Gibson valves produces cast bronze valves on an assembly line, currently producing 2,000 valves during each 8-hour shift. if the production is increased to 2,400 valves for each 8-hour shift, the productivity will increase by
If the production of cast bronze valves increases to 2400 from 2000 in the same time period the productivity will increase by 2400/2000=1.2 x 100 = 120%. This is a significant increase in productivity and it would have to be determined if this increase was sustainable and the quality of the product did not suffer and that it didn't result in an onerous speed-up for the workers who produce the valves to ensure that safety was not compromised.
