Master Enterprise Architecture:TOGAF® 10 -OGEA-101 Exam Prep

Architecture principles serve as enduring rules that guide decisions across projects and teams, align IT choices with enterprise strategy, and provide a governance framework for standardization, interoperability, and cost optimization.

Explore the bdat architecture domains—business, data, application, and technology—and how they interrelate, map to the adm, and drive complete enterprise architecture.

Explore architecture scopes through the scope cube, balance breadth, depth, and time period, and determine the minimum breadth needed to avoid waste and drive practical enterprise decisions.

Explore baseline, target, and transition architectures as a phased journey from current state to desired state, using gap analysis to plan value-delivering, risk-mitigated transitions.

Navigate three architecture landscape levels—strategic, segment, and capability—cascading vision into coherent solutions while feedback travels upward for continuous learning.

Partition enterprise architecture into smaller, well-defined parts to enable parallel work, maintain alignment, and scale governance across business units, geographies, and initiatives.

Build and reuse architecture building blocks and solution building blocks to create scalable enterprise architectures. Document interfaces, ownership, and lifecycle in a catalog to ensure governance and consistency across domains.

Explore architecture views and viewpoints, using reusable templates to tailor information for stakeholders. Learn common viewpoints like business capability, application portfolio, data flow, technology stack, and security.

Explore gap analysis in TOGAF 10, identifying differences between current and desired states, and convert gaps into work packages and an architecture roadmap across business, data, application, and technology domains.

Create and fill a gap analysis matrix that compares baseline and target architectures using ABBs, marking included, eliminated, and new entries to guide implementation planning.

Discover architecture patterns and how to use proven building blocks across enterprise domains, guided by ADM guidelines, to enable reuse while balancing context, forces, and trade-offs.

Identify, assess, mitigate, and monitor risks across business and information technology transformation to align with organizational goals and maximize value in enterprise architecture.

Assess readiness to move from baseline to target architecture and bridge the gap between architectural ambition and operational capability.

Master the ADM, TOGAF's eight‑phase, iterative playbook for enterprise architecture, with requirements management at the center guiding continuous, cycle-based evolution.

Establish your enterprise architecture capability, define governance and scope, and follow six steps in the preliminary phase to tailor TOGAF and build an architecture repository.

Phase a architecture vision delivers a compelling elevator pitch, outlining objectives, eight steps, and inputs and outputs to gain approval and align stakeholders with business value and constraints.

Phase B builds the detailed target business architecture, performs gap analysis, and defines a candidate roadmap through nine steps, aligning processes, organization, capabilities, and information flows for future state.

Phase D develops the target technology architecture—detailing infrastructure, cloud or on-premises options, networks, platforms, middleware, and security—and defines a gap-driven roadmap to enable end-to-end business, data, and application design.

Plan the TOGAF phase e by generating the initial architecture roadmap from gap analysis and B–D components, and identify transition architectures for incremental delivery and a concrete implementation plan.

Turn phase e's draft into an execution-ready migration plan with detailed timelines, costs, and dependencies, and align it with the enterprise change portfolio and governance.

Phase g of TOGAF 10 enterprise architecture provides architectural oversight to ensure deployments conform to the target architecture, with continuous compliance reviews, resource alignment, and post-implementation learning.

Drive continuous governance in phase h of TOGAF 10 enterprise architecture, managing architecture change through monitoring, value realization, and a seven-step process that keeps the architecture relevant.

Actively manage the continuous flow of requirements across all ADM phases in TOGAF 10. Feed and receive requirements through the architecture requirements repository to keep the enterprise architecture cohesive.

Define architecture outcomes with the architecture content framework by detailing artifacts, deliverables, and building blocks, aligned to a meta model.

Discover the enterprise architecture standard library, a modular reorganization of the 10th edition separating the normative EA standard from the non-normative series guides for flexible guidance and exam prep.

Learn how a tailored communications plan drives enterprise architecture by aligning stakeholders, content, methods, and timing for clear understanding and action. Identify stakeholders and assign ownership to ensure accountability.

Explore the technical reference model (TRM) as a foundational, vendor-neutral framework with a layered structure—application platform, communication software, communications infrastructure services, and application platform interfaces—that guides architecture decisions.

Architecture governance ensures architecture decisions are controlled, compliant, low-risk, and value-driven, and continuously aligned with business goals to prevent architecture erosion.

Explore how architecture governance ensures value by applying four essentials: architecture board, architecture contracts, compliance reviews, and maturity models scaled to your organization.

Explore a practical enterprise architecture resource kit for togaf 10, featuring templates, deliverables, case studies, and flashcards to streamline architecture vision, scoping, roadmaps, governance, and requirements traceability.

Explore Archimede modeling language, an open and independent visual standard maintained by the Open Group for enterprise architecture, structuring business, application, and technology layers and enabling traceability.
