2. TOGAF is an architecture framework that provides
the methods and tools for assisting in the
acceptance, production, use, and maintenance of an
enterprise architecture. It is based on an iterative
process model supported by best practices and a
reusable set of existing architecture assets.

3.  The Business Architecture defines the business
strategy, governance, organization, and key
business processes.
 The Application Architecture provides a blueprint
for the individual applications to be deployed, their
interactions and their relationships to the core
business processes of the organization.

4.  The Data Architecture describes the structure of
an organization’s logical and physical data assets
and data management resources.
 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.

6. Preliminary Phase
describes the preparation
and initiation activities required
to create an Architecture
Capability including
customization of TOGAF and
definition of Architecture
Principles.

16. Deliverables  a contractually specified work product.
Artifacts  a more granular architectural work product
describing an architecture from a specific viewpoint.
Building blocks  representing a (potentially reusable)
component of business, IT, or architectural capability.
 Architecture Building Blocks (ABBs) describe required
capability.
 Solution Building Blocks (SBBs) represent components
that will be used to implement the required capability.

20. According to TOGAF, architecture principles define
“the underlying general rules and guidelines for the use
and deployment of all IT resources and assets across the
enterprise”
(TOGAF http://www.opengroup.org/architecture/togaf8-doc/arch/chap29.html)

21. Principles governing the architecture process, affecting:
 development
 maintenance
 use
of enterprise architecture
Principles governing the implementation of the architecture,
establishing:
 first tenets
 related guidance
for designing and developing information systems

22. Name: Should both represent the essence of the rule as well as be
easy to remember.
Statement: Should succinctly and unambiguously communicate the
fundamental rule.
„Rationale: Should highlight the business benefits of adhering to the
principle, using business terminology.
Implications: Should highlight the requirements, both for the business
and IT, for carrying out the principle - in terms of resources, costs,
and activities/tasks.
Name
Statement
Rationale
Implications
Schema:

23.  Don’t mention specific technology platforms in the Name
or Statement of a principle.
 Avoid ambiguous words in the Name and in the
Statement such as: "support", "open", "consider", and
for lack of good measure the word "avoid", itself.
 Be careful with "manage(ment)”.
 Look for and avoid unnecessary adjectives and adverbs
(fluff).

24.  Point to similarity of information and technology principles.
 Point to principles governing business operations.
 Describe relationship to other principles and the intentions
regarding a balanced interpretation.
 Describe situations where one principle would be given
precedence or carry more weight than another for making
a decision.

25. Name Interoperability
Statement All the software in university (already existed and new developed)
should conform the same standards either in technologies or
interface.
Rationale Keeping existed software standards let spend minimum time and
costs for development.
Hardware and data standards prevent reiterative appeals or
applications for explaining usage or operations.
In the general will improve satisfaction of users and clients.
Implications Interoperability standards will be followed unless client (university)
would like completely change an inner software or hardware
environment. All the hardware should exist in minimum variety of
kinds. Investigate data formats, as the transcribed data should
arouse minimal amount of problems by opening in any kind of
software environment.

43.  TOGAF provides an abstract framework that can be
tailored or enhanced for every kind of enterprise
 The Open Group pointed out three aspects to tailor:
• Terminology
o Architecture practitioners should use terminology that is
generally understood
• Process
o Provides the opportunity to remove, add and change
tasks of the ADM
• Content
o Allows adoption of third-party content frameworks
o Allows customization of the framework to support
organization-specific requirements

44. Modelling notations for different levels of abstraction and for
specific aspects
 Organisational modelling
o Organisational diagram
(MS Visio®)
o Work environment diagram
(ADONIS®)

45.  Represent the structure of an organisation, the distribution
of work and hence the responsibilities
 Useful for work assignments and for access rights
o Understanding of business domains and organisational
units involved
o Workflow management systems
o Coordinating the assignment and workload to personnel
and the need for respective systems applications for
their work
o Access control at systems level

