DECISION MAKING
and
PROBLEM SOLVING
Discussant: Christopher G. Aguilar
Take a look at these illustrations. What do you see?
The square on the right is obviously larger in area than the one on the left, isn’t it? How about the circles? Which looks larger in circumference and diameter? The oneon the right? Not so! If you measure them, you’ll see that they are identical in size.
ISSUE: Identify the best location for new school site.If after evaluating each of the primary locations only one viable choice remains, then there is really no decision left to make. But if three locations each meet the basic requirements and have different relative strengths, the president will then have to make a decision from among the options.
** most of our interest relates to decision making**
What is DECISION MAKING?
Is the process of choosing one alternative from among several.
What is PROBLEM SOLVING?
Is finding the answer to a question.
Basic Elements of DECISION MAKING . Goal
. Courses of action outcomes
. Information (available) Alternatives
.. each has an outcome likely to occur
.. Value of each outcome relative to goal
. Decision maker chooses alternative on the basis of his her evaluation of the information

Elements of Decision Making
Decisions made in organizations can be classified according to:
FREQUENCY - how often a particular decision situation recurs
INFORMATION – are conditions describe how much information is available about the likelihood of various outcomes
Types of DECISIONS on the frequency of recurrence
1. Programmed decision – recurs often enough for decision rules to be developed.
- usually are highly structured :
a. goals are clear and well known;
b. decision-making procedure is already established; and
c. sources and channels of information are clearly defined
Types of DECISIONS on the frequency of recurrence
2. Nonprogrammed decision – when a problem or decision situation has not been encountered before, however, a decision maker cannot rely on previously established decision rules
- requires problem solving (a special form of decision making in which the issue is unique – it requires developing and evaluating alternatives without the aid of a decision rule.
** one key element of nonprogrammed decisions is that they require good judgment on the part of leaders and decision makers.
Characteristics Programmed

Nonprogrammed
Decisions
Type of Decision Well structured Poorly structured
Frequency Repetitive and routine
New and unusual
Goals Clear, specific Vogue
Information Readily available Not available, unclear channels
Consequences Minor Major
Organizational level Lower levels Upper levels
Time for solution Short Relatively long
Basis for solution Decision rules, set procedures
Judgment and creativity
Characteristics of Programmed and Nonprogrammed Decisions
Information required for DECISION MAKING
1. Complete certainty - when all alternative outcomes are known
2. Complete uncertainty - when all alternative outcomes are unknown
3. Condition of Risk (points between the two extremes)
- the decision maker has some information about the possible outcomes and may be able to estimate the probability of their occurrence
- the outcome of a given action is not known but has enough information to estimate the probabilities of various outcomes

Approaches to DECISION MAKING
Rational Approach - assumes that managers follow a systematic , step-by-step process from goals to implementation, measurement, and control. It further assumes the organization is dedicated to making logical choices and doing what makes the most sense economically and managed by decision makers who are entirely objective and have complete information.
* actual decision making often is not wholly rational process
Steps in Rational Approach
1. State the Situational Goal
the rational decision-making process begins with the statement of a situational goal-that is a goal for a particular situation.
2. Identify the Problem
the purpose of problem identification is to gather information that bears on the goal. If there is discrepancy between the goal and the actual state, action maybe stated.
3. Determining Decision Type
decision makers must determine if the problem represents a programmed or a nonprogrammed decision.
4. Generate Alternatives
decision makers may rely on education and experience as well as knowledge of the situation to generate alternatives
5. Evaluate Alternatives
decision maker must examine each alternative for evidence that it will reduce the discrepancy between the desired state and the actual state.
6. Choose Alternative
choosing consists of selecting the alternative with the highest possible payoff, based on the benefits, costs, risks, and uncertainties of all alternatives.
7. Implement the Plan
implementation requires the proper use of resources and good managerial skills;
the success depends on the leadership, the reward structure, the communications system, and group dynamics.
8. Control: Measure and Adjust
the outcomes of the decision are measured and compared with the desired goal
The BEHAVIORAL APPROACH
- acknowledges the role and importance of human behavior in the decision-making process
- decision makers operate with bounded rationality rather with the perfect rationality assumed by the rational approach
BEHAVIORAL APPRAOCH is characterized by:
1. the use of procedures and rules of thumb – initially reduced uncertainty in
decision making
2. suboptimizing - is accepting less than the possible outcome - - - frequently, it is not feasible to make the ideal decision in a real-world situation given organizational constraints
3. satisficing - is examining alternatives only until a solution that meets minimal requirements is found and then ceasing to look for a better one
PERSONAL APPROACH
- Janis-Mann concept called the conflict model (Irving Janis and Leon Mann)
- based on research in social psychology and individual decision processes
Characteristics of Personal Approach
1. it deals with important life decisions
* marriage, schooling, career, and
major organizational decisions
Characteristics of Personal Approach
2. It recognizes that procrastination and rationalizations are mechanisms by which people avoid making difficult decisions and coping with the associated stress
3. It explicitly acknowledges that some decisions probably will be wrong and that the fear of making an unsound decision can be a deterrent to making any decision at all
Characteristics of Personal Approach
4. It provides for self-reaction – comparisons of alternatives with internalized moral standards
5. It recognizes that at times the decision maker is ambivalent about alternative courses of action
