(Part VII) 10, 11, 12

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

TOGAF 9.1 Training Copyright 2012 Enterprise Architects v1.8 Module 03 Slide 4 of 29

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

TOGAF 9.1 Training Copyright 2012 Enterprise Architects v1.8 Module 03 Slide 5 of 29

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

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

TOGAF 9.1 Training Copyright 2012 Enterprise Architects v1.8 Module 03 Slide 11 of 29

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

Identify candidate Architecture Roadmap components

TOGAF 9.1 Training Copyright 2012 Enterprise Architects v1.8 Module 03 Slide 13 of 29

Objectives of ADM PhasesPhase C Information Systems Architectures

Objectives of Phase C

Develop the Target Information Systems (Data and Application) Architecture, describing how the enterprises Information Systems Architecture will enable the Business Architecture and the Architecture Vision, in a way that addresses the Request for Architecture Work and stakeholder concerns

Identify candidate Architecture Roadmap components based upon gaps between the Baseline and Target Information Systems (Data and Application) Architectures

TOGAF 9.1 Training Copyright 2012 Enterprise Architects v1.8 Module 03 Slide 14 of 29

Objectives of ADM PhasesPhase D Technology Architecture

Objectives of Phase D

Develop the Target Technology Architecture that enables the logical and physical application and data components and the Architecture Vision, addressing the Request for Architecture Work and stakeholder concerns

Identify candidate Architecture Roadmap components based upon gaps between the Baseline and Target Technology Architectures

Phases B, C and D are the Domain Architecture Phases

TOGAF 9.1 Training Copyright 2012 Enterprise Architects v1.8 Module 03 Slide 15 of 29

Objectives of ADM PhasesPhase E Opportunities and Solutions

Objectives of Phase E

Generate the initial complete version of the Architecture Roadmap, based upon the gap analysis and candidate Architecture Roadmap components from Phases B, C, and D

Determine whether an incremental approach is required, and if so identify Transition Architectures that will deliver continuous business value

TOGAF 9.1 Training Copyright 2012 Enterprise Architects v1.8 Module 03 Slide 16 of 29

Objectives of ADM PhasesPhase F Migration Planning

Objectives of Phase F

Finalise the Architecture Roadmap and the supporting Implementation and Migration Plan

Ensure that the Implementation and Migration Plan is coordinated with the enterprises approach to managing and implementing change in the enterprises overall change portfolio

Ensure that the business value and cost of work packages and Transition Architectures is understood by key stakeholders

Phase F marks the end of architecture development and the beginning of implementation
