multi-instance lane?

DM

David Maurer on May 23, 2019

Hi everyone,

I have one pool for my organization. Within that pool I have 2 lanes, i.e.:

- financial service

- production unit

But in fact we have several "production units" and each one interacts in the same way with the financial service. Hence only one lane is needed.

So I was looking how to indicate that the "production service" is multi-instance, just like we can do it at pool level.

But I don't find possibility to do so for a lane object: is this not allowed in ARIS and/or BPMN?

If indeed not possible, what is then the next best option: renaming my lane from "production unit" to "production units"?

Thanks in advance!

Hello David,

for BPMN a Lane actually isn't an object with any practical purpose but layout. So you should not worry about cardinalities of Lanes. Apparently you decided to use the Lanes for roles. So if you think of production unit as a role you do not need to care about which org. unit acts in the role of production unit.

If you use the model type Enterprise BPMN Collaboration you can use a role lane, which actually represents your "production unit" role. No need to worry about cardinalities. Any production unit will do the job.

EDIT: BTW: A pool does not represent an organization, but a process. BPMN is not about organizational modelling (out of scope, see chapter 7.2 of the spec). Chapeau, if you manage to describe your entire organization in a single pool. Usually you do a Pool for every process and show the collaboration inside your organization as collaborating processes (Pools) exchanging messages in BPMN Collaboration diagrams.
