IntroductionIntroduction

An enterprise architecture (EA) establishes the organization-wide roadmap to achieve an organization’s mission through optimal performance of its core business processes within an efficient information technology (IT) environment. besides the choices for an EA framework at the same time choices for supporting methods and techniques has to be made.

Elements of FrameworksElements of Frameworks

3 major elements of every Framework: Construction Function Style

enterprise architecture is dealing with construction and function, without any attention of the style aspect

E2AF5

Why E2AFWhy E2AF

Every complex thing that has to operate as a whole has to be designed as a whole. This to guarantee integration and coherency of all its components and to ensure the whole will operate the way required when it is created. Organization will be fully benefits from the alignment of business and IT by integrating all enterprise architecture aspect areas into one overall result

E2AF6

What does it do for us?What does it do for us?

Enterprise Architecture results as well as E2AF itself can be used as an Atlas for management to navigate to all relevant topics. From E2AF, roadmaps can be defined to identify the necessary tasks and activities. E2AF can show the complexity of elements to be addressed. E2AF can show the people to be involved in the process. E2AF shows the relations and dependencies. E2AF is your Guide in all Architectural Activities.

E2AF Development Process (1)E2AF Development Process (1)

Enterprise Architecture environment rules & principles Business Benefits are leading Business based choices Business centric thinking instead of technology centric thinking

Business Principles are mandatory Business Scenario thinking Technology enabling by business benefits (Or Technology rationalised by business benefits)

E2AF8

E2AF Development Process (2)E2AF Development Process (2)

Translating the rules & principles into a coherent framework Separation of levels of abstraction

Separate the Strategy from Requirements Separate Requirements from solutions Separate solutions from implementations Separate implementations from transformations

Enterprise Architectures exist at different abstraction levels

E2AF9

E2AF Development Process (3)E2AF Development Process (3)

Combining aspect areas with abstraction levels Adding Viewpoints to the framework Integrating all these elements into a Framework

View & ViewPointView & ViewPoint

ViewPoint: defines the perspectives from which views are taken. From an extended enterprise perspective these viewpoints are addressing generic and common concerns covering the whole enterprise. Views: are representations of the overall enterprise architecture that are meaningful to all stakeholders in and outside the organization.

Enterprise Architectural Viewpoints Security GovernanceThe impact of viewpoints should be incorporated in

the extended enterprise architecture results at all levels.
