When a business personn asks me for a new feature I spend a couple hours discussing their requirements and customer needs. I make sure to ask the right questions and draw out corner cases they haven't thought of. The business person has a bit of training to put forwar their requirements correctly A doctor might spend 5 minutes listening to your symptoms, you have no training on how to recall them correctly or bring up the right ones. Another 5 minutes might be spent discussing treatment. And you life might depend on this
