Using principles and selected tools of lean six sigma to improve sustainability: A case study

Abstract

This article is focused on maintaining company's sustainability through application of principles and selected tools of Lean Six Sigma with the aim to improve the efficiency of the beer bottling line. Massive data collection and processing enabled to find core causes of micro-stoppages and reach for increasing the line efficiency which together with cost savings supported factory's sustainability. The article's benefits lie in application of LSS principles and methods to the micro-stoppages reduction and in the design of a modified sigma performance level based on DPMO where one opportunity is equal to one minute of a potential machine undesirable downtime.
