    Introduction to Applying the ADM

    This unit explains how the ADM is applied in practice: where guidance lives, how iteration lets phases run concurrently, the three Architecture Landscape levels, partitioning, the four purposes of architecture work, and support for the Digital enterprise.

    Inside this domain

    • Describe where guidance on applying the TOGAF Standard is provided
    • Explain how iteration enables concurrent operation of multiple ADM phases

    The smallest unit on OGEA-101, and a precise one: what Architecture Governance is and why it pays off, what the Architecture Board does, what Architecture Contracts are for, and why compliance must be checked.

    Inside this domain

    • Briefly explain the concept of Architecture Governance
    • Explain why Architecture Governance is beneficial
    • Briefly explain the role of an Architecture Board and its responsibilities
    • Briefly explain the role of Architecture Contracts

    Inside this domain

    • Define stakeholders, concerns, views and viewpoints and the links between them
    • Explain what building blocks are and their use in the ADM
    • Describe the TOGAF deliverables created and consumed in different ADM phases

Practice questionDomain 2: Introduction to the ADM

Target Business, Data, Application and Technology Architectures have been agreed. The architecture team now consolidates the gap analysis results from each domain, groups the changes into work packages, and decides whether the move to the target should be made through intermediate states. Which ADM phase is this?

One trap from every domain

The answer that looks right, and the clue that gives it away.

  • Domain 1

    Continuum equals repository

    Clue Verbs such as 'store', 'hold' or 'record' point to the repository; 'classify', 'position' or 'generic to specific' point to the continuum.

  • Domain 2

    Transition Architectures in Phase F

    Clue 'Determine', 'identify' or 'initial' points to E; 'finalize', 'cost' or 'prioritize' points to F.

  • Domain 3

    Benefits in Implications

    Clue If the sentence says why the business gains, it is Rationale; if it says what the organization must do, it is Implications.

  • Domain 4

    Continuum levels as landscape levels

    Clue 'Architecture Landscape' and 'three levels' point to Strategic, Segment, Capability; 'continuum' points to the four-level generic-to-specific list.

  • Domain 5

    Compliant means complete

    Clue 'Plus additional features' points to Conformant; 'some features not implemented' points to Compliant.

  • Domain 6

    Viewpoint is what you see

    Clue 'Conventions', 'template' or 'how to construct' means viewpoint; 'representation of the system' means view.
