The Importance of Information Systems Management, 8e (McNurlin/Sprague/Bui)
Chapter 12 Supporting Decision Making
1) Decision support systems are designed to address well-structured problems.
2) Decision support systems are relatively new technology, having first emerged in 1995.
3) Decision support systems do not require end-user interfaces as they solve problems
automatically.
4) Decision support systems usually utilize detail transaction level data.
5) Quick-hit DSSs can only be created using a DSS generator.
6) Data mining uncovers unknown patterns and correlations in data.
7) Data mining requires significant amounts of detailed data.
8) An EIS can scan the environment for the latest competitor information.
9) Expert systems utilize artificial intelligence to solve a problem the way a human expert
would.
10) Comparing a current problem to thousands of prior problems is referred to as case-based
reasoning.
11) Neural networks are a type of expert system.

12) Simulation-based modeling for studying emergent behavior is referred to as transitional-
based modeling.
13) An enterprise nervous system uses a publish-an- subscribe approach.
14) Reacting quickly to new information to gain a competitive edge is referred to as straight-
through processing.
15) An RFID can tell you what it is attached to and where it is located.
16) Most computer systems have some built-in features that help their users make decisions.
17) In the mainframe era, the earliest commercial uses of computers aimed to automate
decisions such as analyzing sales, updating accounts payable, and calculating payroll.
18) Decision making in organizations has often been seen as a rational and coherent process.
19)
It really does not matter where decision making starts or stops because all the activities are
part of the overall process of solving the problem.
20)
Using artificial intelligence, the manager can build a network of arguments to represent a
chain of business reasoning.
