We had a recent 5S project in our shipping warehouse where our forklifts would pick orders. The visual system that was in place on our inventory racks were basically non-existent. We were having a large turnover in staff and anytime we had a new forklift driver, it would take them months to grasp what aisles and racks to go to and pick the correct parts on the orders. Only the drivers that worked at the company for a long period of time would know where to go, however, this was causing quality issues because of the wrong items being pulled. The warehouse lacked visual signs and proper grouping of parts on racks. We ended up grouping like/similar parts together on the racks with large visual signs that we made using a label printer. It was a large project but the quality issues have improved greatly in our shipping department.
