Before the widespread use of computers, managers could not make full use of large amounts

Before the widespread use of puters, managers could not make full use of large amounts of valuable information about a pany’s activities. The information either reached managers too late or was too expensive to be used. Today, managers are facing a wide range of data processing and information instruments. In place of a few financial controls, managers can draw on puter-based information systems to control activities in every area of their pany. On any kinds at performance measures, the information provided by these systems helps managers pare standards with actual results, find out problems, and take corrective action before it is too late to make changes.
The introduction of puterized information systems has sharply changed management control in many panies. Even a neighborhood shopkeeper may now use puters to control sales and other activities. In large panies, electronic data processing systems monitor entire projects and sets of operations.
Now, there are about 24 million microputers in use in the United States, one for every 10 citizens. It is estimated 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 puter-based information they are receiving is accurate, they need to understand how puters work. However, in most cases they do not need to learn how to program puters. Rather, managers should understand how puterized information systems work; how they are developed; their limitations and costs; and the manner in which information system 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 puters to business graduates than they were in teaching business subjects to puter science graduates.
