Home > Lean Terms & Definitions > Water Spider


An insect that whirls on the surface of the water very quickly is called a Water Spider. In the Lean factory, the term is used for people who service work locations with parts or materials. They replenish point of use supplies, such as drill bits, and enable the production worker to only add value. That is, “they keep the surgeon at the table.” Water spiders are assigned any number of value-added and non-value- added but necessary tasks to provide the required support.
