Techopedia explains Spaghetti Diagram
One of the major benefits of a spaghetti diagram is that viewers can see how items move, physically or conceptually, within the system. They can observe these complex relationships to try to make them more efficient or to cut down on waste. For example, someone creating a spaghetti diagram might draw rectangles and circles that represent actual workstations in a manufacturing process. The presenter draws a line wherever a product or material moves between different workstations. In many cases, changing the process can make these workflows simpler and boost productivity.
