Lean Tools for process improvement


Spaghetti Diagram

also known as Layout Diagram, Spaghetti Chart, or Standard Work Chart

Why use a Layout Diagram?

  • To draw simple Floor Plans
  • As a Spaghetti Map to visually illustrate how a process flows through a work space
  • As a Standardized Work Chart showing easy-to-understand visual work instructions

Sample Spaghetti Diagram Example

Why use a Spaghetti Diagram template?

Why not just draw by hand?

For the same reasons that you use any software

Familiar surroundings

Familiar Microsoft Excel

Use everything you know about familiar Word and Excel

  1. Save time — and money

    Not having to 'start over' for every little change

  2. Legible — so people can read it

    Maybe your hand drawings are okay, but how about your teammates?

  3. Accurate — so you can trust it

    Maybe your dimensions are precise, but how about your teammates?

  4. Training — and online help

    To remind people how to do this (infrequent) process improvement activity

  5. Standardized — consistent, teachable, repeatable

    So that everyone does it the same way

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.

How to use your

Layout Diagram template

Choose which template to use

The Layout Diagram is available in two ways:

  1. As a stand-alone template (LayoutDiagram.xlsx)
  2. As the 'Layout' sheet within your Standard Work template (StdWork.xlsx)

The stand-alone template is not available as a trial,
so trial users will use the 'Layout' sheet in the StdWork template.

Find and open your template

Excel Ribbon bar > Systems2win menu

Find and open your
Spaghetti Map template (LayoutDiagram.xlsx)
or Standard Work template (StdWork.xlsx)

in the same way that you find and open
your other 150+ Systems2win templates.

If you don't yet own a license,
you can download your free trial now.

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

Systems2win menu > 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 bar > Systems2win tab > Open a Blank Sheet

This blank sheet is where you will do your real work

(not on the Sample sheet)

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.

If English is not your preferred language

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

Now your team is ready to start using your

Spaghetti Diagram template

Process Observation template

Observe the process

Using one of your templates for process observation

Draw your 'As Is' process

Excel training:

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.

Get consensus that everyone agrees

messy boys

Who needs standard work?

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

Systems2win menu > Copy Sheet

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

Spaghetti Chart with Standard Work

Spaghetti Chart in Standard Work

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 floorplan 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.

See the Standard Work training and videos to learn more.
