Rudi is today alone in his warehouse and he has to do the job Manfred, the Parts Picker, normally performs. Norbert, our mechanic, is showing up at the parts counter and asking for the parts to fix the brakes and replace the side-mirror of a customer. Rudi identifies the exact place where the items are stored, and hands them over to Norbert. He ships them to the Service Order. Then the next mechanic arrives asking with similar requests. Inventory needs to be updated with this activity, and the Inventory Manager needs to ensure that new parts are ordered if the minimum threshold is met, through the best possible vendor.
