The purpose of this article is to share the investigations we have done in six-sigma applications in improving the quality and productivity of manufacturing industries particularly in pharmaceutical manufacturing industries. The relationship between six-sigma and the ISO certification and the quality cost concepts are deeply discussed in this research for the tablet manufacturing section. Quality cost is analyzed based on the six sigma metrics and Taguchi loss function using 1430 sample size of tests before and after the company’s certification of ISO 9000 Quality Management System. Uses and application of Six-Sigma in the developing countries, particularly, in the African context is found to be limited or none in the recent literature review while the competitiveness of Pharmaceutical industries is challenged because of quality and productivity. The results obtained from the study revealed that the application of Six-Sigma in the company has proved quality improvement by minimizing the variations in the process.
