Analysis demonstrates improved cost-efficiency in manufacturing systems using quality control measures, indicating economic benefits.
The cost-effectiveness of manufacturing systems in Ghana is a critical aspect for understanding economic development and industrial competitiveness within the region. A multilevel regression model is employed to analyse data collected from multiple levels including individual factories and regional contexts. The model includes fixed effects for factory-specific variables and random effects for contextual factors. The analysis reveals that the presence of robust quality control measures significantly reduces production costs by approximately 10% compared to those without such controls, indicating a clear theme of cost-effectiveness improvements through systematic interventions. This study demonstrates the effectiveness of multilevel regression analysis in quantifying and understanding manufacturing system efficiency across different scales. Adoption of quality control systems is recommended as an effective strategy to enhance manufacturing cost-efficiency in Ghanaian industries, contributing to economic growth and competitiveness.
