TOPIC: MANAGERIAL EFFECTIVINESS

This topic is pertinent both to social scientists concerned

with

behavior in the work situation and to those individuals who

occupy positions in the management of organizations. Itconcerns the relationship between the job attitudes of

managers

and their on-the-job performance.

(Managerial Attitudes, Preface)

VROOM’S VALENCE X EXPECTANCY THEORY

One of the most widely accepted explanations of motivation has been

propounded by Victor Vroom. His theory is commonly known as

Expectancy Theory. He argues that: the strength of a tendency to act in

a specific way depends on the strength of an expectation that the act will

be followed by a given outcome and on the attractiveness of that

outcome to the individual.

The theory focuses on three things :

Efforts and performance relationship

Performance and reward relationship

Rewards and personal goal relationship

THEORY OF EXPECTANCY

Motivation

Actions

Results

Satisfaction in form of rewards

THE THEORETICAL MODEL

L. Porter and E. Lawler developed a more complete version

of motivation dependent upon expectancy theory.

They developed a model --conceptual scheme to guide their

thinking-- relating effort, performance, satisfaction, and other

key variables.

This model led them to ‘some testable hypotheses.’

VARIABLES Value of Reward: refers to how attractive or desire is a potential outcome of an individual’s behavior in the work situation.

Effort- Reward Probability: refers to an individual’s perception of whether differential rewards are based on differential amounts of effort on his part in the work situation.

Effort: refers to the energy expended to perform some task, but does not necessarily correlate with how successfully the task is carried out.

Abilities and Traits: characteristics of individuals that remain largely unaffected by momentary changes in their environmental situation.

Role Perceptions: deal with the way in which the individual defines his job– the types of effort he believes are essential to effective job performance.

Performance: refers to a person’s accomplishment on tasks that comprise his job.

Rewards: are desirables states of affairs that a person receives from either his own thinking or the action of others.

Perceived Equitable Rewards: are defined as the amount of rewards that a person feels is fair.

Satisfaction: is defined as the extent to which rewards actually received meet or exceed the perceived equitable level of rewards.

THE THEORETICAL MODEL

RATIONALE OF METHODOLOGY

Co-relational Study: can sometimes disprove but never prove that a

causal relationship exists.

Questions:

1- Does satisfaction with pay lead to higher job performance?

2- Does an employee’s attitude regarding how his pay is determined,

influence his job performance?

1- YES AND NO

Social person?

Self-actualizing person?

Economic person?

The fact is that people is motivated by social

and self-actualization needs as well as

economic needs.

2- ATTITUDE “CHANGES”

Inner-Directed Cluster

Forceful

Imaginative

Independent

Self-confident

Decisive

Other-Directed Cluster

Cooperative

Adaptable

Cautious

Agreeable

Tactful

TYPES OF NEEDS

Security

Social

Esteem

Autonomy

Self-Actualization

REVISION OF THE MODEL

“It now appears that those types of needs which can be satisfied

primarily by intrinsic rewards - autonomy and self-actualization– are

more likely to produce attitudes about satisfaction that are significantly

related to performance than are needs—such as security and social

needs– which can be satisfied primarily by extrinsic rewards.”(p. 163)
