Vroom's VIE (expectancy) theory

Victor Vroom (1964) proposed the expectancy theory (VIE theory). It states that a person is motivated to put effort when he believes that effort will lead to good performance, performance will lead to rewards, and the rewards are valued.

Motivation (Force) = Valence × Instrumentality × Expectancy

• Expectancy (E): Belief that effort leads to performance. "If I try hard I can finish this software on time." Value between 0 and 1.
• Instrumentality (I): Belief that performance will lead to a reward. "If I finish on time I will get a bonus or promotion."
• Valence (V): The value or attractiveness of the reward to the person. A bonus has a high valence for someone who needs money.

Effort --E--> Performance --I--> Reward --V--> Satisfaction

If any one factor is zero, motivation is zero. For example, if employees think promotion in a public enterprise depends on political connections (low instrumentality), they will not work harder, even if the promotion is attractive.

Importance of reward in the theory

1. Valence depends on reward: Only rewards the employee values create force.
2. Link of performance and reward must be visible: Fair, transparent appraisal builds instrumentality.
3. Variety: Different employees value different rewards (pay, recognition, growth), so choose appropriately.
4. Fairness: Unfair rewards reduce belief and motivation.
5. Timeliness: Rewards should follow performance soon.

Managerial implications: clarify goals, give training so employees believe they can succeed, link pay to performance, and know what employees value.

Criticism: complex, assumes rational calculation, hard to measure the variables.
