Van Loon replied to the topic BB/MBB training/certification in the forum General 14 years, 6 months ago
I was hoping, not all training companys were like this.
What is the most serious company ?
If you know that training is all you get, and you must make the most of it yourself, you were not fooled or tricked.
Like in most other parts of daily work, the training is the easy part, applying it is the hard.

So, taking training and certification, is a joke no matter
what company offers it. Bummer.

Van Loon replied to the topic Cpk – Excel vs Minitab results in the forum General 14 years, 6 months ago
You have calculated Ppk, not Cpk, in Excel.
That coresponds fine with Minitab.
Maybe the big diff. in Cpk and Ppk you get is due to
your data not beeing all that normal. (AD p.value 0,04)

Van Loon replied to the topic Hypothesis test – advice please in the forum General 14 years, 6 months ago
Yes, if you only get 0,17 your power is reduced.
If you want a bigger power, you need more data. -
Van Loon replied to the topic Hypothesis test – advice please in the forum General 14 years, 6 months ago
I wold say 8 months, if you want a power of 0,8.
Power and Sample Size
2-Sample t Test
Testing mean 1 = mean 2 (versus >)
Calculating power for mean 1 = mean 2 + difference
Alpha = 0,05 Assumed standard deviation = 1,3
Sample Target
Difference Size Power Actual Power
0,25 336 0,8 0,801006
The sample size is for each group.

Oh, thank you so much for responding to my post. I have been afraid to post for almost two years now since only that idiot Stan responded to my first post.
I’ll be posting up a storm now that I have my confidence back. -

If your process is the result of a sisxsigma (or ninesigma) program, then yes, you can write a book. If not, be careful about the performance of your process, because if you hire a belt she/he’ll show you how many improvements you still can do.

Does anyone have the calculation in excel for PPM to sigma.

Van Loon replied to the topic transactional lean six sigma in the forum General 17 years, 7 months ago
Okay Stan…I’m not going to argue….because I agree with everything you just posted. In certain ways, I was trying to say about the same thing, but this post of yours said it better than I could have. So perhaps I wasn’t “completely uninformed”, as much as I was failing to get my point across.

Stan wrote: Which tools do you use differently?
A number of folks have brought this up. In a way it was a miss-speak. There are a variety of tools used during the various stages of 6s. The tools used will depend on the stage, and the circumstances. A process is a process, however, if all you have is a hammer everything will look like a nail. The…[Read more]

Stan wrote: I did not call the question stupid, I called the term stupid.
As far as your answer to the % question, I will not call you answer stupid either – just completely uninformed. Transactional is not the stuff in the office (or carpet as you said). It is all of the stuff that is not actually transfoming the product and it is about 60% in… -
Van Loon replied to the topic transactional lean six sigma in the forum General 17 years, 7 months ago
Alright, I will concede to remove the “far”. The point is that you can’t use the same tools the same way for transactional processes, just like you can’t use the same tools for a continuous flow process, as you would for a single part process. One size dont fit all.
Yes, perhaps far was stretching it a bit far. -
Van Loon replied to the topic transactional lean six sigma in the forum General 17 years, 7 months ago
Here is why I say it is not drivel, and it may be just a matter of perspective. Although I would agree that to a certain extent, trying to compartmentalize the issue might be a simple word game, the question asked was a real question. For someone with no lean, or 6s background, there is a lot of confusing stuff out there. Not everyone who visits a…[Read more]

I don’t think it is drivel. However, I think you might not be grasping what we’ve been saying, and that’s okay. Transactional relates to the process. It describes a type of process. Lean is a way of thinking, a philosophy. Six Sigma describes a methodology.
A “lean” project may involve any number of tools; value stream mapping, 5-S, etc. They…[Read more] -
Van Loon replied to the topic transactional lean six sigma in the forum General 17 years, 7 months ago
Okay, let’s break this down:
1) Transactional: A process that is administrative in nature, as opposed to manufacturing.
2) Lean: A philosophy that attempts to remove waste from a process.
3) Six Sigma: A problem-solving, analysis and project management methodology to lower process defects.
Put the three together, and you get a methodology to…[Read more] -

Becoming a BB is should not require a larg organization. There are many organizations that offer BB. Some require a test, and most require some form of classroom training followed by at least one project. If you are an entrepreneur, then you might want to hook up with a smaller company that can use the SS methodology, and perhaps even do the…[Read more]
