The primary goal of implementing Six Sigma methodologies is to reduce process variation. Six Sigma focuses on identifying and eliminating defects in processes by reducing variability, which ultimately leads to higher quality and increased efficiency. By systematically analyzing and improving processes with a focus on data-driven decision-making, organizations can achieve more consistent and predictable outcomes.

Reducing variation is crucial because it directly affects the capabilities of processes, the quality of products or services, and customer satisfaction. When a process operates with less variation, it can produce results that meet customer expectations more reliably, thereby enhancing overall performance and reducing costs associated with defects and inefficiencies.

The other options, while they may have value in organizational contexts, do not capture the essence of Six Sigma methodologies. Increasing product variety may not inherently reduce defects or improve quality, improving employee satisfaction is a beneficial outcome but not the core focus of Six Sigma, and maximizing production speed without addressing variation could lead to a deterioration in quality. Therefore, the emphasis on reducing process variation distinctly defines the primary goal of Six Sigma.
