What is an architecture?
Have you ever listened to or even participated in an discussion on Enterprise Architecture? You might have recognized that the participants in the discussion had no common sense on the meaning of Architecture to start with, most often than not without even knowing about this lack of common sense.
Reasons are often not a lack of individual expertise but a lack of common expertise and common terminology. 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.
