"Amazon has introduced many incredibly advanced supply chain management practices that have led to its domination of online retail and e-commerce offerings. From my research and understanding, Amazon outsources its inventory management tasks while insourcing logistics. Third-party sellers account for more than half of Amazon's sales, and other products that are not ordered as frequently are not stored in Amazon warehouses. The company's same-day and now 2-hour shipping service is possible because Amazon cut out third-party carriers as much as possible. Amazon primarily relies on its own delivery vehicles for these same-day shipping options. Dividing warehouses by delivery options is an important point for me to note, as well. By having different warehouses for Prime, one-day delivery, and more, Amazon can streamline its operations and prevent delivery challenges that commonly cause delays for its competitors. I am excited to learn more about Amazon's unique efforts for meeting customer needs while continually changing the way we approach logistics."
