What is the maximum number of shapes that a flow rule should be limited to?

A flow rule should ideally be limited to a maximum of fifteen shapes to maintain clarity and manageability. Keeping the number of shapes within this range allows for a more organized flow, making it easier for business users and stakeholders to understand the process being modeled. As flows become more complex, they can become difficult to follow, which can lead to misunderstandings or errors in execution. A limit encourages designers to simplify their flows and, when necessary, break larger processes into sub-flows or child flows. This approach not only aids in comprehension but also promotes better maintenance and scalability of the business process over time.
