"The water spider is a term that refers to a specific person whose main job is to make sure that materials are supplied to where they are needed. While this is mainly a material replenishment position, it offers a bit more flexibility, and some additional benefits if well-implemented. The rationale behind having such a person is to allow the rest of the personnel to devote their full attention to tasks that add value to the process. This also highlights how much transportation waste and inefficiency exists in the process by isolating it all into one or more positions."
