Enterprise architecture is 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. ANSI/IEEE Std 1471-2000
Enterprise architecture could be revised from four points-of-view, called the business perspective, the application perspective, the information perspective, and the technology perspective. The business perspective defines the processes and standards by which the business operates on a day-to-day basis. The application perspective defines the interactions among the processes and standards used by the organization. The information perspective defines and classifies the raw data (such as document files, databases, images, presentations, and spreadsheets) that the organization requires in order to efficiently operate. The technology perspective defines the hardware, operating systems, programming, and networking solutions used by the organization. Michael Platt (Microsoft)
Effective management and exploitation of information through IT is key to business success
Good information management = competitive advantage
Current IT systems do not really meet the needs of business
o Fragmented, duplicated o Poorly understood o Not responsive to change
Investment in Information Technology o Focused on system maintenance o Tactical developments rather than a strategic plan
It helps an organization achieve its business strategy Faster time to market for new innovations and capabilities More consistent business processes and information across business units More reliability and security, less risk
A more efficient business operation A more efficient IT operation Better return on existing investment, Reduced risk for future investment Faster, simpler, and cheaper procurement
The enterprise's high-level objectives and goals. The business processes carried out by the entire enterprise, or a significant portion of the enterprise. The business functions performed. Major organizational structures. The relationships between these elements.
Descriptions of automated services that support the business processes. Descriptions of the interaction and interdependencies (interfaces) of the organization's application systems. Plans for developing new applications and revising old applications based on the enterprises objectives, goals, and evolving technology platforms.
Standard data models. Data management policies. Descriptions of the patterns of information production and consumption in the organization.

Understand and learn how to facilitate system and network management.
Improves the ability to address critical enterprise-wide issues like security, data protection and etc. Eases upgrade and exchange of system components.
Better return on existing investment reduces risks for future investments through
Reduced complexity in IT infrastructure
Maximum return on investment in existing IT infrastructure Flexibility to make, buy, or out-source IT solutions
educed risk overall R in new investment and in the costs of IT ownership.
Acquire the fundamental skills and means to govern the strategic, process and technology aspects along a coherent IT strategy for an organisation to support business alignment.
Enterprise Architecture is understood as an approach to model complex systems From different views On several levels

Zachman framework: 1987
ADONIS reference model: mid 1990s
Microsoft Solutions Framework: 1994
TOGAF (The Open Group Architecture Framework): 1995
Named by John A. Zachman Zachman worked about 26 years
as CEO for IBM
Released the first Zachman framework in 1987 (adopted several times until today) Basis for today's Enterprise Architecture Frameworks e.g. FEAF Zachman framework offers a frame for modelling an enterprise from different viewpoints and levels of abstraction It also provides links between these viewpoints and levels of abstraction
What
How Where
data, documents
Example: Product, service functions, processes
Example: Order product, ship product, issue invoice
organisation, organisations networks Example: Sales department, dispatching, accounting
Who
When Why
roles, persons
Example: Dispatcher, Sales person, accountant chronology, trigger, results
Example: Order placed, product dispatched, invoice issued
motivation, organisational aims/strategy, organisations environment, rules Example: Sell product, make benefit, satisfy customer, ensure fast delivery of product
Planner
Owner Designer
Objectives/Scope Aims, systems environment Conceptual Enterprise model Logical System model Physical Technical model Implementation Representation Enterprise Sample models

Subcontractor User
A grid to structure complex content Each viewpoint for each target group requires unique types of models Zachman framework provides a frame for WHAT needs to be analysed and conceptualised It does not offer methodology to develop the models
tools to generate models
BOC was established in 1995 B OC is a spin-off from the BPMS Group of the University of Vienna BOC provides tools for Business Process Management, IT Management and Strategy Management
Business Process Management Systems: Strategy model Process landscape Business process model Further models: EPC model
Organisation model
Work environment model UML:
Resource model
Enhanced Business Process model (Security)
Use case model
Activity model Class diagram
Role model
Key indicator model
ADONIS is a toolset for business process management and enterprise management Offers a range of notations for different models. Links different concepts, views and layers of the Zachman framework. Provides support in the documentation of models. More detailed than the Zachman framework
Complementary to e.g. TOGAF by providing a tool support (partial support for the pathway from the analysis to the technical implementation).
The Open Group is a vendor-neutral and technology-neutral consortium, whose vision of Boundary-less Information Flow will enable access to integrated information, within and among enterprises, based on open standards and global interoperability. (http://www.opengroup.org/). The open group contains about 300 organisations e.g. Capgemini, Fujitsu, HP, IBM, NEC, US Department of Defense, NASA, Sun Microsystems. The Open Group is operating as not-for-profit', since about 20 years. 47% of members come from North America, 34% from Europe, 12% from Asia-Pacific, and 7% from the Middle East and Africa.
The first version of TOGAF, developed in 1995, was based on the US Department of Defenses Technical Architecture Framework for Information Management (TAFIM). The first seven versions of TOGAF addressed technology architecture based on the adoption of architecture in businesses at the time each was written
In 2002, Version 8 (the Enterprise Edition) was published
Followed by improvements as Version 8.1 in 2003 and Version 8.1.1 in 2006.
The actual version 9 of the TOGAF Framework was released in 2009.
TOGAF offers a methodology to develop Enterprise Architecture. Further a framework to structure and relate created models.
Provides an abstract frame which can be filled with toolkits like ADONIS. TOGAF provides an abstract methodology HOW and covers the WHAT in details. for the

You are an Enterprise Architect working for SAP, Cap Gemini, Cisco, Bearingpoint, etc.
Your organization requests you to conceptualize and implement a new social system oriented both on academicians and students, their parents for a National Ministry of Science and Education. End-consumer is your home university.
The Client asks you to come up with an offer for analysing, specifying, designing, implementing and deploying an innovative social platform, which would be integrated in the existing university system, proposing smart and fully automated interactions among actors without breaks.
Element
Include structure
Comment
Include only enough structure to allow you to record the process and concerns. The latter requires that all the people who will use or could conceivably be affected by the introduction of the new system be included. Do not attempt to record all the intricacies of process; a broad brush approach is usually all that is needed.
Caricature the concern in a thought bubble. A fuller explanation may be provided in a supplementary document. This will make the rich picture comprehensible to your informants.
Include process
Include concerns
Use the language of the people depicted in it
Use any pictorial or textual device that suits your purpose
There is no correct way of drawing a rich picture. There are as many styles as analysts and the same analyst will find different styles useful in different situations.
