Common sense strikes back…
Working on PIUSS PMAI found a phrase rather interesting "Common Sense is the least common of the senses" (better reference it just in case....(Pande, Neuman & Cavanagh ; 2000) ). It relates to my old post saying that most scientific knowledge I saw in my life in economics, finance, engineering, quality, process and so forth are organised and well presented common sense.
6 Sigma is no different. Common sense all the way. Even though I must say that the way it is presented, the toools, the way priorities are defined do stimulate some thinking that we don`t usually do. I realisedsome colleagues are having trouble perceiving the whole logic of thinking on a process and variation related way, and that what 6 Sigma can help with, to show the importance of understanding that logic and presenting a way to relate it to everyday practises and results. So it is a clever way to stimulate and take results out of common sense.
So if I had to say what is the most important aspect of 6S, the one you should really understand it would be: "Pay attention to processes, look at them carefuly and sistematically and take as much variation out of it as possible".
But when the concepts are understoos, it is common sense ain`t it?
