QUESTION THREE $[25]$ Phezulu Electronics $($PE$)$ is a manufacturer of high$-$precision components for the automotive and aerospace industries. Over the past year, PE has faced a rising rate of product defects, leading to increased rework costs, delayed deliveries, and decreased customer satisfaction. In response, PE's management has decided to implement a Six Sigma approach to improve quality, reduce defect rates, and increase operational efficiency. PE$$s goal is to reduce its defect rate from $2\%$ to less than $0\mathrm{.}5\%$ within six months, as each percentage point reduction could save the company approximately R$100,000$ per year in rework costs. Six Sigma Implementation Goals: $$ Identify the root causes of defects and errors in production. $$ Develop a data$-$driven strategy to minimize variability in the manufacturing process. $$ Standardize processes to ensure consistent quality and compliance with industry standards. Question Evaluate how PE could use the six$-$sigma methodology to reduce its defect rate from $2\%$ to less than $0\mathrm{.}5\%.$ Make use of examples in each of the six$-$sigma stages.
