Measurement of ROI for EA?

ROI (return on investment) for EA(enterprise architecture) is too difficult to measure. We can probably measure nonfinancial or nontangible benefits like stakeholder satisfaction, but turning these to money is just nonsense. However, we can show the logic how EA contributes in company goals.

EA What is it?

Enterprise architecture is an integrated combination of Business Strategy + Business Architecture + Business Culture + Technology Architecture.
The “fundamental conflict among the so-called experts” is not about the contents of EA, if anything, it is about the relative significance and contribution of each aspect. Pro vs. Anti IT is about relative significance and contribution of IT (or business strategy, business architecture, etc.) at a particular point in time.

The ‘how to do it’ question is entirely different and is concerned with frameworks, methodologies, techniques, training, etc. There are “coherent, rational, theoretically and empirically sound EA methodologies”.
