Before we begin our discussion of IS tools for a start-up organization, it is important to note that it may not be necessary to use a computer-based information system when you first go into business. You may be able to satisfy your information processing and record-keeping needs with manual systems. However, as the price of computers drop and your business expands, you may find it wise, as many small business owners do, to invest in computer-based information systems. Many people use Information Systems and Information Technology as if they meant the same thing. They are different, and it is important for you to understand the difference between them. As illustrated in Figure 10.1, an Information System is comprised of two sub-systems, a Social sub-system and a Technology sub-system.
The discussion of the four components of information systems as well as Figure 10.1 above has been extracted from another book in the Global Text library (Information Systems 2008).
