Corrective is suitable for non safety-critical assets that have low costs compared to their maintenance costs. Here, a break down has little impact. Preventive is best used with safety-critical or expensive long life time assets, like infrastructure or industrial goods. Predictive maintenance can suit both strategies though it makes more sense in preventive scenarios. It minimizes unused wear out reserve and unused life time of an asset. Also, it enables optimization of maintenance via efficient planning and execution.
