Final answer:
The key to increased throughput is shorter flow times.
Step-by-step explanation:
Little's Law suggests that the key to increased throughput is shorter flow times. Throughput refers to the rate at which a system can process inputs and produce outputs. By reducing the time it takes for a process to flow through a system, the overall throughput can be increased.
For example, in a manufacturing process, if the flow time from raw materials to finished product is shortened, more products can be produced in a given time period, leading to increased throughput.
On the other hand, while factors like fewer defects, eliminating waste, and increased inspection can contribute to improving productivity and efficiency, they may not have a direct impact on throughput as defined by Little's Law.
