gt replied to the topic Destructive testing in minitab in the forum General 20 years, 8 months ago
Not really, i want to know what to do in minitab with the parameters previously said
burn test
1 operator
minitab version 13.2
I’m aware of all the assumptions and so forth but with the parameters that i have, it looks like minitab doesn’t support this!
error message : you need more than one operator

if they follow the methodology and are able to demonstrate at least one tool per phase, we consider it (should) SS project.

to help you:

gt replied to the topic Gage RR on Weld Testing in the forum General 20 years, 9 months ago
the idea is to work with an assumption. As each part are destructed, we cannot conduct a second test. So when comes time to choose the parts, pick consecutive parts for one readings. i:e: 3 parts will represent the same part if you take 3 operators (that’s the assumption. we assume no change between these consecutives parts). Take 10 different (3…[Read more]

Welcome in the world of Six Sigma
You probably already have the easiest tool on earth to calculate process Sigma. Microsoft excel!!!
Also
1- z=((USL or LSL)-mean)/std deviation, the lowest will give you the process sigma
2- Another way, for the Dpmo long term to sigma short term conversion . Use this:
a=#defects

The lean brought us tools we can use in different phases of six sigma. i.e. poka yoke in the … phase, one piece flow in the …phase….These are tools we can use to reduce the leadtime and the defects in a process. Six sigma is a philosophy in wich we can use tools that will fit in the proper phase.

Yes, in minitab we should use the nested option. In minitab, we can only conduct a test with more than one operator. What if (as we are a small business and there is only one operator conducting the tests)there is only one operator?
