Stephen Lahanas: In many ways, Enterprise Architecture (EA) is as misunderstood as Semantics. Although EA has been practiced across a much wider community of IT professionals for a longer period of time, it still suffers from an identity crisis. Is EA the mandatory precursor for model driven development, or is it part of a bigger picture and if so, what is that picture? It is my contention that the reason Enterprise Architecture is still misunderstood in many quarters and often unsuccessful in practice is precisely because it does exist within the context of a larger picture. All too often, that larger picture is simply ignored leaving those executing EA projects somewhat perplexed as to find meaningful ways to make their efforts relevant to the organization sponsoring their efforts.
