제목: Are Two Better than One? Individual Bias and Group Dynamics in the Newsvendor Decisions
초록: In a practice of a Sales and Operations Planning (S&OP), newsvendor decisions are often made by two parties in a firm, Sales Department and Operations Department. We examine newsvendor decisions in a group setting in comparison to a setting where individuals make decisions. In the Individual Treatment, we ask subjects to make all of the decomposed order decisions – point forecasts, distribution forecasts, and service level decisions. In the Group Treatment, there are two players framed as a demand forecaster who is in charge of making point forecasts and distribution forecasts, and an operations manager who makes service level decisions. We find no benefit of separating the newsvendor tasks into two players; individual bias in demand forecasts and alignment in the order decisions are not improved, and bias in service level decision and order quantity even worsen in the Group Treatment. We further examine how individual bias and group dynamics change with different group structures. Depending on the group structure, individual biases in component decisions can become more severe and alignment in the order decision can be worse. This emphasizes an importance of integrating a S & OP process as one body process as dividing the task between two players brings no benefit.
