Exam Overview
The TOGAF® Framework Digital Specialist (OG0-DS1) is a knowledge-based certification credential issued by The Open Group, designed to validate an Enterprise Architect's ability to apply the TOGAF Standard within a digital enterprise context. The credential addresses how the TOGAF framework can be used to guide digital transformation initiatives, including digital technology adoption strategies and the practical application of just-enough architecture principles to support the delivery of digital products. It bridges traditional enterprise architecture methodology with the demands of modern digital business, covering topics such as digital technology readiness assessment and Enterprise Architecture as a Service.
As part of The Open Group's TOGAF Certification Credentials portfolio, this credential is structured as a focused, self-contained body of learning—typically requiring 3 or more hours of study—and culminates in a built-in knowledge assessment. Candidates who pass receive an Open Badge and certificate verifiable through Credly. The credential is positioned within the broader TOGAF certification ecosystem alongside other specialist credentials such as TOGAF Agile Specialist, TOGAF EA Leader, and TOGAF Environmentally Sustainable Information Systems Specialist.
Who Should Take This Exam
This credential is intended for practicing Enterprise Architects who already hold a foundational understanding of the TOGAF Standard and want to extend their competency into digital enterprise contexts. It is particularly relevant for architects working in or transitioning to organizations undergoing digital transformation, where they must align enterprise architecture practices with digital product delivery, digital business strategy, and technology adoption roadmaps.
Suitable roles include Enterprise Architects, Solution Architects, IT Strategists, and Digital Transformation Consultants who are responsible for governing or enabling digital initiatives within their organizations. Professionals seeking to demonstrate specialist knowledge in applying TOGAF to digital environments—without undertaking a full multi-day certification—will find this credential an efficient and targeted qualification.
Prerequisites
Candidates are required to hold a TOGAF certification at the Foundation level or higher before attempting the Digital Specialist assessment. This means completion of either the TOGAF 9 Foundation (OG0-091), TOGAF Enterprise Architecture Foundation (OGEA-101), or an equivalent qualifying credential within The Open Group's TOGAF certification portfolio.
Beyond the formal prerequisite, candidates are expected to have practical experience in enterprise architecture and a working familiarity with the TOGAF Architecture Development Method (ADM) and TOGAF Library content. Exposure to digital transformation programs, product delivery methodologies (such as agile or DevOps), and digital technology landscape assessment will significantly aid comprehension of the specialist material.
Exam Format
The OG0-DS1 assessment is delivered as a self-study credential with a built-in online assessment, available directly through The Open Group's shop with 60-day access to the self-study materials and assessment. The assessment is knowledge-based, testing understanding of the learning units covered in the self-study content. Based on provided metadata, the exam lasts 60 minutes and a passing score of 60% is required to earn the credential.

Preview — answers shown1. Crestfield Digital is in Phase D of a TOGAF ADM engagement following the completion of Phase B (Business Architecture) and Phase C (Information Systems Architecture), which defined a microservices-based application architecture and a cloud-native data platform. The team must now define the Technology Architecture. Which three concerns fall within the scope of Phase D work? (Select three!)
Multiple correct answersADefining cloud deployment decisions including selection of IaaS, PaaS, and SaaS service models for the digital platform
BDesigning data governance policies and the master data management strategy for the cloud-native data platform
CSpecifying network topology, security zones, and connectivity requirements across the digital platform components
DIdentifying gaps between current business capabilities and the target operating model defined in the Architecture Vision
EDetermining infrastructure requirements for container orchestration to support the microservices architecture
FDefining the organization's digital business model, revenue streams, and partner ecosystem relationships
Explanation
Phase D (Technology Architecture) focuses on defining the IT infrastructure, technical services, and technology platforms that host and support the digital capabilities designed in Phases B and C. Cloud deployment decisions — selecting IaaS for compute resources, PaaS for managed platform services, and SaaS for business applications — are a central Phase D concern, determining how the digital platform will be hosted, scaled, and operated. Network topology, security zones, and connectivity requirements define how system components communicate securely across the enterprise and with external partners, including firewall zones, API gateway placement, and encrypted channel specifications. Infrastructure requirements for container orchestration, such as Kubernetes cluster architecture, node sizing, networking configuration, and persistent storage, directly enable the microservices application architecture defined in Phase C and are therefore Technology Architecture deliverables. Data governance policies and master data management strategy belong in Phase C Data Architecture, where data flows, data quality rules, and data integration patterns are defined as part of the Information Systems Architecture. Identifying gaps between current and target business capabilities is a Phase B activity, performed as part of developing the target Business Architecture and comparing it to the current baseline. Defining the digital business model and partner ecosystem relationships is a Phase B concern, part of articulating the target business operating model and value chains.
