Simply telling a business audience all the wonderful things that EA will do for you is not enough. Light bulbs go on only when you have a chance to show them what it means to them. So, don’t try to “sell” an audience on the academic virtues of EA. Show them. Use relationships among component parts and expose mappings that they always thought existed, but never quite had a chance to see before.
I was recently asked to reflect on the strengths of some of the EA practitioners I have worked with over the years. They have been an inspiring group who collectively and individually were drawn to EA because they aspired to make a difference in their companies. Fulfilling that aspiration isn’t always an easy path.
