Which of the following is an example of quality assurance in a Six Sigma project?

The focus of quality assurance in a Six Sigma project is on ensuring that processes are in place to maintain and improve the quality of products or services. Option A is an example of quality assurance because it directly addresses the need to minimize quality defects, thus ensuring that the outputs meet predetermined quality standards. This proactive approach aims to monitor and control the processes to maintain quality, which is a critical component of quality assurance.

By concentrating on reducing defects, the project not only aims at achieving a higher level of customer satisfaction but also reinforces efficient processes that contribute to overall quality improvement. This aspect of quality assurance helps in preventing issues rather than just correcting defects after they occur, adhering to Six Sigma’s goal of reducing variability and defects.

In contrast, the other options focus on operational improvements that, while beneficial, do not specifically target maintaining or enhancing the quality levels of products or services. They may address cost reductions or efficiency gains, but they lack the direct emphasis on ensuring that the output quality remains consistent and high, which is the essence of quality assurance in the context of a Six Sigma project.
