The Scope of Enterprise Architecture

July 24, 2008

I have struggled with the scope of enterprise architecture since the beginning.  EA is expected to align IT efforts with business strategy so that IT delivers things that add value.  In trying to do that better, I have spent a great deal of time defining IT Portfolios and a management structure around them.  I did this in order to define ownership, functionality, and a strategy for all the “stuff” we have, and so far it has been successful in giving myself and others a better handle on what we have and where we are going.

Does that mean that IT Portfolio Management is Enterprise Architecture?  They are certainly related.

Enterprise Architect’s focus on different aspects of IT; things such as System Reporting, Configuration Management, or IT Governance.  But the thread that runs through all of these is to understand where the environment is now so that we can decide and align where we should be going.

What isn’t the scope of enterprise architecture?

    To simplify EA, it is all about the structuring the current state (information, infrastructure, finance, organization, business & application) and creating a road map to reach the IT vision.

    Few key deliverables of EA are:

    IT Portfolio management
    Road maps
    Technology Road map
    Process road map
    Application road map
    People road map
    Standards & Policies (to ensure the direction is aligned and moving towards the strategy)
    Scenario Planning (to meet the explore the optimal ways to reach the strategy)
    Cost optimization plan
    Various vendor management model
    Various operating model (like ASP, SaaS, )

    Thank you,

    Thanks for your response Praba! I agree with your take on the deliverables of EA, but in a smaller organization I am also pulled into ‘operational’ concerns to ensure the successful delivery of strategy… things like IT Governance, Resource Planning, and Change Management.
