Переведите, пожалуйста, текст!
Big companies have many managers who head departments. They are all responsible to the managing director. The board of directors appoints managing director to be in charge of the day-to-day running of the company. Among various departmental managers the following can be mentioned:
a) personnel manager, who heads the personnel department in a company that deals with employing and training people;
b) sales and marketing manager, who deals with the business of advertising and selling goods or services and thus he is in charge of promoting the company product;
c) management accountant.
Let us consider the role of a management accountant for a company.
Top management very often depends on the management accountant for information necessary for making decisions. To evaluate decision alternatives the accountant uses special analysis and reporting techniques. Decisions about long-capital expenditures are the most complex. However, day-to-day operating decisions call for accurate evaluation too. So a major task of managers is to set plans for the business on the information presented by the management accountant. Having set plans for business, managers must monitor progress and take any corrective actions. To do their work properly management accountants should be highly qualified and they need to keep up with the latest developments in the uses of computers and in computer system designs.
