Very interesting Harvard Business Review IdeaCast (podcast) late last year called "Thinking Inside the Box". Is an interview with Kevin Coyne, coauthor of the Harvard Business Review article "Breakthrough Thinking from Inside the Box.".
We spend a lot of time thinking about innovation, change, re-engineering. As Coyne points out sometimes change does not require revolution - just asking the right questions.
