Final answer:
Principle 6 is part of the Lean methodology focusing on visualizing and limiting work in progress, decreasing batch sizes, and controlling queue lengths to enhance production efficiency. The option (B) is correct.
Step-by-step explanation:
The principle that emphasizes visualizing and limiting work in progress, reducing batch sizes, and managing queue lengths is Principle 6. This principle is part of the Lean methodology which aims to streamline production and eliminate waste, thus ensuring efficiency and effectiveness in the work process.
By visualizing work in progress (WIP), teams can limit multitasking and reduce context switching, ensuring that tasks are completed before new ones are started. Reducing batch sizes facilitates quicker feedback and reduces the time products spend in the manufacturing cycle, which enhances flexibility and adaptability. Managing queue lengths helps to avoid bottlenecks in the production process, which is crucial for maintaining a smooth flow of work and timely deliveries. Therefore, option (B) is correct.
