@Aaronolson Most of the literature is going to tell you 20 or 30. We had a huge debate on this in 1999. 20 or 30 is actually insufficient as well. The real issue is nobody generally will pass an attribute agreement study first time through so why do we want to do a couple hundred samples which is where one of out consultants had determined we…[Read more]
@aaronolson I would think that to a bunch of mechanical people #4 would appeal because it is traditional. Old time mechanical measurement stuff. Also technique dependent.
This whole 1,2 & 4 thing seems to be pretty opinion based. Probably healthiest to stay out of the fight and let the data talk.
That is a lot of dies. Probably best to…[Read more]
@aaronolson I apologize on missing the part about the expert. Your measurement systems may make a straight answer a little more complicated. It looks like 1 & 2 are going to produce attribute data. That is going to be an attribute agreement type study and you will need the expert included by definition. If you go to a measurement system such as a…[Read more]
@aaronolson I assume that these are large squares? It looks like options 1-5 are going to have capabilities that are going to differ based on the tolerance requirement of the square. You might consider that you qualify the measurement system based on tolerance requirements i.e. not use a CMM if there is a tolerance of +/- 1 inch.
when I look at…[Read more]
@aaronolson Yes I have experience with them and I like both. In terms of are they useful – they are but that is really up to you. You need to build the time into your deployment to have people understand the full functionality of the tools. That is not indigenous to the Moresteam products that is pretty much any software you buy to support a…[Read more]
@aaronolson The reason I asked about the cutting operation is because if you have incomplete cuts there has to be some systemic issue in terms of an incomplete cut. If my blade travels a certain distance and over time I get incomplete cuts either the travel drifts of the blade wears down. I would start measuring the blade. Normally it wears down.…[Read more]
@aaronolson Just a quick story. Similar issue except cutting hose. Turns out the supplier of the hose can cut it automatically and did not increase our price. At some point in the past a person had decided if we cut we would save money. Now the supplier purchased reels to roll up the hose which was different than every other process he had. Maybe…[Read more]
@aaronolson It was from a while ago. I said what I had to say on that string so there was no reason to get involved again.
I like your thoughts on it just being treated as one Continuous Improvement package. You are occasionally going to run into people who call themselves “purists” but at the end of the day they are really less beneficial to an…[Read more]
@aaronolson I caught a comment you made about what you perceive as the SS methodology based on tools. SS is a thought process. It has been turned into a set of tools so people who do not understand it can sell certification. You haven’t been on this site long enough to see that what has happened to the SS industry is it has shifted focus from…[Read more]
@aaronolson I saw the suggestion for lean in an earlier post. There is a book called Lean Acres by Jim Bowie. It is probably the easiest read and most understandable Lean book I have ever read.
I gave a copy to a young woman who was in Middle School. She read it and then we had some conversations about it. She got it. 1 year, 11 months ago
@aaronolson Juran’s book called Managerial Breakthrough from 1964 is a great book to build your foundation on. You need to understand the difference between breakthrough and control.
The Deviants Advantage. Great book and a good understanding about fringe idea becoming social convention.
The Subtle Art of Not Giving a Fxxx. Aside from an…[Read more]
@aaronolson I wouldn’t worry about whether it is SS of Lean. At the end of the day if to tell someone it is SS and it isn’t nothing changes. If you tell someone it isn’t and you are wrong nothing changes. This is one of those things people will make an issue of if they don’t know what else to ask you.
I do believe you need to take a different…[Read more]
@aaronolson No, I wouldn’t change my thoughts. In project management we teach that there is a difference between functional and non-functional requirements. Functional requirements concern what the product, service, or whatever the project is developing actually does. Non-functional requirements are things such as costs, deadlines… Six sigma…[Read more]
