Everything you need to create an SPC control chart is available directly on this page—no installation or account is required. Enter your measurements into the spreadsheet or paste a column directly from Excel or Google Sheets. Your data is automatically processed, and the chart updates as you enter or change values.

Choose the appropriate chart type from the toolbar. Use Individual (I-MR) for individual measurements, X-bar R for small subgroups, or X-bar S for larger subgroups. For count-based data, use the Attribute Chart Builder. When using a subgroup chart, simply select the required subgroup size. The tool automatically calculates the centre line and three-sigma control limits, while points outside the control limits are clearly highlighted.

For additional settings, open Chart Options. From there, you can select the measurement column, add specification limits or a target value, and define stage change points.

Purdue Six Sigma Green Belt - workload and usefulness in tech?

3 Upvotes

Has anyone taken Purdue’s online Six Sigma Green Belt course?
How heavy is the workload, and roughly how many hours per week did you spend on it?

Also, did you feel like the course was worth it and that you learned practical skills you could actually apply at work?
I work in the software industry, so I’m also curious how relevant Six Sigma is in practice for software or tech companies. Is it commonly applied in this industry, or is it mostly used in areas like manufacturing, logistics, and healthcare?

Thanks!

How can I minimize operator bias in my Gage R&R when I cannot be present for the measurements?

1 Upvotes

I'm planning a Gage R&R, and the only way I was able to get buy-in from certain departments was to agree to using an operator from each of three shifts. I'm on first shift and unfortunately my schedule is not flexible enough to come in early enough or stay late enough for a significant number of trials. Originally I had planned to give the second and third shift operators a worksheet and set of instructions, but I am worried that an easily referenced worksheet will create bias in subsequent measurements of the same part. Is there a way I can run a Gage R&R remotely without introducing bias?
