Much of what I see in large diversified corporate institutions is the application of EA principles and frameworks, without an underlying mechanism to measure or substantiate through research that EA techniques provide value. The value, could be the result of a hidden value chain (systems thinking), or discrete units of measure (defect reduction or financial indicators such as cost avoided), or perhaps social-cultural through the alignment of individual objectives with that of the enterprise. On the whole, a general lack of research basis seems to exist in the EA value measurement facet, but admittedly my own biases cloud my field of view - which is best remedied by the input of others who see EA differently and perhaps suggest research areas that could support or dismiss EA's core value propositions.
