A Chance To Share In Munich

Manage to earn a chance to share my knowledge in Six Sigma & Lean with my counter part in Munich.

This is the first Black Belt training ever I participate, involving Green Belt candidate from Malaysia, Germany & China, it is quite an exciting experience to work with a group of counter part from different country, where we are facing some language problem, yet we manage to over come it and work together to achieve our objective.

In prepare some practical game to make the training fun, fortunately it works well despite facing some time constraint, in general, I m happy with the outcome for this round.

Together with me, there are three trainer from Germany and one from Malaysia.

How Minitab draws the line and determines significant effects on the normal plot of the effects

In the last knowledge sharing session, I share about 2k factorial DOE with Minitab. Somebody ask how actually Minitab define the red line in the Pareto Chart of Effect, and what is Lenth's PSE


Answer given to the audiance during the knowledge session was : sorry, I don't know.
Anyway, I try to find out the asnwer yesterday and here the answer I get.

Reference document

I try to work out the number with the example I shared, fortunately, I manage to workout the answer manually.

Just follow the step below, I believe you guy can get the answer as well

Step 1 : Stat > DOE > Analyse Factorial Design
Check Storage & Effect as shown in the picture below


Copy the value of EFFE1 and paste it into Excel for manual calculation
Table as shown in the picture below. You should able to get Lenth's PSE of 11.4375

In Minitab, the Red Line of Pareto chart is named as Margin Error (ME).
ME = t x Lenth's PSE

Where t can be find from t distribution.
Cal > Probability Distribution > t
Refer to Ref Document above.



Finally, I got the answer.
