I, like many others I guess, fell into the trap of thinking that there is only one way to calculate standard deviation. Clearly I need a deaper understanding of the underpinning statistics when attempting to evaluate process capability and pe…[Read more]

    Can somebody please answer the bit about Pp and Ppk since I think this gets into longer term process performance and process shift. I have continued arguments about this with colleagues since all mechanical processes wear out.

But as we are enjoying probably the deepest recession in the UK in history, I’m game for making any worthwhile savings in waste. So if senior management buy into all this carbon footprint stuff, lets go with it and use our scientic kn…[Read more]
