Abstract
There has been a growing body of research over the past several years exploring repetitive behaviors of cashiers in supermarket checkouts. These studies were designed to increase the knowledge about biomechanical and physiologic stressors on the cashier during their most repetitive tasks, scanning products, rather than understand the impact of these tasks on customer service. The research described in this paper summarizes results from over thirty recent studies to determine the corroboration of these findings with the biomechanical research. The results from these productivity analyses showed that when effects of staffing, mixes of transaction sizes and types of tendering are normalized, the Front Facing checkstand was the most productive during the most repetitive tasks, scanning and keying product information, and from the total transaction time. These findings are similar and support those previously reported in the biomechanical research on cashiers using scanners.
