Run-to-Failure Maintenance- It is the earliest type of maintenance

where the machine was run until a faultcaused it to fail in service.

Costs are relatively high because ofunplanned downtime, damaged machinery,

and overtime expenditure.

It should be a very small part in a modernprogram, but there are some instanceswhere it does make sense. An example is aplant, which employs a great number ofsimilar machines that are not expensive toreplace or to repair.
