also known as Layout Diagram, Spaghetti Chart, or Standard Work Chart
Sample Spaghetti Diagram Example
Why not just draw by hand?
For the same reasons that you use any software
Not having to 'start over' for every little change
Maybe your hand drawings are okay, but how about your teammates?
Maybe your dimensions are precise, but how about your teammates?
To remind people how to do this (infrequent) process improvement activity
So that everyone does it the same way
Familiar Microsoft Excel
Use everything you know about familiar Word and Excel
Since your people already own and know how to use Microsoft Excel,
your people have a much higher probability of actually using this powerful standardized work chart.

You will find the Layout sheet as a tab within your StdWork trial template.
Save your working document
following the usual document storage and naming conventions established by your leaders
Open a Blank Sheet
When you're ready to start doing your own real work...
click the button to 'Open a Blank Sheet'
Excel Ribbon > Systems2win tab > Open a Blank Sheet
This blank sheet is where you will do your real work

Rename your new sheet.
Or... Insert Sheet
As an alternative to opening a stand-alone document (as instructed above),
you also have the option to Insert Sheet into any other Excel workbook.

Switch to your language, just like every Systems2win Excel template.

Draw your 'As Is' process
On the 'Help' sheet of every Systems2win template, there is a section for 'Excel Tips most valuable for THIS template'
Go to that section of your 'Help' sheet now, and follow the links to learn how to use Excel as a drawing tool.
Draw boxes for work areas and material supplies
These should be roughly placed as they are on the physical floor.
If exact measurements are important, you can use the grid, and/or shapes to indicate measurements.
Add a brief name or label to identify each work center box.
In this spaghetti Diagram illustration, the blue rectangles with a green arrow are gravity-fed inventory racks.
Feel free to invent your own shapes for material handling equipment unique to your process.
Next, add operation numbers in circles.
If you this process also has a standard work combination sheet, then the operation numbers on your spaghetti chart should usually correspond to the Work Element numbers in the standard work chart.
Next, add Operators
One 'operator' symbol per operator, and then empty circles for each additional place where that operator stops to work.
Red lines with arrows indicate the walk path.
Use a dashed line to make it clearly visible if a worker has to backtrack.
Next, add Work In Process (WIP) inventory.
using green-striped WIP circle shapes, with a number indicating how many WIP items are usually found there.
Don't count the part that the operator is carrying or handling, but only parts that are left in a machine or work center after the operator moves on.
Next, focus on Safety
Identify any work areas that have safety concerns, using the shape of a red or green cross, (similar to the shape used for a first aid kit).
Next, focus on Quality
using the shape of a green outlined diamond wherever quality is checked,
and the shape of a red stop sign with a 'Q' in it wherever there might be a quality issue.
Next, focus on Flow
Show the direction of the flow of the thing being processed, using a green arrow, and following the instructions for how to make a bent arrow
(the link to those instructions are found in the Excel Tips section of the Help sheet in LayoutDiagram.xlsx)
Enter (optional) summary data
Perhaps Total Standard WIP, lead time, cycle time, staff level...
Finally, you can (optionally) add explanatory notes
using text boxes, arrows, and/or clouds and bursts.
Get consensus that everyone agrees
Get consensus that everyone agrees that your "As Is" process is an accurate representation for the way things really are now.
Analyze the 'As Is' process
Use your Takt Time Calculation template (Takt.xlsx)
What isn't ideal?
Are there loops?
How might time & distance be reduced?
Are all of the steps necessary?
Could some steps be combined?
Consider all aspects of the Toyota 4 Rules in Use
Perhaps use your Standard Work template to perform a thorough process analysis
Perhaps return (again and again) to the Hansei questions to stimulate Lean Thinking
Who needs standard work?
Improve the process
Copy your "As Is" sheet to serve as the starting point for your "To Be" sheet.
Use the special Systems2win utility: Systems2win menu > Copy Sheet
The greatest power of your spaghetti diagram is when you print it out and post it on the shop floor along with printed Standard Work Instructions.
Each circled Operation Number on the standard work chart usually corresponds with a Work Element on the Standard Work Sheet.
Your Standard Work Instructions (often with floor plan map) get printed and taped up right in front of each worker at their work station, to remind people of the right way to do each job, thereby eliminating costly quality mistakes.
