How much actually gets done, not how busy it looked doing it.

means The actual rate at which a system produces finished output, measured over time.

from A straightforward 20th-century compound of 'through' and 'put' — literally what is put through a process. It took root in engineering and computing circles, describing how much data, material, or work actually passes through a pipe, machine, or system in a given time, as opposed to how fast any one piece moves or how busy things look.

bottleneck rule
System throughput equals its slowest stage, always
busy trap
Full utilization often lowers throughput via queueing
measured as
Units completed per unit time, not effort spent
