    The major motivation for using Enterprise Architecture Frameworks is certainly the desire of all actors in the company and across all phases of architecture development and use, to generate the greatest possible added value while at the same time minimizing costs by using good practice.

  • Have you ever listened to or even participated in an discussion on Enterprise Architecture?

Consequently discussions on Enterprise Architecture either tend to be wasted time or not effective since a great amount of time needs to be invested to get a common understanding on expertise and terminology.
