Why study information systems and information technology? That’s the same as asking why anyone should study accounting, finance, operations management, marketing, human resource management, or any other major business function. Information systems and technologies (including e-business and e-commerce technologies and applications) have become a vital component of successful businesses and organizations. They thus constitute an essential field of study in business administration and management. That’s why most business majors must take a course in information systems. Since you probably intend to be a manager, entrepreneur, or business professional, it is just as important to have a basic understanding of information systems as it is to understand any other functional area in business.

There are three fundamental reasons for all business applications of information technology. They are found in the three vital roles that information systems can perform for a business enterprise.

• Support of its business processes and operations.
• Support of decision making by its employees and managers.
• Support of its strategies for competitive advantage.
