Yes, I’ve seen some advocate the 6S and I’m always safety focused and that was how my last location was able to justify some changes that coincidentally improved the process but we never used 6S.
It’s almost the same with those who insist that there are now 8 wastes including “not using talent”. I guess “TIM WOOD” isn’t good enough a…[Read more]

Another bad test example?
Your total bad looks fine assuming the Z scores are correct.
I don’t understand your last paragraph. You have more defective on the lower side than on the upper side so you’d expect to have more than the normal distribution of 31.7% defective since you produce a higher defect rate on the lower side. Draw…[Read more]

@mike-carnell LOL about reading on the 3S….how about those doing “5S” without understanding how the process is supposed to work before doing a 5S event?

Discussion ensues better if you post the question and state the reasoning for the answer and then you can get neat feedback.

One can be utilized but not productive. I’d be open to learning/hearing why this has merit.
It’s sort of like a production line being “up/running” but only running at 10% of capacity–it’s utilized but not productive.
You will need to invest the time/money if truly want to understand your gage’s variation relative to the process and specification range.
However, you can get away with just doing 2 independent measurements by each of your 3 operators if you do the 10 parts–it’s a long discussion why this CAN be done in cases for expensive and time consuming…[Read more]
Non normality (bi-modal) is rarely caused by the gage but go ahead and perform a gage R&R. You realize the graphs shown don’t discuss process capability. You may be chasing your tail about a problem that doesn’t exist depending on if the specs are real and where they are.
I’d encourage you to use your process map to get other X’s and gather…[Read more]

You’ve just described a gage R&R. go for it and see what the folks are suggesting–the gage is not precise.
Chris Seider replied to the topic Measurement Systems – Difference Between Cg and P/T Ratio in the forum General 1 month ago
if you look at the formulas as you’ve written…..their relationship as you’ve indicated is inversed and a simple factor difference. However, Cg isn’t as commonly used and the 0.2 is a choice in some circles.
The P/T ratio is simpler because you know the ratio of the gage to the tolerance and ideal is 0.1 or less.

If you have lots of weeks of data for every year….consider a dot plot (or box plot) and you could do an ongoing run chart on the same display for a feedback loop.
