Many quality management techniques in the industry sector have been applied over the past decade. Continuous improvement was most common because of its unique ability to provide businesses with competitive advantages. Six Sigma (SS) has been a popular method of continuous improvement to enhance the operational efficiency of an organization, raise its profitability, and decrease its costs. Therefore, quality improvement has been the most sought-after term for many years, addressed not only in large companies, but also in small industries. The implementation of this powerful tool has not only decreased the defect level, but also in product development, customer retention evaluation, cycle time management, improved productivity, and market share.
