Book excerpt: Discovering and externalizing of the quality concept and its measurement became the main focus of his research for many years. In 1996, after the collapse of the socialist system, he immigrated to the United States. Haxhi is a member of the American Society for Quality and a team member of the QTI Inc. in Chicago. He published the book Quality Quantification Theory: Economy Goodtime Measurement System (which is the first part of this book) in 2010. The concepts of quality, or goodness, and other related concepts, such as good, well-being, and general welfare in the political, economic, and social sciences, have not been accurately defined. Their meaning has been taken for granted. The reality is that these concepts, hidden in the mind of each individual, are known by the brain but have not been expressed in language. In this book, the author discovers and codifies the mysterious concept of quality. Reformulating what we believe to be the concept of quality is the starting point of a conceptual revolution in understanding and governing humanity.
