What is an enterprise architecture framework?

Enterprise architecture frameworks are the backbone of the EA discipline, offering a systematic approach to organizing the structure and operation of an organization.

They can be thought of as a blueprint for methodically capturing the key views of an enterprise. In other words, they are conceptual tools that assist organizations in understanding and documenting their internal structures, IT assets, processes, and policies.

These frameworks assist organizations in planning and implementing enterprise-wide analysis to ensure that IT and business alignments meet the strategic objectives.

They typically include:

  • A set of principles and practices that guide the enterprise architecture process.
  • A common vocabulary and set of models that ensure consistent and unambiguous communication.
  • A methodological approach to organizing the system architecture of an organization.

Frameworks often differ in their scope and may target different levels of enterprise architecture, such as business, data, application, and technology architecture.

Some frameworks are more prescriptive, while others are descriptive; some focus on the process, others on documentation.

The importance of standardization in EA frameworks

Standardization within EA frameworks is crucial because it ensures that the various elements of an organization's architecture are consistent and integrated.

It helps to avoid duplication of effort and reduces the potential for conflict between IT systems and business processes.

Standardized frameworks also facilitate:

  • Better collaboration between IT and business units.
  • Improved decision-making due to the clear and structured representation of information.
  • Increased efficiency in managing IT assets and resources.
  • Easier adoption of new technologies and processes as the enterprise evolves.
  • Moreover, standardization helps in benchmarking and evaluating the effectiveness of the EA efforts against industry standards. It enables organizations to measure their progress and maturity, identify areas of improvement, and implement best practices.

Enterprise architecture frameworks list

Enterprise architecture frameworks are not one-size-fits-all; they vary greatly in their approach, methodology, and end goals.

This section provides a high-level overview of what these frameworks are and the significance of standardization within them.

1. The Open Group Architecture Framework (TOGAF)

TOGAF is one of the most popular and widely used enterprise architecture frameworks. Developed by The Open Group, this framework is designed to help organizations design, evaluate, and build the right architecture for their organization.

Core concepts

The framework is centered around the TOGAF Architecture Development Method (ADM), which provides a step-by-step approach to developing an enterprise architecture. The ADM addresses all the necessary phases, from the initial planning, through to the management and governance of the architecture once it's in place.

TOGAF's Architecture Development Method (ADM)

The ADM cycle consists of the following phases:

  • Preliminary Phase: Prepare the organization for adopting TOGAF.
  • Phase A: Architecture Vision: Define the scope, stakeholders, and vision.
  • Phase B: Business Architecture: Develop the business architecture.
  • Phase C: Information Systems Architectures, which includes data and application architecture.
  • Phase D: Technology Architecture: Design the technology architecture.
  • Phase E: Opportunities and Solutions: Identify delivery vehicles for the architecture defined.
  • Phase F: Migration Planning: Develop a detailed implementation plan.
  • Phase G: Implementation Governance: Oversee the implementation.
  • Phase H: Architecture Change Management: Manage changes to the new architecture.

Supporting these phases are the TOGAF Enterprise Continuum & Tools, which provide a way to classify and store the various assets involved in EA.


  • Provides a comprehensive approach to design, planning, implementation, and governance of an enterprise information architecture.
  • Is adaptable to an organization’s needs.
  • Offers detailed guidance on the process of building IT architectures.

2. Zachman Framework

The Zachman Framework is one of the earliest and most fundamental enterprise architecture frameworks. It was created by John Zachman in 1987 and has been a cornerstone in the field of enterprise architecture for its comprehensive and descriptive focus.

It is often described as a taxonomy for organizing architectural artifacts (in other words, design documents, specifications, and models) that come into play when creating complex enterprise systems. Unlike some other frameworks that are process-oriented, the Zachman Framework is structured as a matrix.

The structure

The framework consists of a two-dimensional classification schema that reflects the intersection of six communication questions (What, How, Where, Who, When, Why) with six rows representing different perspectives (Planner, Owner, Designer, Builder, Subcontractor, and Enterprise Operations).

Key components and artifacts

Each cell in the matrix represents a specific artifact required for creating a complete picture of the enterprise architecture. These artifacts help in understanding and documenting the enterprise from different perspectives, ensuring that nothing is overlooked.


  • Provides a highly structured way of viewing and documenting an enterprise from a holistic point of view.
  • Each perspective is clearly defined, which can aid in thorough documentation and analysis.
  • Helps in ensuring that all stakeholder concerns are addressed.


  • The framework can be seen as overly complex and rigid.
  • It does not provide a specific method for creating an enterprise architecture.
  • It may be difficult to apply in fast-paced environments where agility is required.

