There are many Enterprise Architecture (EA) frameworks, each with different levels of rigor, focus, and scope. Understanding their differences is crucial for selecting the right framework for an organization's needs.
Enterprise Architecture Frameworks
The most commonly used EA frameworks include:
- Zachman Enterprise Framework
- TOGAF (The Open Group Architecture Framework)
- DoDAF (Department of Defense Architecture Framework)
- Gartner Enterprise Architecture Framework
- E2AF (Extended Enterprise Architecture Framework)
- IAF (Capgemini’s Integrated Architecture Framework)
- PEAF (Pragmatic Enterprise Architecture Framework)
- FEAF (U.S. Federal Enterprise Architecture Framework)
- TEAF (Treasury Enterprise Architecture Framework)
Key Differences Among EA Frameworks
- Evolution Path – Frameworks have evolved differently, shaped by specific industry needs.
- Scope – Each framework focuses on different areas, such as business, IT, security, or governance.
- Principles – The guiding principles and methodologies vary across frameworks.
- Purpose – Some frameworks focus on strategy, while others are more operational or technical.
- Structure – Each framework organizes architectural elements differently.
Comparison Criteria for EA Frameworks
Organizations can compare EA frameworks based on the following key criteria. The relevance of each criterion may vary based on organizational needs.
- Coverage – How comprehensively the framework addresses different aspects of enterprise architecture.
- Detail/Completeness – The level of detail provided for implementation.
- Adoption in the Industry – The framework's popularity and usage across enterprises.
- Business Focus – The emphasis on aligning IT with business objectives.
- Governance Model – The framework’s approach to oversight, compliance, and decision-making.
- Vendor Neutrality – Independence from specific vendors or technologies.
- Availability of Information & Resources – Documentation, training, and community support.
- Implementation Time – The effort required to adopt and integrate the framework.
- Effectiveness Assessment – The ability to measure success and continuous improvement.
- Tools, Templates, and Reference Models – Availability of supporting materials for easier adoption.
Scoring EA Frameworks
Organizations can assign scores on a scale of 1 to 5 for each criterion to compare frameworks:
- 5 – Excellent
- 4 – Very Good
- 3 – Good
- 2 – Poor
- 1 – Very Poor / No Support
By applying weighted scores based on organizational priorities, businesses can select the most suitable EA framework.
Each organization should carefully evaluate these frameworks based on its specific goals, maturity level, and operational model. Selecting the right framework can enhance strategic alignment, governance, and enterprise-wide efficiency.

Explanation of Scores
- TOGAF is the most widely used and detailed framework with strong governance, methodology, and tool support.
- Zachman is more of a classification framework and lacks detailed implementation guidance.
- DoDAF and FEAF are government-focused, offering strong governance and documentation but limited industry adoption.
- Gartner EA Framework is business-oriented and strategic but less detailed on implementation.
- PEAF is a simplified EA framework, making it easier to implement but lacking in coverage and governance.
- IAF, E2AF, and TEAF have moderate coverage but are less commonly adopted in industries.
