The Open Group OGEA-103: Tough Topics Worth Practicing

The OGEA-103 exam combines TOGAF Enterprise Architecture Part 1 and Part 2. Part 1 is closed book and tests foundational knowledge; Part 2 is open book and uses scenario-based, gradient-scored questions that test application and analysis.

The difficult areas are where framework elements overlap: tailoring and iterating the ADM, managing requirements across phases, choosing stakeholder viewpoints, separating architecture from project management, using governance during implementation, and ranking several plausible practitioner answers. Those topics need scenario practice rather than flashcards.

ADM iteration is harder than memorizing phase order

Candidates often learn the sequence of phases but struggle to decide what should be revisited when a new requirement, merger, regulatory change, or implementation discovery appears.

Practice running the same architecture through more than one iteration. A first cycle may establish enterprise direction, while later cycles deepen data, application, technology, or migration decisions.

The method is designed to be tailored. Strong practitioner answers use the ADM purposefully instead of treating the framework as a rigid waterfall.

Practice horizontal and vertical iteration conceptually. Some iterations revisit several phases at a similar level of detail, while others deepen one domain or segment. The reason to iterate should come from scope, maturity, feedback, or changing requirements rather than from a fixed ritual.

Add a constraint that arrives during implementation and decide whether it should trigger a local exception or a broader architecture revision. This helps separate normal project variance from evidence that the target architecture itself needs to change.

Requirements management runs through everything

Requirements are identified, changed, prioritized, traced, and validated across the ADM. They are not a document created once before architecture begins.

Use one requirement such as data residency and trace how it affects business policy, data architecture, technology choices, migration, implementation governance, and later change.

When the requirement changes, identify which architecture decisions and artifacts need review. Traceability is what prevents a local change from silently invalidating the target design.

Stakeholder management is more than making a list

A stakeholder map should capture concern, influence, decision authority, and the communication view each audience needs. Executives, operations, security, finance, and delivery teams usually care about different aspects of the same architecture.

Create two views from the same architecture: one focused on business capabilities and outcomes, another on technical integration or dependencies. Both can be accurate while serving different concerns.

The practitioner skill is choosing the right viewpoint, not showing every stakeholder the largest possible diagram.

Add stakeholder conflict to the scenario. A product executive may value speed while a regulator or security stakeholder values control. The architecture process should expose the conflict and help the organization make a deliberate tradeoff rather than hiding it in technical detail.

Use power and interest to decide engagement intensity, but do not let a low-power stakeholder with critical operational knowledge disappear from the process. Influence and expertise are both relevant.

Architecture content terms are easy to blur

Deliverables, artifacts, catalogs, matrices, diagrams, views, viewpoints, and building blocks sound similar until you use them. Practice representing one architecture decision in several content forms.

Ask which item is primarily a packaged work product, which is an artifact inside it, which is a stakeholder-facing view, and which represents reusable architecture capability or solution elements.

The Part 1 exam rewards precise terminology; Part 2 rewards using that terminology to support a real decision.

Create one architecture repository example with principles, reference material, reusable building blocks, and project-specific artifacts. Explain which content should be shared broadly and which exists only for one engagement.

Use a matrix or catalog and a diagram to express the same underlying architecture in different ways. The exercise makes it easier to recognize that artifacts are representations chosen for a purpose, not interchangeable document labels.

Governance is not project management

Architecture governance checks conformance to principles, target architecture, building blocks, risk, and agreed direction. Project management controls scope, schedule, resources, procurement, communication, and delivery.

The PMP exam is a useful boundary. A project can be on time and still violate architecture direction; an architecture can be coherent while the project is poorly managed.

Practice a deviation where the project team proposes a technically different implementation. Decide whether to correct it, approve an exception, or update the architecture itself.

Add an Architecture Board or equivalent governance body to the case and define what evidence it expects from delivery teams. Governance works best when conformance criteria are known before implementation rather than invented at the final review.

