• I agree with @Straydog – the issue is that of statistics.  If we assume you have a mathematical background that includes algebra and if, for whatever reason,you can’t take a course in basic statistics then I would recommend working your way through the following books:

    1. A Cartoon Guide to Statistics – Gonick and Smith – I’ve recommended this…[Read more]

  • @Straydog is correct – no subgrouping here just the individual data points.  Once you have a histogram built as he recommended (I’d also recommend plotting the data on a normal probability plot) post the graphs here and perhaps I or @Straydog or someone else may be able to offer additional thoughts. 1 year, 11 months ago

  • @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 ago

  • I agree with @Straydog that Lean Six Sigma and ISO are very different things. However, they are related. As @Bagan says, there is a place for LSS within ISO. LSS is a way to achieve greater levels of excellence with the ISO management system. But there is also a place for ISO with LSS. Namely, in the Control phase of DMAIC. The control phase is…[Read more]

  • @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]

  • @Straydog, thanks for the input.  A PFMEA and DFMEA have already been drafted and that is what is driving the specified C/R level.

    Control limits are calculated at +/- three sigma from the mean.

    makes NO sense, for Exponential or Weibull distributed data!!!!

  • @Tipman – I’m going to disagree with @straydog that creative people are likely to resist.  My experience is that they need to be shown how various tools help them to do what they inherently know they need to do.

    I’m not sure just what you are having trouble with.  Is it identifying new items to pursue (you will need tools that foster i…[Read more]

  • Thank you everyone for your insights, experiences, and advice. @rbutler seemed to hit the nail on the head with his experiences because I usually get a call after the project is falling apart and they need a “saving grace” with a “quick fix”, unfortunately I don’t usually come up with a quick fix and that is when the trust in what I do is…[Read more]

  • Thank you very much for your response @Straydog, I totally agree with your point of view of how we can improve the harvesting process. Nevertheless the Managers want to this measure become a KPI in the near future, is going to be measure frecuently, so we need a Sampling Procedure to determine the areas. 2 years, 6 months ago

  • @Straydog, I know very well what is (and it is much more valuable of a “simple” calibration) and the importance of MSA and I do push all my trainees and coachees to use it, but on the other hand I also convey the message to not “overprocess” projects where there is not a real need to use a specific tool and from what I could realize about…[Read more]

  • Thank you so much @straydog. I appreciate it. 2 years, 9 months ago

  • @Straydog This goes back to 1996 and was a military contract. I have to watch exactly what I say on this. Two parts were glued together and the assembly was 100% defective. Management wanted it fixed and formed a team that one of our people was meant to facilitate. Luckily we chose a very kind and friendly person for this task. After couple team…[Read more]

  • @chebetz, @rbutler and @straydog Just to do one upsmanship I found this site in 2001. I was being sued for violating a noncompete so I couldn’t work for myself. The guy suing me used time as a strategy and dragged these things out trying to run you out of money. It also gave the market time to forget you and move on. I dedicated 4 hours a day to…[Read more]

  • Well @Straydog and @Mike-Carnell that guy @chebetz has found us out!  I guess it’s time we ask Mike Cyger to tell Katie to change our screen names again. I think I’ll go with Dr. Theodore Sabbatini this time around.  :-)

    I can’t answer for Straydog or Mike but given our interactions over the years I’m pretty sure their answer will be the same a…[Read more]

  • @rbutler, @straydog, @mike-carnell – Thank you all for your responses.

    Gotta ask: You guys seem to respond to most questions I’ve seen posted on this forum. Is this your day job or something? Do you guys sit around all day answering people’s questions on this forum? Every time I’ve posted a question, I know I can count on getting a response from…[Read more]

  • @chebetz I am with @rbutler and @straydog on some level. There is no statistical jail. You want them on there put them on. Don’t put them on and walk away. Pay attention to what you have done and make sure you aren’t causing a mess. This whole thing is about continuous improvement. You want to try something, do it and if it works keep doing it and…[Read more]
