Q uality is a subject`in fashion' : m any top m anagers are giving this matter greater im portance now ; many gur us are providing their precepts for m aking quality; many managers attend several seminars on quality looking for`cooking books' . Actually, quality is a serious and diý cult business; it has to become an integ ral part of managem ent. Too m any com panies are well behind the desired level of quality management practices. M anagers need to lear n and put into practice quality ideas. T herefore, som e important principles are: relationship between com petitiveness and quality, management and quality, m anagement by if . . . then . . . else, scienti® c approach, intellectual honesty, quality integrity, the three quality identities, the rational m anager, TQM 2 , FAUSTA VIA, etc.

Abstract:The document shows the ideas to overcome the deep ignorance on the CI (Confidence Intervals) and on DOE (Design Of Experiments); the first part poses the problem that was originated in the RG (Research Gate): it analyses few of the answers, found in the forum, AND some wrong ideas one can find in Wikipedia; connection with the Test of Hypotheses is given; some figures are provided that make "intuitive" the concept of the Confidence Interval with the Theory (Classical Statistics). The second part considers some cases one can find in a very WWU (World Wide Used) Book: we show that high scores on documents do not prove the Quality of those documents. This paper is especially written to settle the matter for the researchers who use CI and DOE: Researchers must be alert in order to do a good job…. Many others cases should be shown: the paper should be 10 times longer; to make the paper shorter … I had to cancel pages providing the ideas on the "Scientificness", forgotten by many people and other providing ideas misleading the readers taken from Wikipedia.

Abstract:We show an application of the SPQR Principle [«Semper Paratus ad Qualitatem et Rationem ("Always Ready for Quality and Rationality")»] as the way to analyse papers and books; it seems that very few people have taken care of Quality of Methods (Deming, Juran, Gell-Mann, Shewhart, Einstein, Galilei). The case analysed here is about a Design of Experiment application to Large-Scale Metrology and to Control Charts.
