Define lean manufacturing and waste reduction and give one short worked example.

# Lean Manufacturing and Waste Reduction ## Definitions **Lean Manufacturing** is a systematic approach to production that focuses on maximizing customer value while minimizing waste. It emphasizes continuous improvement and eliminating activities that don't add value to the final product. **Waste Reduction** refers to identifying and eliminating the "8 wastes" in production: - Defects - Overproduction - Waiting - Non-utilized talent - Transportation - Inventory - Motion - Extra processing ## Worked Example **Scenario:** A furniture factory assembles chairs on a production line. **Problem Identified:** - Workers walk 50 meters to a distant storage area to retrieve screws for each chair - This happens 100 times per day - Each trip takes 2 minutes (total: 200 minutes/day wasted) **Lean Solution Applied:** - Install small bins of screws directly at each workstation (5S methodology) - Implement a simple replenishment system **Results:** - Walking time eliminated: 200 minutes/day saved - At 100 chairs/day, this saves 2 minutes per chair - With 20 working days/month: 4,000 minutes (66.7 hours) saved monthly - Can now produce ~15-20 more chairs per month with same labor hours **Value Created:** Eliminated waste of motion and waiting, increased productivity without adding resources.
