3. • Provide a clear view of how the business and technology resource will
support and achieve an organisation's business goals and initiatives
• Understand the strategy, the business, the systems and the
infrastructure and how they interrelate.
• Moving “ need to know” information to those that “know the need”
upstream and down stream and in both directions.
• Help us prioritise and decide which things to do and in what order
• “Doing the Right Things”
• Governance the change and building of things
• “Doing the Things Right”

5. • TOGAF is a framework for enterprise architecture which provide
comprehensive approach for:
• Designing
• Planning
• Implementing
• Governing
• Enterprise Architecture
“The organisation logic of business processes and IT infrastructure reflecting the
integration and standardisation requirements of firm’s operating model” – MIT Centre of Information
Systems Research
• Why Enterprise Architecture
Its purpose is optimise across the enterprise the often fragmented legacy of processes
(both manual & automated) into an integrated environment that is responsive to
change and supportive of the delivery of the business strategy.
What is TOGAF?
Leading the development of open, vendor-
neutral IT standards and certifications
6. Types of Architecture in TOGAF
• Business Architecture – defines the business strategy, governance, organization, and key business
processes.
• Data/Information Architecture – describes the structure of an organization's logical and physical
data assets and data management resources.
• Application (System) Architecture – provides a blueprint for the individual applications to be
deployed, their interactions, and their relationships to the core business processes of the organization.
• Information Technology (IT) 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.

Editor's Notes
Enterprise Architecture is a very complex area
Alignment of strategy, business, technology
Processes and systems are non-integrated
EA provide a framework to structure and organise processes, systems and artefacts
Why we need enterprise architecture for Vodafone as a business.
Strategy is a journey from where are you are to where you want to be
Business model: how the business will be operating in ever changing environment with support of your suppliers/partners and business capabilities
