A high-level enterprise architecture model that only includes key concepts and
key relations forms an appropriate means of communication with the stakeholders
in the early stages of the modelling process: not only does it show the key concepts
and relation, but also it forms a basis to discuss the purpose and scope of the
modelling process. It is of the utmost importance to agree with the stakeholders on
the key concepts and key relations, as these make up the framework on which the
rest of the enterprise architecture model is based.
After reaching an agreement on this high level of abstraction, you can use
various other levels of abstraction to specify the enterprise architecture model.
Each of these levels zooms in on a specific part of the higher-level model and allows
you to add detail. To benefit from the use of different levels of abstraction, you have
(formally) to identify the levels, each with a well-defined scope, and maintain
consistency among the levels (Biemans et al. 2001).
