What are the four classifications of Maintenance according to the Product Maintenance process?

The four classifications of maintenance according to the Product Maintenance process are typically recognized as Scheduled, Demand, Emergency, and Unplanned. Scheduled maintenance refers to proactive maintenance activities that are planned in advance, often based on time or usage intervals, ensuring equipment remains in optimal condition. Demand maintenance occurs in response to specific requests or needs due to equipment failure or performance issues, focusing on immediate repairs.

Emergency maintenance is executed in critical situations where equipment failure could lead to significant disruptions or safety concerns, requiring immediate attention. Unplanned maintenance refers to any unforeseen maintenance tasks that arise unexpectedly, often resulting from equipment breakdowns.
