Enterprise Architecture

Somebody on every large transformation has to make the plan hold together - the stakeholder nobody consulted, the data that cannot move yet, the sequence that costs half as much in a different order. That is the TOGAF Enterprise Architecture Practitioner's job, and OGEA-102 is where you prove you can do it: eight scenario questions, 90 minutes, open book, 60% to pass.

It is also the whole difference between the two TOGAF levels. Part 1 checks that you know what the TOGAF Standard says. Part 2, examined as OGEA-102, checks that you can pick the right move when a scenario gives you a half-finished programme, an unhappy sponsor and four plausible things to do next.

This guide walks through what practitioners are expected to do, how The Open Group builds the Part 2 exam around that work, what the syllabus covers phase by phase, and how to get ready without reading the entire standard cover to cover.

What does a TOGAF Enterprise Architecture Practitioner actually do?

Strip away the vocabulary and the role comes down to one job: keep a large change programme coherent. Someone has to decide which business capabilities the transformation touches, which data has to move, which applications are retired and which technology the target state needs. Someone has to show the finance director why the sequence costs less in that order, and show the delivery teams what they are allowed to change. That is the practitioner's work, and the Architecture Development Method is the routine that keeps it repeatable across programmes.

The OGEA-10B exam is the fastest route from TOGAF 9 Certified to TOGAF Enterprise Architecture Practitioner. It has 14 questions in 60 minutes, costs USD $385 and needs 60% to pass. A good TOGAF 10 study guide for it covers what changed in the 10th Edition, the ADM phases in practice, and open-book scenario technique.

If you earned TOGAF 9 Certified, you already know the Architecture Development Method, the content framework and the vocabulary of enterprise architecture. The Open Group recognises that investment with a bridge: instead of sitting the full Foundation and Practitioner exams again, you take one shorter exam that checks whether you can apply the TOGAF Standard, 10th Edition, to real architecture work.

This study guide explains what the bridge exam covers, how its two sections work, how hard it is, and how to prepare in about three weeks. It is written for enterprise architects, solution architects and architecture leads who hold TOGAF 9 Certified and want the current Practitioner credential without wasting time on material the exam does not test.

OG0-093 packs both TOGAF 9 levels into one 150-minute sitting: 40 closed-book questions, then eight open-book scenarios. Clear 55% on the first section and 60% on the second and you leave the test centre TOGAF 9 Certified after a single appointment. Miss one section and you resit that section alone. Preparing for this paper is therefore two jobs stitched together, not one long revision push.

The stitching is what catches people out. The two halves reward opposite habits. One wants fast, unaided recall of vocabulary and method. The other wants unhurried judgement with the standard open on screen. There is no break between them, and once the first half closes you cannot go back to it. What follows is the format, the money, the syllabus in the order worth learning it, a six-week plan, and the pacing that decides how the final forty minutes go.

How is the OG0-093 exam built, and what does it cost?

OG0-093 is The Open Group's combined paper for candidates who want Level 1 and Level 2 recognition from one appointment. Section 1 reproduces the TOGAF 9 Part 1 paper: forty straightforward multiple-choice items, closed book, one point apiece. Section 2 reproduces the Part 2 paper: eight scenario questions marked on a sliding scale, with an electronic copy of the standard available inside the exam window. Both sections run inside a single 150-minute clock, divided sixty minutes and ninety minutes, and the section boundary is one-way.
