Each customer is an investment and represents hours of marketing efforts and expenditures. Each customer lost represents an investment that is no longer reaping dividends. Having customers, not merely acquiring customers, is crucial for business success.
In an article in the Journal of Marketing Research titled “Defensive Marketing Strategy by Customer Complaint Management: A Theoretical Analysis” by Claes Fornell and Birger Wernerfelt, numerous successful marketing strategies are identified. According to the authors, one crucial feature of marketing strategy is the company’s ability to identify and influence the flows of customers in and out of its franchise and into and out of the market. Fornell and Wernerfelt identify these flows as consisting of:
1) additional customer entry to the market,
2) brand shifting or change of patronage,
3) customer market exit, and
4) changes in purchase frequency.
