Defining an IT Architecture TOGAF - The Continuing Story Defining an IT Architecture ANSI/IEEE Standard 1471-2000 Conceptually an IT 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. Practically it is represented in Architectural Descriptions from the viewpoints of the Stakeholders TOGAF - The Continuing Story of 49 TA P12 Version 1.0 01/03

Some more ANSI/IEEE definitions TOGAF - The Continuing Story Some more ANSI/IEEE definitions Architect: the person, team, or organisation responsible for systems architecture Architecting: the activities of defining, documenting, maintaining, improving and certifying proper implementation of an architecture. Architectural description a collection of products to document an architecture. TOGAF - The Continuing Story of 49 TA P12 Version 1.0 01/03

Architecture views - definitions TOGAF - The Continuing Story Architecture views - definitions System Stakeholder: an individual, team, or organization (or classes thereof) with interests in, or concerns relative to, a system View: a representation of a whole system from the perspective of a related set of concerns Viewpoint: (a schema of the information in a view) acts as a pattern or template from which to develop individual views by establishing the purposes and audience for a view and the techniques for its creation and analysis TOGAF - The Continuing Story of 49 TA P12 Version 1.0 01/03

TOGAF - The Continuing Story Architecture view Description of the architecture from the viewpoint of a specific stakeholder The main mechanism of communication between the architect and the stakeholder Used to ensure accuracy of understanding of the current system Used to ensure the architecture meets the need of each stakeholder The collection of views comprises the description of the architecture TOGAF - The Continuing Story of 49 TA P12 Version 1.0 01/03

TOGAF - The Continuing Story Architecture We are NOT talking about rocket science We ARE talking about: Using common sense Being systematic Avoiding misunderstandings Knowing what we are doing before we start Knowing why we are doing it Learning from the best practice of others Treating the user as a partner Talking to business users in business terms Recording what, where, when, how, who and WHY TOGAF - The Continuing Story of 49 TA P12 Version 1.0 01/03

What is an Enterprise Architecture? TOGAF - The Continuing Story What is an Enterprise Architecture? An Enterprise Architecture is the technical foundation of an effective IT strategy It consists of four types of architecture: Business architecture Information system architectures Data or information architecture Application architecture Technology architecture All these are related TOGAF 8 Enterprise Edition TOGAF 7 Technical Edition TOGAF - The Continuing Story of 49 TA P12 Version 1.0 01/03

What is the desired benefit of TOGAF? TOGAF - The Continuing Story What is the desired benefit of TOGAF? Architected business information systems will have: A greater ability to respond to new demands A greater business value to the organization A greater ability to use new technology A faster, simpler and cheaper procurement process The ability to support a faster time-to-market Can a business succeed without a documented business plan? Can IT succeed without a documented architecture? TOGAF - The Continuing Story of 49 TA P12 Version 1.0 01/03

What is an Architectural Framework? TOGAF - The Continuing Story What is an Architectural Framework? Architecture design is a complex process An architectural framework is a tool for: Designing a broad range of a architectures Assisting the evaluation of different architectures Selecting and building the right architecture for an organization It embodies best practice and acknowledged wisdom It presents a set of services, standards, design concepts, components and configurations It guides the development of specific architectures TOGAF - The Continuing Story of 49 TA P12 Version 1.0 01/03

What is an Architectural Framework? TOGAF - The Continuing Story What is an Architectural Framework? Use of a framework leads to: The use of common principles, assumptions and terminology The development of information systems with better integration and interoperability, especially with respect to issues that affect the whole enterprise WARNING!
