Since 1990s,Customer delivered Value (CDV) has been the focus in the management education field and the enterprise field and was considered as the new resource of competitive advantages.Some enterprises do not know clear about the market environment and their own capabilities,and they have some malpractices presented in their operation management,so they crash into error zone.For example,blindly pursuing the maximum of CDV causes profit declining,treating the customers equally without discrimination causes complains throughout the customers,paying attention to the exterior effect while neglect their interior management causes falling short of success for lack of a final effort,misusing of CDV can not win expected effect.Therefore,we should orient scientifically and establish a set of perfect interior management system using pertinent marketing stratagem.Only if they pay enough attention to the “CDV” theory and improve CDV as much as possible,the enterprises can possess of competitive strength and potential of continuous development.
