State changes between Use Case Initiator & Receiver actors 

I would like to know what's the best way to model a  situation when both initiator and a receiver actors are involved in a Use case.

- initiator sends a request for contact exchange (the inititator has a contact on pending state)

- receiver approves the contact exchange (the receiver has a contact on active state)

- initiator receives a confirmation (the inititator has contact on active state)

 

My ideas would be:

-  state diagram for "Contact" object - but that will only reflect the changes only for one Actor.

- BPMN diagram to reflect the process flow for both Actors

 

Is this enough or there is another diagram I can use?

Also, these diagrams focus on the main scenario but the alternatives how should be described in a diagram?

Thanks!

 Hi Madalinaro,

Looks to me like you have a process with at least 2 use cases. 

Use case #1: Initiator "Request Contact Exchange"

Use case #2: Receiver "Approve Contact Exchange" with the initiator getting a confirmation.

expect each use case has alternate scenarios, etc.

So your deliverables are:

1. The two use cases with alternate scenarios

2. business process diagram - bpmn or activity diagram

3. Statechart diagram for the contact class

4. You could even specify the business domain model using a class diagram to show the "contact" class and related classes.

It'd be overkill for your example but I expect you've simplified it hugely.

Re: State changes between Use Case Initiator & Receiver actors 

Thank you, this clarifies a lot!

It's true, the flow I described here is hugely simplified; in reality there are more steps plus alternative scenarios
