Often, very talented technical people find it extraordinarily difficult to take the viewpoint of customers, who are often ignorant about the technology and who may have strong and perhaps incorrect prejudices about it. The technical people may believe, deep down, that they know better what customers "should" need. Customers, of course, have a different perspective. They want products that will solve customer problems and provide other customer benefits, and will do so without undue risk or cost. Not infrequently, customers view advanced technology itself as a risk.
