Introduction Frameworks Overview Comparison Table Best Practices FAQ

Introduction

This lesson provides a detailed comparison of four prominent Enterprise Architecture (EA) frameworks: TOGAF, Zachman, FEAF, and DoDAF. Understanding these frameworks is crucial for organizations aiming to align their IT infrastructure with their business goals.

Frameworks Overview

1. TOGAF

TOGAF (The Open Group Architecture Framework) is a comprehensive framework designed to assist in the development and management of enterprise architecture. It emphasizes a structured approach to organizing and analyzing the components of enterprise architecture.

2. Zachman Framework

The Zachman Framework provides a structured way of viewing and defining an enterprise. It is a classification schema that helps in the organization of the various aspects of an organization’s architecture.

3. FEAF

The Federal Enterprise Architecture Framework (FEAF) is a framework developed for federal agencies to ensure that their investments in IT support their missions. It provides a common approach for IT architecture across the federal government.

4. DoDAF

The Department of Defense Architecture Framework (DoDAF) is used within the Department of Defense for developing architectures. It focuses on the integration of various defense operations and systems.

Framework	Purpose	Key Components	Best For
TOGAF	Enterprise architecture development	Architecture Development Method (ADM)	Any enterprise
Zachman	Classification of enterprise artifacts	Six perspectives on architecture	Complex organizations
FEAF	IT investments alignment	Performance reference model	Federal agencies
DoDAF	Integration of defense systems	Views and models	Defense organizations

Best Practices

When implementing any of these frameworks, consider the following best practices:

Ensure clear communication across stakeholders.
Adapt the framework to fit the organization's unique needs.
Regularly review and update the architecture.
Train staff on the framework to ensure compliance and understanding.
