Core idea
A spaghetti diagram traces actual movement to expose transport, walking, reaching, crossing, and layout complexity.
Method
Define subject/time, observe representative cycles, draw path, measure distance/frequency, redesign point-of-use layout, retest safety and ergonomics. Do not infer movement from floor plans.
