What is an Enterprise
any collection of organizations that has common goals
Architecture
The fundamental concepts or properties of a system in its environment embodied in its
elements, relationships, and in the principles of its design and evolution
Purpose of Enterprise Architecture
to optimize across the enterprise the often fragmented legacy of processes into an
integrated environment that is responsive to change and supportive of the delivery of
the business strategy
Advantages that result from a good Enterprise Architecture
More effective and efficient business operations
More effective and efficient Digital Transformation and IT operations
Better return on existing investment, reduced risk for future investment
Faster, simpler, and cheaper procurement
Architecture Framework
a foundational structure or set of structures, that can be used for developing a broad
range of different architectures
Why do we need a framework
to speed up and simplify architecture development, ensure more complete coverage of
the designed solution, and make certain that the architecture selected allows for future
growth in response to the needs of the business
Why is the TOGAF standard a suitable as a Framework
enables the organization to build workable and economic solutions which address their
business issues and needs
Domains that TOGAF deals with
Business, Data, Application, and Technology
Phases of ADM
Preliminary
Phase A: Architecture Vision
Phase B: Business Architecture
Phase C: Information Systems Architecture
Phase D: Technology Architecture
Phase E: Opportunities and Solutions
Phase F: Migration Planning
Phase G: Implementation Governance
Phase H: Architecture Change Management
Requirements Management
Deliverable
a work product that is contractually specified and in turn formally reviewed, agreed, and
signed off by stakeholders
Artifact
an architecture work product that describes an aspect of the architecture
, Building block
represents a (potentially reusable) components of business, IT, or architectural
capability that can be combined with other building blocks to deliver architecture and
solutions
Architecture building blocks (ABB)
typically describe the required capability
Solution Building Blocks (SBB)
represents the components to be used to implement the required capability
Enterprise Continuum
a view of the Architecture Repository that provides methods for classifying architecture
and solution artifacts as the evolve from generic Foundation Architectures to
Organization Specific Architectures
Architecture Repository
stores different classes of architectural output at different levels of abstraction, created
by the ADM
Major Components of an Architecture Respository
* Architecture Metamodel
* Capability, Landscape
* Stands Information Base (SIB)
* Reference Library
* Governance Tag
* Requirements Repository
* Solutions Landscape
Architecture Metamodel
describes the organizationally tailored application of an architecture framework
Architecture Capability
defines the parameters, structures, and processes that support the governance of the
repository
Architecture Landscape
shows an architectural view of the building blocks that are in use within the org today
Standards Information Base (SIB)
captures the standards with which new architectures must comply
Reference Library
provides guidelines, templates, patterns, and other forms of reference material that can
be leveraged in order to accelerate the creation of new architectures
Governance Log
provides a record of governance activity across the enterprise
Architecture Requirements Repository
provides a view of all authorized architecture requirements which have been agreed
with the Architecture board
Solutions Landscape
presents an architectural representation of the SBB's supporting the Architecture
landscape which have been planned or deployed by the enterprise
Architecture Capability Framework
Establishing an Architecture Capability
Architecture Board
