ANALYSIS OF EFFICIENCY OF LEAN MANUFACTURING AND SIX SIGMA IN A PRODUCTION ENTERPRISE

The aim of the paper is to identify, on the basis of selected examples, the effectiveness of Lean Manufacturing (LM) and Six Sigma (SS) techniques in a large-production enterprise characterized by low-volume production, a wide product range, stabilized manufacturing technology and a so-called "brownfield" site. Many scholars have attempted to answer which approach, LM or SS, is more effective in a production enterprise. The authors of the paper aim to answer this question on the basis of a detailed analysis of efficiency of implementation of both techniques. The amount of savings generated from undertaken projects and increase of profitability of the analysed production system have served as performance measurements.
