This research examines the implementation of Total Quality Management (TQM) in Peru based on nine factors. The questionnaires were sent in 2006, 2011 and 2017 to the presidents and managers of Peruvian companies. The objective is to study the evolution of quality in Peru. The results showed an improvement from 2006 to 2011; in 2011 and 2017 the companies maintained a steady state result.. The Quality Management System (QMS) is a key element used to explain a statistically significant difference in two factors for companies that have implemented or not from 2006 to 2011. However, the studies conducted in 2011 and 2017 had significant differences in all success factors. The contributions of this paper are: (a) Information on TQM factors in Peruvian companies in more than a decade; (b) a comparison in three periods (2006, 2011 and 2017) about the implementation of TQM in Peru and (c) the identification of the areas that Peruvian companies need to improve if they want to be more competitive.
