ISO Plot Training arms Green Belts with a simple but effective Measurement System Analysis technique. Oklahoma is tied for #2 with Arkansas and Louisiana as a state recommended for ISO Plot Training because it's close to HQ, inexpensive, has cool alabaster caverns and hundreds of lakes!
ISO Plot is borrowed from the Shainin RedX tool kit. It has many similarities to Gage R&R in that multiple operators are measuring the same parts. However, in this case only 2 operators measuring at least 12 parts once each. Then, simply:
|Hand-draw a scatter plot of the points|
|Make observations about the pattern|
|Do some simple algebra|
|Decide whether the measurement system can be used|
