With the general objective of process improvement and fewer faults, Six Sigma is a collection of methodology, tools, and procedures. Click on to learn more about the Six Sigma approach. By creating high-quality products, Six Sigma aims to please clients. Thus it concentrates on reducing variation and getting rid of waste. Increased effectiveness results from this.
The variance is the range of differences between all of the data points needed to calculate the statistical mean and the statistical mean itself. Or, the amount by which process performance deviates from the mean. Waste or faults are quantifiable product attributes that fall short of client expectations (i.e. defective products). In other words, any process performance that deviates from the established standard is viewed as waste or an error.
