> primarily on the basis of their domain knowledge This is a _HUGE_ loss to a company when a company loses someone with domain knowledge. Putting people into the "Are they good at skill X? Where X is the specific thing their title says they do." box and then hiring and firing based solely upon X is foolish to the extreme. If someone is mediocre at X but understands the business domain that they are working in they are worth the same as someone who is highly talented at X but doesn't know the domain. And while people can "learn the domain" most people don't actually want to. They'll learn it until they have passing knowledge but won't actually ever take the time to really understand it.
