  14. 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

  15. “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.”
