Value flow is a type of connection used in business process modeling to represent the flow of value or information between different elements in a process. It shows how inputs are transformed into outputs, and how value is added or changed as the process progresses.
In a business process network, value flow connections can be used to illustrate how different processes interact with each other, and how value is exchanged between different business units or stakeholders. Value flow connections may also represent the flow of information or data between different systems or departments and can help to identify opportunities for process optimization or improvement.
