The focus of this study was to compile and interpret drop heights and drop frequencies data for small parcel packages moving through the Eastman Kodak Company global distribution network. The need for this study arose from the inclusion of drop height probability curves into Kodak's shipping tests for packaged product weighing less than 100 lb. Kodak packaging engineers suspected the drop heights included in the probability curves were too high in drop height and too many in frequency when compared to the actual distribution environment. The data for this study resulted from dozens of test shipments using dummy-load packages throughout the Kodak global distribution network. The test shipments were conducted in the United States, Europe, and Australia. The test packages were equipped with a drop-height recording device called a SAVER to record when a drop occurred and from what height the package was dropped. Data from the recorder was downloaded, "real" events were sorted out from events that were not true drops. Once sorting was completed, the "real" data was analyzed utilizing various statistical techniques. The results of the analysis led to the development of data-derived statistical test plans based on the actual field-measured data. The results of this experiment, when compared to the probability curve currently in use, show that the drop heights outlined in the probability curve are too high and too many are called for. This experiment will serve as the basis for new shipping tests based on actual field measurements. The field data indicates that the current test may have led to overtesting and overpackaging of our products. These findings identify an opportunity for waste reduction as well as an overall reduction in expenditure for packaging.
