Enterprise Architecture is one of those annoying concepts. It can generally be perceived as being either too complex ("You want to know everything to an excruciating level of detail!") or too simple ("It's a spreadsheet with a list of our apps on it - what's the big deal?")  The real truth about Enterprise Architecture is actually somewhere in the middle of that continuum.

The document "Getting a Return from EA Modelling - A White Paper: is an attempt at identifying how the four key segments of Enterprise Architecture can be usefully combined to create some sort of workable solution that you can use to effectively manage and promote EA in your organisation. It does this through 'Comerford's 4 tier EA Model'

The model efficiently links Business Process Architecture to Data Architecture to Application Architecture to Technology Architecture by helping you understand that it is the business needs which drive the architecture through changes to business process. These then follow the model through to DA, AA and TA segments to ensure a holistic and enterprise-wide view of EA
