That's probably a silly question, but I don't feel bad reminding anyone of the answer!
Last month, I took a little bit of a different angle to this question and asked, "What's the cost of listening (or not listening) to customers?" In that post, I mentioned that if we don't understand who our customers are, what jobs they are trying to do/achieve, and how well that's going, then we reap none of the benefits of having raving fans - probably because we won't have (m)any. So does it pay to listen? That's what execs want to know!
