Explanation:

Vroom expectancy motivation theory:

Whereas Maslow and Herzberg look at the relationship between internal needs and the resulting effort expended to fulfil them, Vroom's expectancy theory separates effort (which arises from motivation), performance, and outcomes. Vroom's expectancy theory assumes that behavior results from conscious choices among alternatives whose purpose it is to maximize pleasure and to minimize pain. Vroom realized that an employee's performance is based on individual factors such as personality, skills, knowledge, experience and abilities. He stated that effort, performance and motivation are linked in a person's motivation. He uses the variables Expectancy, Instrumentality and Valence to account for this.
