To all the test engineers out in test land. If your manager says that you an unlimited amount of time
and money to develop and tweak your test program and redo loadboards that have problems, then
read no further.
If however, you are interested in learning a 45 second process to KNOW that ANOVA GRR or
XBAR&R GRR will pass at 10% or 5%, please contact me. Skype: venanzio0812, email:

Learn how much the instrument specification alone affects GRR.
Learn how qualification samples location affects GRR.
Learn how to put infrastructure in place so that 45 seconds of time spent per test will allow you know
before the test program is written and before the loadboard is built to avoid lost time and lost money.
Select USL, LSL, condition, and # of instrument errors. The tool will advise which ranges will achieve
the desired GRR.
