A solution for managing a service engagement is provided. A service delivery model for the service engagement is defined within an engagement framework. The engagement framework, and consequently the service delivery model, can include a hierarchy that comprises a service definition, a set of service elements for the service definition, and a set of element tasks for each service element. The set of element tasks can be selected from a set of base tasks, each of which defines a particular task along with its input(s), output(s), and related asset(s). As a result, service engagements can be managed in a consistent manner using a data structure that promotes reuse and is readily extensible.
