Operations Management Question: Utilization, efficiency, and productivity:

The operations manager creates an 8 hour shift with a 30 minute lunch and two 10 minute breaks, one in the morning and one in the afternoon. With personal bathroom and other breaks, such as stretching, the manager feels the workers actually put in 7 hours of productive time in the shift.

The manager uses 3 workers to switch the connectors. After each shift each worker on average produces 58 sets of 20 connectors.

Calculate the utilization, efficiency, and productivity.

Will the owner be satisfied?
