In this report from the field, computerized auditory feedback was used to inform order selectors and order selector auditors in a distribution center to add an electronic article surveillance (EAS) adhesive tag. This was done by programming handheld computers to emit a loud beep for high-priced items upon scanning the item's bar-coded Universal Product Code (UPC). Adding the auditory component to the visual component of the handheld computer significantly decreased the number of untagged EAS items leaving the facility. The role of the organizational behavior management practitioner in applied settings in designing interventions--some of which can be quite simple and inexpensive, yet add tremendous value--was examined.
