Shadow Boards are visual methods of storing tools or materials and are always placed where the work is being done. Each shadow board consists of outlines or “shadows” in the shape of individual items to make it obvious where each should be put away. The shadow board accomplishes two essential goals of the visual workplace at once – it provides guidance for where to store things while at the same time making it obvious when a tool or item is missing. https://goleansixsigma.com/shadow-board/ Kanban is a Japanese term that translates to “card” or “board” and indicates some form of signal within a process. Kanbans are part of Just In Time (JIT) processing where either a physical or electronic device indicates that it’s time to order inventory, process a unit or move to the next step in a process. https://goleansixsigma.com/kanban/
