How is planned maintenance defined in equipment management?

Planned maintenance in equipment management is defined as conducting maintenance and testing according to a regular schedule. This approach focuses on proactive measures to ensure that equipment operates efficiently and reliably over time. By adhering to a predetermined maintenance schedule, organizations can anticipate and address potential issues before they lead to equipment failures. This not only prolongs the life of the equipment but also minimizes unexpected downtime, which can be costly.

In contrast, the other statements reflect reactive approaches or unscheduled methods, which do not align with the principles of planned maintenance. For example, performing maintenance only when necessary or based on unscheduled needs may lead to increased risks of equipment failure, as problems may go unnoticed until they become severe. Similarly, executing maintenance only after an equipment failure occurs means that the organization has missed the opportunity to prevent downtime and maintain operational efficiency. Therefore, the essence of planned maintenance lies in its systematic and scheduled nature, which enhances reliability and performance in equipment management.
