This document discusses the growing importance and maturation of the customer success field. It emphasizes that customer success should be run like a business using portfolio management techniques. Customer relationships should be viewed through the lens of lifetime customer value and segmented into a portfolio of customers at different stages from new to at risk of churn. The optimal engagement model focuses on driving outcomes through programs tailored to each customer segment rather than taking a one-size-fits-all approach. Metrics should be used to track key drivers, results and risks to the customer portfolio. Ultimately, the goal is to manage customer relationships like tending a grove, not taking a hunting approach, to maximize long-term customer lifetime value and business success.
