D - Technology Architecture
Objectives
Develop the Target Technology Architecture
enables
physical
logical
data components
Architecture Vision
Identify candidate Architecture Roadmap components
based upon gaps
between
Baseline Technology Architectures
Target Technology Architectures
Outputs
Statement of Architecture Work
Validated technology principles
Draft Architecture Requirements Specification
Gap Analysis results
• Updated technology requirements
Draft Architecture Definition Document
Views corresponding to the selected viewpoints addressing key
stakeholder concerns
Target Technology Architecture
Environments and locations
{development, production}
Technology platforms and their decomposition
Technology components and their relationships to information
systems
Expected processing load and distribution of load across technology components
Physical (network) communications
Hardware and network specifications
Baseline Technology Architecture
Technology Architecture components of an Architecture Roadmap
Steps
Select reference models, viewpoints, and tools
Description
Select relevant Technology Architecture
resources
(reference models, patterns, etc.)
on the basis of the
business driver
s,
stakeholders,
and their concerns
Technology Architecture
viewpoints
enable the architect to demonstrate how the stakeholder concerns are being addressed in the Technology Architecture.
Identify appropriate
tools and techniques
used for the capture, modeling, and analysis, in
association with the selected viewpoints
Determine the Overall Modeling Process
For each
viewpoint
, select the
models needed
to support the specific view required
Identify Required Catalogs, Matrices, and Diagrams
Technology Architecture should create
technology catalogs
Based on
existing technology catalogs
and the
analysis
of applications carried out in the
Application Architecture phase
, collect a list of
products in use.
extend the product list
by examining products that provide the required functionality and meet the required standards
Classify products
against the
TOGAF TRM
if appropriate
If technology standards are currently in place, apply these to the technology component catalog to gain a baseline view of compliance with technology standards.
Catalogs
Technology Standards catalog
Technology Portfolio catalog
Matrices
Application/Technology matrix
Diagrams
Environments and Locations diagram
Platform Decomposition diagram
Processing diagram
Networked Computing/Hardware diagram
Communications Engineering diagram
Identify Types of Requirements to be Collected
Select Services
services portfolios are combinations of
basic services from the
service categories in the TOGAF TRM
that do not conflict
For each building block
build up a service description portfolio as a set of
non-conflicting services
Develop Baseline Technology Architecture Description
existing technology components are likely to be carried over into the Target Technology
Begin by converting the description of the existing environment into the terms of the organization’s
Foundation Architecture
(e.g., the TOGAF Foundation Architecture’s TRM ).
Identify the relevant Technology Architecture building blocks
If nothing exists , define each application in line with the Technology Portfolio catalog;
set down a list of key questions
which can be used later in the development process to measure the effectiveness of the new architecture
Develop Target Technology Architecture Description
identify the relevant Technology Architecture
building blocks
A key process in the creation of a broad architectural model
of the target system is the conceptualization of building blocks
Architecture Building Blocks (ABBs) describe the
required functionality and how it may be implemented
without the detail introduced by configuration or detailed design
Perform Gap Analysis
Identify gaps between the baseline and target using
Gap Analysis
Define candidate roadmap components
Th is initial Technology Architecture Roadmap will be used as raw material to support more detailed defi nition of a consolidated, crossdiscipline roadmap within Phase E: Opportunities & Solutions
Resolve impacts across the Architecture Landscape
Have
recent changes been made that impact
the Technology
Architecture?
Does this Technology Architecture impact any
pre-existing architectures
?
Are there any opportunities to
re-use work
from this Technology Architecture in other areas of the organization
Does this Technology Architecture impact other projects (planned or those in progress)
Will this Technology Architecture be impacted by other projects (planned or those in progress)?
Conduct formal stakeholder review
Finalize the Technology Architecture
Select standards for each of the building blocks, re-using
Fully document each building block
Finalize all the work products
Create Architecture Defi nition Document
Catalogs
inventories of the core assets of the business
hierarchical in nature
capture the decomposition of a metamodel entity
decompositions across related model entities
