Is a common phrase used when asked in what domain does you approach work? Of course without a test of that idea outside the domain in which the anecdotal example is used, it's going to be hard to know if that idea is actually credible beyond those examples.
So if we hear we've been successful in our domain doing something or better yet NOT doing something, like say NOT estimating, ask in what domain have you been successful?
