In a case life cycle, what defines actions and roles associated with each stage?

The case type is essential in defining the overall structure of a case life cycle, including the actions and roles associated with each stage. It acts as a blueprint for how a specific type of case is managed within the Pega platform. Each case type outlines the series of interconnected stages, processes, and milestones that form the framework for case management.

Within a case type, individual stages represent key points in the life cycle where specific actions occur, and distinct roles may be assigned to individuals or teams responsible for those actions. This includes defining which users engage with the case, what tasks they perform, and how they interact with system processes throughout the life cycle.

The other options focus on components of case management. The process refers to the flow of work within a case or the specific steps taken. Activities are specific tasks or actions that can occur within a process or as part of a case. Assignments relate specifically to the tasks assigned to users but do not capture the broader context of defining roles and actions throughout the entire case life cycle like a case type does. Therefore, the case type is the correct answer as it comprehensively encompasses all elements needed to outline a case's structure and flow.
