  15. apple macintosh “Instead of arguing about new software ideas, we

    actually tried them out by writing quick prototypes, keeping the ideas that worked best and discarding the others. We always had something running that represented our best thinking at the time.” “The Macintosh Spirit” | http://www.folklore.org/StoryView.py?project=Macintosh&story=The_Macintosh_Spirit.txt
  16. “I think building this culture is the key to innovation.

    Creativity must flow from everywhere. Whether you are a summer intern or the CTO, any good idea must be able to seek an objective test, preferably a test that exposes the idea to real customers. Everyone must be able to experiment, learn, and iterate.” amazon’s innovation culture http://glinden.blogspot.com/2006/04/early-amazon-shopping-cart.html
