The book: The Art of Innovation: Success Through Innovation the IDEO Way
Author: Thomas Kelley (co-founder of Ideo)
Genre: Business/idea generation
A thought-provoking book about brainstorming and product development, Ideo-style. Worth reading both because of the practical tips on how to develop innovative products (and innovative cultures), and because of the portrayal of Ideo, a super interesting product development company. Lots of good case stories, as well.
