Introduction Flashcards
High-level introduction to the key concepts of Enterprise Architecture
The Open Group
It is a global consortium that enables the achievement of business objectives through technology standard.
The Open Group Vision
Boundaryless (boundaries are permeable) Information flow:
Achieved through global interoperability
In a secure, reliable and timely manner
Architecture Forum - Mission
to advance The Open Group vision of Boundaryless Information flow, for and between enterprises.
What is an Enterprise?
A collection of organizations that share a common set of goals.
What is an Architecture?
It is a fundamental concepts or properties of a system in its environment embodied in - Its elements, Their relation to other environment, Principles governing its design and evolution.
What is Enterprise Architecture?
- The organizing logic for Business processes and IT infrastructure reflecting the integration and standardization requirements of the firms operating model.
- A conceptual blueprint that defines the structure and operation of an organization.
Architecture Domains of TOGAF
- Business Architecture
- Application Architecture
- Data Architecture
- Technology Architecture
What is an Architectural Framework?
A conceptual structure used to develop, implement, govern, and sustain an architecture.
It is a foundational structure, or set of structures, which can be used for developing a broad range of different architectures.
TOGAF Components
- TOGAF Architecture Development Method (ADM)
- ADM guidelines and techniques
- TOGAF Architectural Content Framework
- Enterprise Continuum
- TOGAF Capability Framework
- TOGAF library
ADM
An iterative sequence of steps to develop an enterprise-wide architecture
ADM Guidelines and Techniques
Guidelines and Techniques to support the application of ADM
Architectural Content Framework
A detailed model of Architectural work products, including deliverables, artifacts within deliverables, and the Architecture Building Blocks (ABBs) that deliverables present.
The Enterprise Continuum
A model for structuring a virtual repository and methods for classifying architecture and solution artifacts (ABBs and SBBs).
It is a “framework within a framework”.
The Architecture Capability Framework
A structured definition of the organizations, skills, roles and responsibilities to establish and operate an Enterprise Architecture.
TOGAF library
Reference library containing guidelines, templates, patterns, and other forms of reference material to accelerate the creation of new EA.
ADM Governance repository contains
- Reference data
- Process Status
- Audit information
TOGAF ADM
Describes the process of developing an enterprise-specific arch. by adopting and adapting generic arch. and solutions.
Tools in Enterprise Continuum
Needed to manage and control the artifacts within Enterprise Continuum
Promotes reuse
Enables sharing arch. information with org.
Facilitates easier maintenance of arch.
Ensures common terminology is used
Provides stakeholders with relevant models.
