Can quality management make a company successful? This is a legitimate question, given all the controversy surrounding the subject. Indeed, even if the precepts conveyed by this discipline are used, remodeled and reformulated by certain authors, teachers or management seminarists, the fact remains that there is still a certain prudishness in using the word "quality" literally. For it is a word which, for many, is understood to mean quality in the sense of "compliance with standards".This book has been written to demystify the word and give it back all its original attributes. In a way, it's a summary of everything there is to know about the principles of quality management, which, in reality, are the only rules to be applied to boost a company.
