Information System• An information system (IS) collects, processes, stores,

analyzes, and disseminates information for a specific purpose. Like any other system, an information system includes inputs (data, instructions) and outputs (reports, calculations). It processes the inputs by using technology such as PCs and produces outputs that are sent to users or to other systems via electronic networks and a feedback mechanism that controls the operation.

MANAGERIAL ISSUES• Recognizing opportunities for using IT and Web-based systems. • Who will build, operate, and maintain the information systems. This is

a critical issue because management wants to minimize the cost of IT while maximizing its benefits. Some alternatives are to outsource portions, or even all, of the IT activities, and to divide the remaining work between the IS department and the end users.

• How much IT? This is a critical issue related to IT planning. IT does not come free, but not having it may be much costlier.

• How important is IT? In some cases, IT is the only approach that can help organizations. As time passes, the comparative advantage of IT increases.

• Is the situation going to change? Yes, the pressures will be stronger as time passes. Therefore, the IT role will be even more important.

• Globalization. Global competition will have an impact on many companies. However, globalization opens many opportunities, ranging from selling and buying products and services online in foreign markets, to conducting joint ventures or investing in them. IT supports communications, collaboration, and discovery of information regarding all the above.

MANAGERIAL ISSUES Continued

• Ethics and social issues. The implementation of IT involves many ethical and social issues that are constantly changing due to new developments in technologies and environments. These topics should be examined any time an IT project is undertaken.

• Transforming the organization to the digital economy. The transformation can be done on several fronts. Management should study the opportunities, consider alternatives and prioritize them.
