In terms of office space for example, we reviewed the operation and changed the frequency of vacuum cleaning from everyday to twice a week, wiping of desks and chairs to twice a week, and wiping of office equipments such as telephone to once a week. Consequently, we negotiated with the cleaning service company and succeeded to lower the cleaning consignment cost.
In order to determine the appropriate frequency, we set the examination period and sufficiently considered if there would be no problems by reducing the cleaning frequency.
By these activities, we managed to reduce the monthly cost by 25%, and on an annual basis, we succeeded to reduce 3.8 million yen.
