Aggregation in Hierarchy
Hi everyone,
I would like to ask your opinion on the use of aggregate relations in describing hierarchies in an organizational structure. I think it's perfectly fine to use:
Company Composed of Department 1 and Department 2
Holding Aggregation of Company 1 and Company 2
But it seems illogical to me to use:
CEO Aggregation of Deputy1 and Deputy2
Although Archimate formally allows you to use this relation for objects of the same type (Role), in my opinion it does not describe the nature of this relation, because CEE is not entirely made up of deputies.
Nevertheless, in many such cases, the Aggregation relation is used in this way. I think it would be better to use a Serving or Association relations
Thanks for the feedback
Ivan
