The business strategy can't be unchangeable, it must be adjusted with the change of internal conditions and external environment. Management must also have different management modes according to the enterprise's constitution and different stages. In an era of rapid changes in the world environment, the essence of business management is to adjust the business strategy serving the business strategy at any time. Therefore, we believe that the so-called business strategy refers to all the actions and action policies, schemes and competition modes that can be taken to achieve the business objectives under certain market environment in the enterprise management in order to achieve a certain business objective. It sets out the actions to be taken in a situation that may be met and may occur. As the business strategy is a arduous creative activity of brain use and rational thinking, the correct use of business strategy should meet three conditions: first, we should take actions in order, which can not be modified or followed in the future, and which should not be called business strategy. Second, what will happen in the future is uncertain. If what may happen is certain, there is no need to formulate business strategies. The third is that the uncertainty of occurrence decreases with the acquisition of information, and we need to respond to the information of the original uncertainty in time. In practice, due to the frequent occurrence of these three conditions, the work of making business strategy is quite complicated.
