Implementation of the Six Sigma methodology in increasing the capability of processes in the company of the furniture industry of the Slovak Republic

The aim of the article is to present the results of a case study focused on the implementation of the Six Sigma methodology in order to improve the quality and increase the efficiency of furniture production processes. Positive results of implementation after the implementation of corrective measures were achieved in the values of process capability coefficients, reduction of nonconformities and subsequent reduction of DPMO, increase of the values of the level of efficiency and sigma of the critical process.In the processing of the results, classical methods of research work were used such as analysis, synthesis, comparison, descriptive statistics, coefficients Cp a Cpk, DPMO, level of efficienty and sigma,and also graphic methods.
