" Above all, we know that an entrepreneurial strategy has more chance of success the more it starts out with the users – their utilities, their values, their realities. An innovation is a change in market or society. It produces a greater yield for the user, greater wealth-producing capacity for society, higher value or greater satisfaction. The test of an innovation is always what it does for the user. Hence, entrepreneurship always needs to be market-focused, indeed, market-driven. "
