The assignment compares the distribution channels of Amazon and Walmart, two leading e-commerce companies. While Amazon is focusing on same-day delivery through a network of distribution centers, Walmart is expanding its e-commerce capabilities and leveraging its retail store presence for online order pick-up. The question is which approach will be most successful, with Amazon's goal being to deliver products the same day they are ordered, while Walmart aims to make products available for pick-up at the nearest store on the day of ordering.
