For accounting purposes, maintenance costs are treated as a specific item of expenditure, and are generally divided into the sub-categories of material costs, labour costs, outsourcing costs and so on.

Since maintenance encompasses such a wide range of complex activities, from daily routine maintenance through equipment inspection and repair to corrective maintenance, good results cannot be achieved if people try to do it on their own.

Each factory should determine its own machines’ priorities, depending on their effect on the factory’s overall production (volume and quality) and factors such as how much damage the machines would sustain if they broke down.

Effective maintenance is progressed by initiating activities designed to reduce failures and gradually building up a preventive maintenance system.
