TOGAF® Poster Series #91ArchiMate and TOGAF Synergy

In this poster, we introduce the potential for synergy in using both the TOGAF 9.1 framework and the ArchiMate 2.1 modeling language.

We identify the mappings between these standards, as well as highlight the strengths of each standard, allowing you to identify where each standards may add the most value to your architecture practice and organization.

Archimate 2.1 ExtensionsA number of TOGAF Views are not supported by the ArchiMate Core Language.

The ArchiMate CORE does not address high level strategic or motivational viewpoints, or detailed system development concepts.

ArchiMate Extensions where introduced to support these additional areas within the TOGAF ADM.

The ArchiMate Motivation Extension supportsconcepts such as Goals, Principles and Requirements

which are addressed in Preliminary, Phase A, H and Requirements Management in the TOGAF ADM

The ArchiMate Implementation and Migration

Extension supports concepts in the Phases E, F and G of the TOGAF ADM.

TOGAF ADM

ArchiMate

ArchiMate 2.1 and the TOGAF 9.1 ADMArchiMate and TOGAF are complimentary architecture standards with different focuses.

ArchiMate provides a standard, independent set of architecture concepts and Views.

The structure of the ArchiMate Language is aligned with the TOGAF ADM Core;

TOGAF ADM Phases B, C, D align with the three ArchiMate Layers (Business, Application and Technology) which make up the ArchiMate Core Language Structure.

Differences between ArchiMate and TOGAF AREA ArchiMate 2.1 TOGAF 9.1Focus Multi-purpose Modelling Language and Notation Architecture Development Method

Artefacts Diagrams only (pictorial) Diagrams, Documents, Catalogues and Matrices

Stakeholder Defined stakeholder viewpoint structure for addressing audience concerns and objectives

Defined set of architectural artefacts (architecture content framework) without level of abstraction or target audience

Concepts No distinction between logical and physical concepts Well defined distinction between logical and physical concepts.

Structure High-level generic meta-model structure, with detailed meta-models per layer (Business,Application, Technology)

Single, highly detailed, holistic meta-model

Relationships Simplified basic set of structural and dynamic relationships Multiple relationships specific to each concepts

SummaryUsing ArchiMate strengths to support the TOGAF ADM will ensure synergy and enhance value added by the architecture practice;1. ArchiMate Viewpoint Structure ensures targeted artefacts and outcomes,

addressing specific stakeholder concerns;2. TOGAF ADM provides detailed guidance on developing an Enterprise Architecture;3. ArchiMate Modelling Language provides easy to understand modelling concepts

and an attractive notation;4. TOGAF separates logical and physical artefacts well5. ArchiMate offers a simplified meta-medel and relationship structure allowing

complementalization and piecemeal adoption.

The ArchiMate and TOGAF Harmonization project (Project Harmony) is currently under way (April 2015) and will ensure better alignment with viewpoints and concepts ofArchiMate and TOGAF, including:1. Glossary Alignment2. Viewpoint Mapping3. Meta-model Alignment
