The Montgomery example appears to be from one of his books published in 1996. He uses the I/MR chart with transformed data to create a control chart of MTBF which is obviously going to not be a normal distribution. Since that time, Minitab has brought out the G and T charts for time between rare events. Po…[Read more]
Haven’t seen a lot of that in the industry. Some folks talk about it but I have not seen anyone actually execute it. On the other hand, I have seen GBs have a requirement for re-certification by having to do another project. Since MBBs and BBs are usually full time, their skills usually don’t deteriorate. There is opportunity for constant eva…[Read more]
I’m sorry that your training example didn’t work out the way you had planned!
Your example reminded me of a lean factory tour video I saw on Youtube recently by Paul Akers, the founder and president of FastCap, based in Ferndale, WA.
Hope the tour gives you some food for thought for your organization.
Minitab 18 has the same functionally as 19 for both regression and ANOVA — the output may look a little different, but all of the content should be there.
To Robert’s point, just make sure you always put categorical predictors in the correct window — if they are text values, Minitab will let you select them as categorical predictors without…[Read more]
@rbutler, Minitab doesn’t explicitly explain the process or refer to “dummy variables” in the output, but it shows the coefficients for k-1 levels for each categorical predictor (the first level of course is the reference, included in the regression constant). It also displays a separate regression equation for each combination of categorical…[Read more]
@rbutler is correct, but a lot of modern statistical analysis software will do all of that for you. I am currently using Minitab 19, and its dialog box for regression includes inputs for both continuous and categorical variables. For the categorical variables Minitab does just what Robert described, but it’s all in the background. You can also use…[Read more]
@sebvlarsen What do YOU think you should do? Why or why not? Be more specific about what problem you’re having and you’re more likely to get a response. People want to see that you’re putting in a good-faith effort to figure out the solution on your own.
@Sebvlarsen Did you search our site before asking your question? We’ve got a bunch of content on Gage R&R/MSA in our Tools & Templates section: https://www.isixsigma.com/tools-templates/measurement-systems-analysis-msa-gage-rr/

OEE is a great tool but not easy to “measure” if loss capturing isn’t credible.
I’ve helped many clients improve 10% output on poorly performing lines by finding either 1) easy to tackle significant loss buckets or 2) just providing instant feedback (even if just hourly) of how production is occurring so management and supervision has a chance to…[Read more]

Consider what you mean by target of 100%.
Your control chart would be great if no losses were assumed and the theoretical output was included–not planned output.
Planned shutdown times should ONLY include times where no one was employed to run the line. Routine maintenance and operator maintenance are still losses.
All calendar time should be included except for unscheduled run time for lack of orders or normal unscheduled time that isn’t manned.
Your scenario would have 24 hours in the…[Read more]

do you have a problem statement and a metric chart(s) that the project champion agrees are measures of success?

@kam221 Did you try searching our site for ideas? A quick search reveals a lot of results for “turnaround time” and “TAT”.

@datasciencedweeb If you are using a software package check it to see if you can list 100% as a boundary.
Have you been to any tournament lately for kids? :) All clear up here for this bud in Dallas but let’s hope recovery goes well for those souls impacted. I shop SOMETIMES at the Home Depot that got destroyed at Forest Ave in Dallas. That store manager that got everyone out and closed the store deserves a med…[Read more]
