What will a PM program failing to include frequency schedules likely lead to?

A preventive maintenance (PM) program that does not include frequency schedules often leads to uncertain maintenance practices and inconsistent outcomes. This is primarily because frequency schedules provide a clear guideline for how often maintenance tasks should be performed. Without these schedules, maintenance tasks can become irregular and haphazard, leading to variability in how well equipment or vehicles are maintained.

When maintenance is performed inconsistently, it can result in issues such as increased wear and tear, potential equipment failures, and unexpected downtimes. This uncertainty in maintenance practices can compromise reliability and performance. As a result, each vehicle or piece of equipment may experience different levels of maintenance, leading to inconsistent outcomes in terms of performance and reliability across the fleet.

In contrast, a well-structured PM program with defined frequency schedules promotes uniformity and predictability, ensuring that all units receive the necessary care at appropriate intervals. This standardization is essential for optimizing the operation of a fleet and minimizing risks associated with mechanical failures.
