Decision Making
Decision making is an integral function of management. Decision making involves selecting or choosing a
particular course of action from among the various alternatives available in the decision making
situation.The process decision making involves 3 phases.1. Intelligence activity phase - identification of the problem.
2. Design activity phase - developing & analysing various course of actions.
3. Choice activity phase - choosing the best course of action.
Types of Problems & Decisions
Structured problems- straight forward, familiar & easy defined problems.
Unstructured problems- problems that are new or unusual for which information is ambiguous and
incomplete.
Programmed Decisions - handling customer complaints.
Non Programmed Decisions- mergers, acquisitions, takeovers, new facilities, new products, labor
contracts, legal issues.
Decision Making Conditions or Env
When making decisions, manage face three different conditions - certainty, risk and uncertainty.
A condition of certainty exists when the decision maker knows with reasonable certainty what alternatives
are, what conditions are associated with each alternative and outcome of each alternative. Under
conditions of certainty, accurate, measurable & reliable information on which to base decisions is
available.
When a manager lacks perfect information or whenever an information asymmetry exists, risk arises.Under a state of risk, the decision maker has incomplete information about available alternatives but has a
good idea of the probability of outcomes for each alternative. While making decisions, managers must
determine the probability associated with each alternative on the basis of the available information and his
experience.
Most significant decisions made in todays complex env are formulated under a state of uncertainty. The
decision maker is not aware of all available alternatives, the risks associated with each, the consequences
of each alternatives or their probabilities. In the face of such uncertainty, managers need to make certain
assumptions about the situation in order to provide a reasonable framework for decision making. Modern
approaches to decision making under uncertainty are risk analysis, decision trees, utility theory etc.
Decision Making Approach/Models
Classical Decision Theory
Classical model views the decision maker acting in a world of complete certainty. The rational modelof
decision making has its root in the economic theory maximizing profit or utility. According to rational
model, managers engage in a decision making process which is totally rational. They have all the relevant
information needed to take decisions. They are also aware of different possible alternatives, outcomes and

consequences and hence make rational decisions.
But it is very difficult for managers to be completely rational in their decision making, since decisions are
taken keeping the future in mind and the future is very uncertain. It is very difficult to determine all the
alternative course of action that might be followed to accomplish a goal.
Classical decision theory may not fit well in a chaotic world. It can be used towards the bottom of many
firms.
Behavioral Decision Theory
Behavioral decision theory recognizes that human beings operate with cognitive limitations and bounded
rationality. A behavioral decision maker faces a problem that is not clearly defined & he has only limited
knowledge of possible alternatives and their consequences. These limitations force him to choose a
satisfactory alternative.
Behavioral decision theory fit with a chaotic world of uncertain conditions and limited information. And thismodel encourages satisficing decision making. However, keep in mind that their decision making is also
likely influenced by the organizations culture, internal politics, power considerations, and by a phenomenon
called escalation of commitment, which is an increased commitment to a previous decision despite
evidence that it may have been wrong.
Garbage Can Model
A model of decision making that views problems, solutions, participants and choice situations as mixed
together in the garbage can of the organization. Garbage model of decision theory is more appropriate in
dynamic settings.
Incremental Model
Another approach to decision making is the incremental model. The incremental model states that the
managers put in the least possible effort - only enough to reduce the problem to a tolerance level.
Managers are more concerned about a short term solution. This model does not require managers to
process a great deal of information in order to take a decision.
Decision Makers Styles
Linear Thinking Style- Preference for using external data and facts and processing this information
through rational logical thinking to guide decisions and actions.
Nonlinear Thinking Style- Preference for internal source of information like feelings & intuition and
processing this information with internal insights, feelings and hunches to guide decisions and actions.
Decision Making Process
1. Identifying a problem- A problem is an obstacle that makes it difficult to achieve a desired goal or
purpose. Prior to identifying the problem, it is essential to first recognize that a problem exists.
Identification of a problem involves 3 stages - scanning, categorization & diagnosis.

