The purpose of this study is to determine the underlying magnitudes of manufacturing practices and to empirically test a structure pinpointing the interactions between manufacturing practices and operational performance, namely cost, quality, speed, and flexibility. Statistics for this paper was composed from a sample of a steel manufacturing company in South Africa. The research framework was tested using structural equation modeling approach. Based on probing factor analysis, manufacturing practices were gathered into two factors: manufacturing strategy implementation and operational performance. The results indicate that two practices have direct positive and statistically significant impact on operational performance. Likewise, this study tried to scrutinize the best apt model between manufacturing practices and operational performance.
