Productivity is calculated by dividing the output in a department (i.e. revenue, rooms occupied, covers) with the number of hours paid for. We separate between total productivity that takes output divided by the total hours and operational productivity when output is divided on productive hours only.
Example housekeeping: if 100 rooms are cleaned in 50 hours, the productivity is 2. [100(output) / 50(hours) = 2(productivity)]
