Which approach is focused on assessing the efficiency of services?

The correct choice focuses on assessing the efficiency of services by emphasizing structured roles and responsibilities within the case management process. Role-based case management ensures that each team member's contributions are well-defined, promoting accountability and streamlining workflows. This approach allows for a clear evaluation of how services are delivered, enabling the identification of any inefficiencies or gaps in the system.

By concentrating on the roles of different professionals involved, it provides a framework through which outcomes can be measured effectively. This leads to improved service delivery by highlighting strengths and weaknesses in the existing processes.

In contrast, other approaches may focus more on the individual needs of clients, the organization's overall framework for service delivery, or the responsibilities of the case managers themselves, which are less centered on measuring service efficiency.
