The Coherent EA is a change oriented Enterprise Architecture approach base on the concept of continuous change. It taking the time dimension into consideration and suggest that an enterprise is changing continuously. The change oriented EA model is initiated to clarify major myth in the EA community as has evolved to emphasize on reference model and service oriented architecture to enable simplicity and agility, Segment Architecture to close the gap of business performance to address business change base empirical need. EA has not evolved as expected because there is a great confusion on What is EA, what is reference model, the role of service oriented architecture and the purpose of segment architecture due lack of a update EA model to keep up with the EA evolution. The community try to understand EA from the traditional application development oriented EA approach. CEA suggest a change oriented enterprise architecture approach which break the myth of target enterprise architecture and clearly explain what is reference model, the role of service oriented architecture and the purpose of segment architecture.
