Spaghetti Diagrams Six Sigma: De-Cluttering Production Shop Floors
Video explains how spaghetti diagrams are ideal six sigma lean manufacturing tools that help you to de-clutter your production shop floor. The process involves mapping out your shop floor on a white board or on paper by clearly defining separate work cells and work stations.
The first step involves speaking with your production employees and making sure they understand that you are tracking and measuring how work flows from one cell to the next. In essence, you are analyzing the process of work and not the individuals themselves.
Second, once you've mapped out your shop floor, you need to use sequential numbers and lines that define the current flow of work from one cell to the next.
Third, go onto your shop floor and use a measuring wheel to define the length in feet from one cell to the next.
Fourth, track the time it takes to move parts from one cell to the next. Pay close attention to any obstructions such as pillars and beams. Do not trace lines on your whiteboard or paper through these obstructions. It's called a spaghetti diagram because the lines go around these obstructions and not through them.
Finally, be sure to track the times and keep a running list of these times from each step in the production process. At the end of the exercise you should have a summary of distance between steps and time between steps.
In manufacturing, there is a cycle time for the finished good and then there are separate times for each operation. Part of the overall cycle time for the finished good involves the transit times between production work cells and stations. This means that reducing the distance between adjacent cells will lower transit times, reduce cycle times and increase production throughput.

Excellent & nice video!!!
🎯 Key Takeaways for quick navigation: Spaghetti diagrams are part of business process mapping and are effective for decluttering shop floors in manufacturing. Each operation in manufacturing has a cycle time, and reducing cycle time can increase production throughput. Transit times between workstations affect the overall cycle time for finished products. Spaghetti diagrams help identify roadblocks and issues causing delays or downtime in manufacturing. The process involves mapping out the shop floor, defining each step, and using sequential numbers to designate the workflow. Drawing continuous lines on the diagram represents the flow of work through the shop floor. Measuring the distance between steps and recording any delays or obstructions helps analyze production efficiency. By rearranging the shop floor layout to reduce travel time, production throughput can be increased. Spaghetti diagrams aid in optimizing manufacturing processes by capturing downtime, delays, and travel distances. Made with HARPA AI
I have one question about transit time. Let me put up a situation. If we from process 2 to 3 it take 60 seconds to move 10 parts at a time. 1 ) Transit time = 60 sec or 2) Transit time = 60 sec / 10 parts = 6 sec/part Which option shout we used. Transit time each and every component moves or transit time / component??

I won't claim to know the answer, but I would count based on the process. For example, if a single process takes 60 seconds to move 10 parts at a time, then I would put it down as such. However, if a single process takes 6 seconds to move 1 part at a time, then I would record it as 6 sec/part. Does that make sense?
Can the flow of information (over radio/in person) be included in a spaghetti diagram along with the physical movement of people/parts?

I think if the flow of information is separate from the physical movement and can be measured in time, then yes. But if it occurs in parallel to the physical movement, then there wouldn't be a reason to include it... Just my opinion, as I don't know if that's the right answer :)

A spaghetti diagram is just a tool, which you can use as you see fit. If the flow of information is taking up measurable time then it could be useful to display on the diagram, as it could increase process and/or total lead time.
So obvious.
