The aim of this study is to apply six sigma in assessing variation to reduce non conforming net weights of bar soaps in a local soap manufacturing enterprise. The Six Sigma DMAIC define, measure, analyze, improve, and control quality improvement methodology was used for this study and a Digital Electronic laboratory weighing balance 5000g 0.1g was used in weighing the various samples to obtain data for study, while Minitab software 20 was used in carry out all the analysis. From analysis, the population mean of the bar soap net weights was discovered to be within 67.3 and 68.4grams which is below the declared net weight of the product. Critical To Quality Characteristics CTQs were identified and improved upon and when deployed in the production process, improved the bar soap net weights population mean to 71.4 and 71.9grams. To check the final stability of the improved and prevailing net weights, the mean and standard deviation of the improved process was used to run a simulation study and the X bar ”“ S chart proved that if present conditions are maintained, the manufacturing process will churn out consistent bar soap net weights of 70 grams which will leave customers satisfied and also meet the regulatory requirement of NAFDAC. The study concluded that the Six Sigma is disciplined, focused and scientific problem solving technique, which uses statistical and non statistical tools integrated with methodology to bring down number of defects to 0 3.4 defects per million opportunities in any process and thus recommended for business and researchers who wish to improve their products and services.
