单选题
Before the widespread use of computers, managers could not
make full use of large amounts of valuable information about a company's
activities. The information either reached managers too late or was too
expensive to be used. Today, mangers are facing a wide range of data processing
and information instruments. In place of a few financial controls, managers can
draw on computer-based information systems to control activities in every area
of their company. On any kind of performance measures, the information provided
by these systems helps mangers compare standards with actual results, find out
problems, and take action before it is too late to make changes.
The introduction of computerized information system has sharply changed
management control in many companies. Even a neighborhood shopkeeper many now
use computers to control sales, billing, and other activities. In large
companies, electronic data processing systems monitor entire projects and sets
of operations. Now, there are about 24 million microcomputers
in use in the United States, one for every 10 citizens. It is said that by 1996,
61 percent of American managers will be using some sort of electronic
workstation. In order for managers to be sure that the computer-based
information they are receiving is accurate, they need to learn how computers
work. However, in most cases they do not need to learn how to program computers.
Rather, mangers should understand how computerized information systems work, how
they are developed, their limitations and costs, and the manner in which
information systems may be used. Such an understanding is not difficult to
achieve. One research found that business firms were more successful in teaching
basic information about computers to business graduates than they were in
teaching business subjects to computers science graduates.
