Full origin of maintenance →Frequently asked questions
What is the difference between maintenance and repair?
Maintenance is planned work done to stop things going wrong — servicing, cleaning, replacing parts on schedule. Repair happens after something has already failed. Good maintenance is what reduces the amount of repair needed.
What is the difference between preventive and corrective maintenance?
Preventive maintenance is carried out at set intervals regardless of condition, to head off failures. Corrective maintenance is triggered by a fault that has been found, and restores the equipment to working order.
How do you spell maintenance?
It is m-a-i-n-t-e-n-a-n-c-e. The common error is "maintainance", carried over from the verb "maintain" — but the noun drops the "i" in the second syllable.
