What role does a flow play in a Pega application?

A flow in a Pega application primarily serves the function of modeling the sequence of tasks in a process. This is fundamental to the way Pega applications are designed, as flows dictate how various tasks are executed in order, how work is routed among users, and how different actions are triggered based on business rules.

When you create a flow, you are essentially outlining the steps that a case or process will follow from creation to completion. Each stage within a flow can include decision points, automated actions, and manual tasks that form a structured approach to handling business processes. This allows organizations to automate workflows effectively, improving efficiency and ensuring consistency in operations.

Understanding how flows operate is crucial for designing effective Pega applications, as they are the backbone that ties together user interactions, backend processes, and system integrations. This aspect of flows enhances the overall functionality and user experience within the application.
