SpaghettiDiagramme

A Spaghetti Diagram is a visual tool used in lean manufacturing and process improvement to track and analyze the physical movement of people, materials, or information within a workspace. It is essentially a map of an area with lines drawn on it to represent the path taken by a worker, a product, or a piece of data as it moves through a process. The name "spaghetti" comes from the appearance of these diagrams, which often resemble a tangled ball of spaghetti due to the complex and often inefficient routes taken.

The primary purpose of creating a spaghetti diagram is to identify waste, specifically the waste of motion and transportation. By observing the winding and often redundant paths on the diagram, inefficiencies become visually apparent. These inefficiencies can lead to wasted time, increased fatigue for workers, and longer lead times for products or services.

The process of creating a spaghetti diagram typically involves observing a specific operation or process for a set period, documenting every movement made, and then transferring these movements onto a scaled layout of the workspace. The lines can be color-coded to distinguish between different workers, materials, or types of movement. Once created, the diagram is analyzed to find opportunities for improvement. This might involve rearranging workstations, optimizing material flow, or redesigning the process to reduce unnecessary travel. It is a simple yet powerful technique for visualizing and eliminating waste in physical layouts.
