Requirements management spans all ADM phases, ensuring that business, technical, and stakeholder requirements are captured, analyzed, and incorporated. Candidates must recognize the importance of traceability, prioritization, and impact assessment. The OGEA-101 exam frequently presents scenarios where candidates identify how requirements influence phase outputs, align with architecture principles, or inform decision-making.

ADM also emphasizes iteration. Candidates must understand that phases may not be strictly linear; multiple iterations may occur within and across phases. Iterative cycles allow continuous refinement, stakeholder validation, and incremental delivery of value. Scenario-based questions may present candidates with non-linear processes, asking how to apply ADM iterations effectively to maintain alignment, manage risks, and ensure compliance.

Techniques supporting ADM include business scenarios, gap analysis, and architecture principles. Business scenarios define objectives, constraints, and stakeholder needs, guiding phase activities. Gap analysis identifies discrepancies between baseline and target architectures, informing transition planning. Principles provide consistent guidelines across ADM phases. Candidates must know the application and interrelation of these techniques to answer OGEA-101 questions accurately.

Deliverables are another essential component of ADM. Catalogs, matrices, and diagrams support communication, analysis, and decision-making. Candidates must understand the purpose of each deliverable type, how they relate to phases, and their practical use in governance and implementation. OGEA-101 scenarios often ask candidates to determine which deliverable is most appropriate for a specific ADM activity or stakeholder concern.

The ADM also includes architecture content frameworks, which provide structured approaches for organizing artifacts and deliverables. Candidates must understand how frameworks support consistency, traceability, and reuse of components. Exam questions may involve mapping deliverables to phases, applying frameworks to ensure governance compliance, or evaluating how artifacts support iterative cycles.

Integration between ADM phases is a recurring concept. Candidates should recognize dependencies, information flows, and feedback loops. For instance, outputs from business architecture inform information systems and technology architecture, which in turn influence migration planning and implementation governance. OGEA-101 scenarios often test candidates on identifying interdependencies, sequencing phases, and ensuring alignment throughout the ADM lifecycle.

Key success factors in applying ADM include stakeholder engagement, alignment with business strategy, iterative refinement, governance compliance, and practical application of techniques. Candidates should understand how these factors enhance architecture quality, mitigate risks, and deliver measurable business value. Exam questions frequently assess a candidate's ability to apply ADM principles to scenarios involving organizational change, technology adoption, or process improvement.

Practical study tips for mastering ADM include creating phase-specific summaries, practicing scenario-based questions, mapping techniques to phases, and reviewing deliverable types. Candidates benefit from connecting theoretical concepts to practical examples, such as enterprise case studies or architecture frameworks used in real-world organizations. This approach ensures comprehension beyond memorization, aligning knowledge with exam expectations.

Candidates must also understand ADM terminology, including work packages, transition architectures, gap analysis, architecture principles, and building blocks. Familiarity with these terms allows candidates to interpret scenario questions accurately and select appropriate solutions. OGEA-101 emphasizes applied understanding, so memorization must be complemented with practical application.

Architecture Governance and Compliance in OGEA-101

Architecture governance is a critical concept in the OGEA-101 exam, as it ensures that enterprise architecture aligns with organizational objectives, follows established principles, and maintains compliance with both internal and external standards. Governance provides the oversight, structure, and accountability needed to implement architecture effectively and sustainably. Candidates must understand not only the theoretical aspects of governance but also practical applications, including compliance monitoring, decision-making processes, and stakeholder management.

Governance begins with establishing principles, which are high-level statements guiding architecture development. Principles influence decisions, prioritize actions, and provide a foundation for consistency across the enterprise. Examples include security first, interoperability, reusability, and standardization. Candidates must be able to identify appropriate principles for given organizational contexts and apply them across ADM phases. Exam questions often present scenarios requiring candidates to select principles that resolve conflicts or align initiatives with strategic objectives.

Policies are operational rules that enforce architecture principles. They provide a concrete mechanism for guiding decisions, ensuring adherence to best practices, and maintaining alignment with the organization’s vision. Understanding the relationship between principles and policies is essential, as policies operationalize principles into actionable guidelines. Candidates may encounter scenario-based questions in OGEA-101 where they need to determine which policy applies to a specific architectural decision or situation.

Compliance criteria measure adherence to principles and policies. They provide objective standards against which architecture outputs, projects, or initiatives are evaluated. Candidates must understand how to define, monitor, and assess compliance criteria to ensure that solutions meet organizational and regulatory requirements. Scenario questions often test the candidate’s ability to evaluate compliance in a given context, considering factors such as risk, impact, and alignment with business objectives.

Roles and responsibilities form a critical component of architecture governance. The Architecture Board, typically composed of senior architects and stakeholders, provides oversight, approves deliverables, and ensures alignment with principles and policies. Candidates must understand the functions of governance roles, including decision-making authority, accountability, and communication responsibilities. OGEA-101 scenarios may present governance challenges, asking candidates to assign appropriate responsibilities or evaluate role effectiveness.

Architecture contracts are another governance tool, establishing formal agreements between architecture teams, stakeholders, and project teams. These contracts define responsibilities, deliverables, and compliance expectations. Candidates should understand the purpose and components of architecture contracts, including service-level agreements, quality standards, and review mechanisms. Exam questions often involve evaluating whether contracts support governance objectives or ensure compliance with enterprise standards.

Compliance assessments are practical techniques used to verify adherence to architecture principles and policies. Candidates must understand how to conduct assessments, document findings, and recommend corrective actions. This process involves evaluating deliverables, reviewing projects, and ensuring that solutions meet organizational and regulatory requirements. OGEA-101 may present candidates with hypothetical scenarios requiring the design of assessment strategies or the interpretation of compliance results.

Architecture governance integrates closely with ADM phases. During architecture vision, governance ensures alignment with business strategy and stakeholder expectations. In subsequent phases, governance monitors progress, evaluates deliverables, and enforces principles. Migration planning and implementation governance use compliance criteria and assessments to maintain alignment between planned and executed architectures. Understanding these integrations is vital for scenario-based questions in the OGEA-101 exam.

Stakeholder engagement is a key aspect of governance. Effective governance requires identifying stakeholders, capturing their concerns, and integrating feedback into architecture development. Candidates must understand techniques for stakeholder analysis, prioritization, and communication. Scenario-based questions may require candidates to recommend engagement strategies or identify the most relevant stakeholders for a specific ADM phase.

Risk management is closely tied to governance. Architecture governance ensures that risks related to compliance, implementation, and alignment are identified, evaluated, and mitigated. Candidates must understand techniques for risk assessment, including impact analysis, probability estimation, and mitigation planning. OGEA-101 scenarios may present candidates with risks affecting multiple ADM phases, requiring recommendations for mitigation while maintaining alignment with enterprise principles.

Metrics and performance indicators provide evidence for governance effectiveness. Candidates must understand how to define, measure, and interpret metrics related to compliance, efficiency, and alignment. Metrics may include the number of compliant deliverables, adherence to timelines, or stakeholder satisfaction. Exam questions often require candidates to evaluate governance performance based on given metrics or recommend actions to improve compliance.
