The Open Agile Architecture Practitioner exam (OGAA-001) has 40 multiple-choice questions in 60 minutes with a 60% (24/40) passing score. The body of knowledge is the Open Agile Architecture Standard, a free Open Group publication that integrates Agile, Lean, DDD, Team Topologies, and evolutionary-architecture practice into an Enterprise Architecture model with four layers (Mission, Operating, Process and Information, System) and an Adaptive Cycle (Sense-Decide-Adapt). O-AA is complementary to TOGAF — it does not replace the ADM but offers Agile-friendly patterns that can be combined with it. The credential is lifetime-valid with no recertification. The exam is delivered at Pearson VUE test centers and via OnVUE remote proctoring; fee is approximately $320 USD per The Open Group's 2026 retail schedule.

1In the Open Agile Architecture (O-AA) Standard, which architecture layer captures the enterprise's purpose, vision, strategic intent, and outcomes that everything else must serve?
A.Operating Architecture
B.System Architecture
C.Mission Architecture
D.Process and Information Architecture
Explanation: Mission Architecture is the topmost O-AA layer — it captures purpose, vision, customer outcomes, and the strategic intent that the rest of the enterprise must serve. Operating Architecture defines how the enterprise organizes to deliver on the mission (value streams, organization), System Architecture covers IT systems and platforms, and Process and Information Architecture describes business processes and the information they consume and produce.
2Which three actions define the Adaptive Cycle described by the O-AA Standard?
A.Plan, Do, Check
B.Sense, Decide, Adapt
C.Build, Measure, Learn
D.Define, Design, Deploy
Explanation: O-AA's Adaptive Cycle is Sense, Decide, Adapt. The enterprise senses signals from customers, markets, and operations; decides where and how to respond; and adapts its architecture and operations accordingly. Build-Measure-Learn is the Lean Startup loop and is referenced by O-AA but is product-level; Plan-Do-Check is Deming's PDCA quality cycle.
3A telecom is shifting from project-funded delivery to product-funded persistent teams. Which O-AA principle most directly supports this change?
A.Big Design Up Front
B.Project-centric organization with temporary teams
C.Product-centric organization with stable cross-functional teams
D.Functional silos with phase gates
Explanation: O-AA advocates moving from project-centric to product-centric organization — funding products, not projects, and keeping cross-functional teams persistent so they accumulate domain knowledge, own outcomes, and continuously evolve their product. Project funding creates handoffs, knowledge loss, and discourages long-term quality investment.
4Conway's Law states that:
A.Systems will eventually replace their designers
B.Organizations design systems that mirror their communication structures
C.Software complexity doubles every 18 months
D.Distributed systems must be eventually consistent
Explanation: Melvin Conway's 1968 observation: any organization that designs a system will produce a design whose structure is a copy of the organization's communication structure. O-AA uses this in reverse — the Inverse Conway Maneuver — to deliberately shape the organization so the desired architecture emerges.
5An architect wants the system to be composed of loosely coupled services owned by autonomous teams. Which technique does O-AA recommend to make the organization match the desired architecture?
A.Inverse Conway Maneuver — restructure teams to mirror the target architecture
B.Big Bang reorganization after the architecture is built
C.Matrix management with shared resources
D.Centralized architecture review board approving every change
Explanation: The Inverse Conway Maneuver deliberately restructures teams so that team boundaries match the target system's component boundaries. Because Conway's Law says architecture mirrors communication structure, intentionally shaping the org first makes the desired loosely coupled architecture easier to achieve and sustain.
6In O-AA, what is the role of the Architecture Backlog?
A.A list of completed architecture artifacts kept for audit
B.A prioritized, evolving list of architecture work items integrated with the product backlog
C.A static document approved at the start of a release
D.The defect log maintained by the QA team
Explanation: The Architecture Backlog is a living, prioritized list of architecture initiatives, enablers, and decisions, integrated with product backlogs so architecture evolves alongside the product. It replaces the up-front architecture document of plan-driven approaches with continuous, just-enough, just-in-time work items.
7Which is the best example of an outcome-based metric (preferred by O-AA) rather than an output-based metric?
A.Number of stories completed per sprint
B.Lines of code written this quarter
C.Reduction in customer onboarding time from 9 days to 1 day
D.Number of deployments per week
Explanation: Outcome metrics measure the change in customer or business state (onboarding time fell, churn dropped, revenue per user grew). Output metrics measure activity (stories, deployments, lines of code). O-AA emphasizes outcomes because activity without outcome is waste; outcomes connect work to mission.
8Which statement best describes a Value Stream in O-AA?
A.A sequence of activities a single team performs to develop software
B.An end-to-end sequence of value-adding stages from trigger to value delivered to a stakeholder
C.A financial reporting structure used by the CFO
D.The list of microservices owned by a product team
Explanation: A Value Stream is an end-to-end set of stages that takes a triggering event and produces a result of value for a stakeholder (typically the customer). O-AA elevates value streams as the central organizing concept, replacing functional silos and project-by-project planning.
9Which O-AA practice helps balance intentional architecture (planned) with emergent architecture (discovered during delivery)?
A.Continuous Architecture
B.Waterfall sign-off
C.PRINCE2 stage gates
D.Frozen requirements baseline
Explanation: Continuous Architecture is the O-AA practice of evolving architecture iteratively, combining intentional decisions made early with emergent discoveries that surface during delivery. It rejects the dichotomy of 'design it all up front' vs 'no architecture at all' in favor of just-enough-just-in-time architecture.
10Which Domain-Driven Design strategic pattern protects a bounded context from the model of a legacy system it must integrate with?
A.Shared Kernel
B.Anti-Corruption Layer
C.Customer-Supplier
D.Conformist
Explanation: An Anti-Corruption Layer translates between two bounded contexts so the legacy model does not corrupt the clean model in the new context. Shared Kernel means two contexts deliberately share a subset of the model; Customer-Supplier defines a directional dependency; Conformist accepts the upstream model as-is.

