delayed per worker at the same time that more are delivered?
The objection implied above to the productivity measure described is based on doubts about the truth of which of the following statements?
Postal workers are representative of service workers in general.
The delivery of letters is the primary activity of the postal service.
Productivity should be ascribed to categories of workers, not to individuals.
The quality of services rendered can appropriately be ignored in computing productivity.
The number of letters delivered is relevant to measuring the productivity of postal workers.
AB是阐述，在这没有任何效果
E是支持了这个衡量方式
C是质疑整个定义，而不是这个举例了
D 肯定了工作量，质疑了工作质量
