Spaghetti diagram

Concept

A drawing of the actual paths that people, parts or vehicles take on a floor plan. Tangled lines show unnecessary walking and transport, a form of waste.

Descrição

A spaghetti diagram is a line drawn on a floor plan that follows the real route of a person, a part or a vehicle while work is done. When the routes of a whole shift or a whole order are drawn, the picture often looks like a bowl of spaghetti, which gives the tool its name.

The diagram makes two kinds of waste visible: motion of people and transport of material. The team measures the distance, marks the crossings and long detours, and then moves workplaces, tools or storage closer to where they are used. A new drawing after the change shows the result in metres. The tool is simple and needs only a floor plan and a pen, and it is often a first step before a layout is changed or simulated.
