Which of the following is an optional action that can increase usability of a case management system?

The option that enhances the usability of a case management system through optional actions is the transfer of cases between employees at any stage. This functionality provides a level of flexibility and responsiveness within the system, allowing for smoother transitions and better resource management, especially in environments where team members may have varying workloads or expertise.

By facilitating case transfers, the system can maintain momentum on cases that may require different skill sets or have become unmanageable for the original assignee. This optional action supports a collaborative work environment where cases can adapt to the changing dynamics of team availability, ensuring that the most relevant resources can address cases based on their current context.

Enhancing usability in this way can lead to improved efficiency, as well as increased employee satisfaction by reducing the burden on any one individual and allowing for better overall performance. The ability for employees to easily transfer cases as needed streamlines workflows and can lead to faster resolutions.

In contrast, other options contribute to usability but do not specifically enhance the dynamic management of case assignments in the same way. For instance, an even distribution of workload is important for fairness, while the ability to attach documents and automatic notifications are valuable features. However, they do not provide the same level of flexibility and operational advantage as allowing case transfers.
