Secondary actors

General Questions/Discussions
1

HI VP Team,

I was wondering how I can define a secondary actor in the use case details.
eg. Primary = Customer, secondary = Bank

So for use case like pay bill via internet, I have my customer pay their bill though my website (system) and then I communicate with the bank.

I’ve noticed in the basic flow there is only one actor, and the sequence diagram is only able to a single actor and the system, even though I have defined a secondary actor.

Any suggestions?

Cheers

Hello gpriestley,

I suppose you are talking about the flow of events. The flow of events represent only the interaction between primary actor and the system. Sometimes, secondary actor can be seen as a part of the system. If this is not possible, you should use sequence diagram instead.

Best regards,
