A business analyst (BA) is working on a payment system (PS) implementation. A set of systems which should interact with a new system has been identified. The business analyst defined that a user with role of
"Supervisor" in the PS must pass a two-factor authentication before an execution of the functions: "Change system parameters" and "Set up new supervisor." A user must have the role of "Supervisor" to use the standard functions "Send mail notification" or "Send SMS notification".
The BA defined the following use cases:
*"Change system parameters"
*"Setup new supervisor"
*"Send mail notification"
*"Send SMS notification"
*"Send notification"
*"Pass a two-factor authentication"
The BA wants to create a Use Case diagram.
What standard relationship should be defined between "Change system parameters", "Setup new supervisor" and "Pass a two-factor authentication"?
