  • What is Architecture?

    u ISO/IEC 42010:2007 defines "architecture" as:u "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.

    u In TOGAF, "architecture" has two meanings depending upon the context:u A formal description of a system, or a detailed plan of the system at component

    level to guide its implementation

    u The structure of components, their inter-relationships, and the principles and guidelines governing their design and evolution over time

  • What is Enterprise Architecture

    Enterprise architecture (EA) is the process of translating business vision and strategy into effective enterprise

    change by creating, communicating, and improving the key principles and models that describe the enterprises future state and enable its evolution.

    A conceptual blueprint that defines the structure and operation of an organization. The intent of an enterprise architecture is to determine how an

    organization can most effectively achieve it's current and future objectives.

  • Enterprise Architecture?What !!!!!

    Mohamed Sami - https://melsatar.blog/

  • The Anatomy of a City

    u The City architecture has a lot of layersu What if we need to transform this city into a smarter

    city?u What if we need to upgrade the utility services?u What if we need to have a big change in the city

  • Do we need the city blueprint?

    body?do we need the

    schematics of a car?

  • What is the value?

    Mohamed Sami - https://melsatar.blog/

  • Value of Enterprise Architecture

    Efficient business


    Efficient IT operation

    Reduced risk for future


    Faster, simpler, and

    cheaper procurement

    Increase Business

    Continuity and Agility

    Better optimization of resources

    and eliminate duplication

    Mohamed Sami - https://melsatar.blog/

  • What is the real problem?Business and IT Alignment !!

    Mohamed Sami - https://melsatar.blog/

  • How can we solve that?

    u Using common vocabularyu Visualizing the concerns from stakeholders perspectivesu Establishing the language that all can understand

    Having a framework

    Mohamed Sami - https://melsatar.blog/

  • We need clear steps to be able to solve this puzzle

    Mohamed Sami - https://melsatar.blog/

  • What is the architecture framework?

    is a tool that can be used for developing a broad range of different architectures.

    u It should describe a method for designing an information system in terms of a set of building blocks, and for showing how the building blocks fit together.

    u It should contain a set of tools and provide a common vocabulary.

    u It should also include a list of recommended standards and compliant products that can be used to implement the building blocks.

  • What is the value?

    Mohamed Sami - https://melsatar.blog/

  • The framework value

    Provides a practical starting point for an Architecture Project

    u Avoids the initial panic when the scale of the task becomes


    u Systematic Codified common sense

    u Captures what others have found to work in real life

    u Contains a Baseline set of resources for reuse

  • What is TOGAF?

    u TOGAF is an architecture framework The Open Group Architecture Framework. TOGAF is a tool for assisting in the acceptance, production, use, and maintenance of enterprise architectures. It is based on an iterative process model supported by best practices and a re-usable set of existing architectural assets.
