BPMN and ArchiMate - roles representation

[MarcinG]

Hello,

there is a very interesting article on instance classifiers on the Sparx Community site.
However, the question arises - if multiple Business Roles (defined with ArchiMate) may participate in single process defined with BPMN (swimlanes), then the classifiers won't be of much help.  Example - different approvers of Travel Request, or Purchase Order.  How would you then ensure traceability ?  I was considering using Generalization, potentially with addition of UML actor, that could then be reused also in other UML diagrams.
Could anyone share his view/way of dealing with such situation ?

Best regards
Marcin

For completeness, here's you link: https://community.sparxsystems.com/tutorials/808-the-power-of-instance-classifier

Well, Pools and Lanes are meant to be classified (with an actor). But you can not classify with more than one classifier. So a pool/lane represents a single classifier which leads your question ad absurdum.

You shouldn't use classifier for BPMN pools and lanes.
The BPMN profile define specific tagged values for these things.
Pool
- partnerRole or partnerEntity
Lane
- partitionElementRef

Also I think you better not mix BPMN and Archimate at this point.
I use BPMN PartnerRoles to use in Lanes and Pools.
Then you can add a trace from the PartnerRoles to your Archimate Business Roles, allowing for an n-m relation between BPMN PartnerRoles and Archimate Business Roles.

PS. Nice little EA trick: if you use the proper BPMN tagged values you can leave the name of the Pool/Lane empty. EA will instead show the name of the linked partnerRole/PartnerEntity  (or BusinessProcess if you use processRef on Pools).

Dank u wel Geert.  Very useful suggestion, indeed it allows n-m traceability, which I am after.

Unfortunately, ArchiMate is mandated upon us, and we have to use it for the high level EA.  On the lower levels, we can use BPMN for processes design/decomposition, and UML for real design work on software solutions.  Then we need traceability back and forth.

Thank you very much for your response, it is really helpful.