📚 Related: Zachman Framework Detailed Guide

The Zachman Framework has significantly influenced the development of later EA frameworks, which often incorporate some of its key concepts and structures.

3. Federal Enterprise Architecture Framework (FEAF)

FEAF is an enterprise architecture framework developed by the United States Federal Government to provide a common approach for the integration of strategic, business, and technology management as part of organization-wide improvement efforts.

FEAF promotes shared development for federal processes, interoperability, and sharing of information among federal agencies and other government entities. By using FEAF, federal agencies can better align their IT resources with their missions and strategic plans, which in turn helps to serve the public more effectively.

FEAF's segmentation architecture

One of the key components of FEAF is its Segmentation Architecture, which divides the enterprise into manageable segments (or business areas) that can be addressed independently while maintaining a holistic view of the enterprise. This allows for targeted improvements and easier management of IT investments.

FEAF's Performance Reference Model (PRM)

The PRM is another integral part of FEAF, which helps to measure the performance of IT investments and their impact on strategic outcomes. It provides a common framework for understanding performance across federal agencies, enabling better decision-making and more effective management of federal IT resources.

Implementing FEAF in government organizations

Implementing FEAF can bring about significant benefits, including:

  • Enhanced alignment between business and IT.
  • Improved decision-making through a common taxonomy and methodology.
  • Increased collaboration and sharing across federal agencies.

However, organizations may face challenges such as:

  • Adjusting to a standardized way of documenting and analyzing their architecture.
  • The need for significant cultural and organizational change management.
  • Ensuring consistency and compliance across different segments of the enterprise.

In summary, FEAF provides a structured approach for federal agencies to manage their enterprise architecture. It is tailored to meet the unique needs of the federal government, facilitating better service delivery and governance.

4. ArchiMate: A Modeling Language for EA

ArchiMate, developed by The Open Group, is a comprehensive enterprise data modeling language that allows IT architects to create clear and integrated models of enterprise architecture. It is distinct from other enterprise architecture frameworks but is often used in conjunction with them, like TOGAF, to enhance the visualization of architecture.

ArchiMate provides a uniform representation for diagrams that describe enterprise architectures. It offers an integrated architectural approach that describes and visualizes the different architecture domains and their underlying relations and dependencies.

ArchiMate's Layered Approach

The language is structured around three main layers:

  • Business layer: which offers products and services to external customers, which are realized in the organization by business processes performed by business actors.
  • Application layer: which supports the business layer with application services that are realized by (software) applications.
  • Technology layer: which offers infrastructural services needed to run applications, realized by computer and communication hardware and system software.

These layers are supported by additional aspects such as motivation and strategy, which help in aligning the architecture with the business goals.

Integrating ArchiMate with other EA frameworks

ArchiMate is designed to coexist with other EA frameworks. For instance, TOGAF's ADM can be used to manage the development lifecycle of an enterprise architecture, while ArchiMate can be used to describe and visualize the various phases and components within that lifecycle.

Use cases and application of ArchiMate:

ArchiMate is used by organizations to:

  • Describe the structure and operation of business processes, organizational structures, information flows, IT systems, and technical infrastructure.
  • Bring clarity to complex architecture descriptions to aid in better understanding and communication.
  • Support analysis and decision-making with visual representations of enterprise architecture concepts.

What is enterprise architecture (EA)?

Enterprise architecture is a strategic framework that aligns an organization's business strategy, processes, information, and technology to achieve its goals. It provides a holistic view of the organization, enabling effective decision-making, optimization of resources, and adaptation to changes in the business environment.

How do enterprise architecture frameworks differ?

EA frameworks vary in complexity, scope, and methodology, tailored to different organizational sizes, industries, and strategic goals. 

Why is an enterprise architecture framework important for an organization?

An EA framework provides a structured approach for aligning IT investments with business goals, leading to improved efficiency and strategic agility. 

How does an organization select an EA framework?

Most Enterprise Architects will already be familiar with the TOGAF framework due to its popularity in the practice, but FEAF contains guidance analogous that accompany TOGAF’s Foundation Architecture, viewpoints, and views. While the FEAF is oriented toward enterprise architecture, TOGAF is more oriented toward IT architecture. This means there are benefits of having insights into both frameworks and methodologies.

The key difference between TOGAF vs FEAF is that the FEAF is designed to provide guidance to federal agencies for structuring their enterprise architecture. The way the FEAF matrix is structured also does not directly map to the TOGAF structure but corresponds more to the Zachman Framework. That said, three of the four architecture domains covered by TOGAF also correspond directly to the columns of the FEAF matrix (see above).

What impact do EA frameworks have on digital transformation?

EA frameworks guide digital transformation by providing a structured approach to integrating new technologies with business processes and models.
