The Effect of Japanese Production Management and total Quality Management on Reducing Production cost: a Case Study of a brass Component Manufacturing Company for air Conditioners in Pathum Thani Province.

Abstract

This research aimed to study: 1) the levels of Japanese manufacturing management, total quality management, and production cost reduction; 2) the aspects of Japanese manufacturing management that affect production cost reduction; and 3) the aspects of total quality management that affect production cost reduction. Data were collected through an online questionnaire administered to 110 production employees of an air conditioner brass parts manufacturing company in Pathum Thani Province. The data were analyzed using descriptive statistics, Pearson’s product–moment correlation coefficient, and multiple regression analysis. The results showed that: 1) the levels of Japanese manufacturing management, total quality management, and production cost reduction were all high, with mean scores of 3.50, 3.81, and 4.07, respectively; 2) aspects of Japanese manufacturing management—specifically operating standards and continuous improvement activities—jointly and significantly predicted production cost reduction at the 0.01 level, with a coefficient of determination of 42.90%; and 3) aspects of total quality management—specifically quality and process improvement and employee participation—jointly and significantly predicted production cost reduction at the 0.01 and 0.05 levels, with an overall coefficient of determination of 52.90%. The findings can be used as guidelines for implementing Japanese manufacturing management and total quality management throughout the organization to reduce production costs and promote systematic operations that support organizational stability.
