Certified Maintenance & Reliability Professional (CMRP) Practice Exam

What percentage of maintenance work should ideally be proactive?

1. Less than 50%

2. 50% to 75%

3. 85% or more

4. Always 100%

The correct answer is: 85% or more

The ideal percentage of proactive maintenance work should be 85% or more because proactive maintenance focuses on preventing equipment failures before they occur, which is essential for maximizing reliability and minimizing downtime. This approach helps organizations shift from reactive to a proactive maintenance strategy, thus reducing overall maintenance costs, improving asset performance, and enhancing safety. An 85% or higher proactive maintenance strategy allows for systematic planning and execution of maintenance activities, such as predictive maintenance, condition-based maintenance, and scheduled overhauls, which contribute to better resource allocation and more effective maintenance management. This level of proactive maintenance aligns with best practices in asset management and reliability engineering, ultimately leading to improved operational efficiency and prolonged asset life. Less than 50% or even 50% to 75% of proactive maintenance falls below the optimal threshold for significant benefits. Relying on too high a percentage of reactive maintenance can lead to increased unplanned downtimes, higher repair costs, and a lack of reliability in operations. Always aiming for 100% proactive maintenance is impractical and overlooks the necessity for some reactive measures in response to unforeseen issues or breakdowns.
