What is an Enterprise Architecture?

In a modern enterprise, a rigorously defined framework is necessary to be able to capture a vision of the “entire system” in all its dimensions and complexity. Enterprise Architecture (EA) is a commonly used framework which is able to coordinate the many facets that make up the fundamental essence of an enterprise. It is the master plan that, acts as an integrating force between aspects of business planning such as goals, visions, strategies and governance principles; aspects of business operations such as business terms, organization structures, processes and data; aspects of automation such as application systems and databases and the enabling technological infrastructure of the business such as computers, operating systems and networks.

However, realizing the full potential of Enterprise Architecture (EA) can be challenging. There are many aspects to EA, including architecture planning, governance, taxonomies and ontologies, all of which impact its success. Without the right guidance, tools, frameworks and methodologies EA can quickly become unwieldy. An organization can’t afford to ignore the potential benefits of well-done enterprise architecture. These benefits include decreased costs, increased revenues, improved processes, and expanded business opportunities. However an improperly planned implementation of enterprise architecture can lead to undesirable results. These include astronomical expenses, technological gridlock, and diminished executive credibility.

GYR’s Approach

Based upon the combination on extensive research, industry best practices and hands on experience of creating enterprise architecture GYR defined its own framework and approach for implementing Enterprise Architecture:

• Define Goals and Objectives of Enterprise Architecture
1. Opportunities
2. Solutions
3. Vision

• Define an Enterprise Architecture – The BITA
1. Business Architecture
2. Information Architecture
3. Technology Architecture
4. Application Architecture

• Process Mapping
1. As-Is State
2. Transition State
3. To-Be State

• Development of Plans
1. Business Process Plans
2. Functional Plans
3. Application Plans
4. Technical Plans
5. Migration Planning

• Implement Governance
• Architecture Change management
• Monitor
