"Business model" is a catch-all phrase that covers models of a wide variety of types, so we start the accompanying Executive Report with a taxonomy of business model types. The report then goes on to give examples of the various types of business models in our taxonomy. Next, the report goes on to examine some of the key changes required in enterprise architecture in recent years as a consequence of changes in business models. Finally, we look at several business model frameworks that the EA team can use to convert or translate business models into architectural descriptions.