2. Identifying the decision criteria.
3. Allocating weights to decision criteria - If the relevant criteria are not equally important, the
decision maker must weigh the items in order to give them the correct priority in the decision.
4. Developing alternatives - Brainstorming
5. Analyzing alternatives- Feasibility, quality, acceptability, cost & ethics
6. Selecting an alternative- Experience, Experimentation & Research & Analysis7. Implement the alternative.
8. Evaluating decision effectiveness.
Scanning involves monitoring the work env for changes that may indicate the emergence of a problem.
Heuristics
A heuristic is a mental shortcut that allows people to solve problems and make judgments quickly and
efficiently. These rule-of-thumb strategies shorten decision-making time and allow people to function
without constantly stopping to think about their next course of action. While heuristics are helpful in manysituations, they can also lead to biases.
While heuristics can speed up our problem and decision-making process, they can introduce errors. Just
because something has worked in the past does not mean that it will work again, and relying on an existing
heuristic can make it difficult to see alternative solutions or come up with new ideas.
Availability heuristic- tendency for the people to base their judgments on information that is
readily available to them rather than complete data..

Representativeness heuristic- tendency for people to assess the likelihood of an occurrence by
trying to match it with a pre existing category.
Anchoring and adjustment heuristic bases a decision on incremental adjustments to an initial
value determined by historical precedent or some reference point.
General judgment biases in decision making are Confirmation trap- The tendency to seek confirmation for what is already thought to be true and
to not search for disconfirming information.
Hindsight trap- The tendency to overestimate the degree to which an event that has already taken
place could have been predicted.
Creativity in Decision Making
Creativity in decision making involves the development of unique and novel responses to problems and
opportunities. Creativity is especially important in a dynamic environment full of nonroutine problems.
Stages in the creative thinking process.
1. Preparation.
2. Concentration.
3. Incubation.
4. Illumination
5. Verification.
Ethics in Decision Making
Ethics is the study of moral values or principles that guide our behaviour, and inform us whether actions
are right or wrong. Ethical principles help us do the right thing.
Ethical dilemma is a situation in which a person must decide whether or not to do something that, althoughpersonally or organizationally beneficial, may be considered unethical and perhaps illegal. Ethical dilemma
are often associated with
Risk & uncertainty
Nonroutine problem situations.
An individual can use four different criteria in making ethical choices.
Is my action legal?
Is it right?
Is it beneficial?
How would I feel if my family found out about this?
How would I feel if my decision were printed in the local newspaper?

Suggestions for integrating ethical decision making into the firm.
Develop a code of ethics and follow it.
Establish procedures for reporting violations.
Involve employees in identifying ethical issues.
Monitor ethical performance.
Reward ethical behavior. Publicize ethical efforts.
Implications of ethics for decision making.
Morality is involved in:
Choosing problems.
Deciding who should be involved in making decisions.
Estimating the impacts of decision alternatives.
Selecting an alternative for implementation.
Moral conduct does not arise from after-the-fact embarrassment.
Decision making realities Managers face complex choice processes.
Decision making information may not be available.
Bounded rationality and cognitive limitations affect the way people define problems, identify
alternatives, and choose preferred solutions.
Most decision making in organizations goes beyond step-by-step rational choice.
Most decision making in organizations falls somewhere between the highly rational and the highly
chaotic.
Decisions must be made under risk and uncertainty.
Decisions must be made to solve nonroutine problems.
Decisions must must be made under time pressures and information limitations. Decisions should be ethical.
Group Decision Making
In many organizations, decisions are often made by groups rather than by individuals. Group decision
making is practiced in many large and complex organizations. Many studies have shown that groups
makes better decisions than individuals, since more information is available in a group setting. Main
advantages of group decision making are

