Reducing variability in process and the risk of product defects: A case study in SME's

Abstract

The study aims to determine the quality control level of mineral water packaging. Six Sigma is recognized as an essential tool used in this study in determining the quality level by measuring variability in the process, reducing product defects (packaging), and developing the improvement comprehensively. The implementation of Six Sigma has been implemented in many advanced companies. The implementation was conducted in one small-medium enterprise (SME) that produced the mineral water. However, the implementation of Six Sigma in the small-medium level of industries has relatively new challenges. The result showed that identified four defects: Bottle cover defect, bottle defect, label defect, label, and process defect. The process variability was highly fluctuated and identified about 28 data out from control lines. Based on the capability process was measured and gained sigma level in 3.76. Some recommendations were set to reduce the variability of the process.
