    @cseider – I assumed that if the number of factors was already down to 3 or 4 that a screening design had already been run to weed out inconsequential factors.

  • @jpelentrides – are there common types of defects/scrap? Instead of looking at parts/products, I would look at types of defects being created.

    @Brendans14a – I assume by “2k” you mean a two level full or fractional factorial design. By adding center-points you can evaluate for curvature. You can even use this information to create a surface plot. The advantage of a CCD is that the “star points” extend outside the region of the corner points, which provides better understanding over…[Read more]

  • @mparet – this looks like a question for you.

  • @sharatpavanreddy – why are you asking? What do you think?

    This looks like a homework question. We don’t do homework here.

  • @JohnnyV – you perform a Gage R&R on a measurement system. If the tool and people are performing the same measurements (low flow, high flow for example) you only need to perform one GR&R. So from your description it looks like you need 3 GR&R’s – for torque, pressure (including the delta p’s), and flow rate.

    @pprendeville – unless you are a masochist (or if you’re requiring others to do the SIPOC, then a sadist) you should only be doing the diagram for the issue that you are addressing.

  • @lonkelm – as my friend @cseider says, do not remove unused material from the calculation. This will cause the defect rate, particularly for nested material, to be lower than other types of production that do not have inherent waste. There is no way to perfectly nest cut parts, so some waste is inevitable. However, leaving the waste included in…[Read more]

  • @JohnnyV – My original guidance may have been a bit hasty. Are you trying to do a Gage R&R on the test stands, or evaluate the differences between the test stands regarding flow and torque? If the former, then guidance from my friend @cseider would be correct. If the latter, then my original post is correct.

    @cseider – or flies with Harrison Ford ;-}

  • @rbutler – I still don’t understand why the posting.

  • @richardkick – four years late, and several answers already posted.

  • @abyola – what are you considering “soft savings?”

  • Avinoam – If you have attribute data (it is a judgment not a measurement) then you are conducting an attribute agreement study. I suggest you search for and study how to conduct this type of examination.

  • @sharatpavanreddy – why don’t you provide your thoughts and rationale and we will comment.

    @pprendeville – treat an entity as a supplier when they are providing you something, and as a customer when you are providing something to them.

    You are trying to do too much with one SIPOC. This issue that you identify should not be a problem. You should only create a SIPOC for one specific process (or step in a complex process). Even if…[Read more]
