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

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

  • 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. 1 year, 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. 1 year, 12 months ago

  • Always attack the constraint IF you need more capacity or the possibility to assign labor to other “lines” or processes so overall labor cost drops because fewer shifts or hours are used to produce the same amount of product.

    However, defects may have a higher cost impact than lost sales–heresy, I know, that sales can’t sell everything made if…[Read more]

  • Sadly, I saw study materials from a course at a university MBA program state that 6 sigma is because of the +/- 3 sigma.  Amazing how diluted the teachings are from the early 90s.

    I wasn’t in the class but told the student that wasn’t six sigma meant.

  • I’d say fix the measurement system.

    Just saying AFTER fixed, it would probably allow the Anderson Darling test to come to another conclusion. 2 years, 2 months ago

  • @mike-carnell “what about 4.5 sigma”?  :) 2 years, 2 months ago

  • the correct ones?

  • If you followed the DMAIC methodology you would have checked your measurement system.  My educated guess is it won’t pass a good variable gage R&R.  This is PART of the reason your normality tests are failing but don’t fret too much if it doesn’t pass…median shifts are just as valid for statistical confidence–yes I know how my friend R. B…[Read more]

  • Have you considered following the classic DMAIC process?  You should already have gathered data on some of the X’s and looked for POTENTIAL/PROBABLE X’s in the measure/analyze phases.

    If you are trying to create a DOE and can’t get support–are you 1. making sure the process participants are part of the team and 2. giving updates to the team and…[Read more]

  • Yes, your service industry definitely has many peaks and valleys–especially if in the retail arena.

    Some thoughts to consider

    1.  How “easy” is past data for the metric that was agreed by the project sponsor/project leader?  If easy, see if any sign of seasonality and that may help you decide on what time frame for getting an average or s…[Read more]

  • Control charts are great…just always don’t folks to think they are doing capability analysis on means which is where CLT applies.  Capability analysis is always done on individual readings. 2 years, 3 months ago

  • I think you’ve forgotten an important thing.  Do a gage R&R for both devices before going first. 2 years, 7 months ago
