Usage Is Not Value
High login frequency can look healthy while the customer’s real business outcome remains unchanged. Customer success professionals connect behaviour to the result the buyer cared about in the first place.
Scenario: Adoption Is High but Renewal Is at Risk
Check whether users are achieving meaningful outcomes, whether senior stakeholders can see that value, whether the budget owner still supports the programme and whether the customer has a credible alternative. Adoption is one signal, not the whole account.
