Abstract

Attending seminars, Conferences, looking at "television lessons" the author saw many times many people (often Professors) that did not know the matter they were talking about [as Deming wrote "the 1st requisite for a good teacher is that he have something to teach#x2026; must possess knowledge of the subject"]; nevertheless many of them still write papers, suggest "wrong" books to students, provide "wrong" lessons, make consultancy. Visiting Companies the author saw many times many Companies lacking Quality of Management, a big problem against Quality achievement. Many lecturers on #x201C;quality matters#x201D; and on #x201C;reliability matters#x201D; do not know, in a scientific way, reliability theory; therefore, they propose wrong methods to students. The basic reliability ideas are easily understandable, but when you need more sophisticated methods many people do more harm than good. In the paper we present a case related to contractual clauses on failures and related costs; we show that even in this simple case, the Reliability Integral Theory (devised by F. Galetto to overcome limitations on the usual methods in reliability) is needed. Companies#x2019; solutions and real applications are an important problem: wrong solutions depend on the lack of scientific knowledge.
