What aspect does Lean Six Sigma primarily focus on reducing?

Lean Six Sigma primarily focuses on reducing variations and waste in processes. This methodology combines the principles of Lean, which aims to enhance efficiency by eliminating waste, with Six Sigma, which emphasizes improving quality by reducing variability in processes.

By targeting variations, Lean Six Sigma seeks to create more predictable and stable processes that ultimately lead to improved quality outcomes. Waste reduction is equally critical, as it streamlines process flows and enhances overall productivity. By focusing on these two key areas, organizations can achieve both higher efficiency and quality, leading to greater customer satisfaction and overall performance.

On the other hand, while adjustments to workforce size, product range, and material costs may be involved in broader operational strategies, they do not directly encapsulate the primary focus of Lean Six Sigma, which is specifically concerned with refining processes to minimize waste and variability.
