What is Enterprise Architecture?
A brief introduction to enterprise architecture
Enterprise architecture is a comprehensive, strategic discipline aimed to give structure to an enterprise, or organization. A good enterprise architecture creates a sustainable organization that is able to achieve its current business objectives.

An Overview of Enterprise Architecture and its Importance within Business & IT
Enterprise Architecture (EA) is a rigorous approach for describing the structure of an enterprise. A well-managed enterprise architecture results in an effective and sustainable enterprise.
It can be regarded as three things:
- A Discipline. It is the way of thinking about the structure of an enterprise.
- A Process. There are processes for architecting an enterprise, covering how architectures are created, how they change and evolve, and how architectures are managed.
- A set of work products. A set of models and diagrams that represent and describe the structure of an enterprise.
Developing and sustaining an enterprise architecture is a complex process, involving many stakeholders and decision processes. TOGAF is a popular enterprise architecture framework. TOGAF helps by documenting the Enterprise Architecture discipline, process and work products.
By using a standard framework, organizations can develop an enterprise architecture that is consistent, reflects the needs of stakeholders, employs best practice, and gives due consideration to current requirements.
