The existing quality definition established by the authority mainly based on J. M. Juran is "quality is the degree to which a set of inherent characteristics fulfills requirements". Among them, "requirements" can be an individual's requirement and there is no positive restriction, and there are no restrictions on motivation . A high degree of meeting unreasonable requirements can also be called good quality. The judgment of the degree to which individual consumer demands are met is subjective. In this way, the quality definition of Juran can only be subjective. At least the two major shortcomings of subjectivity and lack of enthusiasm in existing quality definitions must be overcome. As long as the "requirements" in the definition of Juran’s quality are limited to objective social general requirements (which are also positive requirements), the goal can be achieved. The definition of Juran’s quality naturally became "quality is the degree of positivity". The new definition of quality has positive guiding significance for management theory and practice.
