ADM and Supporting Guidelines and Techniques

Question 1

Architecture Principles

Answer 1

An initial output of the Preliminary Phase
* A set of general rules and guidelines for the architecture being developed
* The TOGAF standard contains guidelines for developing principles and a
detailed set of generic principles
* Principles are generally established in two key domains:
o Enterprise principles provide a basis for decision‐making throughout an enterprise and dictate how the organization fulfills its mission
o Architecture principles are a set of principles that relate to architecture work.

Question 2

Stakeholder Management

Answer 2

Phase A (Architecture Vision) to identify the key players in the engagement.

Stakeholder management is an important discipline that successful architecture practitioners can use to win support from others. It helps them ensure that their projects succeed where others fail.

Question 3

Architecture Patterns

Answer 3

Provides guidance on using architectural patterns

Question 4

Business Scenarios

Answer 4

Business scenarios are a method used to help identify and understand the business requirements that the architecture must address.

• A business process, application, or set of applications
• The business and technology environment
• The people and computing components (‘‘actors’’) who execute
  the scenario
• The desired outcome of proper execution

Question 5

Gap Analysis

Answer 5

Gap analysis is widely used in the ADM to validate an architecture that is being
developed. The basic idea is to spot gaps between the Baseline Architecture and the
Target Architecture; that is, items that have been deliberately omitted, accidentally
left out, or not yet defined. Gap Analysis is used in Phases B, C, D, and E.

Question 6

Migration Planning Techniques

Answer 6

Describes a number of techniques to
support migration planning in Phases E and F

Question 7

Interoperability Requirements

Answer 7

• Interoperability is ‘‘the ability to share information and services’’.
• Defining the degree to which information and services are to be shared is
  very important, especially in a complex organisation and/or extended enterprise.

Question 8

Business Transformation Readiness Assessment

Answer 8

• Understanding the readiness of an organisation to accept
  change, identifying the issues, and dealing with them in the
  Implementation and Migration Plans is key to successful
  architecture transformation in Phases E and F. An initial
  assessment is carried out in Phase A.
• This is a joint effort between corporate (especially human
  resources) staff, lines of business and IT planners.

Question 9

Risk Management

Answer 9

Describes a technique for managing risk during an architecture/business transformation project

There are two levels of risk that should be considered:
1. Initial Level of Risk: Risk categorisation prior to determining and
implementing mitigating actions.
2. Residual Level of Risk: Risk categorization after implementation of mitigating actions

Question 10

Capability-Based Planning

Answer 10

• Capability‐based planning is a technique that focuses on the
  planning, engineering and delivery of strategic business
  capabilities
• It frames all phases of the architecture development in the
  context of business outcomes, clearly linking the IT vision,
  architectures (ABBs and SBBs), and the Implementation and
  Migration Plans with the corporate strategic, business, and
  line of business plans
