Glossary

45 terms you'll meet in EA work and the TOGAF exams.

ADM (Architecture Development Method) TOGAF
TOGAF's iterative method for developing and managing architecture: Preliminary, phases A–H, plus Requirements Management at the center. Related module →
Application Portfolio Management (APM) Portfolio
Maintaining an inventory of applications with their cost, value, technical health, and ownership, to drive rationalization. Related module →
ArchiMate Modeling
An Open Group modeling language for EA, with layers (business, application, technology) and aspects (active structure, behavior, passive structure). Related module →
Architectural Runway Lean/Agile
In SAFe, the existing code, components, and infrastructure needed to deliver near-term features without excessive redesign. Related module →
Architecture Board Governance
A cross-organizational body that oversees architecture: approves standards, resolves conflicts, and grants dispensations. Related module →
Architecture Content Framework TOGAF
TOGAF's structured model of the outputs architecture work produces, classified as deliverables, artifacts, and building blocks. Related module →
Architecture Contract Governance
A joint agreement between architecture and delivery teams on what will be built, to what standards, and how compliance is checked. Related module →
Architecture Decision Record (ADR) Lean/Agile
A short document capturing one significant decision: its context, the options considered, the decision made, and its consequences. Related module →
Architecture Principle Governance
A durable rule or guideline that informs architecture decisions. TOGAF principles have a name, statement, rationale, and implications. Related module →
Architecture Repository TOGAF
The store of architecture outputs: the metamodel, capability, landscape, standards, reference library, governance log, and more. Related module →
Architecture Vision TOGAF
A high-level, aspirational view of the target architecture produced in ADM Phase A, used to gain stakeholder buy-in and scope the work. Related module →
Baseline Architecture Core
The current-state description of an architecture. TOGAF's name for 'as-is'. Related module →
BIZBOK Business Architecture
The Business Architecture Body of Knowledge from the Business Architecture Guild, covering capability, value stream, information, and organization mapping. Related module →
Building Block TOGAF
A reusable component of capability. Architecture Building Blocks (ABBs) describe what is needed; Solution Building Blocks (SBBs) describe how it is delivered. Related module →
Business Capability Business Architecture
What an organization does or can do, independent of who does it or how, e.g. 'Customer Onboarding' or 'Payment Processing'. Related module →
C4 Model Modeling
Simon Brown's lightweight approach to diagramming software at four zoom levels: Context, Containers, Components, and Code. Related module →
Capability Map Business Architecture
A hierarchical, stable model of all business capabilities, often heat-mapped to show investment, maturity, or risk. Related module →
Chief Architect Roles
The leader of the architecture function, typically accountable to the CIO/CTO for architecture direction and governance. Related module →
Concern Core
An interest a stakeholder has in a system, such as cost, security, or time to market. Views are chosen to address concerns. Related module →
Conway's Law Core
Systems tend to mirror the communication structures of the organizations that build them; architecture and org design are linked. Related module →
Dispensation Governance
A time-limited, approved exception allowing a project to deviate from an architecture standard. Related module →
Domain Architect Roles
An architect who owns one domain across the enterprise, such as data, security, integration, or business. Related module →
Enterprise Architecture (EA) Core
The discipline of describing how an organization's business, information, applications, and technology fit together today, how they should fit in future, and guiding the changes to get there. Related module →
Enterprise Continuum TOGAF
TOGAF's way of classifying architecture and solution assets from generic (foundation) to organization-specific, to help reuse. Related module →
Fitness Function Lean/Agile
An objective, ideally automated, check of how well a system meets an architectural characteristic, such as latency or dependency rules. Related module →
Gap Analysis Core
Comparing baseline and target architectures to identify what must be added, changed, or removed. Related module →
Guardrail Lean/Agile
A boundary teams can work within without asking permission, often automated. A lighter alternative to approval gates. Related module →
Operating Model Business Architecture
How an organization delivers value: the integration and standardization of its processes, data, and organization. Related module →
Pace-Layered Architecture Portfolio
Gartner's model classifying applications as Systems of Record, Differentiation, or Innovation, each changing at a different rate. Related module →
Paved Road / Golden Path Lean/Agile
A well-supported default way of building and running software that makes the right choice the easy choice. Related module →
Preliminary Phase TOGAF
The ADM phase that prepares the organization for architecture work: defines the EA capability, principles, framework tailoring, and governance. Related module →
Reference Architecture Core
A reusable template solution for a recurring problem, e.g. 'event-driven integration', that teams adapt rather than reinvent. Related module →
Requirements Management TOGAF
The central, continuous ADM process that captures architecture requirements and manages their flow through every phase. Related module →
Solution Architect Roles
An architect responsible for the design of a specific solution or program, working within enterprise direction. Related module →
Stakeholder Core
Anyone with an interest in, or concerns about, an architecture or the outcomes it affects. Related module →
Target Architecture Core
The desired future state of an architecture, the 'to-be'. Usually described at several levels of detail. Related module →
Technical Debt Core
The future cost of rework created by choosing an expedient solution now. EA manages it at portfolio rather than codebase scale. Related module →
Technology Radar Lean/Agile
A visual, regularly updated view of technologies classified as Adopt, Trial, Assess, or Hold. Related module →
TIME Model Portfolio
Gartner's classification for application rationalization: Tolerate, Invest, Migrate, Eliminate. Related module →
TOGAF TOGAF
The Open Group Architecture Framework: a widely used, vendor-neutral EA framework built around the ADM, a content framework, and guidance on governance and capability. Related module →
