Key Topics

Page 3: Handout 2 - Decision Making

Part I

Introduction

Page 4: Handout 2 - Decision Making

Organizations are systems

Involve people, structure and a common purpose

Have limited resources

Need to perform a series of functions to meet its objectives

Organizations

Page 5: Handout 2 - Decision Making

Managers are responsible for effective and efficient execution of these organizational functions.

A typical manager performs a number of functions that are categorized as:

• Interpersonal

• Informational

• Decisional

Managers

Page 6: Handout 2 - Decision Making

One of the key traits that distinguish managers from operatives is the ability to make independent decisions.- self determining. Decide traits.

Managers

Page 7: Handout 2 - Decision Making

Part II

Decision-making

Page 8: Handout 2 - Decision Making

The word decision is defined as:

“A choice between two or more alternatives”. Maraming pagpipilian

Thus decision-making can be defined as:

“the selection of a course of action from among alternatives ”. Select action from alternatives

What is decision-making?

Page 9: Handout 2 - Decision Making

Identifying a problem

Identifying decision criteria

Allocating weights to criteria

Developing alternatives

Analyzing alternatives

Selecting an alternative

Implementing the alternative

Evaluation (of decision effectiveness)

Decision-making Process

Page 10: Handout 2 - Decision Making

Problem is a discrepancy (difference) between an existing and a desired state.

Example:

“The manager has resigned, and we need another manager”

Here the phrase “manager has resigned” reflects the current state while “need another manager” represents a desired state.

Problem Definition

Page 11: Handout 2 - Decision Making

The word criteria, is defined as “a standard by which something can be judged”.

A decision criteria therefore, is the basis of a decision, which outlines the relevant and important factors for a decision. And implicitly, it also defines what is not important.

Identifying Decision Criteria

Page 12: Handout 2 - Decision Making

In the above-cited scenario, the decision criteria may include the following factors:

Relevant qualifications

Leadership skills

Communication skills

Planning and analytical skills

Professional experience

Decision Criteria: Example

Page 13: Handout 2 - Decision Making

The next step in the decision making process is prioritization.

Prioritization is achieved by assigning quantitative weights to each criteria element.

The weightage defines the relative significance of each element.

Allocating Weights to Criteria

Page 14: Handout 2 - Decision Making

Criterion Weight

Relevant qualifications 3

Leadership skills 5

Communication skills 3

Analytical skills 4

Professional experience 1

Allocating Weights: Example

Page 15: Handout 2 - Decision Making

Involves defining the possible alternatives (or choices) that would resolve the problem.

In our case, the alternatives would be a list of candidates or job applicants.

Developing Alternatives

Page 16: Handout 2 - Decision Making

Alternatives are rated and analyzed on the basis of the criteria

The rating can be based on a specified scale, say 1 – 5 etc.

Rating may be subjective in nature and thus,may depend on the judgment of the individual(s)

Analyzing Alternatives

Analyzing & Assessment: Example

Page 19: Handout 2 - Decision Making

Involves choosing the best alternative, based on the above rating and analysis

Generally implies selecting the alternative with the highest score.

Selecting an alternative

Page 20: Handout 2 - Decision Making

Putting the decision into action

Involves clear communication of the decision to all concerned and obtaining their commitment

Implementing the Alternative

Page 21: Handout 2 - Decision Making

Evaluation forms an integral part of any process

Involves evaluation of the outcome based on the desired goal and criteria

Involves assessing the effectiveness and efficiency of the outcome (or the entire process)

In case of any undesired results, each step of the process is carefully reviewed to trace the root causes

Evaluation

Page 22: Handout 2 - Decision Making

Model

“A simplified representation or description of a system or complex entity”

Examples

A model of a building

A globe (Earth model)

Decision-making Models

Page 23: Handout 2 - Decision Making

So Rational and Bounded Rational Models are cognitive models that describe how managers make rational decisions

