It is a good thing to occasionally lift our sights from the job in hand and focus our attention on the broader purpose of our actions For example, if we ask ourselves what the purpose of maintenance is, we might answer that it is to keep the equipment we are using in a condition which does not fall below a certain standard In the narrow sense, a definition of some such sort would pass, but surely, if we accept it as a complete answer to our question, we are really saying that maintenance is an end unto itself This, of course, is quite ridiculous because maintenance is not just done for the fun of it, rather its purpose is to carry out certain work, m close association with quite different types of work, so that the integrated effort enables the equipment in use to satisfactorily perform the task in handm the case of a commercial airline, this would be to earn money by giving the best possible public service Some such reply I think would be a more complete answer to our question
