How, according to the Christensen reading, did the "job" commuters hired a milkshake for differ from the job parents with children hired it for? If the milkshake was going to be improved, how would "improvement" differ from one segment to the other? (I.e. what would make it better for a commuter vs. what would make it better for a parent?)

How could this approach to segment apply to other products? What products can you think of that would be "improved" differently depending on the "job" the Clint is hiring the product for? Explain how your approach would differ?
