Quick changeover is a lean principle used to:

• A. Large batches and fewer changeovers
• B. Minimize machine downtime due to set-up
• C. Reduce the number of set-ups
• D. Standardize tooling

Answer: (B)

Quick changeover aims to minimize the downtime a machine experiences when switching from making one product to another. By speeding up the setup, you can run smaller batches and respond quickly to changes in demand without costly waiting time. That’s why the best choice is to minimize machine downtime due to set-up. Think of SMED (Single-Minute Exchange of Die) as turning as many setup steps as possible into things you do while the machine is running (external) and making the remaining steps as short as possible (internal). This runs in contrast to relying on large batches, which would require lengthy changeovers less often, and to simply reducing the number of set-ups without cutting the time each one takes. It’s also a supportive piece of tooling work, but the core objective is the speed and efficiency of the changeover itself.
