Critical success factors of Lean Six Sigma deployment: a current review

The purpose of this paper is to review and gather the latest critical success factors (CSF) of Lean Six Sigma (LSS) deployment and implementation into a comprehensive list of factors.

The approach taken by authors in this study was to analyze the latest literature review starting 2010 onwards and focus on CSFs of LSS (not dedicated as Lean or Six Sigma) by excluding other improvement methodologies or initiatives, e.g. Lean, Six Sigma, TQM, TRIZ etc.

Five significant CSFs were identified (initially 97 CSFs listed from 13 papers) out of nine groups/headers listed in clustering analysis using Affinity Diagram tool and new headers mapping.

Most of the organisations were aware of the success story on LSS, but did not scrutinize or consider its CSFs. By knowing the outcome of this paper, it can help open eyes regarding readiness before implementing LSS.

At the end of this paper, the authors tried to cluster the CSFs similarities that could intentionally provide the guidelines and references to industries/companies for successful deployment and implementation of LSS in future endeavours.
