The Open Group released the 10th Edition of the TOGAF standard in April 2022. This update modularized the framework, separating universal core concepts from domain-specific guides like agile development and security architecture. Today, the organization reports over 120,000 certified professionals worldwide. Employers spanning government agencies, defense contractors, and Fortune 500 companies treat TOGAF as the baseline methodology for enterprise architecture roles.
The TOGAF Certification Structure
The Open Group organizes its knowledge-based credentials into a straightforward, two-tier model: Foundation (Part 1) and Practitioner or Certified (Part 2). Foundation exams test your recall of terminology and basic concepts. Part 2 exams test your ability to apply the framework to practical scenarios.
Candidates can take these exams separately or together.
For the current 10th Edition standard, you might start with the OGEA-101 (TOGAF Enterprise Architecture Part 1) to secure your Foundation credential. Many candidates bypass the sequential route and take the OGEA-103 (TOGAF Enterprise Architecture Combined Part 1 and Part 2). This combined exam grants the full Practitioner certification in a single sitting.
If you fail one section of a combined exam, you only need to retake the failed portion after a one-month waiting period.
The platform also lists specialized credentials like the OGBA-101 (TOGAF Business Architecture Foundation). This exam narrows the focus, targeting professionals who need to model business capabilities, value streams, and organizational mapping without diving into the technical data and application layers.
Inside the Exams: Part 1 vs. Part 2
The Open Group exams follow a distinct format that separates theoretical knowledge from applied decision-making.
The Part 1 section is a closed-book test. You have 60 minutes to answer 40 simple multiple-choice questions. These questions focus on definitions, the phases of the ADM, and the purpose of specific architecture deliverables. You earn one point for each correct answer and need 24 points to pass.
The Part 2 section shifts the format entirely.
This is an open-book test where candidates have access to an electronic copy of the TOGAF Body of Knowledge. You have 90 minutes to answer eight complex, scenario-based questions.
Part 2 questions use a gradient scoring system. Each question presents a detailed business scenario and asks you to choose the best architectural approach. The most correct answer earns five points. The second-best answer earns three points. The third-best earns one point, and the worst answer earns zero. You need 24 points out of a possible 40 to pass this section.
This scoring model reflects the reality of enterprise architecture. There is rarely one perfect answer to a business problem. Instead, there are approaches with varying degrees of risk and alignment with the framework.
Beyond TOGAF: ArchiMate and IT4IT
While TOGAF defines the method for developing architecture, it does not mandate a specific notation for drawing it. That is where ArchiMate comes in.
ArchiMate is an open, independent modeling language for enterprise architecture. It provides a uniform representation for describing, analyzing, and visualizing relationships among business domains. Where TOGAF tells you what steps to take, ArchiMate gives you the visual grammar to map out the results.
You can take the OGA-031 (ArchiMate 3 Part 1) to prove your foundational knowledge of the language's core concepts, structural elements, and relationships. Architects use this notation to build clear, standardized diagrams that stakeholders across different departments can read and understand.
The Open Group also maintains the IT4IT Reference Architecture. Unlike TOGAF, which focuses on mapping IT to the broader business, IT4IT focuses specifically on the business of IT. It provides a value-chain approach to managing the IT function itself, tracking the lifecycle of digital products from strategy to operations.
The OG0-061 (IT4IT Part 1 Exam) tests your understanding of this reference architecture. It covers the core value streams, including Strategy to Portfolio, Requirement to Deploy, Request to Fulfill, and Detect to Correct. Organizations adopting product-centric IT operating models often require this credential for their IT management teams to ensure everyone follows the same service delivery lifecycle.
Market Position and Practical Value
Enterprise architecture is a senior discipline. You do not start your career as an enterprise architect. You transition into the role after years spent managing networks, writing software, or administering databases.
Because of this, Open Group certifications serve a specific purpose. They do not teach you how to configure a router or deploy a cloud server. They teach you how to communicate technical decisions to business executives. They provide a shared vocabulary. When a TOGAF-certified architect mentions "Phase B" or an "Architecture Vision," other certified professionals in the room know exactly what deliverables to expect.
A common criticism of TOGAF is its sheer size. The framework can feel heavy and academic. The 10th Edition update directly addressed this by moving rigid, prescriptive elements into separate, optional guides. But the exams still require you to memorize a massive volume of structural concepts.
If you want to move from engineering into strategic planning, The Open Group exams provide the clearest path. The OGEA-103 acts as a filtering mechanism for hiring managers. It proves you understand how to link IT investments to business outcomes, rather than just solving isolated technical problems.
