SMED Implementation and Efficiency Improvements

The video tutorial introduces SMED (Single Minute Exchange of Die), a method for quick changeovers in production processes. It highlights the importance of reducing changeover times to prevent capacity loss and overproduction. A case study from the Lean Donut Shop demonstrates how using smaller baskets for pre-loading donuts significantly reduced changeover time, improving efficiency from 78% to 97% without additional costs. The tutorial concludes with an invitation to explore more resources at Lean Smarts Academy.
