At what interval can an annual Maintenance Review (MR) be scheduled?

An annual Maintenance Review (MR) is typically scheduled to ensure that all maintenance operations are evaluated systematically and effectively throughout the year. The interval of 3 to 5 quarters is practical because it allows the supervisory personnel to conduct thorough assessments of maintenance performance and operations while still adhering to a regular review cycle that aligns with fiscal planning and operational requirements.

Scheduling the review within this interval ensures that there is sufficient time between reviews to implement any necessary changes or improvements that may arise from the previous review's findings. It also promotes continuity and consistency in maintenance practices, ensuring that issues can be addressed in a timely manner without overwhelming the review process. Thus, this interval is based on establishing a balance between thoroughness and efficiency, making it a standard approach in maintenance management practices.

In contrast, the other options do not align as closely with established practices or may not provide the same level of effectiveness in maintenance oversight. For example, allowing a review to take place in as few as two quarters could lead to rushed evaluations, while a wider range could lead to delays in addressing critical maintenance issues.
