According to hertzberg's research,

According to hertzberg's research, managers should recognize that the health factor is necessary, but it does not produce a more positive effect once and after the dissatisfaction. Only "motivators" can make people perform better at work.Two-factor theory tells us that the depth and effect of stimulation caused by satisfying various needs are different. The satisfaction of material needs is necessary, and its absence can lead to dissatisfaction, but even if it is satisfied, its effect is often very limited and unsustainable. To mobilize the enthusiasm of people, not only to pay attention to material benefits and working conditions and other external factors, more important is to pay attention to the arrangement of work, use, personal growth and ability improvement, pay attention to spiritual encouragement, give praise and recognition, pay attention to give people to grow, development, promotion opportunities. As people's material "well-off" problem is solved, people's spiritual "well-off" demand is more and more urgent.3. Expectancy theory. American psychologist frum put forward the theory of expectation in 1964. According to the theory, the power of stimulation comes from the product of potency and expected value, that is, the utility of stimulation = expected value × potency. That is to say, the force that drives people to achieve their goals is the product of two variables, and if one of them is zero, the utility of the incentive is zero. Valence is a subjective estimate of the benefits or value to the individual and the size of the value after the enterprise and the team's goals have been achieved. Expectation is a subjective estimate of the possibility of achieving the enterprise goal and the possibility of fulfilling personal requirements after the enterprise goal is achieved. These two estimates are constantly revised and changed in the course of practice, which is called "emotional adjustment". For example, I think I have the ability to complete this task. After I finish the task, I estimate that the boss will surely honor his promise to give me a promotion. On the contrary, the change of any variable will affect the work enthusiasm. The task of the manager is to make this adjustment conducive to achieving maximum motivational power. Therefore, expectation theory is a process incentive theory.