2. Tailspin Bank's enterprise architecture team has completed Phase E and is entering Phase F (Migration Planning) for a digital banking transformation. The target architecture requires decomposing a monolithic core banking system into microservices across a three-year horizon. Regulatory requirements prohibit taking the core banking system offline during the transition. The team must determine how to safely sequence the migration while managing operational risk. Which two actions most directly align with TOGAF Phase F guidance for sequencing architecture implementation in this context? (Select two!)
Multiple correct answersADefine transition architectures representing intermediate states between the current baseline and the target, allowing the bank to migrate incrementally without disrupting live banking services
BImmediately decommission all legacy monolithic components and rebuild every microservice simultaneously in a parallel environment before a single cutover event
CPrioritize implementation work packages based on business value, dependency chains, and risk to produce a coherent sequenced Architecture Roadmap
DDelegate all sequencing and dependency decisions to individual agile delivery squads without overarching coordination from the enterprise architecture team
EReturn to Phase A to obtain a new Architecture Vision mandate before any Phase F work can begin, since the regulatory constraint represents a fundamental scope change
Explanation
Phase F (Migration Planning) is focused on producing a detailed implementation and migration plan. Defining transition architectures that represent intermediate stopping points between the baseline and target allows incremental migration, managing operational risk and regulatory constraints by keeping live services available throughout the transformation. Prioritizing work packages based on business value, dependency analysis, and risk is the core sequencing activity that produces the Architecture Roadmap during Phase F. Decommissioning all legacy components simultaneously creates unacceptable operational risk and directly violates the regulatory constraint prohibiting system outages. Delegating sequencing without architectural coordination produces fragmented delivery that fails to realize the target architecture coherently. Returning to Phase A for a regulatory constraint is unnecessary; the ADM handles evolving constraints through Requirements Management and iterative cycles without requiring a full restart.
3. An enterprise architecture team at Van Arsdel Ltd. is establishing their EA knowledge library and needs to understand how to correctly navigate the TOGAF Standard 10th Edition. A junior architect asks when the team should reference TOGAF Fundamental Content versus TOGAF Series Guides. Which statement correctly describes the structural relationship between these two components? (Select one!)
ATOGAF Series Guides replace Fundamental Content when an organization operates in a specific deployment context such as digital or agile, with Fundamental Content reserved for traditional waterfall enterprise programs
BTOGAF Fundamental Content is updated dynamically to incorporate emerging practices such as digital transformation and agile delivery, while Series Guides contain the stable ADM core content that changes infrequently
CTOGAF Fundamental Content comprises six stable documents covering universal EA concepts and the ADM updated on approximately 5-10 year cycles, while Series Guides provide evolving context-specific guidance for areas such as digital transformation, agile delivery, and sustainability
DThe TOGAF Library supersedes both the Fundamental Content and Series Guides and serves as the primary reference for context-specific architecture guidance in practical application scenarios
Explanation
The TOGAF Standard 10th Edition (released April 25, 2022) introduced a hub-and-spoke structural model. The hub comprises six stable Fundamental Content documents covering universal EA principles, the Architecture Development Method, the Enterprise Continuum, Architecture Building Blocks, and related core concepts. These are updated infrequently on approximately 5-10 year cycles because they represent enduring, universal principles. The spokes are TOGAF Series Guides surrounding this stable core, providing context-specific and evolving guidance for particular deployment scenarios including digital transformation, agile enterprises, business architecture, and environmentally sustainable information systems. Series Guides are updated more dynamically as new practices emerge. The relationship is not inverted: Fundamental Content is stable while Series Guides evolve. Series Guides do not replace Fundamental Content for any type of organization — they extend and configure it for specific contexts. The TOGAF Library is a separate additional resource portfolio distinct from both the Fundamental Content and Series Guides and does not supersede either component.
