"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.
