Amazing how broadly applicable Little's Law is. (I suppose that's why it's a big-L law.)

We were just recently using it in business school to look at cycle times in assembly line output.

Very versatile -- It can also be applied to drug R&D organizations (one Dr. Jeffrey Low has proposed such an analysis)

The reason for this broad applicability is because it holds for any queueing system. The beauty of the law is that it holds for any distribution of arrival, occupancy, and latency. Just multiplying the averages gets the job done!
