I think that's two different, but related problems. "what should we build?" is a different problem from "what do you think we should be building?" - the first is a customer discovery problem (what do our customers think they need?), the second is a communication problem (what does our manager want us to build?). The related bit is that humans are bad at communicating and we need to spend a lot of effort deciphering ambiguous human waffle into precise program code.
