Investigating the mediating effect of quality practices on the relationship between lean practices and production fitness

Abstract

The aim of this study is to investigate the mediating effects of quality practices on the relationship between lean practices and production adequacy. This research is applied in terms of objective and descriptive-exploratory in terms of collection method. The library field method and a questionnaire were used to collect relevant information. The statistical society consisted of citizens of Tehran. Due to the lack of access to the statistical society to determine the sample size, the Cochran method was applied. In all, 384 people were selected and a questionnaire was distributed using the random sampling method. The confirmatory factor analysis method was used to determine the validity of the questionnaires. In addition, Cronbach's alpha coefficient was used to determine the reliability of the questionnaires. Descriptive and inferential statistics were used to analyze the data. The results showed that the level of investment in quality-related methods mediatizes the relationship between the level of investment in lean and uniform production methods.
