4 important questions on EA frameworks, modelling and tools - Notes on EA modelling

What is important concerning EA modelling?


Whether an EA framework is applied or not, it is essential that the EA is documented. EA practitioners consider a collection of artefacts sufficiently complete to describe an enterprise in useful ways as constituting an EA model. EA models illustrate architecture descriptions.

What is the difference between EA modelling and business process modelling?


Contrary to pure business process modelling, architecture descriptions are more comprehensive.
An organisation can start off with a data and process modelling initiative.
