Impact of Lean Six Sigma on companies' performance during the COVID-19 pandemic

Abstract

This study aims to assess how Lean Six Sigma (LSS) affected companies' performance during the Coronavirus pandemic. A total of 390 LSS specialists who live in the USA and work for a US company filled out a questionnaire. The research tool was validated, and reliability was assessed. Statistical analysis methods, such as multiple regression and correlation, were employed to test the hypothesis. The results show that LSS projects have a substantial influence on a company's overall performance and all of it is sub-dimensions: financial, operational, and innovative performance. However, the effects were minor, and the connections were strained. These findings may appear odd, but only when taken out of context, in that this study was conducted on LSS projects implemented during the COVID-19 pandemic, which includes a plethora of internal and external variables that may influence a company's performance.
