Which lean practice is specifically concerned with reducing downtime during transitions between products?

• A. Quick changeover
• B. Just-in-time
• C. 5S
• D. Poka-yoke

Answer: (A)

The fundamental idea here is cutting the time a production line spends not producing while it switches from one product to another. Quick changeover focuses on that transition period, aiming to shrink setup and changeover times so the line can start producing the next product sooner. It uses techniques like SMED to separate tasks that can be done while the machine is running from tasks that must be done when the machine is stopped, converts as many tasks as possible to external setup, and streamlines tools and steps so changeovers are faster and more reliable. This reduction in downtime directly enables smaller batch sizes, faster response to demand, and greater flexibility on the line. Just-in-time is about delivering the right parts at the right time to minimize inventory and improve flow, not specifically about reducing downtime during product transitions. 5S focuses on workplace organization and cleanliness to support efficiency, not the changeover timing itself. Poka-yoke deals with preventing human or process errors, not changing how long it takes to switch between products.
