Spaghetti Diagram
Reference model
The spaghetti diagram shows the flow paths in a process, with lines representing movement.
About this model
A visual representation that maps the movement of materials or information in a process, highlighting inefficiencies and redundancies.
Originator not stated.
How to read it
- Look for long, tangled lines indicating excessive movement.
- Identify areas where paths cross frequently, suggesting inefficiencies.
What this does
Visualizes the flow of materials or information in a process to identify inefficiencies and areas for improvement.
When to use it
Use it when you need to analyze the movement of people, materials, or information to pinpoint waste and streamline processes.
Not when: Do not use it when the process is too complex to visualize clearly or when there are no significant movements to analyze.
What happens next
Consider a process mapping tool to further detail the identified inefficiencies.
