Behavioral and experimental research in operations management has become well accepted; using one of my recent research projects, I provide an introduction into the field, as well as an introduction into running behavioral experiments. Specifically, in three separate behavioral laboratory experiments, we compare newsvendor ordering decisions made directly to newsvendor, ordering decisions made in a decomposed way by soliciting point forecasts, uncertainty judgments, and service level decisions. We demonstrate that while this decomposition approach may sometimes lead to better decisions, it can also fail to improve decision performance, particularly if the underlying demand uncertainty is too high, or if the cost structure emphasizes underage costs. We further demonstrate that if accompanied by decision support in the form of suggested quantities, task decomposition becomes the better performing approach to decision making more generally. Decision support and task decomposition therefore appear as complementary methods to improve decision performance.
