Six Sigma primarily focuses on which of the following?

Six Sigma is a disciplined, data-driven approach primarily aimed at improving the quality of processes within an organization. This methodology emphasizes reducing variability and defects in processes, which naturally leads to superior quality and, accordingly, lower operational costs. The primary goal is to enhance efficiency by identifying and eliminating sources of errors and inefficiencies, ultimately resulting in products and services that meet or exceed customer expectations without incurring excess costs.

By focusing on quality improvement and cost reduction, Six Sigma enables organizations to deliver higher-quality products more efficiently, enhancing overall customer satisfaction and organizational performance. This focus on operational excellence underpins the effectiveness of Six Sigma as a quality management strategy. The other options touch on important aspects of business but do not capture the core emphasis of Six Sigma as precisely as the correct answer does.
