Paper Title
Reduction of Defective Parts of Oil Seal Production using Six Sigma Methodology

The main objective of this analysis is to improve the efficiency of oil seal production. Since defective products is considered as one of the main factors contributing to the magnitude of production efficiency, it is being considered as the factor to be reduced. This is performed by employment of lean six sigma which is a well known tool for problem solving scenarios. The DMAIC methodologies aids in understanding the flow of process and detection of flaws in such manufacturing processes. Keywords - Six Sigma, Bar Chart, Lean Manufacturing, Statistic Process Control, Cause and Effect Diagram Case Study - This paper about a production firm which is producing oil seals in mass quantity. It also focuses on the quality of the oil seals. Oil seals are being employed between stationary parts and moving parts in order to avoid leakage of lubricant.
