Misconception No. 1: “Finally the One Key Figure Which Replaces All Others and Can Serve as the Basis for All Marketing Decisions!”
Rather not. The customer lifetime value is not the big simplifier for which it is sometimes taken. It sums up the expected turnovers with a customer within a certain period of time, which can vary from a few weeks up to several years according to application and industry. Thus, it provides good services for the evaluation of distribution channels or the measurement of the long-term success of marketing measures. In this process, it will at best modify but not displace older marketing key figures. Due to its name, the customer lifetime value virtually invites connotations with the most diverse ideas of customer value. Anyone wishing to effectively work with the customer lifetime value, however, may not use it as projection surface for his/her own ideas of customer value. As for any other key figure, it is the definition, which specifies the interpretation possibilities, not the name.
