What is an enterprise in the context of EA?
• Open Group defines "enterprise" as any collection of
organizations that has a common set of goals.
• For example, an enterprise could be a government
agency, a whole corporation, a division of a corporation, a
single department, or a chain of geographically distant
organizations linked together by common goals.

What is architecture is in the context of TOGAF?
• ISO/IEC 42010:2007 defines "architecture" as:
• "The fundamental organization of a system, embodied in its
components, their relationships to each other and the environment,
and the principles governing its design and evolution." TOGAF
embraces but does not strictly adhere to ISO/IEC 42010:2007
terminology.
• In TOGAF, "architecture" has two meanings depending
upon the context:
• A formal description of a system, or a detailed plan of the system
at component level to guide its implementation
• The structure of components, their inter-relationships, and the
principles and guidelines governing their design and evolution

Different types of architecture
• Business Architecture • defines the business strategy,
governance, organization, and key business processes
• Data Architecture • describes the structure of an
organization's logical and physical data assets and data management resources
• Application Architecture • provides a blueprint for the individual
application to be deployed, their interactions, and their relationships to the core business processes of the organization
• 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

Objectives of TOGAF ADM phases
• Determine and establish
the Architecture Capability
• Develop a high-level aspirational vision of the
proposed enterprise architecture
• Obtain approval for a Statement of Architecture
Work
• Develop the Target Business or Data
or Application or Technology
Architecture
• Identify candidate Architecture
Roadmap components
• Generate the initial complete version of
the Architecture Roadmap
• Determine whether an incremental
approach is required
• Finalize the Architecture Roadmap and the
supporting Implementation and Migration Plan
• Ensure conformance with the Target
Architecture by implementation
projects
• Perform appropriate Architecture
Governance functions for the
solution
• Ensure that the architecture lifecycle is maintained
• Ensure that the Architecture Governance
Framework is executed
• Ensure that the enterprise Architecture
Capability meets current requirements
• Ensure that the Implementation and Migration Plan is
coordinated with the enterprise’s overall change
portfolio
• Manage architecture
requirements identified
during any execution of
the ADM cycle or a phase
• Ensure that relevant
architecture requirements
are available for use by
each phase

• IT service management (ITSM)
• The implementation and
management of quality IT services
that meet the needs of the
business
TOGAF
• In TOGAF, "architecture" has
two meanings depending upon
the context:
• A formal description of a system,
or a detailed plan of the system

TOGAF vs ITIL
• ITIL concentrates in IT services that support business services • Planning, developing, implementing, operating and improving
• IT services
• IT service management capability
• Architecture design is one of the service design aspects in ITIL • ITIL refers especially to Data/Information, Application and IT infrastructure
architectures but also to Service and Environmental architectures
• TOGAF concentrates in EA that supports the business goals • Planning, developing, governing the implementation and operation and
improving • Architecture that describes how the enterprise needs to operate to achieve the
business goals
• Architecture Capability
• TOGAF refers to IT Service Management and ITIL • When building Architecture Capability, in Implementation Governance and in
Architecture Change Management
• TOGAF does not go into details of ITSM coordination

TOGAF vs ITIL
• Both are based on best practices
• Both should be tailored for each organization
• Business alignment was added into the later versions of
both frameworks
• Both use Deming Cycle as the method of improvement
• Though it is not specifically mentioned in TOGAF ADM
• ITIL goes much deeper into guiding how continual improvement is
done

Different perspectives
• ITIL concentrates in managing IT services
• Business architecture is not in scope of ITIL
• Business architecture is one of the TOGAF architecture
domains
• Service transition and service operation are part of ITIL
service lifecycle
• Actual solution deployment and operation is not in scope of
