The success or failure of an enterprise, it has connected with the enterprise staff. Modem enterprise to make the enterprise in the competitive market of the brand is enduring, its survival is to be active play to the initiative, enthusiasm and creativity of employees, emphasizing the subject status of the employees and the leading role which is to emphasize the importance of basic management in enterprise management. Our research provides managers with the state-of-the-art methodology of management which will enhance the overall performance and the efficiency of business operating.展开更多