46.  In general they describe the overall structure of an
organization and further on the human actors involved in a
process
 Approach: Organisational diagrams describing
• The individual organisational units and the relationship
among different such units
o Including hierarchical relations such as Headquarter
-> Business domain -> Department -> Group -
> Position
o Concept of decomposition
• Smallest unit in organisational diagrams is position

66.  Identify business goals, business drivers of the organisation
• May be defined elsewhere in the enterprise
o If yes: ensure that the existing definitions are up to
date, and clarify any areas of ambiguity
 Define constraints that must be dealt with
• project-specific constraints (time, schedule, resources,
etc.)
• enterprise-wide constraints (by the business and
architecture principles)
 Work with originators of the Statement of Architecture Work
and Corporate Management to secure their endorsement.

67.  Define what is inside and what is outside the scope of
the Baseline Architecture and Target Architecture efforts
• Often Baseline is described on higher level of
abstraction to save time and capabilities for more
detailed Target description
 TOGAF requests to define:
• The breadth of coverage of the enterprise
• The level of detail required
• The partitioning characteristics of the architecture
• The specific architecture domains to be covered
(business, data, application, technology)
• The extent of the time period
• The architectural assets to be leveraged, or considered
for use

68.  Review the principles under which the architecture is to be
developed
• normally based on the principles developed as part of
the Preliminary phase
 Ensure that the existing definitions are current, and clarify
any areas of ambiguity
 Work with responsible for Architecture Governance and
corporate management to secure their endorsement

69.  Create a high-level view of the Baseline and Target
Architectures based on:
• Stakeholders concerns
• Business capabilities requirements
• Scope
• Constraints and principles
 TOGAF states Business scenarios as useful technique

70.  Business scenario is a method for:
• identifying and articulating the business and architecture
requirements
 Method may be used iteratively and at different levels of
detail
 Business scenario describes
• A business process, application, or set of applications
that can be enabled by the architecture
• The business and technology environment
• The people and computing components (called
"actors") who execute the scenario
• The desired outcome of proper execution

71.  Identifying, documenting, and ranking the problem driving
the scenario
 Identifying the business and technical environment of the
scenario and documenting it in scenario models
 Identifying and documenting desired objectives
• Get "SMART“

72. A good business scenario is "SMART"
 Specific, by defining what needs to be done in the
business
 Measurable, through clear metrics for success
 Actionable, by
• Clearly segmenting the problem
• Providing the basis for determining elements and plans
for the solution
 Realistic, in that the problem can be solved within the
bounds of physical reality, time, and cost constraints
 Time-bound, in that there is a clear statement of when
the solution opportunity expires

73.  Identifying the human actors (participants) and their place
in the business model
 Identifying computer actors (computing elements) and their
place in the technology model
 Identifying and documenting roles, responsibilities, and
measures of success per actor; documenting the required
scripts per actor, and the results of handling the situation
 Checking for "fitness-for-purpose" and refining only if
necessary

74. 1. • Problem
2. • Environment
3. • Objectives
4. • Human Actors
5. • Computer Actors
6. • Roles & Responsibilities
7. • Refine

75. Digging into details through iterative phases of Gathering, Analyzing
and Reviewing

76.  Gathering is the phase where information is collected
• Multiple techniques to solve this phase
o Desk research to investigate Information
o Surveys
o Workshop with carefully selected participants from
high levels in business and technical positions
 Enterprise Architect can strengthen the business scenario
by obtaining "real-world examples"

77.  Information gathered is processed and documented
 Further models are created to represent that information
 Maintain linkages between the key elements of the
business scenario
• Creation of matrices that assist in maintaining such
linkages
o Constituencies
o Human Actors
o Computer Actors
o Issues
o Objectives

78.  Feedback results to the contractor of the project to ensure
that there is a shared understanding of:
o the full scope of the problem
o and the potential depth of the technical impact.
 Interactive workshops are an appropriate way to
communicate the results
 Key sensitive feature
o Absence of shared expectations in many cases the
background of latter project failures
