Which philosophy focuses on reducing waste and defects and emphasizes continuous improvement to optimize production flow?

• A. Job simplification
• B. Just-in-time
• C. Facility master plan
• D. Influence

Answer: (B)

Reducing waste and defects while pursuing ongoing improvement to smooth the way work moves through the system is the hallmark of Just-in-Time as a Lean practice. Just-in-Time aims to produce only what is needed, when it is needed, and in the right quantity, so inventory, waiting, and overproduction are minimized. It treats quality as a built-in responsibility and relies on continuous improvement (kaizen) to identify and remove bottlenecks, improve processes, and create a steady, efficient production flow. A pull-driven approach signals when the next operation should start based on actual demand, keeping work moving smoothly rather than piling up in inventory. These elements together explain why this philosophy best fits the description. Job simplification concentrates on reducing task complexity, not the broader waste-reduction and flow-improvement focus. A facility master plan deals with long-term layout and capacity, not the ongoing improvement of daily flow. Influence isn’t a manufacturing philosophy.
