I get asked roughly once a quarter how to study for the TOGAF 10 certification without going through an instructor-led course. Most people asking are mid-career architects who already have a working TOGAF vocabulary and want the formal credential. The course is expensive, takes a week, and assumes a starting baseline that most practising architects are above anyway.

This post is the plan I would follow, and have followed parts of myself. It is calibrated to about 60 hours of total study time spread across 8 to 12 weeks. If you have less time you can compress; if you have more time you can deepen the Series Guides reading. The plan covers both OGEA-101 (Foundation) and OGEA-102 (Practitioner).

This is not a sponsored post. I do not run a course. I do not sell practice questions.

The starting baseline

Before you start, you should already have:

  • Five or more years of practising architect experience at any level.
  • A working vocabulary that includes “capability,” “service,” “interface contract,” and “decision record.”
  • At least passing familiarity with the existence of TOGAF, even if your last encounter with it was a previous edition.

If you do not have those things, the self-study path is harder than the course is, and I would honestly recommend the course. If you do have those things, this plan will get you through both exams.

Phase 1 — Read the TOGAF Fundamental Content (about 20 hours)

Read the TOGAF Standard, 10th Edition Fundamental Content. This is the core specification minus the Series Guides. The order I would read it in:

  1. Introduction and Core Concepts. The vocabulary. Read slowly.
  2. The Architecture Development Method (ADM). The procedural spine. Read each phase carefully. Sketch the cycle on paper without looking, more than once.
  3. The Architecture Content Framework. What each artefact is and which phase produces it. Make a one-page cheat sheet you can refer back to.
  4. The Enterprise Continuum and Tools. Read it once. Most of it is contextual rather than examinable.
  5. The Architecture Capability Framework. The governance and capability material. Important for OGEA-102, less so for OGEA-101.

Take notes as you go. I wrote about twenty pages of handwritten notes on my first read, most of which I never referred back to, but the act of writing them was what made the material stick.

Phase 2 — Read Mastering TOGAF 10 as a companion (about 20 hours)

Read Mastering TOGAF 10 alongside the standard. Do the chapter-end exercises as you go. The book is structured to roughly parallel the standard, so the back-and-forth between the two works well.

The point of the companion is not to replace the standard. It is to give you the worked examples and scenario-style questions the standard is too formal to provide. Treat the companion as the practice material for the standard’s theory material.

If you find a section of the companion repetitive, skim it. The exercises are the load-bearing part.

Phase 3 — Read the right Series Guides (about 10 hours)

The TOGAF Standard 10 splits content between the Fundamental Content and the Series Guides. For the exams, the Series Guides that matter most are:

  • Agile and the ADM. Essential. The OGEA-102 scenario questions often test whether you can apply the ADM in an iterative delivery context, and this guide is the source.
  • The Digital Enterprise. Useful. Modest exam weight, but the framing it introduces shows up in scenario questions.
  • Business Architecture: A Practitioners’ Guide. Useful. Capability mapping vocabulary comes up.
  • Information Architecture. Useful if your background is light on data architecture. Skim if not.

You do not need to read the other Series Guides for the exams. Several of them are excellent reference material for later, but they are not on the exam syllabus.

Phase 4 — Practice questions, from multiple sources (about 10 hours)

The exam style is consistent but the question selection is not. I would do practice questions from at least three sources:

  1. The Open Group’s own sample questions (free on their site).
  2. The end-of-chapter questions in Mastering TOGAF 10.
  3. At least one third-party practice exam set. There are several; most are mediocre, but doing a mediocre practice exam is still useful for calibrating timing and identifying weak areas.

For OGEA-101, the questions are mostly definitional. If you can explain what each ADM phase produces and which artefact lives where in the Content Framework, you will pass.

For OGEA-102, the questions are scenario-based. They give you a two-paragraph situation and ask which next ADM activity you should do, or which artefact you should produce. The exam style is more important than the content — once you have the rhythm, the content is the easy part.

What you can skip

You can safely skip:

  • Most of the Series Guides not listed above. Read them later if the topics come up in your work.
  • The TOGAF Library reference materials. These are useful documents but are not on the exam.
  • Online courses and bootcamps. If you are following this plan you do not need them. Save the money.
  • ArchiMate certification. ArchiMate is a separate standard. It is worth learning, but not for the TOGAF exams.

Budgeted timeline

If you have 60 hours total and want to spread them over 10 weeks, the natural split is:

  • Weeks 1–3: Phase 1 (Fundamental Content). 6–7 hours per week.
  • Weeks 4–7: Phase 2 (Companion book and exercises). 5 hours per week.
  • Weeks 8–9: Phase 3 (Series Guides). 5 hours per week.
  • Week 10: Phase 4 (practice exams). 10 hours, intensive.

Then schedule OGEA-101 the following week, and OGEA-102 two to three weeks after that.

Costs

Approximate, in USD, at time of writing:

  • TOGAF Standard 10 print edition: ~$60 from The Open Group bookstore.
  • Mastering TOGAF 10: ~$30–$50, depending on edition.
  • OGEA-101 exam: ~$320.
  • OGEA-102 exam: ~$320.

Total: roughly $750 to $800 for both certifications, exclusive of your time. This is substantially cheaper than the instructor-led courses, which typically run $2,500 to $4,000.

The hardest part

The hardest part of self-study, for most people, is the third week. Phase 1 starts well because the material is new. Phase 2 sustains because the exercises are concrete. The middle of Phase 1 is where most self-study plans die. Schedule it. Block time. Treat it as a meeting you cannot move. The standard does not get easier to read if you put it down for a fortnight.

After the exams

Once you have OGEA-102, you have the credential. The credential is useful for one or two specific things: it satisfies some procurement requirements, it removes a recruitment hurdle for certain roles, and it gives you the formal vocabulary that some TOGAF-shaped clients will expect you to use. It does not make you a better architect. The reading does.

If you want to build on the TOGAF foundation, the natural next reads are Enterprise Architecture As Strategy for the operating-model lens TOGAF assumes but does not develop, and The Software Architect Elevator for the practitioner skills the TOGAF framework is silent about.
