What does the Six Sigma performance measurement primarily involve?

The Six Sigma performance measurement primarily involves the computation of averages and variation, which are essential components in understanding process performance and quality. In the Six Sigma methodology, the focus is on quantifying how much variation exists in a process and identifying the mean performance level.

By measuring these factors, organizations can determine the capability of a process, identify areas for improvement, and implement strategies to reduce variability, leading to enhanced quality and efficiency. This approach helps in identifying defects and inconsistencies, which ultimately supports the goal of achieving near-perfect quality in products and services.

The other options touch on significant business concepts but are not central to the Six Sigma methodology. Cost-benefit analysis focuses on the financial aspects and may not directly correlate with measuring performance metrics. Risk assessment is related to identifying potential issues but does not specifically measure performance. Revenue optimization deals with enhancing sales and profits, which is beyond the scope of Six Sigma's primary focus on quality and process improvement through statistical analyses.
