Слайд 1The
Manager as a
Decision Maker
Слайд 2Managerial Decision Making
Decision making: the process by which managers respond
to opportunities and threats by analyzing options, and making decisions
about goals and courses of action.
Decisions in response to opportunities: managers respond to ways to improve organizational performance.
Decisions in response to threats: occurs when managers are impacted by adverse events to the organization.
Слайд 3Types of Decision Making
Programmed Decisions: routine, almost automatic process.
Managers have
made decision many times before.
There are rules or guidelines to
follow.
Example: Deciding to reorder office supplies.
Non-programmed Decisions: unusual situations that have not been often addressed.
No rules to follow since the decision is new.
These decisions are made based on information, and a manger’s intuition, and judgment.
Example: Should the firm invest in a new technology?
Слайд 4The Classical Model
Classical model of decision making: a prescriptive model
that tells how the decision should be made.
Assumes managers have
access to all the information needed to reach a decision.
Managers can then make the optimum decision by easily ranking their own preferences among alternatives.
Unfortunately, mangers often do not have all (or even most) required information.
Слайд 5The Classical Model

& consequences
Rank each alternative
from low
to high

the organization
Figure 6.1
Слайд 6The Administrative Model
Administrative Model of decision making: Challenged the classical
assumptions that managers have and process all the information.
As a
result, decision making is risky.
Bounded rationality: There is a large number of alternatives and information is vast so that managers cannot consider it all.
Decisions are limited by people’s cognitive abilities.
Incomplete information: most managers do not see all alternatives and decide based on incomplete information.

Figure 6.2
Слайд 8Incomplete Information Factors
Incomplete information exists due to many issues:
Risk: managers
know a given outcome can fail or succeed and probabilities
can be assigned.
Uncertainty: probabilities cannot be given for outcomes and the future is unknown.
Many decision outcomes are not known such as a new product introduction.
Ambiguous information: information whose meaning is not clear.
Information can be interpreted in different ways.
Слайд 9Incomplete Information Factors
Time constraints and Information costs: Managers do not
have the time or money to search for all alternatives.
This
leads the manager to again decide based on incomplete information.
Satisficing: Managers explore a limited number of options and choose an acceptable decision rather than the optimum decision.
This is the response of managers when dealing with incomplete information.
Managers assume that the limited options they examine represent all options.
Слайд 10Decision Making Steps
Recognize need for
a decision
Frame the problem
Generate &
assess alternatives
Choose among alternatives
Implement chosen
alternative
Learn from feedback
Figure 6.4
Слайд 11Decision Making Steps
1. Recognize need for a decision: Managers must
first realize that a decision must be made.
Sparked by an
event such as environment changes.
2. Generate alternatives: managers must develop feasible alternative courses of action.
If good alternatives are missed, the resulting decision is poor.
It is hard to develop creative alternatives, so managers need to look for new ideas.
3. Evaluate alternatives: what are the advantages and disadvantages of each alternative?
Managers should specify criteria, then evaluate.
Слайд 12Decision Making Steps
4. Choose among alternatives: managers rank alternatives and
decide.
When ranking, all information needs to be considered.
5. Implement choose
alternative: managers must now carry out the alternative.
Often a decision is made and not implemented.
6. Learn from feedback: managers should consider what went right and wrong with the decision and learn for the future.
Without feedback, managers never learn from experience and make the same mistake over.
Слайд 13Evaluating Alternatives
Legal?
Ethical
Economical?
Practical?
Is the possible course of action:
Figure 6.5
Слайд 14Evaluating Alternatives
Is it legal? Managers must first be sure that
an alternative is legal both in this country and abroad
for exports.
Is it ethical? The alternative must be ethical and not hurt stakeholders unnecessarily.
Is it economically feasible? Can our organization’s performance goals sustain this alternative?
Is it practical? Does the management have the capabilities and resources to do it?
Слайд 15Cognitive Biases
Suggests decision makers use heuristics to deal with bounded
rationality.
A heuristic is a rule of thumb to deal with
complex situations.
If the heuristic is wrong, however, then poor decisions result from its use.
Systematic errors can result from use of an incorrect heuristic.
These errors will appear over and over since the rule used to make decision is flawed.
Слайд 16Types of Cognitive Biases
Prior Hypothesis
Representativeness
Illusion of Control
Escalating Commitment
Cognitive
Biases
Figure 6.6
Слайд 17Types of Cognitive Biases
Prior hypothesis bias: manager allows strong prior
beliefs about a relationship between variables and makes decisions based
on these beliefs even when evidence shows they are wrong.
Representativeness: decision maker incorrectly generalizes a decision from a small sample or one incident.
Illusion of control: manager over-estimates their ability to control events.
Escalating commitment: manager has already committed considerable resource to project and then commits more even after feedback indicates problems.
Слайд 18Group Decision Making
Many decisions are made in a group setting.
Groups
tend to reduce cognitive biases and can call on combined
skills, and abilities.
There are some disadvantages with groups:
Group think: biased decision making resulting from group members striving for agreement.
Usually occurs when group members rally around a central manger’s idea (CEO), and become blindly committed without considering alternatives.
The group tends to convince each member that the idea must go forward.
Слайд 19Improved Group Decision Making
Devil’s Advocacy: one member of the group
acts as the devil’s advocate and critiques the way the
group identified alternatives.
Points out problems with the alternative selection.
Dialectical inquiry: two different groups are assigned to the problem and each group evaluates the other group’s alternatives.
Top managers then hear each group present their alternatives and each group can critique the other.
Promote diversity: by increasing the diversity in a group, a wider set of alternatives may be considered.

