Motivation is not usually responsive to manipulation. Positive motivation most often arises when the employee feels he is genuinely an important part of the picture or the job. Such feelings usually result from involvement and participation. Strong motivation rises out of a strong feeling of self worth. Management can be most effective by creating an environment which enhances feelings of self worth, involvement, recognition, responsibility, advancement and growth.
Incentive is an outward influence which causes certain behavior to take place.
In many cases incentives can be used to bring about quick changes. The improvements may tend to disappear when the rewards no longer come. Sometimes the level of reward must be continually increased in order to be effective. An effective manager will understand the differences and value of motivation and incentive. He will appreciate the appropriateness of both forms of influence.
