An interview with Dan Roam, author of The Back of the Napkin: Solving Problems and Selling Ideas with Pictures, which I need to remember to buy:
Today there are great drawing tools in a lot of software packages, and many business people, bless their hearts, are getting better at using them. The problem is the pictures look perfect when theyÄôre done. And by virtue of looking finished, they actually turn off peopleÄôs desire to constructively comment on them.
