CWM12 — Inadequate support for Organizational Structures

Sections 8.3 and 8.3.1.7 justify ResponsibleParty inheriting from Namespace in that it can be used for "capturing organizational structures or similar relationships". This is not only quite obscure but is inadequate for even very simple and common Warehouse-oriented situations - due to the strict composition semantics of Namespace. In particular it does not allow a single person to belong to more than one Position/Team, nor does it allow the representation of matrix/management relationships which are very common. Moreover it does not allow the separation of two very different concepts: packaging of models and organizational relationships.

An example 'test' scenario is of 2 support teams: one for Corp Database A, another for Corp Database B. Both will always have the same Manager (regardless of who is currently filling that position) and make use the same Performance Specialist, John Wicks.

It is proposed that CWM adopt a simple but specific Organization Structure metamodel (no more than 5 classes such as Unit, Position, Person) that also aims for consistency with OMG's recently adopted Organizational Structure Facility.
