Do you need to design or improve an enterprise architecture? If so, you’ll need to learn about enterprise architecture frameworks.
This blog will explore the enterprise architecture framework, its domains, types, and benefits. It will also provide its methodologies and how to use them to improve your business.
What is an Enterprise Architecture Framework?
An enterprise architecture framework is a set of guidelines and rules that help you design, plan, and manage your enterprise IT systems. There are many different enterprise architecture frameworks, but they all share standard features and benefits.
The below image shows the holistic view of an enterprise architecture framework.
Enterprise Architecture Domains
Four main domains are
- Business Architecture
- Data or information Architecture
- Application Architecture
- Technology Architecture
1. Business Architecture
Business Architecture is the topmost layer of the EA framework. It defines the overall goals and objectives of the enterprise.
For example, a retail company aims to enhance its market share by 15% over the next year. The company’s enterprise architect should first work on the goal by analyzing the contributing factors of the business’s present market share.
So after analyzing it, he can identify the changes that need to be done to increase the market share.
This domain also describes the present capabilities of the business and the roles and responsibilities of each department in the organization.
2. Application Architecture
The application layer builds upon the business layer and provides specific functionality to support the business objectives.
Enterprises now use various applications across departments, such as project management, product management, customer management, supplier management, etc. The enterprise architects of this domain find out how to deploy and interconnect these applications.
Sometimes managers or employees want to add some more applications, that time, and the enterprise architect should analyze the benefits of the tool, document the use of the application, and find out how it is integrated with other tools. He can also make policies for the usage of applications.
3. Data/Information Architecture
The data layer stores and manages all of the data used by the applications in the application layer.
This domain helps to describe and document the organization’s logical and physical assets and resources. It also guides people in using and transforming the information according to their needs.
The data includes transaction data, metadata, reference data and master data, and more. The architect classifies and decides which data is needed for which department.
For example, if a company extends its business to another country, the enterprise architects make a data management plan for the extended business. The plan may include setting up a new data process, complying with data regulations, etc.
This domain is very important because data collected, stored, and excited by the company affect the business decisions and customer experience. Hence the architect should ensure that the data is accurate, secure, available, and accessible.
4. Technology Architecture
The technology layer provides the infrastructure and platform for the other three layers. It includes hardware, operating systems, middleware, back-end infrastructure, and networking.
This domain’s architect must determine the hardware and software infrastructure requirements to enhance the resources in the other three domains.
Types of Enterprise Architecture
Enterprise Architecture Frameworks
EA frameworks are the most popular type because they provide a comprehensive approach to enterprise architecture and include guidelines for all aspects of enterprise IT systems.
These are usually based on the Zachman or TOGAF frameworks.
Enterprise Architecture Methodologies
EA methodologies are less popular than EA frameworks but offer some unique benefits.
They focus on the enterprise architecture process rather than the enterprise architecture itself. That can improve your enterprise IT systems over time.
Technology Architecture Frameworks
Technology architecture frameworks are similar to enterprise architecture methodologies in that they focus on a specific part of enterprise IT systems rather than the whole system.
Technology architecture frameworks address technical issues such as storage, networking, and security. They can be helpful for organizations that want to focus on specific technology issues.
Types of Enterprise Architecture Frameworks
There are many different methodologies, but they can be broadly classified into five categories:
1. Zachman Framework
The Zachman Framework (ZF) is one of the most famous EA frameworks. It was created by John Zachman in 1987 and provides a structure for describing an enterprise’s information systems. It covered all aspects of enterprise IT systems and was named a template framework.
Zachman Framework features include
- Defines enterprise IT systems at six different levels: business, application, data, technology, security, and integration
- Provides a standard way to describe an enterprise’s information systems
- Focuses on the relationships between the different parts of an enterprise IT system
- It can be used to develop enterprise IT systems from scratch or to improve existing systems
2. The Open Group Architecture Framework (TOGAF)
The open group architectural framework (TOGAF) is a famous enterprise architecture framework used by many large organizations. It was created in 1995 by The Open Group, a consortium of IT companies, and is based on the Zachman Framework. TOGAF is considered to be the most comprehensive EA framework.
TOGAF features include
- A detailed and iterative approach to enterprise architecture development
- A clear definition of enterprise architecture components and their relationships
- A well-defined enterprise architecture development process
- A comprehensive set of tools and techniques for enterprise architecture development
- A rich body of knowledge consisting of best practices, guidelines, and case studies
3. DoDAF
The Department of Defense Architecture Framework (DoDAF) is specifically designed for military enterprise IT systems.
DoDAF Features include
- Provides a standard way of representing architectures so that stakeholders can easily understand complex enterprise systems
- Decomposes enterprise systems into manageable pieces for analysis
- Identifies gaps and redundancies in enterprise systems
- Provides a common language for architects and engineers to communicate about enterprise systems
4. MODAF
MODAF is a UK government-developed enterprise architecture framework. It was created in 2002 and has been updated several times since. MODAF is used by UK government organizations and companies doing business with the UK government.
MODAF features include:
- A focus on enterprise architectures for defense and security
- A clear definition of enterprise architecture concepts and their relationships
- A well-defined enterprise architecture development process
- A comprehensive set of tools and techniques for enterprise architecture development
- A rich body of knowledge consisting of best practices, guidelines, and case studies
5. FEAF
The Federal Enterprise Architecture Framework (FEAF) is a framework specifically for designing enterprise IT systems for the federal government.
U.S. Federal Government develops this framework in the year 2006.
It is the combination of both the Zachman framework and ToGAF. It has five reference models and five points, including business, components, service, data, and technical.
6. Others
Many other enterprise architecture frameworks are available, including ones specific to healthcare, banking, and manufacturing.
UPDM
Object management group (OMG) developed UPDM. It is the Unified Profile for the UK Ministry of Defence Framework (MODAF), USA Department of Defence Architecture Framework (DoDAF), and NATO Architecture Framework (NAF). Its latest version is UPDM 2.1.1.
NAF 4.0
This architecture is developed to serve many organizations, including NATO and other national defense agencies. It provides the standard for both military and business.
- It lines up with architectural references produced by international standard bodies.
- It provides rules, guidelines, and descriptions for developing describing architectures.
- It provides a 2-dimensional classification scheme for the standardized architectural viewpoints.
Open agile architecture (O-AA)
It is a standard developed by The Open group for all business stakeholders and work teams who work on both agile and digital transformation.
For example,
- Enterprise architects – Helps to expand their scope of influence in Agile
- Business leaders – Helps to do digital and agile change.
- Product managers – Helps to modify customer experience, innovate products, and increase efficiency.
- Product owners – Helps to manage feature backlog.
- Software engineers – Helps to hold the power of digital technologies to co-innovate with the business.
- Operation managers

FAQ
How is enterprise architecture methodology different from enterprise framework?
Enterprise architecture methodologies differ from enterprise frameworks in that they focus on the process of enterprise architecture rather than the enterprise itself.
Enterprise frameworks provide guidelines for all aspects of enterprise IT systems, while enterprise architecture methodologies focus on specific aspects.
For example, TOGAF is a famous enterprise framework, while the Zachman Framework is a famous enterprise architecture methodology.
Conclusion
Enterprise architecture frameworks provide a structure for describing an enterprise’s information systems.
There are many different enterprise architecture frameworks, but they can be broadly classified into six categories: Zachman Framework, TOGAF, DoDAF, FEAF, Gartner, and Others. There are many benefits of using an EA framework.
