Six Sigma Quality Improvement
Achieving Quality through Continual ImprovementThere exist two troubling trends faced by the plastic beverage container division or Riordan Manufacturing. The overall results of the trends are lowered levels of customer satisfaction, and higher overhead costs. These trends are to be measured and analyzed in order to recommend a viable solution. This analysis of the process is very important to Riordan Manufacturing's strategic plan. An outline of the quality improvement for this process will be fully explained. Recommendations and basis for further investigation also accompany the analysis.
Target ProcessRecent developments have led to focus on one particular area of the plastic beverage container molding process. A marked increase in bottle rejects due to fluctuation in finished volume has lead to a heightened level of scrutiny on the process. A recent increase in the level of customer complaints due to the same inconsistency found to be inherent in the volume of the finished product. Our engineers have been directed to implement a new system by which to identify the root of the inconsistency. This will allow for the mitigation of the inconsistent volumes and provide for the most cost effective solution while maintaining the highest level of customer satisfaction.
Process DescriptionThe following is a high-level breakdown description of the blow molding process by which the plastic beverage container division manufactures the subject containers.
