Everyone has to go out and buy groceries, right? 

Well, it turns out that  at one time that would have been a correct statement; however, these  days things have changed and now customers have many choices on how they can get the groceries that they need.  This change has hit grocery store product managers very hard. All of a  sudden they find themselves having to change their product development  definition, overhaul their operations, and having to invest in new  technologies and talent in order to find ways to keep their customers  from shopping at Amazon for their groceries. Oh, and they also have keep  food prices low because that is what their customers expect.
