The technical meaning of maintenance involves functional checks, servicing, repairing, or
replacing necessary devices, equipment, machinery, building infrastructure, and supporting
utilities in industrial, business, and residential installations.
Maintenance is essential in quality assurance and sometimes determines a company's long-term
success. Poorly maintained resources can cause instability and partially or entirely pause
production. Malfunctioning machines or complete breakdowns can become a costly process for
most companies.
Generally, there are six main maintenance strategies:
1. Reactive (run-to-failure)
2. Predetermined Maintenance.
3. Preventive Maintenance.
4. Corrective Maintenance.
5. Condition-based maintenance.
6. Predictive Maintenance.
