Process Standardization, Cost Control Practices, Quality Assurance Practices, Operational PerformanceAbstract
This study aimed to examine the effects of process standardization, cost control practices, and quality assurance practices on operational performance in automotive manufacturing firms in Thailand. Data were collected through a structured questionnaire administered to middle-level and senior managers, or managers responsible for operations, production, quality, or cost management, each with at least five years of professional experience. The organization served as the unit of analysis. Purposive sampling was employed, yielding a sample of 300 organizations. Data were analyzed using hierarchical multiple regression analysis. The findings revealed that process standardization, cost control practices, and quality assurance practices had significant positive effects on operational performance. Among these factors, quality assurance practices emerged as the most critical mechanism for enhancing overall operational performance. The findings underscore the importance of systematically integrating operational management practices to strengthen the competitiveness of automotive manufacturing firms in Thailand. Such integration contributes to improved production efficiency, product quality, delivery reliability, and cost control. These findings provide valuable insights for managers and practitioners seeking to enhance operational performance and sustain long-term competitive advantage in the automotive manufacturing sector.
