Which statement describes the impact of maintenance scheduling?

• A. Scheduling maintenance reduces unscheduled downtime.
• B. Scheduling maintenance increases unscheduled downtime.
• C. Scheduling maintenance has no effect on downtime.
• D. Scheduling maintenance is optional.

Answer: (A)

Proactive maintenance scheduling targets preventing unexpected problems by having routine checks and replacements done before wear leads to a failure. When maintenance is planned, technicians address potential issues—lubricating parts, replacing worn components, recalibrating systems—so equipment stays in good condition and surprises are minimized. This approach reduces the chance of unplanned outages, which is why scheduling maintenance lowers unscheduled downtime. If maintenance isn’t planned, or is treated as optional, the risk of sudden failures and unplanned downtime typically rises, and the idea that scheduling would have no effect or that it increases downtime doesn’t fit how preventive care works.