Rational/Bounded Rational

Page 24: Handout 2 - Decision Making

2. Set goals

The Rational Model

External and internal Environ. forces

1. Define and diagnose the

problem

3. Search for alternative solutions

4. Compare and evaluate

solution

5. Choose among

alternative solutions

6. Implement the solution

selected

7. Follow up and control

2. Analyze the problem

Page 25: Handout 2 - Decision Making

Not all decisions made on rational basis

Most problems, goals and preferences are not clear or well defined

Not practical to know all possible alternatives

Time and cost constraints exist in all practical problems

Result not maximized in most cases

Rational Model: Criticism

Page 26: Handout 2 - Decision Making

Limited set of criteria

Self-interest influences ratings

Limited no. of alternatives

Alternatives are assessed one at a time till a satisficing (or good enough) alternative is found

Politics influences acceptance and commitment of decision

Bounded Rational: Assumptions

Page 27: Handout 2 - Decision Making

An unconscious process of making decisions on the basis of experience and judgment

Intuition

Page 28: Handout 2 - Decision Making

Involves gut feeling

May also have rational basis

The “feeling” arises from past experience and knowledge

Involves quicker response

Does not involve systematic analysis

Intuition

Page 29: Handout 2 - Decision Making

Effective managers make various kinds of decisions. In general, these decisions are either

Programmed decisions

Non-programmed decisions

Decision Types

Page 30: Handout 2 - Decision Making

A decision that is repetitive and routine

A definite method for its solution can be established

Does not have to be treated a new each time it occurs

Procedures are often already laid out

Examples: pricing standard customer orders, determining billing dates, recording office supplies etc.

Programmed Decisions

Page 31: Handout 2 - Decision Making

A decision that is novel (new or unique) or Ill structured

No established methods exist, because it has never occurred before or because

It is too complex

Non-programmed Decisions

Page 32: Handout 2 - Decision Making

Non-programmed Decisions

Organizational Levels

Nature ofProblems

Nature ofDecision-making

Page 33: Handout 2 - Decision Making

Are “tough” decisions that involve risk and uncertainty and

call for entrepreneurial abilities

Such decisions draw heavily on the analytical abilities of the manager

Examples: Moving into a new market, investing in a new unproven technology, changing strategic direction

Non-programmed Decisions

Page 34: Handout 2 - Decision Making

Decision-making, though a rational process does include some subjective elements

Thus in real organizational settings, the quality of decision does depend on the ability, style and approach of the manager

Decision Styles

Page 35: Handout 2 - Decision Making

Directive

Represents low tolerance for ambiguity and uncertainty

Reflects rational thinking of the manager

Such decision styles are more suitable for routine procedural tasks

Decision Styles: Directive

Page 36: Handout 2 - Decision Making

Analytic

Analytical style is also a rational style of thinking

Involves a very high tolerance for ambiguity and uncertainty

Such managers generally seek detailed information before making a decision

Decision Styles: Analytic

Page 37: Handout 2 - Decision Making

Behavioural

Represents a creative way of thinking

Involves a low tolerance for ambiguity or uncertainty

Managers with a behavioural style introduce “new” ways of doing things

Decision Styles: Behavioural

Page 38: Handout 2 - Decision Making

Conceptual

Conceptual style also reflects a creative and intuitive way of thinking

Conceptual style managers have a very broad vision and generally look at numerous alternatives for decision-making

Focused on the long run and often result in creative outcomes or alternatives

Decision Styles: Conceptual

Page 39: Handout 2 - Decision Making

The factors requiring group decisions include:

Involving sensitive issues

High cost alternatives

Involving very high risk factor

Strategic impact

Group Decision-making

Page 40: Handout 2 - Decision Making

Acceptance of group members

Coordination is easier

Communication is easier

Existence of large alternatives

More information can be processed

Diversity of experience and perspectives

Group Decisions: Advantages

Page 41: Handout 2 - Decision Making

Take longer time

Group can be indecisive

Groups can compromise

Groups can be dominated

Groups can “play games”

Victim to Groupthink

Group Decisions: Disadvantages

Page 42: Handout 2 - Decision Making

Unimportant to group

Manager can take decision

Dominate the decision

Destructive conflict

Members hesitant
