The key objective of a Six Sigma project is to reduce variation in critical processes. Six Sigma is a data-driven methodology that focuses on identifying and eliminating defects in processes to improve overall quality. By reducing variation, organizations can achieve more consistent outcomes, which leads to enhanced customer satisfaction and operational efficiency.

In the context of Six Sigma, variation refers to the differences in process performance that can lead to unpredictable results, impacting the quality of products or services. By systematically analyzing data and using statistical tools, Six Sigma practitioners aim to identify root causes of variation and implement process improvements. This not only helps in lowering defect rates but also minimizes waste and increases productivity, solidifying the organization's competitive edge in the market.

Overall, the focus on reducing variation aligns perfectly with the goals of Six Sigma, making it the correct answer to the question regarding the primary objective of a Six Sigma project.
