Using this type of maintenance, the occurrence of a failure in a component can cause failures in other components in the same equipment, which leads to low production availability. If there is an incentive for a contractor to deliver reliability, it naturally follows an incentive to prevent maintenance and to perform preventive maintenance, plan maintenance, schedule maintenance, and so forth. Difficult to control budgets As equipment failures can be unpredictable, labor and spare parts may not be readily available, so organizations may end up paying a premium for emergency parts shipping, travel time and out of hours support.
