purpose-driven innovation

You have doubtless visited a hotel or restaurant or other service business where a small box invited you to offer suggestions on "how can we better serve you?" Very likely, you never bothered to make a suggestion because, like most people, you sincerely doubted anything would happen to your suggestion. Indeed, I often wondered if such boxes were ever emptied and suggestions read! In other words, you probably didn't make the effort to offer a suggestion because there seemed to be no purpose to doing so.
