A Red Tag is a labeling tool used in the Sort phase of a 5S as employees try to determine what’s necessary in a given workspace. They then place questionable items into a holding area and attach a red tag or label to each item. The information on a Red Tag can vary, but the goal is to determine if anyone thinks the item is necessary and, if so, in what quantity. Items are “red tagged” for a limited period of time and then given away, sold or recycled resulting in a less cluttered and more organized work area.
