transportation waste

**Transportation waste** is the **unnecessary movement of materials or products between locations that does not transform the product** - every extra move adds time, handling cost, and defect risk without increasing customer value. **What Is Transportation waste?** - **Definition**: Any avoidable transfer of WIP, tools, or documents across excessive distance or handoffs. - **Typical Patterns**: Long cleanroom travel, cross-building shuttles, and repeated staging moves. - **Risk Exposure**: Additional handling increases contamination, damage, and tracking error probability. - **Cost Components**: Labor, automation time, queue delay, and transport-system maintenance. **Why Transportation waste Matters** - **Cycle-Time Penalty**: Transportation extends elapsed production time between value-added steps. - **Quality Risk**: More touches increase chance of mishandling and latent defects. - **Space and Layout Impact**: Poor flow layout creates avoidable travel loops and congestion. - **Energy and Labor Load**: Unnecessary movement consumes resources that add no customer value. - **Traceability Complexity**: Frequent transfers raise risk of misrouting and data mismatch. **How It Is Used in Practice** - **Flow Redesign**: Rearrange process sequence to reduce distance and handoff count. - **Point-of-Use Staging**: Position material and tools near consumption points to minimize travel. - **Transport KPI Control**: Track move count per unit and transportation dwell time by route. Transportation waste is **movement without value creation** - streamlined layout and handoff discipline reduce both lead time and quality exposure.
