Most forecasting goals focus solely on accuracy, but Harrison Katz reveals why understanding the true purpose of forecasts can transform how organizations make decisions. From leading Airbnb’s demand predictions to academic research, he uncovers the nuanced role forecasts play beyond numbers—and why misaligned goals and governance can distort the entire process. In this episode, Harrison shares his nonlinear journey from dropping out of high school at 15 to leading Airbnb’s forecasting strategies across hundreds of global markets. He discusses how COVID-19 exposed the limitations of traditional models and taught invaluable lessons about system agility, regime shifts, and the importance of separating models for flow versus lead times, and not for supply versus demand. Harrison breaks down the often-overlooked concept of forecast governance, emphasizing that forecasts are not just numbers—they are political, strategic, and even behavioral tools that influence outcomes.

This episode of Forecasting Impact features Professor Lauren B. Davis discussing her research on applying stochastic modeling and forecasting to food bank operations. Lauren shares how she began forecasting with a local food bank, which led her to focus on forecasting the highly uncertain supply of food donations. She details the food banks' donation sourcing process, the management of their supply chains, and the application of models like exponential smoothing, support vector regression, and ensemble methods to predict donation volumes. Professor Davis addresses challenges in forecasting at various aggregation levels (network vs. location-specific), using optimization models for equitable allocation of limited supply, and the significance of storage and agency capacity limits. She emphasizes the importance of equity as an objective, the complexity of modeling true demand, and the crucial role of visual analytics and co-design with food bank partners. The episode underscores the practical impact of forecasting in humanitarian supply chains and the necessity of linking models with operational decisions.
