Six Sigma is a management approach and methodology aimed at improving the quality of production and processes. Its goal is to minimize errors and variability in processes and achieve maximum reliability and efficiency.
The Six Sigma methodology focuses on measuring and analyzing data that allows identifying problems in processes and subsequently proposing and implementing improvements. Six Sigma is based on statistical analysis, which makes it possible to determine exactly what influence individual factors have on the process and what their causes are.
The Six Sigma concept was developed by Motorola in the 1980s. Later it was also applied in other companies such as General Electric and Ford Motor Company. Today, Six Sigma is widely used in various industries and industry segments.
