What is the focus of Six Sigma according to its critics?

The focus of Six Sigma, according to its critics, is often seen as preventing problems within existing processes. Six Sigma is a data-driven methodology that seeks to improve process quality by identifying and removing causes of defects and minimizing variability in manufacturing and business processes. Critics argue that while this focus on problem prevention can lead to improved efficiency and reduced defects, it may neglect other important factors, such as employee involvement and innovation, which are crucial for overall organizational growth and adaptability. This viewpoint highlights a potential limitation of Six Sigma in addressing broader business-related issues beyond mere process improvement.
