> Little's law I guess that's the OP's point that you can't escape from talking about queues and which you sort of validated by bringing up Little's law. Queues are literally everywhere around us in the physical world. It needs to be understood at a basic level -- Little's law is good enough and only requires primary school math. If execs aren't able to understand such a ubiquitous and simple concept then I don't know what to say. Average flow rate is indeed useful but please explain that along with a queue and show whoever needs to know how queues can grow unboundedly if output rate is consistently less than input rate. And if needed explain further the upstream consequences of unbounded queue growth.
