If you are interested in Innovation and how companies can be classified in terms of their innovation management approach, then this article from Gary Hamel is definitely worth reading.
My favorite quote is:
Fourth are the cyborgs, companies like Google, Amazon, and Apple that have been purpose-built to achieve super-human feats of innovation. You won’t find much industrial age DNA in these organizations. These companies have been built around principles like freedom, meritocracy, transparency, and experimentation. They are so endlessly inventive and strategically flexible they seem to have come from another solar system–one where accountants are treated as servants rather than gods.
