Both methodologies focus on improving processes and increasing efficiency. But they have different approaches and goals. Let's look at the main differences between the two methodologies.
Six Sigma is a methodology focused on reducing variability and errors in processes. The main goal is to achieve almost perfect quality. It uses data to identify and eliminate the causes of defects and errors. This methodology was developed by Motorola in the 1980s.
You can read more about Six Sigma in the article Six Sigma method and its benefits.
Lean Six Sigma combines the principles of Lean Management and Six Sigma to create a comprehensive approach to process improvement. While Six Sigma focuses on reducing variability and defects, Lean focuses on eliminating waste.
The choice between Six Sigma and Lean Six Sigma depends on the specific needs of your organization. If your primary goal is to reduce variability and increase quality through statistical analysis, Six Sigma may be a better choice. If you are trying to improve overall process efficiency, reduce waste while improving quality, Lean Six Sigma may be the ideal solution.
Regardless of which methodology you choose, both approaches can make a significant contribution to improving your organization's performance. Investing in training and certification in these methodologies can pay off in the form of better product quality, higher process efficiency and more satisfied customers.
