3. Decision Making Decision making: A choice between two or more than two alternatives is called decision the process by which managers respond to opportunities and threats by analyzing options, and making decisions about goals and courses of action. [email protected] [email protected]

8. Decision Making steps” Identify the Problem: When making a decision a person first needs to identify and define the problem or conflict. [email protected]

9. Decision Making steps: Identify Decision Criteria: When a problem identified, the decision criteria important to resolving the problem must be identified. That is, managers must determine what is relevant in making decision. [email protected]

10. Decision Making steps: Allocation of Weights to criteria: If the relevant criteria are not equally important, the decision maker must weight the items in order to give them the correct priority in the decision.  [email protected]

11. Decision Making steps: Development of Alternatives: The fourth step in decision making process requires the decision maker to list viable alternative that could resolve. The problem this is the step where a decision maker needs to be creative . [email protected]

12. Decision Making steps: Choose One alternative: After making all the alternatives, the next step in planning or in decision making is to evaluate these alternatives. Evaluation is required in order to select the best alternative for implementation. [email protected]

13. Decision Making steps: Implementation of the Alternative: After choosing best alternative decision in to action by conveying it to those effected and getting their commitment to it. [email protected]

14. Decision Making steps: Evaluation of Decision effectiveness: The last step the decision making Process involve evaluating the outcome or result of the decision to see if the problem is resolve. [email protected]

15. Types of Decision Making: Programmed Decisions: routine, almost automatic process. Managers have made decision many times before. There are rules or guidelines to follow. Routine situations Decision rules can be developed and applied Managers formulate decision rules so subordinates can make decisions Example: Deciding to reorder office supplies.

18. Types of Decision Making: 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. Poorly defined situations Decisions are complex Routine decision rules do not apply Trend is toward subordinates making more nonprogrammed decisions Example: Should the firm invest in a new technology?

23. Decision Making Models: 1 . Classical Model Or The Rational-Economic Model 2. Administrative Model Or Behavioral 3. Herbert Simon’s Model [email protected] [email protected]

24. Glossary Rationality: A type of decision making in which choices are logical consistent and maximize value. Bounded Rationality: Decision making that's rational but limited(bounded) by an individuals ability to process information. Intuition: Making decision on the basis of experience, and accumulated judgment. [email protected] [email protected]

25. Classical Model: ( The Rational-Economic Model) Classical decision theory assumes the manager faces a clearly defined problem, knows all possible action alternatives and their consequences, and then chooses the optimum solution Administrative Model ( Behavioral) ` Behavioral decision theory accepts the notion of bounded rationality. It assumes the manager acts only in terms of what is perceived about a given situation, and then chooses a satisfying solution. [email protected] [email protected] Decision Making Models:

26. Classical Model: ( The Rational-Economic Model) Assumptions Decision maker operates to accomplish goals that are known and agreed upon Decision maker strives for condition of certainty – gathers complete information Criteria for evaluating alternatives are known Decision maker is rational and uses logic The decision maker selects the optimum or best choice. Facts: 1. Goals are known and agreed upon. Problems are precisely defined 2. All alternatives and outcomes are calculated 3. Criteria evaluated and decision made maximizing return (expected value) 4. Uses rationality and logic. [email protected] [email protected]

27. Classical Model: Assumptions [email protected] [email protected] Problem clarity Known options Clear preferences Constant preferences No time or cost constraints Maximum payoff

28. Classical Model: ( The Rational-Economic Model) [email protected] [email protected]

29. Administrative Model ( Behavioral) Administrative model describes how managers actually make decisions including those that are: Non-programmed Uncertain Ambiguous Not Quantitative Used due to “Bounded Rationality” Decision goals often are vague, conflicting Rational procedures are not always used Managers’ searches for alternatives are limited [email protected] [email protected]

30. Administrative Model ( Behavioral) How Non-programmed decisions are made--uncertainty/ambiguity hence it is risky to take decision. 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. The decision maker selects a satisfying alternative Decision making proceeds sequentially: alternatives are examined one at a time and the first satisfactory alternative that is found is selected.

32. The Herbert Simon’s Model [email protected]

33. The Herbert Simon’s Model Intelligence Raw data collected, processed and examined. Identifies a problem calling for a decision. Design Inventing, developing and analyzing the different decision alternatives and testing the feasibility of implementation. Assess the value of the decision outcome. Choice Select one alternative as a decision, based on the selection criteria
