Ahntastic Adventures in Silicon Valley Six Sigma deals primarily with elimination variation to improve production processes and product quality. Figure 5 shows the results with the same starting point as Figure 3 (average = 0, standard deviation = 1, USL = 3, LSL = -3). This is what we might refer to as the Six Sigma state. To check if a BPO company is utilizing a Six Sigma process, we compute for the three main components: defect, opportunity, and defect rate . So, lets follow us carefully. Step 1: Select the data that you want to use to construct the histogram. So, it is very important to learn how to calculate sigma in Excel.
