This section explains the method to visualize the abstractive and invisible enterprise. Enterprise Architecture without visualize the Enterprise can not really constitute an EA practice. Enterprise is invisible and abstractive concept which up to every one’s imagination. . A frequent challenge of Enterprise Architects from customers is “Show me the enterprise?”.
THE APPROACH TO SEE THE BIG PICTURE
Enterprise Architecture enables every one to see the invisible enterprise big picture. LEA suggest to see the enterprise big picture in the following model by using the following techniques.
. Concept of Operation
. Enterprise Architecture Frameworks.
. Enterprisse maps
. Architecture drawings.
It use the simple graphic of Concept of Operation ; Provide framework as a thinking tool and visualize the Enterprise via Enterprise Map. Under human cognition behavior, the concept of operation give people the ideal of the big picture, but as soon as they got the ideal, the concept of operation become too simple and they want to know more about the whole. To drill down but without overwhelm them, EA use framework as a thinking tool of the big picture for them to think more about the big picture. Now people get the ideal, and get the scope of the big picture, they are ready to visualize the big picture in the Enterprise Map.
Without the top down process, the Enterprise Map can be overwhelming and counter production to the audience.
Concept of operation to conceptualize the whole
Framework is the tool to thank the whole.
Zachman framework is a mechanical whole based on system architecture.
Most EA methods have evolved on the Zachman framework not because of it is the best practice but because of it is an generic holistic analysis framework. The Five Ws, Five Ws and one H, or the Six Ws are questions whose answers are considered basic in information-gathering. They are often mentioned in engineering design, journalism, research and police investigation. It constitute a formula for getting the complete story on a subject. Mr. Zachman established the Zachman frame based on his observation on the generic analysis method.
Zachman framework is a generic holistic thinking tool not only for IT but also for business. It is not only for large organization but also for small organization. Enterprise Architecture is a holistic analysis approach, Zachman framework enable every one to think holistically from the aspect of what, how, who, where and when. Also from the aspect of different roles and different architecture layers. It is the foundation for the explicit EA framework of FEAF, DODAF and TOGAF. On the other hand, Solution architecture have focused on a set of requirements to provide the solution for a specific issue and it is very business process centric on “How?”.
Enterprise map was initiated in 1999 to mitigate the risk Year 2000. The enterprise map have serve well to see the whole. It is essential knows what do they have to protect from the risk of year 2000 yet most of organization only knows the parts without a artifact to see the whole. The first version of Enterprise Map is the visualization of enterprise for every one to comprehend the enterprise from the aspect of Why? What, How, Who, Where, When. It does not only describe the enterprise business but also shows how business take advantage of technology evolution via the EA layers of Application, Data and technology. This version of Enterprise Map relies on activity modeling and can be very overwhelming as shown in the following figure.
SEE THE WHOLE TO CONSTITUTE ENTERPRISE ARCHITECTURE
EA can be as simple as two posters.
Most of Enterprise Architecture approach talk and think about the whole without visualize the whole.
EA IN TWO POSTERS
EA does not have to be intimidating with complicate computer models and volumes of heavy documents. It can be as simple as two poster for all level of stakeholders. To satisfy the above principles, LEA have developed the Enterprise Map to visualize the enterprise and see the whole in an intuitive poster approach. 20% effort to deliver 80% EA value
