To be able to view our business from different views we need different model types. Requirements and needs are structured in requirement models, roles and competence in organizational models and flows in process models. By grouping all these models toghether in a repository, we ensure that we are using the same objects in our different models, and are able to navigate easily between the models. We can go directly from the requirement model to the process model fulfilling the requirements, or from the process model to the organization model where the performing roles are structured. And so on.
