  2. 2. 81% Line of business workers and 83% of IT Staff admit to using non approved SAAS apps 42% IT Suppliers increasingly target business users 42% Line of Business heads demand higher velocity for IT Projects 36% Line of Business heads are more tech savvy and drive their own IT Projects 34% Line of Business owners are able to access technology more easily Reference: IDC CIO Summit, 2014, CIOInsight

  5. 5. An architecture framework is a foundational structure, or set of structures, which can be used for developing a broad range of different architectures. It should describe a method for designing a target state of the enterprise in terms of a set of building blocks, and for showing how the building blocks fit together. It should contain a set of tools and provide a common vocabulary. It should also include a list of recommended standards and compliant products that can be used to implement the building blocks. Reference: TOGAF
  6. 6. 7 “A well-defined practice for conducting enterprise analysis, design, planning, and implementation, using a holistic approach at all times, for the successful development and execution of strategy. Enterprise architecture applies architecture principles and practices to guide organizations through the business, information, process, and technology changes necessary to execute their strategy” Reference: Wikipedia
  7. 7. 8 Information and Technology definition “EA is explicitly describing an organization through a set of independent, non-redundant artifacts, defining how these artifacts interrelate with each other, and developing a set of prioritized, aligned initiatives and roadmaps to understand the organization, communicate this understanding to stakeholders and move the organization forward to its desired state” Business definition “EA illuminates how an organization and all of its members can achieve its objectives, through the creation of a series of engineered models and project initiatives, that can be easily understood by all the people associated with the organization” Reference: John Zachman EA Presentation
