?Why Decision-making
![Page 5: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/5.jpg)
Decision MakingAdministrative process based on decision making , decision making is based on choice whereas choice is based on alternatives.

The Decision-Making Process
Identifying a problem. Identification of Decision Criteria. Allocating weights to the criteria. Developing alternatives. Analyzing the alternatives, that can resolve
the problem. Selecting from alternatives. Implementing the selected alternative.
Evaluating the decision’s effectiveness.

The Decision Making Process
![Page 8: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/8.jpg)
Step 1: Identifying the Problem
Problem
A discrepancy between an existing and desired state of affairs.
![Page 9: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/9.jpg)
The decision making process begins by determining that a problem exists: that is, there is an unsatisfactory condition. This is frequently expressed as a disparity between what is and what should be.
Whether a decision is necessary or not depends on the administrator’s perception. What one person sees as a “problem” another may see as perfectly acceptable state of affairs. So, the decision process begins with administrator’s recognition that there is a gap between what is desired and what actually is.
e.g. Purchase a new Laptop
![Page 10: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/10.jpg)
Step 2: Identifying Decision Criteria
Decision Criteria
Criteria that define what's important or relevant in
resolving problem. Costs that will be incurred (investments required) Risks likely to be encountered (chance of failure) Outcomes that are desired (growth of the firm)
![Page 11: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/11.jpg)
Important Criteria
Criterion
Carrying Weight
Warranty
Battery life
Display Quality
Memory and Storage
![Page 12: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/12.jpg)
Step 3: Allocating Weights to the Criteria
Assigning a weight to each item places the items in the correct priority order of their importance in the decision making process.(1-10)
![Page 13: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/13.jpg)
Weights for Laptop (1-10)
Criterion Weight
Memory and Storage 10
Battery life 8
Carrying Weight 6
Warranty 4
Display Quality 3

Identifying viable alternatives Alternatives are listed (without evaluation) that can resolve
the problem.
![Page 15: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/15.jpg)
Step 5: Analyzing Alternatives
• Appraising each alternative’s strengths and weaknessesAn alternative’s appraisal is based on its
ability to resolve the issues identified in steps 2 and 3.
![Page 16: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/16.jpg)

Step 6: Selecting an Alternative
Choosing the best alternative The alternative with the highest total weight is
chosen.
The final step in decision making process takes place when all the alternatives have been enumerated and evaluated
against the decision criteria. This final step is the selection of the best alternative which has quantitatively been
determined.
![Page 18: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/18.jpg)
Evaluation of Laptop Alternatives Against Weighted Criteria

Step 7: Implementing the Alternative• Putting the chosen alternative into action.
Conveying the decision to and gaining commitment from those who will carry out the decision.
![Page 20: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/20.jpg)
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 resolved, what went wrong?
![Page 21: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/21.jpg)
![Page 22: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/22.jpg)
Decision Making Models
Rationality
Bounded Rationality
Intuition
![Page 23: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/23.jpg)
Rational decision-making model
Managers make consistent, value-maximizing choices with specified constraints.
Assumptions are that, decision makers: Are perfectly rational, fully objective, and logical. Have carefully defined the problem and identified
all viable alternatives. Have a clear and specific goal Will select the alternative that maximizes
outcomes in the organization’s interests rather than in their personal interests.
![Page 24: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/24.jpg)
Assumptions of Rationality
![Page 25: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/25.jpg)
Managers make decisions rationally, but are limited (bounded) by their ability to process information.
Assumptions are that decision makers: Will not seek out or have knowledge of all alternatives Will satisfice—choose the first alternative encountered
that satisfactorily solves the problem—rather than maximize the outcome of their decision by considering all alternatives and choosing the best.
Influence on decision making Escalation of commitment: an increased commitment to
a previous decision despite evidence that it may have been wrong.
Bounded Rational decision-making model
![Page 26: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/26.jpg)
The Role of Intuition
Intuitive decision making Making decisions on the basis of
experience, feelings, and accumulated judgment.
![Page 27: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/27.jpg)
What is Intuition?

Decisions in the Management Functions
![Page 29: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/29.jpg)
Types of Problems and Decisions
Structured Problems
Unstructured Problems
![Page 30: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/30.jpg)
Structured Problems Involve goals that are clear.
Are familiar (have occurred before).
Are easily and completely defined—information about the problem is available and complete.
Programmed Decision A repetitive decision that can be handled by
a routine approach.
![Page 31: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/31.jpg)
Types of Programmed Decisions
Policy A general guideline for making a decision about a
structured problem.
Procedure A series of interrelated steps that a manager can use
to respond (applying a policy) to a structured problem.
Rule An explicit statement that limits what a manager or
employee can or cannot do.
![Page 32: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/32.jpg)
Problems that are new or unusual and for which information is ambiguous or incomplete.
Problems that will require custom-made solutions.
Non-programmed Decisions Decisions that are unique and nonrecurring.
Decisions that generate unique responses.
Unstructured Problems
![Page 33: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/33.jpg)

Programmed versus Non--programmed Decisions
![Page 35: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/35.jpg)
Decision-Making Conditions
Certainty
Risk
Un-Certainty
![Page 36: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/36.jpg)
Certainty
A situation in which a manager can make an accurate decision because the outcome of every alternative choice is known.
![Page 37: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/37.jpg)
Risk
A situation in which the manager is able to estimate the likelihood (probability) of outcomes that result from the choice of
particular alternatives.
![Page 38: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/38.jpg)
Uncertainty
Limited information prevents estimation of outcome probabilities for alternatives associated with the problem and may force managers to rely on intuition, hunches, and “gut feelings”. Maximax: the optimistic manager’s choice to
maximize the maximum payoff
Maximin: the pessimistic manager’s choice to maximize the minimum payoff
Minimax: the manager’s choice to minimize maximum regret.
![Page 39: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/39.jpg)

![Page 40: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/40.jpg)
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.

Common Decision-Making Errors and Biases
![Page 43: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/43.jpg)
Decision-Making Biases and Errors
Heuristics Using “rules of thumb” to simplify decision making.
Overconfidence Bias Holding unrealistically positive views of one’s self and
one’s performance.
Immediate Gratification Bias Choosing alternatives that offer immediate rewards
and to avoid immediate costs.
![Page 44: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/44.jpg)
Anchoring Effect Fixating on initial information and ignoring subsequent
information.
Selective Perception Bias Selecting organizing and interpreting events based on
the decision maker’s biased perceptions.
Confirmation Bias Seeking out information that reaffirms past choices
and discounting contradictory information.
![Page 45: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/45.jpg)
Framing Bias Selecting and highlighting certain aspects of a
situation while ignoring other aspects. Availability Bias
Losing decision-making objectivity by focusing on the most recent events.
Representation Bias Drawing analogies and seeing identical situations
when none exist. Randomness Bias
Creating unfounded meaning out of random events.
![Page 46: Principles of Management](https://reader036.vdocuments.us/reader036/viewer/2022062304/568131e8550346895d984ab6/html5/thumbnails/46.jpg)
Sunk Costs Errors Forgetting that current actions cannot influence past
events and relate only to future consequences. Self-Serving Bias
Taking quick credit for successes and blaming outside factors for failures.
Hindsight Bias Mistakenly believing that an event could have been
predicted once the actual outcome is known (after-the-fact).