Open Agile Architecture Practitioner Study Tips from Top Performers

1Memorize the four O-AA layers and what each covers: Mission (purpose, outcomes), Operating (value streams, organization), Process and Information (processes and the information that flows with them), System (IT systems and platforms). Distractors swap these constantly.
2Master the Adaptive Cycle — Sense, Decide, Adapt — and recognize it at the enterprise level, distinct from Build-Measure-Learn (Lean Startup, product level) and PDCA (Deming, quality level).
3Know the difference between Conway's Law (architecture mirrors organization) and the Inverse Conway Maneuver (deliberately shape organization to get the architecture you want). Practitioner questions test this distinction with applied scenarios.
4Drill the DDD strategic patterns until they are automatic: Anti-Corruption Layer (translate to protect a clean model), Shared Kernel (deliberate shared subset), Customer-Supplier (upstream supports downstream backlog), Conformist (downstream accepts upstream model), Open Host Service (published protocol for many consumers).
5Treat NFRs as fitness functions, not as a section of a Word doc. Performance, security, scalability, modularity, and resilience should be objective, automatable checks running continuously in pipelines and production.
6Recognize incremental change patterns: Strangler Fig (route traffic gradually to the new system), Branch by Abstraction (abstraction layer plus parallel implementations on trunk). Big Bang is the wrong answer in O-AA scenarios almost always.
7Understand Team Topologies: stream-aligned (own a value stream end-to-end), platform (build self-service capabilities), enabling (temporary capability-building), complicated-subsystem (deep specialist work). Cognitive load is a first-class design constraint.
8Learn the governance trade-off: O-AA does not eliminate governance; it federates routine decisions to teams within shared principles and fitness functions, reserving central review for genuinely enterprise-wide impacts. Policy as code and continuous compliance make this work in regulated industries.

Frequently Asked Questions

What is the Open Agile Architecture Practitioner certification?

OGAA-001 is The Open Group's practitioner-level certification for the Open Agile Architecture (O-AA) Standard. It validates the ability to apply O-AA — a body of knowledge for doing Enterprise Architecture in an Agile, product-centric, customer-centric, adaptive way. The exam covers the four-layer O-AA model (Mission, Operating, Process and Information, System), the Adaptive Cycle, value streams, Continuous Architecture, DDD, evolutionary architecture, Team Topologies, and federated governance.

How is OGAA-001 different from TOGAF?

TOGAF defines an Enterprise Architecture method (the ADM) and rich content for governance, repositories, and architecture development at any cadence. O-AA is complementary — it codifies Agile, product-centric, evolutionary EA practice. Many practitioners pair them: TOGAF for method and structure, O-AA for Agile-friendly patterns. O-AA is not a TOGAF replacement and does not require TOGAF certification.

How is the OGAA-001 exam structured?

40 multiple-choice questions in 60 minutes; passing score is 60% (24 correct). Closed-book. Questions span the topic areas of the Open Agile Architecture Standard: O-AA concepts and layers, Adaptive Cycle, Operating Architecture and value streams, Continuous Architecture, DDD integration, evolutionary architecture, Team Topologies, event-driven/cloud-native systems, and governance. Delivered at Pearson VUE test centers or remotely via OnVUE.

How much does OGAA-001 cost?

Approximately USD $320 per The Open Group's 2026 retail voucher schedule — verify against the current fee sheet because Open Group fees are periodically revised. Accredited training providers may bundle the voucher with their courses at a discount. There is no application fee — just the exam fee.

How hard is the OGAA-001 exam?

Practitioner-level. Well-prepared candidates with Agile delivery and Enterprise Architecture background generally pass on the first attempt at high rates (~75% industry estimate). The challenge is recognizing applied scenarios that integrate multiple concept families — O-AA layers, DDD, Team Topologies, evolutionary architecture, and governance. Plan 30-50 hours with the free O-AA Standard plus 100+ practice questions.

What study materials are recommended?

The Open Agile Architecture Standard from The Open Group (free download). Supplement with Team Topologies (Skelton & Pais), Building Evolutionary Architectures (Ford, Parsons, Kua), Domain-Driven Design (Evans) and Implementing Domain-Driven Design (Vernon), and Continuous Architecture in Practice (Erder, Pureur, Woods). Practice with 100+ scenario and concept questions and aim for 85%+ on practice tests before scheduling the exam.

Is OGAA-001 valid for life?

Yes — Open Group practitioner credentials carry lifetime validity with no recertification or continuing-education requirement. If The Open Group publishes a major revision of the Open Agile Architecture Standard, a bridging exam is typically offered so existing credential holders can update without retaking the full exam.

Should I take OGAA-001 or a TOGAF Practitioner exam first?

If you are an EA generalist already comfortable with Agile delivery and want Agile-aware practices that can be combined with the TOGAF ADM, OGAA-001 is a fast, focused complement. If your role demands deep TOGAF ADM mastery (Phase A-H scenarios, deliverables, governance artifacts), start with TOGAF EA Practitioner (OGEA-103). Many practitioners take both for breadth + Agile depth.
