Katz curve tells us that organizations, like people, have a process of growth, maturity and decline. The optimum age range of an organization is 1.5 ~ 5 years old. After five years, the organization will age. The solution is to reorganize the organization through the flow of talents. Katz's organizational life theory proves the necessity of employee mobility and talent withdrawal from the perspective of organizational vitality. At the same time, it is also pointed out that the personnel flow is not easy to be too fast, and the flow interval should be more than 2 years, which is the lower limit time needed to adapt to the organizational environment and complete a project. Generally speaking, it is ok for a person to move 7-8 times in his life, but too many times will reduce the income.
