In today’s competitive and complex business environment, achieving business excellence requires a combination of effective methodologies and strong leadership to drive and sustain organizational transformation. Lean Six Sigma (LSS), a proven methodology for improving operational efficiency, relies on effective leadership for successful implementation and lasting impact. This study examines how the integration of Lean, Six Sigma, and Total Quality Management (TQM) shapes leadership strategies that enhance organizational agility, resilience, and responsiveness to market dynamics. It highlights the crucial role of leadership in fostering collaboration, optimizing resource utilization, and cultivating a culture of continuous improvement. The study introduces the Structured Lean Leadership Framework as a strategic tool to develop the leadership capabilities essential for LSS success, addressing challenges such as weak leadership commitment, resistance to change, and communication barriers. Through the application of the DMAIC framework, Key Performance Indicators (KPIs), and Voice of Customer (VOC) analysis, the research aligns LSS with business objectives, customer needs, and sustainability goals. Additionally, it explores how combining LSS with Agile methodologies can improve operational efficiency, governance, and innovation, helping organizations better navigate future challenges. This research offers valuable insights for executives, practitioners, and researchers, supporting leadership development, data-driven decision-making, and long-term value creation. Future studies should focus on validating the Structured Lean Leadership Framework, exploring Agile-LSS integration in regulated industries, and examining the impact of Industry 4.0 technologies on LSS and leadership.
