Introduction

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.

E2AF 4

Elements 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

E2AF 5

Why 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

E2AF 6

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 7

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)

E2AF 8

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

E2AF 9

E2AF Development Process (3)

Combining aspect areas with abstraction

levels

Adding Viewpoints to the framework

Integrating all these elements into a

Framework

E2AF 10

E2AF Full Blown

E2AF 11

Separation of concerns

Contextual (Why?)

Environmental (With Who?)

Conceptual (What?)

Logical (How?)

Physical (With what?)

Transformational (When?)

E2AF 12

Decomposition of the Enterprise

Business

Information

Information Systems

Technology Infrastructure

E2AF 13

View & 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

Governance

The impact of viewpoints should be incorporated in the extended enterprise architecture results at all levels.

when is an Enterprise

Architecture Good Enough ?

“An Enterprise Architect knows he has achieved

the perfect solution not when there is nothing left to

add, but when there is, nothing left to take away.”

Tool Selection (1)

tools basic functionality:

Methodologies and Models;

Model Development Interface;

Tool Automation;

Extendibility and Customization;

Analysis and Manipulation;

Repository;

Deployment Architecture;

Costs and Vendor Support.

E2AF 22

Tool Selection (2)

tool’s utility to different professionals:

Enterprise Architects;

Strategic Planners;

Enterprise Program Managers.

E2AF 23

Tool Selection (3)

The purpose of adopting an EA Tool:

Supporting decision making of management

requires another level of detail in models and

diagrams then supporting application

development.
