What shape is used to indicate a smaller process within a flow rule for reuse?

The subprocess shape is specifically designed to indicate a smaller process within a flow rule for reuse. This shape allows developers to encapsulate a sequence of steps that can be reused in multiple flow rules without duplicating the logic. By using the subprocess shape, developers can promote modular design and maintainability in their applications, as changes made to the subprocess will automatically reflect wherever it is reused.

The subprocess shape serves as a visual representation of this reusable logic, making it clear to anyone reviewing the flow that this section is a distinct and call-able segment of the overall process. This approach helps streamline development and can significantly reduce complexity in larger applications by breaking down processes into manageable components.
