What are the two primary types of user interactions in Pega applications?

The two primary types of user interactions in Pega applications are indeed task and case management. Task management involves setting up specific activities that users need to complete, often in relation to a larger process, while case management encompasses the overall handling of a case or request, which may require multiple tasks to be accomplished by different users or teams.

In Pega, case management serves as the backbone of enterprise applications, organizing work into manageable pieces, or cases. Each case can have its own unique workflow, which includes various user tasks that need to be performed. This creates a structured environment where activities related to a case can be tracked and managed effectively.

Considering the other options, input and output management does not accurately represent the types of user interactions, as they are more focused on data processing rather than the user actions within the framework. Similarly, case management and data management is not a primary interaction type; while data management is essential, it is not a user interaction in the same way that tasks and cases are. System and user interaction lacks the specific detailing of the functional roles that task and case management provide in structuring user experiences and workflows within Pega applications.
