  • @cseider Just for clarification are you suggesting not check nor fixing the measurement system and just running nonparametric tests instead?

  • @rheaestrael Probably not much different answer than @Robert Butler or @cseider. You take everything you can get as far back as you can get it and plot it. No nonsense control chart stuff just a plain time series plot and look at it for patterns, trends, runs, shifts and cycles. Then you mark the things Robert suggested where the process has…[Read more]

  • @cseider Let’s see if I draw a line and mark 0 then mark off 1-10 at equal intervals on the line and then mark 3, 4.5 and 6 I might get a clue. 2 years, 4 months ago

  • @Youssef_DO The advice about measuring emotions is a good start but mare complicated than that. You need to have a measurement system that is precise and accurate. That is MSA. If you cannot apply MSA and get an acceptable result on the analysis then you are wasting everyone’s time trying to apply Six Sigma.

    There is a reason that rulers are not…[Read more]

  • You need to take this a piece at a time, Start with you last question “moreover is 6 standard deviations greater or lesser than 3 standard deviations in the normal distribution?” If you cannot answer this or understand this then the discussion od control limits and spec limits will never make any sense to you. 2 years, 5 months ago

  • tapiseniryan That is a question that sounds very profound on some esoteric level. What does it actually mean? Let’s say we do some research and find out that your bachelors degree in a particular subject has an average placement rate of a certain percentage. It has a mean starting salary with a standard deviation. There should be benchmarks that…[Read more]

  • @straydog Definately agree on the amount of work in a QFD from scratch. Not only a lot of assumptions but also the team just gets weary because it is like a very long beating that just won’t stop. I am not a big fan. 2 years, 5 months ago

  • @cseider I have heard the one bite at a time as well. If you remember Brad from South Africa he used to say “invite the whole village.” 2 years, 5 months ago

  • @straydog I started lockdown on March 16. I am on box #3. There is a lot of interesting stuff in those boxes. Actually I thought if I had a high volume scanner I could scan everything 100% and throw it all out faster than what I am doing right now. Books are worse. I have a book from third grade. Now I can’t throw it away or donate it because I…[Read more]

  • @Straydog The 5S is great advice. My wife was working at home for about 6 weeks and that was the first thing she did. Now she has a very nice little nest to work from. I stay away from recommending 5S because it is difficult for me to do. The minute I start to sort I find a lot of very interesting things I have been looking for, for years and I…[Read more]

  • @Timmaaay I don’t normally say anything after Robert @rbutler posts because when it comes to the numbers you aren’t going to get better advice that what you get from Robert. He has this down pretty solid and he understands application not just theory.

    I am not trying to make excuses for who ever wrote the WI. You might want to check out the…[Read more]

  • @saran2383 #1 and #2 are a great start. #3 has nothing to do with Six Sigma. At what point di anyone ever tell you Six Sigma was about an “expert opinion” or worse multi-voting?

    If you are going to take the time and effort to do #1 and #2 do it the way it is meant to be done take data, analyze the data and come up with a solution that the data…[Read more]

  • @Gill.92 There are at a minimum two areas you need to consider. The first of course is the VOC (Voice of the Customer). Asking other people, even SME’s, may be good directionally but you need to speak directly to your customers. Two reasons specifically. First unless you were part of getting the input from the SME you have no idea how they arrived…[Read more]

  • @Rumbero65 You make the assumption that the person loading the parts has no effect. There is probably a good chance you are correct. Just to be sure I would run a hypothesis test just so you have it in your back pocket in case someone asks.

    We have had situations like this frequently. I am not sure I am exactly clear on how the test is set up but…[Read more]

  • @frecia3003 Isn’t part of the thesis process learning to do research? As you can see if you think this is like Seri you get zero response. 2 years, 7 months ago

  • @TracyWiggins Lets be clear about your question. Are you asking about managing a project as in a DMAIC project or are you asking about managing a Process Improvement Program (multiple projects).

    If it is just a project Straydog is dead on. 2 years, 7 months ago

  • @sanchanmodi Why would your first response be to widen the specification? What made you ask that? 2 years, 7 months ago

  • @Alessione welcome to the group 2 years, 7 months ago

  • @HV1234 I am not sure I understand this completely but let me see if I can help. It has been a very long time since I have used GD&T. When you say that >/= 1.0 is good and 0.5-1.0 is also then in terms of a Cpk they are both within specification. That is about the extent of what you get from Cpk. It really doesn’t explain degrees of goodness. It…[Read more]

  • @amrlord I am not sure what the point was to the long diatribe but since nobody else wants to answer you I will take a shot at it. Participation in Continuous improvement is not gender, religion, nationality, race, etc. sensitive. The younger generation issue doesn’t change first principles, mechanical engineering, etc. There are courses out there…[Read more]