Слайд 21Organizational Learning & Creativity
Organizational Learning: Managers seek to improve member’s
ability to understand the organization and environment so as to
raise effectiveness.
The learning organization: managers try to improve the people’s ability to behave creatively to maximize organizational learning .
Creativity: is the ability of the decision maker to discover novel ideas leading to a feasible course of action.
A creative management staff and employees are the key to the learning organization.

Слайд 23Creating a Learning Organization
Senge suggests top managers follow several
steps to build in learning:
Personal Mastery: managers empower employees and
allow them to create and explore.
Mental Models: challenge employees to find new, better methods to perform a task.
Team Learning: is more important than individual learning since most decisions are made in groups.
Build a Shared Vision: a people share a common mental model of the firm to evaluate opportunities.
Systems Thinking: know that actions in one area of the firm impacts all others.
Слайд 24Individual Creativity
Organizations can build an environment supportive of creativity.
Many of
these issues are the same as for the learning organization.
Managers
must provide employees with the ability to take risks.
If people take risks, they will occasionally fail.
Thus, to build creativity, periodic failures must be rewarded.
This idea is hard to accept for some managers.
Слайд 25Building Group Creativity
Brainstorming: managers meet face-to-face to generate and debate
many alternatives.
Group members are not allowed to evaluate alternatives
until all alternatives are listed.
Be creative and radical in stating alternatives.
When all are listed, then the pros and cons of each are discussed and a short list created.
Production blocking is a potential problem with brainstorming.
Members cannot absorb all information being presented during the session and can forget their own alternatives.
Слайд 26Building Group Creativity
Nominal Group Technique: Provides a more structured way
to generate alternatives in writing.
Avoids the production blocking problem.
Similar
to brainstorming except that each member is given time to first write down all alternatives he or she would suggest.
Alternatives are then read aloud without discussion until all have been listed.
Then discussion occurs and alternatives are ranked.
Слайд 27Building Group Creativity
Delphi Technique: provides for a written format without
having all managers meet face-to-face.
Problem is distributed in written form
to managers who then generate written alternatives.
Responses are received and summarized by top managers.
These results are sent back to participants for feedback, and ranking.
The process continues until consensus is reached.
Delphi allows distant managers to participate.
