Introduction

    Would you build a house without a blue print? I didn’t think so. But many companies

    build enterprise applications without an Enterprise Architecture. Even if your company

    chooses not to fund an EA initiative, you can still follow an EA framework’s thought

    process the next time you take on a major enterprise initiative. If you are working for a

    startup and building you products and services from scratch, you would be wise to

    leverage some of the best practices of an up to date light weight framework like the

    Extended Enterprise Architecture Framework (E2AF). I created this document as a

    cheat sheet based on the 6x4 E2AF matrix that guides architects through a robust process

    from planning, analysis, requirements, and design. You owe it to your company to at

    least consider the following questions from both the business and technology view points.

    Feel free to download and distribute this document. It is my contribution back to both the

    EA community and to my fellow IT colleagues. I am tired of hearing about the horror

    stories of IT failures and hope that this document can be of use to my talented colleagues

    around the world, as we attempt to create business value by leveraging the skills and

    knowledge of our profession. Enjoy!

    like to give me feedback.

Scope

    This scope of this document is to answer the six basic questions (Why, With Who, What,

    How, with What, and When) from the Extended Enterprise Architecture Framework

    (E2AF) from four perspectives: Business, Information, Information Systems, and

    Technology Infrastructure.

    A great summary of E2AF can be found by clicking on this link located on the website

    for the Institute for Enterprise Architecture Developments.
