Chapter 10 Information and Decision Support Systems questions with accurate answers

Chapter 10 Information and Decision
Support Systems

Information System - answersAssist with problem solving, helping people make better
decisions and meeting corporate goals.
-(make more informed decisions which can result in an increase in revenue, reduce
costs, and new opportunities

Decision Making - answersStrategic planning and overall goals of the organization set
the course for decision making

DECISION MAKING PHASE HAS 3 STAGES
1) Intelligence stage: identify and define potential problems or opportunities
2) Design stage: develop alternatives solutions to the problem and evaluate their
feasibility
3) Choice stage: select a course of action

How decision making relates to problem solving - answersDECISION MAKING:
-Intelligence
-Design
-Choice

PROBLEM SOLVING (includes and goes beyond decision making w/ implementation
and monitoring)
-Intelligence
-Design
-Choice
-Implementation
-Monitoring

DECISON MAKING (~+problem solving)
1) Intelligence stage: identify and define potential problems or opportunities
2) Design stage: develop alternatives solutions to the problem and evaluate their
feasibility
3) Choice stage: select a course of action

IMPLEMENTATION STAGE:
A stage of problem solving in which a solution is put into effect

MONITORING STAGE:

, The FINAL stage of the problem solving process in which decision makers EVALUATE
THE IMPLEMENTATION

Structured, Unstructured and SemiStructured Decisions - answersSTRUCTURED
DECISIONS:
The variable that COMPRISE the decision are known and CAN be measured
quantitatively

UNSTRUCTURED DECISIONS:
The variable that AFFECTS the decision CAN NOT be measured quantitatively

SEMISTRUCTURED DECISIONS:
SOME of the variables CAN be measured quantitatively

3 Approaches to problem solving : Optimization, Satisficing, Heuristics -
answersOptimization model finds the best solution (the one that will best help the
organization meet its goals)

Satisficing model finds a good but not best solution

Heuristics "rules of thumb"
-commonly accepted guidelines or procedures that usually find a good solution

Benefits of Information and Decision Support Systems
(positive and negative impact) - answersPositive Impact: PERFORMANCE (DQ,PC,SD)
-Decision quality
-Problem Complexity
-Speedier decisions

Negative Impact: COST (HSDNnIPP)
-Hardware
-Software
-Database
-Network and Internet
-Personnel
-Procedures

Management Information Systems (MIS) - answersMIS:
-An integrated collection of people, procedures, databases and devices
-provides managers and decision makers with information to help achieve
organizations goals
-gives organization a competitive advantage

PURPOSE OF MIS:
