While using this option in Minitab 15, the 4 columns : StdOrder, RunOrder, Parts & Operators actually do not give the measured values. i.e the actual measurements. Then how is this option helpful in day to day life of a SixSigma Professional....guidance appreciated....

Gud times...

The Parts column is for the serial number of the parts that are to be measured. the serial number is arbitrarily chosen. You can select a bunch of parts and give them their serial numbers in any order (say time of production, increasing size, decreasing size or just random)

The Operators column gives the serial number (or names) of the operators who carried out the measurements.

Standard Order is the systematic order which we get while listing down all the combinations of Operators and parts along with the number of trials to be done.

The Run Order is a randomized order in which the measurements have to be carried out in order to eliminate any systematic error from affecting the measurements.

the result of the measurements have to be collected and entered into minitab in the Measurement column. (Arranging the table according to run order and collecting the data according to run order will help ensure the correct entry)

Now please repeat your question again after taking into account the above explanations of the different data required for the analysis of the Gage R&R study.

Note:

1. the create Gage R&R study worksheet option is not meant for creating a "sample" data for doing a Gage R&R study, but to help one to list out all the required combinations of the parts and operators and trials and for suggesting a randomized run order

2. the run order can be different each time you try - because it is randomized unless you use the same random seed

3. however the standard order and the corresponding part and operator numbers would remain the same for the given number of parts and operators and trials.

 

Hi Mr Bala,

Your explanation clarifies my doubt. So, it acts as a guideline for deciding the sequence of runs used "to eliminate any systematic error from affecting the measurements".....

As stated in Help example in Minitab, the Operator 1(3 operators) tests the Part 3(then part 14)(15 parts) as 1st Run(system generated order).

I have the Agent, the Part mentioned(to be measured) & Run Oder(the sequence...flow). How will Std Order help. Would appreciate if can be explained.

Once again, thank you for the assistance....
