Run to Failure. This is a maintenance strategy or replacement policy, which is sometimes also called “Fit and Forget”. An intentional strategy whereby no maintenance tasks are performed on an asset. The only "planned maintenance" on the asset is corrective maintenance after the asset has suffered a failure. Sometimes referred to as fit and forget maintenance, run to failure is perhaps the most cost-effective of the maintenance strategies, and one that is fairly widely. Preventive Maintenance 2. Corrective Maintenance 3. Reactive Maintenance 4. Run-to-Failure Maintenance 5. Predictive Maintenance 6.

Short Life Asset - Sometimes short life assets. Disposable Assets - Assets with disposable parts. These include equipment items that have failure probability curves like those shown in b and e.
Low equipment criticality Equipment that has a low criticality could also be considered for run-to-failure maintenance. Run to failure maintenance lightbulb on the factory roof, for example, will not cause a threat to life, nor have a significant impact on company profits.
This lightbulb could, therefore, be subject to a run-to-failure maintenance regime.
You may have other equipment types that do not have safety or profit implications should they fail. These too, could be candidates for run-to-failure maintenance. Or maybe you were the guy headed out to pick up the spare parts for that machine run to failure maintenance had a "run to failure" tag attached to it - more added cost - lol!
Reactive Maintenance activities are those that make little or no attempt to prevent run to failure maintenance. Equipment is allowed to fail and after it fails, repairs or replacements are made.
Run-to-failure and corrective maintenance fall into this category.
It may well incorporate what is termed as a preventive maintenance program and may use proactive technologies, but the still see failures at startup. Run-to-Failure Maintenance activities are activities that allow an asset run to failure maintenance run to catastrophic failure.
Inventory costs — The maintenance team needs to hold spare parts in inventory, to accommodate for intermittent failures.

If the asset is not working, then maintenance is required. Shutting it down for monthly maintenance would stop production and create the same disruption as if you had just let it break down which might happen 1 time a year.
In this case, it makes sense to simply repair it when it breaks. Run to fail maintenance requires an understanding of how a machine might break and what the consequences of breakdown are.
