Video Summary
What if Lean, Six Sigma, and Agile could work together as one? In this episode of The Big Picture, Professor Vijaya Sunder discusses his study on a new approach to process improvement that integrates these methods into a unified, synergistic model. Referred to as ‘Lean Additives,’ the framework is designed to address the limitations of using each method in isolation. The model was implemented and refined over three years at a global bank. The study found that this integrated system led to measurable improvements in both efficiency and effectiveness.
