Customer portfolio management (CPM) for improved customer relationship management (CRM): Are your customers platinum, gold, silver, or bronze?

The purpose of this article is to contribute to the body of customer relationship management (CRM) literature by introducing a conceptual framework of the customer portfolio management (CPM) matrix, which focuses on two issues: (1) cost to serve and (2) value of the customer to the company. From this framework, a firm can segment its customer base into four portfolios, platinum, gold, silver, and bronze, and deliver services accordingly.
