In a Manufacturing plant there are constraint machines in Department 25.  There are 30 machines and 15 operators.  Set up is done using help from available operators to minimize time spent on changeovers. The company is on a standard cost system and standard hours are set on direct labor man-hours.  Efficiency is earned compared to these labor standards. On this particular week the following rates of earned hours were achieved:

Monday     Tuesday     Wednesday     Thursday     Friday

 120             118              101                 125            99

If standards are set at an expectation of 7.5 hours per day per direct labor employee, and all employees were there for the full 8 hours each day, what is the efficiency for the department?
