Do Agile, EA and TOGAF Relate?
Do Agile, EA and TOGAF Overlap?
Copyright 2015 ITpreneurs. All rights reserved.The TOGAF Approach to Enterprise ArchitectureCopyright 2015 ITpreneurs. All rights reserved.Enterprise Architecture (EA)Those properties of a thing and its environment that are necessary and sufficient for it to be fit for purpose for its mission (L. Fehskens)Managing the execution of the corporate strategy (J. Scott)
Fundamental concepts or properties of a system in its environment embodied in its elements, relationships, and in the principles of its design and evolution(ISO/IEC 42010)
Copyright 2015 ITpreneurs. All rights reserved.
EA aligns strategy to operations, and business demand to IT supply, ensuring changes are in line with strategy and goals
Enterprise Architecture provides insight into the current and desired state of the organization, information systems and technology
EA improves quality of individual solutions, simplifies their development and maintenance, and prolonging their life time

All rights reserved.Manifesto for Agile Software DevelopmentWe are uncovering better ways of developingsoftware by doing it and helping others do it.Through this work we have come to value:Individuals and interactions over processes and toolsWorking software over comprehensive documentationCustomer collaboration over contract negotiationResponding to change over following a planThat is, while there is value in the items onthe right, we value the items on the left more.
Copyright 2015 ITpreneurs. All rights reserved.Principles behind the agile manifestoOur highest priority is to satisfy the customer through early and continuous delivery of valuable software.Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage.Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.Business people and developers must work together daily throughout the project.Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.Working software is the primary measure of progress.Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.Continuous attention to technical excellence and good design enhances agility.Simplicity--the art of maximizing the amount of work not done--is essential.The best architectures, requirements, and designs emerge from self-organizing teams.At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.

Chief architect- coordinates work on high-level architectural issues that cut across multiple systems- reviews development of new systems to make sure they avoid common mistakes, and that they are aligned with architectural vision- the feedback is always just suggestions and input - the decision for the final design of the system still lies with the squad building it
