In this podcast, they discuss the challenges and trade-offs of operations management. They use a case study of transporting 25,000 roses for a flower shop on Valentine's Day to highlight the importance of planning and flexibility. They also explore the concept of the 'news vendor model' and discuss the pros and cons of self-checkout machines in retail stores. The podcast offers insights into handling uncertainty and optimizing operations.
Operations management involves planning, embracing uncertainty, and managing variability to keep businesses running efficiently.
Optimization and efficiency in the global transportation chain can ensure timely delivery of products despite weather-related uncertainties.

The Importance of Operations Management
Operations management is crucial for businesses as it involves optimizing processes, managing the supply chain, and ensuring efficient operations. Operations managers are unsung heroes who ensure that businesses run smoothly and effectively. They use tools like planning, embracing uncertainty, and managing variability to keep operations running efficiently. For example, a well-run coffee store requires careful coordination of coffee bean delivery, machine specifications, milk, sugar, cups, and baristas, so that customers experience smooth service.
The Valentine's Day Rose Supply Chain
The story of a flower shop owner, Jan Oombs, reveals the challenges and complexities of the rose supply chain for Valentine's Day. Oombs ordered 25,000 roses from a farm in Ecuador and needed to ensure they arrived in New York City on time. The farm faced weather-related uncertainties, with roses needing the optimal amount of blooming by a specific deadline. Plant engineers like Hector had to use various techniques to speed up or slow down the roses' growth to meet the deadline. Despite the challenges, the roses arrived one day late but still in perfect condition, highlighting the optimization and efficiency of the global transportation chain.
The Rise of Self-Checkout Machines
Self-checkout machines have become increasingly prevalent in grocery stores, offering a faster alternative to traditional cashier lines. Howard Schneider, the inventor of self-checkout, faced initial resistance from stores but eventually found success with his machines. The machines initially faced technical difficulties and required assistance from employees, but over time, they have become better designed and more efficient. While customers may have mixed feelings about self-checkout, retailers benefit from the cost savings and increased convenience it provides.
Understanding Lines and Bottlenecks
Long lines in stores often result from a lack of capacity or variability in the process. Limited staff or inefficient operations can lead to bottlenecks and slow down the entire line. Different approaches, such as dedicated lines for each cashier, help reduce variability and create more consistent lines. The goal is to balance efficiency, capacity, and customer satisfaction in managing lines and operations.
"It's difficult to control everything," says our guest professor for this week, Santiago Gallino. "What is not difficult is to plan for everything." Today we venture into the sphere of business that masters the planning, and backup planning: operations management.
It's more than just predicting a bottleneck and imagining a solution, because there's always a bottleneck to clear. It's about modeling, and weighing the costs of messing up vs. missing out. For instance, take a newspaper vendor who has to decide how many newspapers to sell tomorrow morning. Do they buy fewer, knowing that they'll sell out–and then miss out on potential revenue from papers not sold? Or do they order more than they expect to sell, just in case–and eat the cost of a few unsold papers? This type of trade-off applies to all kinds of businesses, and Gallino talks us through how to choose.
The only certainty in this life is uncertainty. But we are certain you will come out of this episode feeling better prepared for your future business. And fortunately, there are no bottlenecks in podcasting.
