Section 1 - The ADM Flashcards
Understand the ADM cycle (187 cards)
What is the definition of an Enterprise
“Highest level of description for an organisation”
or
depends on where you work, you need to know your scope before you start
What is TOGAF 9.2 definition of Architecture?
“The structure of components, their inter-relationships, and the principles and guidelines governing their design and evolution over time.”
What is ISO/IEC/!EEE 42010:2011 framework standard?0
“The fundamental concepts or properties of a system in its environment embodied in its element, relationships, and in the principles of its design and evolution.”
What is Architecture?
An architecture is the components of a system and their relationship
AND
the principles governing their design and evolution over time.
What are the 7 core concepts of TOGAF 9.2
1) Defininition of enterprise
2) Architecture Domains, or BDAT
3) Architecture development method, or ADM
4) Deliverables, artifacts and building blocks
5) Enterprise Continuum
6) Architecture repository
7) Defining architecture capability
What are the 4 Architect domains?
1) Business
2) Data
3) Application
4) Technology
What architecture domains deals with defining the current and future capabilities of a business?
Business
What architecture domains deals with defining the current and future structure and interaction of the enterprise’s major types and sources of data?
Data
What architecture domains deals with defining the current and future structure and interaction of the enterprise’s major types and sources of data?
Application
What architecture domains deals with defining the current and future structure and interaction of the technology services and technology components?
Technology
Phases of ADM
(Architecture Development Methods)
The TOGAF Architecture Development Method (ADM) has 13 phases:
Preliminary Phase: Establish a framework for the company’s architecture capabilities, and determine the necessary changes and their implementation
Phase A: Architecture Vision: Define the scope of architecture development, establish an architecture vision, identify stakeholders, and seek approval to proceed
Phase B: Business Architecture: Assess the business architecture
Phase C: Information Systems Architectures: Develop information systems architectures
Phase D: Technology Architecture: Develop technology architecture, and analyze the gaps between the as-is and to-be baseline
Phase E: Opportunities and Solutions: Identify major implementation projects
Phase F: Migration Planning: Analyze the costs, benefits, and risks, and produce an implementation roadmap
Phase G: Implementation Governance: Manage implementation governance
Phase H: Architecture Change Management: Manage architecture change management
Examples of types artifacts
1) Lists
2) Matrices
3) Diagrams
Definition of Deliverables
“Contractually specified and in turn formally reviewed, agreed, and signed off by the stakeholders”
What are Architecture Building Blocks (ABBs)
Named concepts that can be reused in other places. Capabilities
Eg, Look up customers details
What are solution Building blocks (SBB)s
Associated with what is required to fulfill the capability (Eg, Software, people, IT team, cables, building)
Eg,CRM customer search module
What is the Enterprise Continuum?
Away to Classify items in the architecture from extremely generic to extremely specific.
What are the 4 different types of Architectures?
1) Foundation - applies to all companies
2) Common systems - Not all companies but not industry specific
3) Industry - specific to a particular industry
4) Organisation specific - business goals and objectives
What does an Architecture repository contain?
Metamodel
Capability
Landscape
Standard Library (formerly (Standard Information Base (SIB)
Reference Library
Governance Repository (formerly governance log)
Architecture requirements repository (new in version 9.2)
Solutions Landscape (new in version 9.2)
What is a Architecture repository?
Central storage for important architecture documents throughout the project. This should be classified.
What is the purpose of the preliminary phase?
To define and establish your architecture capability including architecture principles.
What questions should we ask in the preliminary phase?
Where
What
Why
and how we do architecture
What are the inputs to the Preliminary phase
- TOGAF Library
- Other architecture frameworks
- Board strategies and business / IT plans and principles, goals
- Major frameworks operating in the business (eg, SCRUM)
- Governance and legal frameworks
- Architecture capability
- Partnership and contract agreements
- Existing documents relating to Architecture capability
- Organisational model of enterprise architecture
- Existing architecture framework
What are the steps to Preliminary phase?
- Scope the enterprise organisation impacted
- Confirm governance and support frameworks
- Define and establish architecture team
- Identify and establish architecture principles
- Tailor TOGAF and other frameworks
- Implement architecture tools
What are the Outputs from Preliminary phase?
- Organisation Model for Enterprise Architecture
- Tailored Architecture Framework
- Initial Architecture Repository
- Business principles, business goals and business drivers
- Request for Architecture Wor (Optional)
- Architecture Governance
