Chapter 2 Information Systems in the Enterprise
As we discussed in Chapter 1, the "digital firm" means more than just plunking or putting down computers that have all the latest bells and whistles (technology) on every employee’s desk. The digital firm must connect each functional area and each management level to one another. Data input to the system in manufacturing must be made available to sales, accounting, and shipping. Managers in the human resources department must have access to appropriate information regardless of its origin. Information integration is the key to the digital firm. As we go through this chapter, we'll look at the types of information systems organizations use at each management level. To help distinguish between the type of function each one is designed to accomplish and to fit them all together, we're going to look at them in the context of manufacturing candy bars. Yes, candy bars. Everyone likes them and everyone has eaten one, so they will be easy to relate to. We'll call the company WorldWide Candy and we'll give the candy bar the timely name of "Cybernuts." 2.1 Major Types of Systems in Organizations
You'll see at the end of this discussion the integral role each type of system plays — from determining which kind of candy bar to make (strategic level systems); to how many people the company will need to make the candy bar (management level systems); to tracking customer orders (operational level systems). Within these three levels we'll discuss the four major types of systems typically used to make an organization successful. [pic]
Transaction Processing Systems
The operational level of the organization includes the various units listed in Figure 2.2 and is responsible for daily operations. The information systems used in this level of the organization are transaction processing systems (TPS), so-called because they record the daily routine transactions that take place in everyday operations. TPS combine data in various ways to fulfill the hundreds of information needs a company requires to be successful. The data are very detailed at this level. For instance, a TPS will record how many pounds of sugar are used in making our Cybernuts candy bar. It also records the time it takes from beginning to end to make the candy bar. And it can record the number of people working on the assembly line when our candy bar is made and what functions they perform. People using transaction processing systems usually need information to help them answer routine questions such as: "How many Cybernuts candy bars did we produce yesterday?" or...
