   A modeler is linking a requirement that says 'the system shall process the payment.' The requirement does not specify which payment methods are supported.

   • AModel only the most common payment method to keep the model simple.
   • BSkip the payment requirement until the stakeholder decides.
   • CModel a generic 'payment' action and document that the specific methods are pending stakeholder decision.
   • DModel all known payment methods to maximize coverage.
