The need to optimize the triangle formed by “quality, cost and time” culminated in increasing the focus from product to process quality. By analyzing the evolution of quality and the impact of Industry 4.0 on it, this research seeks, through a technical point of view, to comprehend the state of the art of quality 4.0 and intelligent quality management (IQM) by defining concepts, technologies, challenges and applications.
The review was conducted only in English, on IEEE Xplore, Scopus, Engineering Village and Web of Science databases with a backward citation analysis, having technology and quality as main concepts. In total, 109 papers were reduced to 24, and 11 characteristics were extracted.
Although many authors point to the same 4.0 technologies and the importance of quality for Industry 4.0, they differ in the concept of quality 4.0 and the implementation frameworks to achieve it.
This paper is one of the few studies that have searched for the roots of quality 4.0 and IQM. The work also seeks to identify their differences and their relationship with Industry 4.0.
