The Six Sigma method and its benefits

Six Sigma is a process management and quality improvement methodology that focuses on minimizing variability and imperfections in processes and products. The goal of Six Sigma is to achieve maximum output quality and minimize the occurrence of errors or defective products.

Six Sigma strives to achieve a level of 3.4 defective units per million opportunities, which corresponds to the statistical value of 6 sigma. This value is the basic principle of the methodology and explains its name.

Six Sigma uses a range of statistical tools and techniques to analyze and solve problems. It emphasizes measuring process performance, identifying the causes of problems and implementing effective solutions. This methodology was first introduced by Motorola in the 1980s and has since spread to many other industries and companies around the world.

Key benefits of using Six Sigma:

  • Six Sigma helps companies reduce costs and increase productivity.
  • Six Sigma improves the quality of project outputs by reducing inefficiencies and defects.
  • Six Sigma increases customer satisfaction and loyalty.
  • Certified Six Sigma professionals can make a significant contribution to increasing ROI.

Chart #1 suggests that Six Sigma is not limited to the manufacturing sector. It also finds its application in other sectors thanks to its many advantages. Today's competitive environment does not allow for mistakes. It is essential to constantly look for new ways to exceed customer expectations and provide them with maximum care. Six Sigma plays a significant role in this area, regardless of the specifics of the industry.
