TOGAF®-certified enterprise architecture: assessment, ADM delivery and governance by the Portamus team.
Understanding TOGAF® Enterprise Architecture — Certification & Portfolio | Portamus
What Is TOGAF
TOGAF (The Open Group Architecture Framework) is the most widely adopted enterprise architecture framework in the world: a methodology plus the Architecture Development Method (ADM), covering business, application, data and technology architecture. Our article "What is TOGAF?" explains the framework fundamentals (ADM phases, domains, metamodel).
Who Uses TOGAF
More than 80% of Fortune 500 companies use TOGAF to plan, design, and govern their enterprise architectures. It is the global standard for EA across DAX 30 companies, public administrations, and mid-market enterprises undertaking digital transformation — our mid-market tailoring experience is documented in our TOGAF and enterprise architecture practice series.
Portamus & TOGAF
Portamus holds TOGAF® certification and applies the ADM in every EA engagement. This means clients benefit from a proven, structured approach rather than ad-hoc architecture work — from initial architecture vision through to implementation governance.
Where Most Organisations Get Stuck
No Architecture Blueprint
Unclear EA Scope
Missing Architecture Artefacts
Governance Gaps
Key Requirements
The four TOGAF architecture domains — Business, Application, Data, Technology — form Portamus's defined delivery scope for every architecture phase; framework context and ADM background in our blog article "What is TOGAF?".
Business Architecture
Defines the business strategy, governance, organisation, and key business processes — the foundation all other architecture domains build upon; each ADM phase delivers its artifacts and reviews (details in the article "What is TOGAF?").
Application Architecture
Provides a blueprint for individual application systems to be deployed, their interactions, and their relationship to the core business processes.
Data Architecture
Describes the structure of an organisation's logical and physical data assets and how they are managed across the enterprise — from data inventory to logical data architecture to governance roles (Data architecture and TOGAF: fundamentals article, data architecture section).
Technology Architecture (IT Architecture)
Defines the software and hardware capabilities, platforms, networks and operating landscapes required to support the deployment of business, data, and application services — IT architecture as TOGAF phase D (fundamentals article, domains section).
Architecture Governance
Ensures architecture decisions are made consistently, documented, and enforced through an Architecture Review Board and governance framework.
Scope of Engagement
TOGAF Assessment
A structured review of existing architecture practices against the TOGAF ADM to identify gaps and maturity levels.
ADM Implementation Support
Guided execution of each ADM phase — from Preliminary Phase through Architecture Governance — tailored to your organisation.
Architecture Artefact Development
Creation of all required TOGAF artefacts: architecture vision, business/application/data/technology architecture documents, and migration plans.
ARB Setup & Facilitation
Establishment and facilitation of an Architecture Review Board to govern architecture decisions going forward.
TOGAF Enablement
Knowledge transfer and practical training to embed TOGAF understanding in your architecture team.
What You Walk Away With
Architecture Vision Document
A stakeholder-approved statement of the target architecture, scope, and business value of the EA programme.
ADM Phase Artefacts
Complete architecture documentation across Business, Application, Data, and Technology domains.
Architecture Roadmap
A prioritised, sequenced migration plan from current state to target architecture.
ARB Charter & Governance Framework
Documented governance structure, decision rights, and review process for ongoing architecture management.
Architecture Compliance Reports
Formal compliance reviews confirming that implementation projects conform to the approved architecture.
What Changes Once You're Certified
Coherent Enterprise Architecture
Structured Governance
Accelerated Decision-Making
Reduced Architecture Risk
Enabled Digital Transformation
How We Structure This Engagement
Preliminary Phase
Define the organisational context, establish architecture principles, and configure the TOGAF framework to your enterprise's specific needs.
Architecture Vision
Develop the high-level architecture vision and obtain stakeholder sign-off on scope, business value, and target state.
Architecture Development
Systematically develop Business, Application, Data, and Technology architectures across ADM phases B–D (all phases from Preliminary through H explained in the fundamentals article), producing all required artefacts.
Migration Planning
Create a detailed, prioritised transition roadmap from the current state to the target architecture, including project sequencing.
Architecture Governance
Establish the ARB, implement compliance reviews, and set up ongoing architecture management processes.
Services that commonly pair with this engagement.
TOGAF® is the foundation of every Portamus enterprise architecture engagement. As a TOGAF®-certified firm, Portamus applies the Architecture Development Method (ADM) systematically to your specific organisational reality — from the initial architecture vision through to long-term governance.
TOGAF is a method, not a modelling language: it describes how architecture work is done, while ArchiMate provides the notation to express it. Our detailed comparison TOGAF vs. ArchiMate: Differences & Comparison covers scope, certification, tooling and cost, and when you need which. For the framework basics, see What is TOGAF?.
