The function of the office is to perform administrative work. First, it must provide the necessary communications with customers, banks, government departments, and other outside organizations. Second, it must service the information requirements within the company itself. In order to meet these needs efficiently, the Office Manager must employ the most appropriate business methods, systems and equipment. In an efficient administrative structure, clerical operations are organized so that they add to the profitability of the business. However, in many countries the number of clerical staff has increased while the total number of workers employed in production has fallen. In Britain, for example, the total workforce in the years 1919-1976 went up by 25%, while the number of people who were employed in clerical work increased by 150%. For a country such as Britain, which depends on a manufacturing base, that can mean inefficiency. To ensure that office services run smoothly, there must be the means to check, sort, copy and file correspondence and other paperwork. Today there is a growing range of machines that can be used to do such jobs. The size and resources of a company will determine how mechanized or computerized its office systems are. The office must give maximum service at minimum cost. A balance must be kept between production, marketing, and administration. As a company develops and grows, the contribution of administration will vary in kind and in value. The most important objective in modern offices is the processing of data in order to provide a means of business control, but in many companies there are weaknesses in the ability to manage communications efficiently. For example, some data are often used only by individual managers, and different departments in the same company may use different data processing systems. In order to contribute to business efficiency, however, data processing must be a centralized service, The system which is required is one that looks at the total needs of a business and therefore assists management in making appropriate decisions quickly.
A．the business methods and systemsB．the correspondence and other paperworkC．the data and data processing systemsD．the size and resources of a company
