    Sets targets, KPIs, plans, and budgets for architecture roles

    Business Capability drives the need for Architecture Capability Maturity

    The Architecture Capability operates a method

    The method delivers new business solutions

    Operational changes update the Enterprise Continuum and

    Repository

    The Enterprise Continuum and Repository inform the business of

    current state

    The method produces content to be stored in the Repository, classified

    according to the Enterprise Continuum

    The method refines understanding of business need

    Business need feeds into the method, identifying problems to

    be addressed

    Effective operation of the Architecture Capability ensures

    realization of the Business Vision

    Business Vision and

    Drivers

    Informs the size, structure, and culture of the capability

    Needs of the business shape non-architectural aspects of business operation

    Learning from the business operation creates new business need

    In this Training Module

    This module provides a high-level overview of the TOGAF 9.1 ADM

    We will cover each of the ADM phases in detail in subsequent modules

    This module covers three topics:

    1. Overview of the TOGAF ADM

    2. Objectives of Each ADM Phase

    3. Architecture Development

    Architecture Development Method (ADM)Key Learning Points

    The ADM defines a method for developing an Enterprise Architecture

    The ADM is at the core of TOGAF

    The Architecture Repository will be populated with architecture artefacts

    As the result of multiple iterations of the ADM

    Architecture Repository

    Architecture Artefacts, Views, Building Blocks,

    Deliverables

    Overview of the ADM

    The ADM is iterative

    Over the whole ADM

    Between phases

    Within phases

  • TOGAF 9.1 Training Copyright 2012 Enterprise Architects v1.8 Module 03 Slide 6 of 29

    Overview of the ADM

    Every ADM Phase has five (5) aspects

    1. Objectives Major goals and purposes for the Phase

    2. Approach Considerations and references relevant to the Phase

    3. Inputs Deliverables, endorsements, artefacts, knowledge required to execute the Phase May be outputs from prior Phases or prior iterations of ADM

    4. Steps Actions to be taken to complete the Phase not necessarily in sequence

    5. Outputs Deliverables, endorsements necessary to complete the Phase

    Output and Versioning

    Outputs Architecture Views, Artefacts, Deliverables Architecture outputs are created in each ADM phase Outputs from one ADM Phase are inputs to subsequent Phases

    This numbering scheme is provided as an example only

    Version 0.1 A high-level outline (draft) Likely to evolve through subsequent investigation and discovery

    Version 1.0 A detailed architecture that is formally reviewed and signed off by stakeholders

    1. Overview of the TOGAF ADM

    2. Objectives of ADM Phases

    3. Architecture Development

  • TOGAF 9.1 Training Copyright 2012 Enterprise Architects v1.8 Module 03 Slide 10 of 29

    Objectives of ADM PhasesPreliminary Phase

    Determine the Architecture Capability desired by the organisation: Review the organisational context for conducting enterprise architecture Identify and scope the elements of the enterprise organisations affected by the

    Architecture Capability Identify the established frameworks, methods, and processes that intersect with

    the Architecture Capability Establish Capability Maturity targets (for the architecture function)

    Establish the Architecture Capability: Define and establish the Organisational Model for Enterprise Architecture Define and establish the detailed process and resources for architecture

    governance Select and implement tools that support the Architecture Capability Define the Architecture Principles

    Objectives of ADM PhasesPhase A Architecture Vision

    Objectives of Phase A

    Develop a high-level aspirational vision of the capabilities and business value to be delivered as a result of the proposed enterprise architecture

    Obtain approval for a Statement of Architecture Work that defines a program of works to develop and deploy the architecture outlined in the Architecture Vision

  • TOGAF 9.1 Training Copyright 2012 Enterprise Architects v1.8 Module 03 Slide 12 of 29

    Objectives of ADM PhasesPhase B Business Architecture

    Objectives of Phase B

    Develop the Target Business Architecture that describes how the enterprise needs to operate to achieve the business goals, and respond to the strategic drivers set out in the Architecture Vision, in a way that addresses the Request for Architecture Work and stakeholder concerns
