I was just reading a recent thread which mentioned CuSum charts, and it reminded me of what an incredibly useful tool they can be. For example, their ability to detect small, sustained changes means they can be applied retrospectively to data to determine whether an observed shift in process mean was sudden (step change) or gradual.
CuSums have loads of uses, and yet I would guess that most people, even those who have received some form of training on the subject, have never used them in anger.
Which got me thinking...
Of the quality tools and techniques we are exposed to, is there one that you believe is really under-rated? (i.e. it should be promoted and used much more than it is)
Conversely, are there any tools which you feel get too much attention and are subsequently relied upon more than they really should be?
So, what tools are "hidden gems", and which are more like the "Emperor's New Clothes"?
