Decision Making and Problem Solving
Succeeding with Technology 4th ed > Information, Decision Support… >
Decision Making & Problem Solving Process
Potential Problems and opportunities are identified
and defined
Alternative solutions to the problem are developed
Select a course of action
Solution put into effect
Evaluate the implementation
Succeeding with Technology 4th ed > Information, Decision Support… >
Decision Types
Programmed decisionsStructured situations with well
defined relationshipsQuantifiable
Non-programmed decisionsIll-structured situations with
vague or changing relationships between variables
Not easily quantifiable in advance
Succeeding with Technology 4th ed > Information, Decision Support… >
Optimization and Heuristic
Optimization Model: find the best solution, helping individuals or organizations meet goals.
Heuristics: commonly accepted guidelines or procedures that usually find a good solution, but not necessarily the optimal solution

Management Information Systems (MIS) MIS ~ used to support
programmed decisions made in response to structured problems.
Primary purpose is to help individuals and organizations achieve goals by providing reports and information used to make better decisions.

Reports
Scheduled Reports are produced periodically on a schedule; daily, weekly, monthly, quarterly, annually, etc.
Demand Reports are developed to get certain information at a person’s request.
Exception Reports are automatically produced when a situation is unusual or requires action.

Characteristics
Handles a range of data from small to large.
Obtains and processes data from different sources.
Provides report and presentation flexibility

Succeeding with Technology 4th ed > Information, Decision Support… >
Characteristics ~ What If?
What-if analysis is the process of making hypothetical changes to problem data and observing the impact on the results.
Succeeding with Technology 4th ed > Information, Decision Support… >
Goal-seeking
Goal-seeking analysis is the process of determining what problem data is required for a given result.
What must be done in order to safely withdraw troops within a year?

Group Decision Support Systems (GDSS)
A GDSS or computerized collaborative work system is designed to provide effective support in group decision-making settings.
A GDSS IS FLEXIBLE, SUPPORTS ANONYMOUS INPUT, AND REDUCES NEGATIVE GROUP DYNAMICS
