That makes it the single largest contributor to the verification cost this series has been tracking, and the reason people who carry it stay hard to replace. This piece covers what an engineer who knows the business does differently with questions, exceptions, and requirement interpretation, what breaks when the words used in meetings and the names in the code diverge, a six-step procedure for learning a domain, and the honest limit that domain knowledge does not transfer. The final part, 10 of 10, of the What Stays Expensive series.
