In 2012 several retailers, including Amazon and Walmart, experimented with same-day delivery. Home delivery of pizzas had been a very successful model in the United States and had been copied all over the world. In contrast, home delivery attempts by companies like Kozmo and Urbanfetch had failed and both companies went bankrupt. The goal of this case is to build a framework that helps students identify the factors that influence the success or failure of home delivery models.