4. Cascadia Health is in Phase D of its TOGAF ADM engagement. Business Architecture and Information Systems Architecture have been formally approved in earlier phases. A cloud architect on the team immediately proposes beginning vendor selection for the cloud infrastructure platform to save time. The lead enterprise architect must ensure Phase D follows the correct sequence. What should the team do FIRST in Phase D? (Select one!)
ACreate the Implementation and Migration Plan to sequence technology deployments across the programme
BEstablish architecture contracts with implementation project teams for cloud infrastructure delivery
CConduct vendor selection and issue an RFP for cloud infrastructure services
DDefine the baseline technology landscape and identify gaps against the target architecture requirements inherited from Phases B and C
Explanation
Phase D (Technology Architecture) begins by establishing the baseline — documenting the current technology landscape — and then identifying gaps relative to the target architecture requirements that flow from Business Architecture (Phase B) and Information Systems Architecture (Phase C). Only after defining the target technology architecture can the team appropriately evaluate and select specific vendors or products. Vendor selection and RFPs are procurement activities that follow architectural decisions, not precede them. The Implementation and Migration Plan is a Phase F deliverable, not a Phase D output. Architecture contracts with implementation teams are established in Phase G (Implementation Governance) once solutions have been selected and approved.
5. Riverstone Digital's marketing department has independently subscribed to three SaaS analytics tools, a third-party customer data platform, and a low-code automation tool without engaging the EA team. The CIO discovers this when a security investigation reveals customer PII flowing through an unsecured third-party pipeline. The Enterprise Architect is asked to recommend a long-term governance response. Which approach best aligns with TOGAF digital EA principles for managing shadow IT in a digital enterprise? (Select one!)
AEstablish lightweight governance mechanisms that define clear guardrails within which business units can adopt digital tools, preventing unmanaged integration debt and security exposure without stifling innovation
BCreate a separate shadow IT registry within the Architecture Repository to track unsanctioned tools as observed assets, monitoring them without applying formal governance controls
CIssue an enterprise-wide policy prohibiting all technology adoption without prior EA approval, requiring every SaaS evaluation to pass through a full ADM engagement before purchase
DRetroactively decommission all unsanctioned tools immediately and mandate that business units use only the centrally approved enterprise application portfolio
Explanation
TOGAF digital EA principles recognize that in fast-moving digital enterprises, business units will adopt SaaS and cloud tools independently to solve immediate problems — this behavior is inevitable and not inherently wrong. The EA team's role is not to prohibit innovation but to govern it through lightweight, enabling mechanisms: pre-approved vendor categories, security assessment templates, data classification requirements, integration standards, and approved API patterns that business units can follow independently without requiring a full ADM engagement for every tool. This prevents shadow IT from creating unmanaged integration debt and security exposure while preserving the organizational agility that digital business models require. Blanket prohibition policies are counterproductive in digital enterprises — they push adoption underground rather than into governed channels and damage the EA team's credibility as a business enabler. Retroactive decommissioning causes immediate operational disruption and destroys business unit trust in the EA practice, making future collaboration less likely. A shadow IT registry that only monitors without governing does not address the root cause of ungoverned adoption and would not have prevented the data breach scenario described, because observation without guardrails allows the same insecure patterns to continue.
