Well, they'll work for what you have now. They won't work for what will make your company viable in the future. With all the Steve Jobs quotes and memories being shared I read one that struck me. It was about why he doesn't use focus groups, and rather than explain it himself he quoted Henry Ford: “If I had asked my customers what they wanted, they would have said a faster horse.” Most people don't see the future, it takes someone with a forward view to change the world. Stop doing focus groups and start changing your mindset.
