- For a given pillar, it is suggested to model layers top-down, modelling high level before full detail, and platform-independent business models before platform-specifics
- Each model artifact will be located in a specific pillar and layer.
- the AIDM also needs to be able to offer differentiated views ( often diagrams ) to various stakeholders, introducing a 3rd dimension
