Assessing the Impact of Lean Six Sigma Management on Organisational Productivity

Summary/Abstract: We conducted a comprehensive study to investigate the impact of Lean Six Sigma (LSS) management practices on organisational productivity across various industries. We employed a quantitative research approach, using structured questionnaires, to survey 44 professionals from diverse sectors, including manufacturing, IT/technology, healthcare, engineering, and finance. The survey assessed their perceptions of LSS implementation outcomes over a seven-day data collection period from June 6 to 13, 2025. Our results demonstrate that LSS significantly enhances organisational performance, with 88.7% of participants agreeing that LSS reduces organisational waste, 86.3% acknowledging its role in improving customer satisfaction, 81.8% recognising its contribution to organisational culture change, and 77.3% confirming its effectiveness in achieving competitive advantage. We also identified critical success factors, with Leadership and Facilitation rated as most essential (61.4%), followed by Process Improvement (59.1%) and Data Analytics (56.8%), while the primary implementation challenge was sustaining improvements over time (61.4% agreement). The study concludes that LSS provides substantial empirical evidence for enhancing organisational productivity through comprehensive waste reduction, improved customer satisfaction, cultural transformation, and strategic positioning across multiple industry sectors, emphasising the critical importance of leadership commitment, analytical capabilities, and sustained organisational support for successful implementation.
