A sprint that is focused on the production of results that a customer would deem valuable. As a rule, all sprints should produce customer value. However, during the initiation of a new product or project (i.e., during product-level planning / envisioning), there might be work (possibly organized into sprints) that is focused on the acquisition of information that would be helpful to determine whether or not the product should be funded. For example, work to validate an important assumption that is a critical factor in approving/moving forward with the development of the product. Such work, if done in sprints, would not be customer-value-creation sprints since they do produce results that would be valuable to the end-customer.
