Leaky Bucket, Lasting Value: Prof. Fred Selnes on Customer Portfolio Management

Prof. Fred Selnes, Professor of Marketing at BI Norwegian Business School, shares key insights from his acclaimed book “Customer Portfolio Management: Creating Value with a Large Leaky Bucket of Customers.” Professor Fred Selnes challenges the traditional belief that firms should focus only on a small base of highly loyal customers. Using the powerful metaphor of a “large leaky bucket,” he shows that weak customers with low margins and high churn can still be highly valuable because their volume helps cover fixed costs and reduce average indirect costs per customer. The core principle is that as long as prices from these weak relationships exceed marginal variable costs, they contribute positively to profitability while enabling the firm to invest in stronger, deeper relationships. Drawing on cases like airlines, Amazon, and Apple, he illustrates how companies can systematically convert weak, single-product relationships into strong, multi-category relationships over time, creating both customer value and sustainable competitive advantage. This long-term portfolio lens demands robust customer data, nuanced segmentation, and top-management ownership of customer strategy, not just tactical marketing initiatives.
