Host Diego Solorzano sits down with Arthur L Valdez, Jr., EVP Global Supply Chain and Customer Solutions at Starbucks. Together, they trace the evolution of global retail logistics, from Amazon’s groundbreaking fulfillment and sortation systems to Target’s transformative “stores as hubs” model. Arthur reveals lessons on balancing culture with technology, the rising role of AI, and how convenience is shaping customer expectations. He also shares leadership insights on tackling complex problems, mentoring diverse talent, and preparing supply chains for a future defined by speed, efficiency, and customer-centricity.

What you will learn:


Arthur L Valdez, Jr. is a veteran supply chain executive with over three decades of experience transforming global retail operations. As a former Vice President of Worldwide Operations at Amazon (1999-2015) and subsequent leadership roles at Target and Starbucks, he has pioneered innovative fulfillment strategies, including Amazon's international logistics expansion and Target's stores-as-hubs model. His expertise spans from scaling early-stage e-commerce operations to revolutionizing traditional retail distribution networks. 

Key Highlights:


Arthur reveals that sortation capabilities were the critical foundation that enabled Amazon's massive growth from processing individual orders to millions of daily shipments. By mastering the art of sorting products by size, location, and order composition, Amazon could dramatically cut throughput time while maintaining the accuracy of orders. This focus on sortation efficiency led directly to their current robotic fulfillment solutions, as human-only operations couldn't scale to handle millions of units per hour. The investment in advanced sortation technology helped Amazon evolve from 4-day processing times in 1999 to 30-minute deliveries today. 


Target's breakthrough stores-as-hubs model capitalizes on having 85% of the US population within 5 miles of a store to enable same-day delivery. This local fulfillment approach allows Target to split multi-item orders across nearby stores when needed, since the short delivery distances keep costs low. The model requires balancing predictive inventory placement with flexible logistics to ensure stores maintain the right stock levels. Success depends on investing in local sortation centers and delivery networks to make this distributed fulfillment approach work efficiently. 


Arthur highlights the fundamental difference between Amazon's "technology beats culture" philosophy and Target's "culture beats technology" mindset. This distinction has shaped how each company approaches innovation and customer experience, with Amazon heavily investing in automation while Target emphasizes human connection. However, the rise of AI and growing consumer demand for convenience is forcing traditionally culture-focused retailers to increase their technology investments. Companies that don't embrace both technological efficiency and cultural strengths risk falling behind as customer expectations for speed and service continue to rise. 


At Starbucks, Arthur tackled the challenge of long wait times caused by competing service priorities between in-store, drive-through, and digital customers. The solution involved creating algorithms to properly sequence and prioritize orders across channels while maintaining service promises. This required connecting point-of-sale systems with supply chain tools to ensure proper inventory levels matched service capabilities. The experience shows how applying technology to seemingly simple operational challenges can significantly improve customer satisfaction.
