A reverse innovation is any innovation that is adopted first in the developing world. - Vijay Govindarajan

Inside a big experiment, there are little experiments.

Innovation plans, by contrast, are loaded with assumptions. Sure, some hard facts are available, but more is unknown than known. The past is no longer precedent. Thus, the innovator's job cannot be to deliver a proven result; it must be to discover what is possible, that is, to learn, by converting assumptions into knowledge as quickly and inexpensively as possible.

Of all possible resources that a firm might possess, its knowledge base has perhaps the greatest ability to serve as a source of sustainable differentiation and hence competitive advantage.
