Ans:
The production efficiency of workers and batch production are both measured using the efficiency formula. Efficiency is the work produced from a process, represented as a percentage, divided by the work input into the same operation. The following generic formula is used to determine efficiency -
100 times (Work output / Work input)
The efficiency formula would look something like this if you thought of work input and output in terms of "minutes". the ratio of total standard minutes generated to full minutes spent on the task.
