2. As a result of the physical inventory counts, 143 parts (9.4%) were found to have differences between the physical inventory counts and the parts inventory levels recorded in the Faster System. There were 70 part numbers where the system count was over the physical counts and 73 parts where the system count was under the physical counts. The over results indicate that parts are missing from the inventory because they may have been issued as part of a work order but not reduced from system records, or they were removed from the warehouse unauthorized.
