Chapter 5 Business Intelligence and Knowledge Management Systems PowerPoint Presentation by Charlie Cook Copyright © 2004 South-Western. All rights reserved. Learning Objectives • To recognize how information is used for different types of decisions at various levels in the organization • To become familiar with the support that management receives from decision aids such as Business Intelligence systems, OLAP, groupware, expert systems, and intelligent agents • To understand the importance and challenges of formally managing organizational knowledge, and to recognize the technologies that enable successful knowledge management Copyright © 2004 South-Western. All rights reserved. 5–2 Management Decision Making • Classic decision making model (Simon) Intelligence: searching the environment for conditions calling for a decision. Design: inventing, developing, and analyzing possible courses of action. Choice: selecting a course of action. • Types of decisions Structured decisions Unstructured decisions Copyright © 2004 South-Western.

Such feedback, of course, is an integral part of decision making and should improve the intelligence, design, and choice that occur as part of an iterative process.

Copyright © 2004 South-Western. All rights reserved. • Inference engine Executes line of reasoning based on facts and rules. • User interface Provides for user input to system and displays output. Contains explanation facility to let user ask why and how. 5–11 Expert Systems Conditions favor the use of expert systems when: Decisions are extremely complex. Consistency of decision making is desirable. The decision must optimized (minimized for time and maximized for quality). An expert decision maker can be computer-modeled.

Mimic the human brain’s ability to recognize patterns, predict outcomes with incomplete information. Derive knowledge from data; must be “trained”. • Four types of neural network output: Prediction Classification Data Filtering Optimization Copyright © 2004 South-Western.

Failure to record knowledge of problems solved in the past. Copyright © 2004 South-Western.
