Views are very powerful when you want to show others your findings and to communicate with them. Therefore we invest a lot of efforts to create different types of views to reflect as many as possible angles of enterprise architecture viewpoint. We have around 60 views defined in the framework and you can decide whether you want to use all of them or only part of them. Parts of those views are hard to create and take effort to maintain (at least that is an argument that I’ve heard more then once). But, as far as I can see it, those views let you communicate efficiently with your users and they are defiantly worth the effort. You can’t use 60 views in order to articulate visually your enterprise architecture work and to preset it in front of the corporate CxOs. Therefore, we followed the idea of executive summery that you can find in any document and we create a visual enterprise architecture executive summary. As you can see below our enterprise architecture visual executive summary is a collection of 16 views.
We looked for the four most important views in each one of the enterprise architecture domains and collected them together as a visual executive summary. The business layer consists of principle and constraints view, visual concept of the enterprise, business capabilities and the main business processes modeling. The information layer consists of conceptual model of the information, enterprise logical services, security view of services usage and logical model of the enterprise information. The system (or application) layer consists from applications, enterprise services exposed by applications, security view of application usage and applications usage over enterprise locations. The technology layer consists of infrastructure view of all needed infrastructures to run the business, communication view, cost view of applications and capabilities and standards view. Natty Gur.