Use one approved exception with an expiry or review condition. Exceptions are sometimes necessary, but they should remain visible enough that temporary deviations do not become permanent architecture by accident.

Gap analysis only matters when it drives change

A baseline-to-target comparison can produce a long list of gaps, but the useful output is the change implied by each gap. Connect gaps to work packages, dependencies, transition architectures, or migration decisions.

Prioritize gaps by business value, risk, dependency, and feasibility. Not every difference between baseline and target should become an immediate project.

This helps Part 2 because scenario answers often differ in sequence: one option identifies the gap correctly but acts on it before enough context is known.

Separate architecture gaps from implementation tasks. A gap says what capability, information, application, or technology differs between baseline and target; a work package says how the organization intends to close it.

This distinction helps migration planning because several gaps may be addressed by one work package, and one gap may require multiple initiatives over time.

Part 2 gradient scoring changes how you review answers

The Open Group’s Practitioner section awards different scores to better and worse options. Several answers can therefore contain legitimate TOGAF ideas while only one best fits the scenario.

Rank all options rather than asking whether each is true. The best answer should fit the ADM context, stakeholder concern, objective, and sequence most directly.

Avoid choosing the answer with the most framework vocabulary. Density of TOGAF terms is not the same as practitioner quality.

When reviewing practice scenarios, write why the best answer is better, not merely why the other three are wrong. A second-best option may be appropriate later in the ADM or may address only part of the stakeholder concern.

This method also exposes sequencing. Practitioner questions often reward the action that should happen now, even when another answer describes a valid technique that belongs after additional architecture work.

Open-book access can become a time trap

The electronic reference is valuable for confirmation, but it should not be the first step in every question. Form a reasoned answer from the scenario, then verify the specific point you are uncertain about.

Practice locating ADM guidance, techniques, content, governance, and relevant Series Guide material quickly. Familiarity with structure is more useful than hoping search will solve every scenario.

The OGEA-101 exam is the Foundation boundary: concepts that belong in closed-book memory should not consume Part 2 lookup time.

Practice with the actual style of electronic reference rather than relying on internet search habits. The exam reference is useful when you know where the material lives.

Create a short list of topics that belong in memory versus lookup. ADM purpose, major phase intent, core terminology, and governance concepts should be accessible without spending Part 2 time searching.

Architecture and service management can appear in the same transformation

The ITIL Foundation Version 5 exam is a useful service-management boundary. TOGAF guides enterprise architecture development and governance; ITIL guides digital product and service value, lifecycle, practices, and continual improvement.

A transformation can need both without combining them into one method. Architecture defines target capabilities, information, applications, technology, and transition direction; service management helps operate and improve the resulting products and services.

The TOGAF Enterprise Architecture Practitioner credential validates that you can apply the architecture method in context rather than merely recall its terminology.

Use one complex case as a memory anchor.

Choose a merger, cloud transformation, or digital-platform modernization that naturally involves stakeholders, requirements, baseline and target states, gaps, migration, governance, and later change.

Run the case through the ADM, then introduce one disruptive new requirement and decide which phases or artifacts need revisiting. This forces iteration, traceability, and governance into one story.

The The Open Group exam inventory can help navigate Part 1, Part 2, combined, and bridge routes. OGEA-103 readiness means both recall and best-fit architecture judgment.

Add explicit architecture principles to the case and test one proposed solution against them. If the solution violates an agreed principle, decide whether to redesign, seek an exception, or revise the principle through governance.

Finish by presenting the target architecture to two audiences using different views. The architecture remains the same, but the explanation changes to fit stakeholder concerns. That is a stronger readiness test than another round of terminology flashcards.

Add one business capability that already works well and should be preserved. Enterprise architecture is not only about replacing gaps; it is also about recognizing useful current-state strengths that should survive the transformation. This makes “start from baseline” more than a list of deficiencies.
