What do you think of Uber's market experimentations, as well as its novel but unsuccessful efforts like its troubled leasing program? Is this "spaghetti management" (meaning throw it at the wall and see what sticks) or a systematic exploration of growth opportunities in an attempt to gain a competitive advantage before others arrive? Would the company have been smarter to focus on the profitability of its core business first, or is it smarter to stretch its reach into potentially lucrative new areas?
