Customers frequently request features.  However, if your company is operating from a customer-centric point of view, you should take care in asking the customer why they want the feature they asked for and what business problem the feature addresses.  You may be surprised how much critical insight comes out of this discussion and very often the opportunity to be innovative is just around the corner as you may identify a better way to solve the customer's problem than the feature they asked for does

All too often I've heard sales people answer the question with a yes or no answer and consequently blow an opportunity to move one step closer in establishing a trusted advisor relationship with their customer.  By consultatively digging into the customer's problems, not only do you discover information that may be key to your company's success, but you also demonstrate to your customer that you care, and you're committed to building a relationship with them that is based on the value you deliver in solving their problems.

Features are definitely interesting, but benefits matter most.
