A measurement of the actual output relative to the optimal output expected (design capacity). -- A measure of process output divided by input that helps us determine the effectiveness of the process. -- The measure of process output divided by more than one input, where those inputs must be expressed in a common unit of measure, like dollars. -- A measurement of the actual output relative to the standard output expected (effective capacity). -- A measure of process output divided by only one input of the many possible inputs required to make the desired output. 1.
