What is Enterprise Architecture?

The Enterprise Architecture represents a link between the enterprise business and IT strategies and the operational systems being developed and executed in production.

The Business Principles are the most important drives that shape and govern the Enterprise Architecture and Solutions built by delivery projects. The Architecture Principles concern the Enterprise Architecture and there will be separate architecture principles for each Architecture Domain (e.g. Business Services, Process Architecture, Information Architecture, Application Architecture and Technology Architecture).

The Vision is a statement of the primary goals and objectives desired in the future.

Application Development projects are normally aimed at fulfilling the business requirements which are themselves part of the target Operating Model, although some tactical projects may be undertaken.

The Target Enterprise Architecture realises a to-be architecture that embodies the target Operating Model, Business and IT strategies, enterprise vision etc. It represents a bridge between the enterprise vision and the application development projects.

Once the work in an application development projects is completed, the solution architecture becomes part of the overall Current Enterprise Architecture models.

  1. Hi Adrian,

    I am an Acquisition Editor at Packt Publishing http://www.packtpub.com. We publish practical and focused IT books on a variety of technologies. We are are currently planning to develop a book on Enterprise architecture.

    We plan to make a 400 page book. you can say it is something similar to Enterprise Architecture Planning: Developing a Blueprint for Data, Applications, and Technology book. This is a very old book and we want to come up with a EA book that highlights the latest technologies available. Looking at your blog I am sure that you are an EA enthusiast.

    This topic seems to have a lot of potential and I would like to know your thoughts. I want to commit this project and look forward to working with you on it. Thank you for considering this request, and I would very much appreciate you letting me know your thoughts about authoring this book. You can write to me at dhwanid@packtpub.com.

    Thanks!
    Dhwani
