The following is a memorandum from the director of personnel to the president of Get－Away Airlines.
　　"Since our mechanics are responsible for inspecting and maintaining our aircraft， Get－Away Airlines should pay to send them to the Quality－Care Seminar， a two－week seminar on proper maintenance procedures. I recommend this seminar because it is likely to be a wise investment， given that the automobile racing industry recently reported that the performance of its maintenance crews improved markedly after their crews had attended the seminar. These maintenance crews perform many of the same functions as do our mechanics， including refueling and repairing engines. The money we spend on sending our staff to the seminar will inevitably lead to improved maintenance and thus to MSEater customer satisfaction along with MSEater profits for our airline."
