Decision Making




• ― the process of responding to a problem by searching
  and selecting a solution or course of action‖.

• There are basically two kinds of decision that are called
  upon to make:


  Programmed and non-programmed
                                                        Page 2
Types of Problems and Decisions
• Structured problems
 * Involve clear goals.
 *Are familiar (have occurred
   before)
 *Are easily and completely
  defined- information about the
   problem is available and complete.

• Programmed decision
 *A repetitive decision the can be handled by a
 routine approach.

                                             Page 3
• Unstructured problems
 * Problems that are new or unusual and for which
 information is ambiguous or incomplete.
 * Problems that will require custom-made
 solutions.


• Non-programmed decisions
 * Decision that are unique and non-recurring.
 * Decision that generate unique responses.



                                                 Page 4
Vitals of Decision making process
• Policy
• a general guideline for making a decision about a
  problem.
• Procedure
  * A series of interrelated steps that decision maker
  can use to respond ( applying a policy) to a problem.
• Rule
  * an explicit statement that limits what can or cannot
  be done.

Decision Making Process

•   Identifying Problem
•   Identifying Decision Criteria
•   Allocating Weights to the Criteria
•   Developing Alternatives
•   Analyzing Alternatives
•   Select Alternatives.
•   Implement Alternatives.
•   Evaluating decision’s effectiveness.


                                           Page 7
Step 1: Identifying the Problem

* A problem becomes a problem when
someone becomes aware of it.
* there is always a pressure to solve the
problem.
* the person must have the
authority, information, or resources
needed to solve the problem.



                                        Page 8
Step 2: Identify the Decision Criteria
 • Decision criteria are factors that are
   important ( relevant) to resolving the
   problem.
   * Costs that will be incurred (investment
   required).
   * Risks likely to be encountered ( chance
   of failure).
   * Outcomes that are desired ( growth of
   the firm).

                                           Page 9
Step 3: Allocating Weights to the
             Criteria
• Decision criteria is of equal importance:
  * Assigning a weight to each item.
  * Places the items in the correct priority
  order of their importance in the decision
  making process.



                                               Page 10
Step 4: Developing Alternatives

• Identifying viable alternatives.
  * Alternatives are listed ( without
  evaluation) that can resolve the problem.




                                      Page 11
Step 5 :Analyzing alternatives


• Appraising each alternative’s
  strengths and weaknesses
  * An alternative’s appraisal is based
  on its ability to resolve the issues
  identified



                                      Page 12
Step 6: Selecting the alternative

   • Choosing the best
     alternative
     * The alternative with the
        highest total weight is chosen.



                                     Page 13
Step 7: Implementing the
           Alternative

• Putting the decision to and gaining
  comment from those whose will carry
  out the decision.




                                   Page 14
Step 8: Evaluating the decision’s
            effectiveness

• The soundness of the decision
   is judged by its outcomes.
  * How effectively was the problem
  resolved by outcomes resulting from
  the chosen alternatives?
  * if the problem was not resolve, what
  went wrong?
                                           Page 15
Intuition

* It is making decisions on the
basis of experience, feelings, and
accumulated judgment.




                                 Page 16
Decision Making Conditions

• Certainty
  * A situation in which someone can make
  an accurate decision because the
  outcome of every alternative choice is
  known.
• Risk
  * A situation in which the someone is able
  to estimate the likelihood (probability) of
  outcomes that result from the choice of
  particular alternatives.
                                           Page 17
• Uncertainty
  * limited information prevents estimation of
  outcome probabilities for alternatives
  associated with the problem and may force to
  rely on intuition, hunches, and ―gut feelings‖.
   # Maximax: The optimistic person’s choice to
  maximize the maximum outcome.
   # Maximin: The pessimistic person’s choice to
  maximize the minimum outcome.
    # Minimax: The choice to minimize maximum
  regret.
                                            Page 18
Types of Decision Makers
* Directive
  # Use minimal information and consider few
alternatives.
* Analytic
  # Make careful decisions in unique situations.
* Conceptual
  # Maintain a broad outlook and consider many
alternatives in making decisions.
* Behavioral
  # Avoid conflict by working well with others and
being receptive to suggestions.
                                               Page 19
Rational (Logical) Decision Model
Steps
Scanning the situation—identifying a signal that a
 decision should be made.

Classify the decision as routine, apply the
 appropriate decision rule; as non-
 programmed, begin comprehensive problem
 solving.

Monitor and follow-up as necessary.

Trends in Decision Making

– The pace of decision
 making is accelerating:
 more decisions to make
 and have less time to make them.
  • Complex streams of decisions
  • Sources of decision complexity
  • Perceptual and behavioral decision traps

                                       Page 21
Dealing with Complex Streams
           of Decisions
– Multiple criteria to be satisfied by a decision.
– Intangibles that often determine decision
  alternatives.
– Risk and uncertainty about decision alternatives.
– Long-term implications of the effects of the
  choice of a particular alternative.
– Interdisciplinary input increases the number of
  persons to be consulted before a decision is made.


                                                 Page 22
– Pooled decision making increases the
 number of persons playing a part in the decision
 process.
– Value judgments by differing participants
 in the process create disagreement over
 whether a decision is right or wrong, good or
 bad, and ethical or unethical.
– Unintended consequences occur because
 the results of purposeful actions cannot always
 be predicted.

Guidelines for effective
          decision making
 Categorical interpretation- the problem should be
  defined properly.
 Application of limiting factor- limiting factor
  should be taken into account in order to analyze
 Adequate information- more quantity of reliable
  information leads to effective decision making.
 Considering other views- various views at the
  same point are taken into account for quality
  decision.
 Timeliness- decision should be ,made at proper
  time to meet the competitive advantages.

Techniques improving decision
              making
 Brainstorming – idea generation for decision
  making.
 Nominal group technique (NGT)- problem
  outlined, presentation of solution in written
  form, discussion over written solutions, and final
  decision.
 Delphi technique- decision made on the basis of
  questionnaire filled by the respondents.
 Consensus mapping- decision made on the basis
  of the report presented by the representative of
  each group after                                 Page 25
