01_TOGAF Architecture Development Method (ADM) Flashcards
1
Q
What is the ADM about?
A
The ADM is the core of TOGAF.
The ADM is a step-by-step approach to develop and manage the lifecycle of an enterprise architecture.
The Method is a defined, repeatable approach to address a particular type of problem.
2
Q
Where can the ADM in TOGAF be found?
A
The ADM is described in Part II, the Architecture Development Method (ADM).
3
Q
Describe the ADM scope
A
The ADM comprises a series of linked phases which enable the full life-cycle management of an Enterprise Architecture from planning to operational deployment and change.
- Preliminary
- Architecture Vision
- Business Architecture
- Information Systems Architecture
- Technology Architecture
- Opportunities & Solutions
- Migration Planning
- Implementation Governance
- Architecture Change Management
4
Q
The Preliminary Phases Objectives
A
This Preliminary Phase is about defining “where, what, why, who, and how we do architecture”
Determine the Architecture Capability desired by the organization:
- Review the organizational context for conducting Enterprise Architecture
- Identify and scope the elements of the enterprise organizations affected by the Architecture Capability
- Identify the established frameworks, methods, and processes that intersect with the Architecture Capability
- Establish Capability Maturity target
Determine and establish the Architecture Capability:
- Define and establish the Organizational 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
5
Q
The activities of the Preliminary Phase (A) are …
A
- establish organizational context
- identify sponsor (and other) stakeholders
- gain commitment to the approach
- define enterprise scope
- define “architecture footprint”
- define framework and detailed methods
- confirm governance framework
- select supporting tools and infrastructure
- define architecture principles
- architecting the enterprise observation
- establish organizational context by providing input to the Requirements Management process to initiate the Architecture Vision Phase (A)
6
Q
Objectives of the Architecture Vision Phase (A) are ,,,
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
7
Q
The Activities of the Architecture Vision Phase (A) are …
A
- ensure this architecture evolution has recognition and support
- define and organize an architecture development cycle
- validate business principles, goals, drivers
- establish enterprise architecture KPIs
- define scope and components
- define relevant stakeholders, their concerns and objectives
- define key business requirements to be addressed
- articulate an Architecture Vision
- create a comprehensive plan
- secure formal approval to proceed
- understand the impact on and of other parallel architecture development cycles
8
Q
The objectives of the Business Architecture Phase (B) are to …
A
- 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 Statement of Architecture Work and stakeholder concerns
- Identify candidate Architecture Roadmap components based upon gaps between the Baseline and Target Business Architectures
9
Q
The Activities of the Business Architecture Phase (B) are …
A
- To describe the Baseline Business Architecture
- To develop a Target Business Architecture, describing the product and/or service strategy, and the organizational, functional, process, information, and geographic aspects of the business environment, based on the business principles, business goals, and strategic drivers
- To analyse the gaps between the Baseline and Target Business Architectures
- To select and develop the relevant architecture viewpoints that will enable the architect to demonstrate how the stakeholder concerns are addressed in the Business Architecture
- To select the relevant tools and techniques to be used in association with the selected viewpoints
10
Q
The objectives of the Information Systems Architecture Phase (C) are to…
A
- Develop the Target Information Systems Architectures, describing how the enterprise’s Information Systems Architecture will enable the Business Architecture and the Architecture Vision, in a way that addresses the Statement of Architecture Work and stakeholder concerns
- Identify candidate Architecture Roadmap components based upon gaps between the Baseline and Target Information Systems (Data and Application) Architectures
11
Q
What is Data Architecture all about?
A
Define the major types and sources of data
- understandable by stakeholders
- complete and consistent
- data entities
12
Q
What is Application Architecture all about?
A
Define the major kinds of application systems
- to process the data
- to support the business
- logical group of capabilities
13
Q
The activities of the Information Systems Architecture Phase (C) are …
A
- To describe the Baseline Information System Architecture
- To develop a Target Information System Architecture by identifying and defining the applications and data considerations that support an enterprise’s Business Architecture
- To analyse the gaps between the Baseline and Target Information System Architectures
- It is important to note that this effort is not concerned with database design
- The goal is to define the data entities relevant to the enterprise, not to design logical or physical storage systems.
- It is important that this effort is not concerned with applications systems design.
- The goal is to define what kinds of application systems are relevant to the enterprise, and what those applications need to do in order to manage data and to present information to the human and computer actors in the enterprise.
- The applications are not described as computer systems, but as logical groups of capabilities that manage the data objects in the Data Architecture and support the business functions in the Business Architecture.
14
Q
The objectives of the Technology Architecture Phase (D) are …
A
- Develop the Target Technology Architecture that enables the Architecture Vision, target business, data, and application building blocks to be delivered through technology components and technology services, in a way that addresses the Statement of Architecture Work and stakeholder concerns
- Identify candidate Architecture Roadmap components based upon gaps between the Baseline and Target Technology Architectures
15
Q
The activities of the Technology Architecture Phase (D) are …
A
- to describe the Baseline Technology Architecture
to develop a Target Technology Architecture by mapping the application components defined in the Application Architecture phase into a set of technology components, which represent software and hardware components, available from the market or configured within the organization into technology platforms - to analyze the gaps between the Baseline and Target Technology Architectures
- Technology Architecture will define baseline and target views of the technology portfolio to address the stakeholders concerns.
- Technology Architecture completes the set of architectural information and therefore supports cost assessment for particular migration scenarios.
