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.
The credential format is notably lighter than full TOGAF certifications such as the TOGAF EA Practitioner—it is designed for focused, modular professional development rather than comprehensive multi-domain examination. The question type consists of objective knowledge questions aligned to the learning units in the Digital Specialist study materials. Specific question counts are not publicly published by The Open Group for this credential type; candidates should refer to the official introduction document available on the certification portal for the most current assessment specifications.

Preview — answers shown1. Grafton Media Group is in Phase D of a TOGAF ADM digital transformation engagement, transitioning from an on-premises data center to a hybrid cloud model to support new digital content delivery services. The architecture team is reviewing a backlog of pending decisions to determine which properly belong within Phase D versus decisions that should have been addressed in earlier phases. Which of the following decisions is MOST appropriate for Phase D of the TOGAF ADM? (Select one!)
ASelecting Kubernetes as the container orchestration infrastructure for the hybrid cloud deployment
BDefining the API contracts and integration patterns between microservices in the new content delivery platform
CMapping customer journey touchpoints to the supporting business capabilities required for digital content delivery
DEstablishing data governance policies and retention rules for the new streaming analytics pipeline
Explanation
Phase D, Technology Architecture, is where decisions about infrastructure platforms, cloud deployment models, and IT service delivery are formally made. Selecting Kubernetes as the container orchestration infrastructure is a technology layer decision that properly belongs in Phase D, as it addresses the deployment and operational infrastructure rather than application design or data management. Defining API contracts and integration patterns between microservices is a Phase C Application Architecture activity, where the application landscape, integration topology, and service interactions are designed. Establishing data governance policies and retention rules for a streaming analytics pipeline is a Phase C Data Architecture concern, addressing data flows, management standards, and integration. Mapping customer journey touchpoints to business capabilities is a Phase B Business Architecture activity focused on business capability modeling and the relationship between customer interactions and organizational processes.
2. A healthcare enterprise architect at Northwind Health Systems is organizing assets within the Architecture Repository using the Enterprise Continuum. She has identified four assets to classify: a generic cloud computing reference architecture, the HL7 FHIR interoperability standard for healthcare data exchange, the organization's internally configured patient data platform architecture, and an event-driven microservices communication pattern applicable across industries. She needs to correctly position the HL7 FHIR healthcare interoperability architecture within the Enterprise Continuum spectrum. Which Enterprise Continuum level is the correct classification for this asset? (Select one!)
ACommon Systems Architecture, because FHIR defines structured patterns that can be applied across multiple types of information systems
BIndustry Architecture, because FHIR is a domain-specific reference architecture designed exclusively for the healthcare sector
CFoundation Architecture, because FHIR is a widely adopted open standard used by many organizations across multiple contexts
DOrganization-Specific Architecture, because FHIR has been selected and is being actively implemented by this organization
Explanation
The Enterprise Continuum spans four levels from most generic to most specific. Foundation Architectures contain generic reference models applicable universally regardless of industry, such as cloud computing reference architectures. Common Systems Architectures contain cross-industry patterns reusable in many sectors, such as event-driven microservices communication patterns or API gateway patterns. Industry Architectures contain sector-specific reference models designed for a particular vertical domain, providing standardized guidance tailored to that industry's unique requirements and regulatory environment. Organization-Specific Architectures are configurations an enterprise has tailored to its own context, built upon inputs from the other levels. HL7 FHIR is a domain-specific interoperability standard created exclusively for healthcare data exchange, making Industry Architecture its correct Enterprise Continuum position. The generic cloud reference architecture belongs at Foundation Architecture. The event-driven microservices pattern belongs at Common Systems Architecture. The organization's configured patient data platform, built using FHIR as a reference input, belongs at Organization-Specific Architecture.
3. Galbraith Digital, a mid-sized insurance company, has accumulated 47 separate customer data systems across its life, property, and commercial business lines over 20 years. Each business unit independently acquires software, resulting in fragmented data and the inability to create a unified customer view for digital services. The CIO has commissioned an enterprise architecture program to address this situation. Which two EA capabilities directly address the challenges Galbraith Digital is facing? (Select two!)
Multiple correct answersAEnsuring compliance with digital regulatory frameworks such as GDPR and the AI Act
BReducing IT complexity by identifying and eliminating duplication and redundancy across IT systems
CDesigning the target application architecture for new digital mobile customer engagement channels
DBreaking organizational silos and improving collaboration between business and IT teams
EEstablishing a formal Architecture Board to provide governance oversight across the enterprise
Explanation
Reducing IT complexity by identifying and eliminating duplication and redundancy directly addresses the 47 fragmented customer data systems — eliminating redundant systems and consolidating data assets is one of EA's core contributions to digital enterprises. Breaking organizational silos and improving collaboration between business units addresses the root cause: independent business lines acquiring software without coordination creates the fragmentation that prevents a unified customer view. GDPR compliance is a benefit EA can enable but is not the capability that directly resolves system fragmentation. Designing mobile application architecture is a Phase C activity focused on future digital channels, not on resolving existing system redundancy. Establishing an Architecture Board provides governance infrastructure but is not itself the EA capability that directly reduces complexity and organizational silos.
4. Contoso Digital is launching a new data monetization service that will form part of a broader platform business model. The enterprise architect has been asked to formally document the new digital business model, define organizational capabilities required for the platform strategy, and identify the processes that will need to change to support ecosystem partners. In which ADM phase should this work primarily be conducted? (Select one!)
APhase C – Information Systems Architecture
BPhase E – Opportunities and Solutions
CPhase A – Architecture Vision
DPhase B – Business Architecture
Explanation
Phase B (Business Architecture) is the ADM phase where digital business models are formally articulated, including platform business models, ecosystem plays, subscription models, and data monetization strategies. It defines business structure, processes, capabilities, and gaps. Phase A establishes the transformation vision and obtains permissions to proceed but does not go into the depth of business model articulation required here. Phase C covers the data and application architectures that technically support the business design, not the business model definition itself. Phase E identifies implementation opportunities and builds the roadmap, but it assumes that business and system architectures are already defined in prior phases.
5. An enterprise architect at Northbeck Digital is introducing the four TOGAF architecture domains to a business stakeholder who is new to enterprise architecture. The stakeholder asks which domain is specifically responsible for defining how data flows across the organization's digital services, how data is managed and governed over its lifecycle, and how data is integrated between systems. Which architecture domain correctly addresses these concerns? (Select one!)
ABusiness Architecture, because data flows are ultimately driven by business processes and organizational accountability structures
BApplication Architecture, because applications and microservices are the systems that generate, transform, and expose data to consumers
CData Architecture, which specifically covers data flows, data management, data governance, and integration patterns across digital services
DTechnology Architecture, because the infrastructure platforms — including databases, data lakes, and messaging brokers — physically store and process the data
Explanation
Data Architecture is the TOGAF domain specifically responsible for defining how data flows across the enterprise, how it is managed, governed, and integrated between systems. This domain addresses data models, data lifecycle management, data integration patterns, and ensuring data quality and consistency across digital services — concerns that cut across multiple applications, business processes, and technology layers. While Business Architecture defines the processes that generate and consume data, Application Architecture defines the systems and APIs that expose data, and Technology Architecture defines the infrastructure that stores and processes data, none of these domains own the cross-cutting concerns of data governance, data flow design, and enterprise-wide data integration. These are the explicit responsibilities of Data Architecture, addressed within Phase C of the ADM alongside Application Architecture.
