The Water Spider picks up raw material from the warehouse (filling station) and delivers the raw material to the manufacturing workstations. The Water Spider then picks up the empty containers from each workstation and delivers them back the warehouse to be refilled. This is the Water Spider run or route. Each container is refilled with standard quantities. The standard quantities delivered must last just long enough for the Water Spider to arrive on the next run. The Water Spider run may take 20 minutes to complete. That means each workstation will have 20 minutes of raw material delivered. The implementation of a Water Spider keeps inventory to a minimum. The Water Spider absorbs nonvalue added activity allowing the workstations to focus on value added activity.
