TOGAF Deal With

• The Business Architecture defines the business strategy, governance, organization,

and key business processes.

• The Data Architecture describes the structure of an organization's logical and physical

data assets and data management resources.

• The Application Architecture provides a blueprint for the individual application systems

to be deployed, their interactions, and their relationships to the core business processesof the organization.

• The Technology Architecture describes the logical software and hardware capabilities

that are required to support the deployment of business, data, and application services.This includes IT infrastructure, middleware, networks, communications, processing,standards, etc.

The major components within an rchitecture !epository are as follows"

• The Architecture Metamodel describes the organizationally tailored application of an

architecture framework, including a metamodel for architecture content.

• The Architecture Capability defines the parameters, structures, and processes that

support governance of the rchitecture !epository.

• The Architecture Landscape shows an architectural view of the building blocks that are

in use within the organization today #e.g., a list of the live applications$. The landscape islikely to e%ist at multiple levels of abstraction to suit different architecture objectives.

• The Standards n!ormation Base #&I$ captures the standards with which new

architectures must comply, which may include industry standards, selected products andservices from suppliers, or shared services already deployed within the organization.

• The "e!erence Library provides guidelines, templates, patterns, and other forms of

reference material that can be leveraged in order to accelerate the creation of newarchitectures for the enterprise.

• The Go#ernance Log provides a record of governance activity across the enterprise.

an enterprise architecture practice should establish capabilities in the following areas"

• (inancial )anagement

• *erformance )anagement

• &ervice )anagement

• !isk )anagement

The benefits of architecture governance include"

• Increased transparency of accountability, and informed delegation of authority

• +ontrolled risk management

• *rotection of the e%isting asset base through ma%imizing reuse of e%isting architectural

components

• *roactive control, monitoring, and management mechanisms

• *rocess, concept, and component reuse across all organizational business units

• /alue creation through monitoring, measuring, evaluation, and feedback

• Increased visibility supporting internal processes and e%ternal parties' requirements0 in

particular, increased visibility of decisionmaking at lower levels ensures oversight at anappropriate level within the enterprise of decisions that may have farreaching strategicconsequences for the organization

• 1reater shareholder value0 in particular, enterprise architecture increasingly represents

the core intellectual property of the enterprise studies have demonstrated a correlationbetween increased shareholder value and wellgoverned enterprises

• Integrates with e%isting processes and methodologies and complements functionality by

adding control capabilities

T21( document is categorized according to the following four categories"

• TOGAF Core consists of the fundamental concepts that form the essence of T21(.

• TOGAF Mandated consists of the normative parts of the T21( specification. These

elements of T21( are central to its usage and without them the framework would notbe recognizably T21(. &trong consideration must be given to these elements whenapplying T21(.


3/4

• TOGAF "ecommended consists of a pool of resources that are specifically referenced in

T21( as ways in which the T21( +ore and )andated processes can beaccomplished #e.g., the &-I rchitecture Trade2ff nalysis )ethod or businessscenarios$.

• TOGAF Supporting consists of additional resources that are not referenced in the other

three T21( categories itself but provide valuable assistance.

3hy do I need an enterprise architecture4

• more efficient business operation"

o 5ower business operation costs

o )ore agile organization

o usiness capabilities shared across the organization

o 5ower change management costs

o )ore fle%ible workforce

o Improved business productivity

• more efficient IT operation"

o 5ower software development, support, and maintenance costs

o Increased portability of applications

o Improved interoperability and easier system and network management

o Improved ability to address critical enterprisewide issues like security

o -asier upgrade and e%change of system components

• etter return on e%isting investment, reduced risk for future investment"

o !educed comple%ity in the business and IT

o )a%imum return on investment in e%isting business and IT infrastructure

o The fle%ibility to make, buy, or outsource business and IT solutions

o !educed risk overall in new investments and their cost of ownership

• (aster, simpler, and cheaper procurement"


4/4

o uying decisions are simpler, because the information governing procurement is

readily available in a coherent plan

o The procurement process is faster ma%imizing procurement speed and fle%ibility

without sacrificing architectural coherence

o The ability to procure heterogeneous, multivendor open systems

o The ability to secure more economic capabilities

3hat is an architecture framework4

• n architecture framework is a foundational structure, or set of structures,

• 3hich can be used for developing a broad range of different architectures.

• It should describe a method for designing a target state of the enterprise in terms of a set

of building blocks,

• nd for showing how the building blocks fit together. It should contain a set of tools and

provide a common vocabulary.

• It should also include a list of recommended standards and compliant products that can

be used to implement the building blocks.

3hy do I need T21( as a framework for enterprise architecture4

• T21( has been developed through the collaborative efforts of over 677 rchitecture

(orum member companies from some of the world's leading companies and

organizations.

• 8sing T21( results in enterprise architecture that is consistent, reflects the needs ofstakeholders, employs best practice, and gives due consideration both to current

requirements and the perceived future needs of the business.

• 9eveloping and sustaining an enterprise architecture is a technically comple% process

which involves many stakeholders and decision processes in the organization. T21(

plays an important role in standardizing and derisks the architecture development

process.

• T21( provides a best practice framework for adding value, and enables the

organization to build workable and economic solutions which address their business

issues and needs.
