Abstract
This paper examines the components of quality cost (internal failure, external failure, appraisal cost, and prevention cost) in the context of two key manufacturing inputs, materials and machines; the concept is also explained for the company as a whole. The purpose of this research is to analyze the variables that impact quality in a manufacturing environment. There are three major findings in this research. First, there is an inverse relationship between appraisal cost plus prevention cost and failure cost. Second, the relationship between appraisal cost plus prevention cost and quality is positive. Finally, failure cost is negatively correlated with quality. This analysis also revealed a strong relationship between appraisal cost plus prevention cost and quality for material input, machine input, and the company. The results indicate that as the appraisal cost plus the prevention cost increases, quality improves and failure cost decreases.
