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?
(A) Postal workers are representative of service workers in general.
(B) The delivery of letters is the primary activity of the postal service.
(C) Productivity should be ascribed to categories of workers, not to individuals.
(D) The quality of services rendered can appropriately be ignored in computing productivity.
(E) The number of letters delivered is relevant to measuring the productivity of postal workers.
这个问题是问什么？？ 不太理解
D
衡量服务业工人的生产效率比较复杂。仅以数量衡量邮政工人的生产效率可以么？后面的丢信和延迟等代表质量。问上述分析基于什么？
很明显就是在衡量服务业工人的生产效率是，不可以忽略质量。
