  • Try working with a social organization you already are a participant.  I’m sure every organization could use some volunteer talents. 10 months ago

  • It seems you do have a UCL. :)

    hope all is well with you @rbutler ! 10 months, 1 week ago

  • Consider looking up Z normal tables versus sigma and check out tables that don’t “shift” and then consider you will have SOME defect rate at both ends of the curve and add. 10 months, 4 weeks ago

  • I’d highly recommend the beer exercise and other VERY basic lean concepts/training before having them do an exercise.  Also, do you have a champion for such production layout you are proposing? 10 months, 4 weeks ago

  • @katiebarry  great advice to contact them directly about the calculator.

    hope you and your family are staying safe! 10 months, 4 weeks ago

  • Nice idea for the 5S number exercise, @danroth 11 months ago

  • @rbutler you are kind to help with homework. :)

    Stay safe and hope your family stays well! 11 months ago

  • Color measurement exists.  Maybe see if you can get a variable data measurement device/panel and not have a scale.

  • No.

    However, I’d suggest you consider attaching a pdf or link or web address for link.  Hard to see what you are generating buzz about. 11 months ago

  • If you can come up with a project sheet with metric and problem statement, etc., then that would go a long way.

    There are always defects in processes but find metrics with business impact or safety impact and that helps out a lot. 11 months, 4 weeks ago

  • @Distocont the value of a rating scale depends on your reason for collecting the data. If you are only trying to understand what your reject rate is, then a rating scale has zero value. However, if you want to use the data to improve the process, then a rating scale in many cases can have a lot of value, provided you can rate the severity of the…[Read more]

  • @lucaspaesp – a lot of good discussion here, and I hope you’ve learned some things.  Fundamentally, you have a measurement system that doesn’t have sufficient precision.  There are several techniques that I might suggest, but the easiest is to use the raw data instead of sub-groups (as it seems you plotted in your graph #2). 1 year ago

  • @Mike-Carnell – and don’t get me started on the whole “1.5 sigma shift” bullshizzle. 1 year ago

  • @cseider – so, you’re telling me it aint?  Oh, I get it, +3 and -3 must be Zero sigma ;-} 1 year ago

  • @rbutler – Big Brother is always watching ;-} 1 year ago

  • @rbutler – and simple algebra at that ;-) 1 year ago

  • @irfan.ahanger01 – I’m certainly not going to disagree with @rbutler (good to see you’re still here, trying to educate the masses!), but I would take a more pragmatic approach.  You already have a design with the center points, so you need to add the Star Points.  For each factor, you will need two – a high and a low, set at an alpha level – to a…[Read more]

  • @AR19CHU91 – you might get more of a response if you posit some of your own perspectives instead of just throwing something out and asking for comments.  As I have said here many times (albeit not recently) – do your own homework. 1 year ago