Greater pool of knowledge
Different perspective
Increased acceptance
Training ground.
The most common forms of group decision making are interacting group, delphi groups and nominal
groups.
Interactive groupsis a decision making group in which the members openly discuss, argue and agree on
the best alternative. In this form of group decision making, an existing groups like a standing committee or
a newly designated group such as an ad hoc committee or task force is entrusted with the task of taking a
decision. The discussion is open and interactive and group arrives at a decision after discussing the pros
and cons of various alternatives. An advantage of this method is that the interaction between people brings
forth many new ideas and improves understanding between the members of the group. However, a major
disadvantage of this form of group decision making is that political factors can influence it to a great
extent.
Some of the disadvantages of group decision making are
Social pressure
Domination by a vocal few.
Logrolling - pet project or vested interest is at stake.
Goal displacement - secondary considerations take preference.
Groupthink - compromise
Delphi Group
This is technique is similar to the nominal group technique, but differs from it in that the decision makers do
not actually meet at a common place. The various stages in delphi technique are A small group is formed comprising of individuals with reasonable expertise in the decision making
situation. However, they do not have face to face interaction with each other.
Each expert is sent a questionnaire consisting of questions relevant to the decision making
situation. The expert advice of each individual decision maker is sought.
The summarised result or feedback of the survey is then sent back to the experts seeking their
response to the results.
The process is repeated several times until a consensus among the experts is obtained.
This method has the benefit of overcoming personal biases of decision makers. Research shows that org
implementing this technique have been successful in generating innovative ideas to the problem situation.
This method is not used for everyday routine decisions because it is time consuming and expensive.
Nominal Groups- In a nominal group technique, the group of members are actually brought together, but
they dont interact as freely as the members of interactive group. This technique is generally used when
creative or innovative ideas are required.

Brainstorming - A idea generation process that specifically encourages any and all alternatives while
withholding any criticism of those alternatives.
Factors Affecting Decision Making
Types of Problems- structured / unstructured
Decision Making Env- certainty / risk / uncertainty
Decision Makers Style - Linear / Nonlinear
Information Inputs
It is very important to have adequate and accurate information about the situation for decision making,
otherwise the quality of the decision will suffer. It must be recognized, however, that on individual has
certain mental constraints, which limit the amount of information that he can adequately handle. Less
information is as dangerous as too much information. Some highly authoritative individuals do make
decisions on the basis of comparatively less information when compared to more conservative decision
makers.
Prejudice & Bias
Prejudice and bias is introduced in our decisions by our perceptual processes and may cause us to make
ineffective decisions. First, perception is highly selective, which means that we only accept what we want
to accept and hence only such type of information filters down to our senses.
Second, perception is highly subjective, meaning that information gets distorted in order to be consistent
with our pre-established beliefs, attitudes and values.
Cognitive Constraints
A human brain, which is the source of thinking, creativity and decision making, is limited in capacity in a
number of ways. For example, except for some unique circumstances, our memory is short term, having
the capacity of only a few ideas, words and symbols. Also, we cannot perform more than a limited number
of calculations in our heads and it is tough to compare all the possible alternatives and make a choice.
Finally, psychologically, we are always uncomfortable with making decisions. We are never really sure if
our choice of the alternative was correct and optimal until the impact of the implication of the decision has
been felt. This makes us feel insecure.
Social & Cultural Influences
Social norm is the standard and accepted way of making judgements. Cultural upbringing and various
cultural dimensions have a profound impact on the decision-making style of an individual. For example, in
8/21/2019 03_1DecisionMaking

the Japanese organizational system, a decision maker arrives at a decision in consensus with others. This
style is culturally oriented and makes implementation of the decision much easier since everybody
participates in the decision-making process. In America, on the contrary, the decision-making style is
generally individualistic with the help of decision models and quantitative techniques.
Escalation of Commitment
An increased commitment to a previous decision despite negative information. Individuals escalate
commitment to a failing course of action when they view themselves as responsible for the failure. That is,
they throw good money after bad to demonstrate that their initial decision was not wrong and to avoid
having to admit they made a mistake. Many organizations have suffered large losses because a manager
was determined to prove his or her original decision was right by continuing to commit resources to what
was a lost cause from the beginning.
