OG0-023 ArchiMate 2 Combined: Legacy Exam and the Current ArchiMate Path

OG0-023 was The Open Group’s combined ArchiMate 2 Part 1 and Part 2 examination. It is a legacy exam: The Open Group’s examination-fee history records the ArchiMate 2 exams as no longer available from August 2022. The historical combined session contained 48 items across two sections and allowed 150 minutes in total. Candidates searching this code today should therefore use it to understand an older credential record or older study material, not as a current booking target.

The current ArchiMate program is ArchiMate 3, aligned in current Open Group support material with the ArchiMate Specification, Version 3.2. It uses separate OGA-031 Part 1 and OGA-032 Part 2 exams; current guidance explicitly says there is no combined Part 1 and Part 2 exam for ArchiMate 3. The distinction matters because simply replacing the old version number in an OG0-023 study plan would create the wrong exam strategy.

A useful legacy page should preserve what OG0-023 represented while guiding current learners toward the live route. The durable subject is architecture modeling: elements, relationships, viewpoints, layers, motivation, strategy, implementation, and the ability to interpret or create coherent models. The exam mechanics and specification generation are the parts that changed.

The historical combined exam joined knowledge and application in one sitting

OG0-023 combined the ArchiMate 2 Foundation and Certified assessments. Part 1 used 40 simple multiple-choice questions and required at least 60 percent. Part 2 used eight complex scenario questions with gradient scoring, was open book, and required at least 70 percent. Both sections had to be passed for the combined result to confer the higher qualification. That structure explains why old preparation material often alternates between terminology drills and scenario interpretation.

Part 1 and Part 2 also demanded different study behavior. The Foundation section rewarded quick recognition of notation and concepts, while the Certified section required interpretation of a situation and selection of the best modeling response. That distinction survives in the current Foundation and Practitioner levels even though the old combined delivery disappeared. Candidates converting older notes should therefore separate “language facts” from “applied modeling judgment” instead of treating every flashcard as equally useful.

The modern program retains the same broad progression from foundation knowledge to practical application, but the current specification and exam route are different. Treating historical scores, terminology, or sample questions as a complete preparation source would ignore years of language development.

ArchiMate is a modeling language, not an enterprise-architecture method

One of the most important conceptual distinctions is between the language and the process that uses it. ArchiMate provides concepts and relationships for representing architecture; it does not prescribe a full architecture-development lifecycle. The Open Group also maintains The Open Group certifications around TOGAF, and the two bodies of knowledge can complement each other: a method can structure architecture work while ArchiMate supplies a consistent visual language for expressing results.

That distinction helps prevent common modeling mistakes. A candidate should ask what the model needs to communicate, which concepts represent that meaning, and which relationships are valid—not assume that drawing a diagram automatically demonstrates a sound architecture process.

Layered modeling connects business, application, and technology concerns

ArchiMate’s value comes from showing how different architectural concerns relate. Business behavior can be supported by application services; applications depend on technology services and infrastructure; strategy and motivation can explain why a change is being pursued; implementation and migration concepts can represent the transition. Preparation should therefore include tracing dependencies across layers rather than memorizing each element in isolation.

Add motivation and migration to the same exercise. Explain why the organization wants the change, identify the desired outcome, show the business behavior affected, trace the enabling applications and technology, and then represent the work needed to reach the target. This creates a small architecture story. It is more educational than memorizing each layer separately because it demonstrates how the language can connect strategy, structure, behavior, and transformation.

A strong exercise starts with a business outcome and follows the chain down to enabling systems and technology, then reverses the direction to ask what business consequences follow if a technical dependency changes. That makes the notation meaningful and prepares the learner for questions that test relationships rather than labels.

Relationships are where superficial memorization usually fails

Many incorrect ArchiMate models contain plausible elements joined by the wrong relationship. Candidates should understand the semantic difference between structural, dependency, dynamic, and other relationship families and recognize how direction changes meaning. Do not learn relationships only as icons or arrowheads. Explain in words what one element is asserting about another, then confirm that the notation expresses that assertion.

