But is this really the point of the article? The article argues that it is difficult to identify expertise. However, the situation you describe is one where (if I read you correctly) not your expertise was questioned but your recommendation. If there wasn’t any tangible difference between the CTO’s and your suggested course of action on a metric that he as a customer cared about, then maybe his proposal was indeed the better one? And yes, probably he didn’t care about the exact latencies in the system, but he would probably care about customer retention, system availability, etc.?
