And that during the period from 2016 to 2021 and in order to achieve the objectives of the study, the researchers used the descriptive analytical approach by designing a survey form and distributing it to the research sample, which included (7) banks out of the study population amounting to (46) banks, as well as the researchers used many statistical methods Others such as (standard deviation, arithmetic means, T test, F test, and multiple linear regression model for data analysis and validation of the study hypotheses. The study concluded a set of results, the most important of which are: The increase in the value of the variable SIXSIGMA by one unit leads to an increase in the value of the variable rate of return on equity by an amount 0.83 and an increase in the value of the SIXSIGMA variable by one unit leads to an increase in the value of the variable rate of return on total assets by 0.78, as the study recommended the need to apply the SIX SIGMA approach in commercial banks in order to reduce defects and errors in order to reach perfection