Relationship practice should also include derived relationships and the consequences of abstraction, but only at the level supported by the current specification you are studying. The important habit is semantic checking: if a relationship is inferred through a chain of model elements, confirm that the derived meaning is actually allowed. Old ArchiMate 2 examples are especially risky here because candidates may remember a valid historical pattern that no longer matches the current specification guidance.

This discipline becomes especially important in scenario questions because several diagrams may look visually reasonable. The best answer is the one that preserves the intended semantics with the least distortion, not the one with the most objects.

Viewpoints should be selected for stakeholder purpose

A model is not valuable merely because it is complete. Different stakeholders need different slices of architecture, and a viewpoint controls what is emphasized. Practice by taking the same underlying architecture and producing views for an executive, process owner, application architect, and infrastructure team. Each audience asks a different question, so the useful elements and level of detail change.

This also explains why massive all-in-one diagrams are poor study artifacts. They encourage visual recognition without teaching communication. Smaller purposeful views force the learner to decide what information matters.

Current candidates should study the ArchiMate 3.2 language directly

The current ArchiMate 3 Foundation exam validates the notation, terminology, structure, and core concepts of the modern language. The ArchiMate 3 Practitioner exam adds applied modeling and scenario reasoning. Current Open Group support material identifies the 3.2 specification as the reference for the program, so candidates should build study notes around that version rather than retrofit ArchiMate 2 diagrams.

The 3.2 maintenance level did not turn ArchiMate into an entirely different language, which is why some older conceptual explanations still feel familiar. The danger is precisely that familiarity: a learner may not notice which details changed. Use older material for intuition only after building a current reference map from the 3.2 specification. Current terminology should always win when a conflict appears.

If an older OG0-023 book explains a general modeling idea well, it can still be useful as background. Every exam-specific statement—element definitions, relationship rules, viewpoints, examples, and test logistics—should be checked against current 3.2 material.

The current route separates Foundation and Practitioner exams

OGA-031 is a 40-question, 60-minute closed-book Part 1 exam with a 60 percent pass requirement. OGA-032 is an eight-question, 90-minute open-book scenario exam with gradient scoring and a 65 percent pass requirement. Candidates normally establish Foundation before Practitioner. The absence of a modern combined exam means preparation and scheduling can be staged deliberately.

The staged route also makes readiness easier to diagnose. If OGA-031 performance is unstable, keep working on language precision before investing heavily in Practitioner scenarios. Once Foundation is secure, use OGA-032 preparation to deepen modeling choices, viewpoint selection, and scenario interpretation. The progression mirrors professional development: first learn to speak the language accurately, then learn to use it to communicate architecture decisions.

That separation can be useful. Foundation study can focus on language precision; Practitioner study can then concentrate on applying that language to realistic architecture problems. Candidates coming from an OG0-023 search should not look for a one-for-one current combined replacement because the current pathway is intentionally structured differently.

Legacy OG0-023 material is best used for historical interpretation

Organizations may still encounter ArchiMate 2 diagrams, training records, or employee credentials. Understanding OG0-023 helps interpret those artifacts and explains how earlier practitioners were assessed. It can also show which modeling ideas have remained durable across generations. But a legacy page should make the status explicit so a new learner does not spend months preparing for an unavailable exam.

The practical transition is straightforward: preserve useful architecture-modeling fundamentals, move the specification reference to ArchiMate 3.2, and prepare through OGA-031 and OGA-032. That approach respects the historical credential while keeping current certification decisions aligned with The Open Group’s live program.

Credential records may continue to show ArchiMate 2 achievements even though the corresponding exams are unavailable. That history is legitimate; certification does not become meaningless merely because the assessment generation changes. The practical issue is communication. Resume entries, internal skills inventories, and architecture discussions should identify the version clearly so colleagues can distinguish historical proficiency from current familiarity with the ArchiMate 3.2 language.

If an old practice test presents a question that still seems relevant, translate it into current ArchiMate 3.2 terminology and check whether the relationship or viewpoint remains valid. That conversion exercise extracts durable learning from legacy material without allowing the old exam to define the current syllabus.
