Reschedule Preventive Maintenance

Learn how to prepare and verify a change to the planned execution date of a preventive intervention, including the rescheduling reason and checks on subsequent dates.

Rescheduling preventive maintenance (PM) is a common, yet critical, task in maintenance management. It allows for necessary adjustments to planned interventions due to operational demands, resource availability, or unforeseen circumstances, ensuring your maintenance plan remains practical and effective. Proper rescheduling minimizes disruption and optimizes asset performance.

Where it's available and step by step

Step by step in ManWinWin Desktop

1
Locate the preventive intervention to be moved and confirm its equipment, maintenance work and current planned date.
2
Identify the specific occurrence concerned and note its current date and the next planned occurrence for comparison after the change.
3
Confirm the date-change procedure for your version and establish whether it affects only the selected occurrence or also subsequent dates; if unclear, contact support@manwinwin.com before proceeding.
4
Using the confirmed procedure, enter the replacement planned execution date for the identified intervention.
5
Provide the rescheduling reason if required by your configuration, then check the new date and the scope of the change before saving.
6
Reopen the preventive schedule and compare the selected occurrence and subsequent dates with those noted earlier, confirming that only the intended changes have occurred.

Theory and technical background

Importance of Flexible Preventive Maintenance Schedules

While preventive maintenance aims for predictability, operational realities often necessitate schedule adjustments. A robust CMMS/EAM system allows for these changes without compromising the overall maintenance strategy. Flexibility in scheduling, supported by clear procedures, is vital for adapting to production changes, spare parts delays, or technician availability, ensuring that PM tasks are executed when most beneficial and least disruptive. This adaptability supports asset reliability and extends equipment life, aligning with ISO 55000 principles of asset management.

Rescheduling Reasons and Documentation

Every reschedule should ideally be accompanied by a documented reason. Common reasons include production priorities, resource unavailability, parts shortages, or even the identification of a more opportune time based on predictive insights. Documenting these reasons (as per EN 13306 definitions for 'postponement') is crucial for auditing, performance analysis, and continuous improvement. It helps identify recurring issues that might impact maintenance effectiveness and provides valuable data for future planning adjustments and resource allocation, ensuring accountability and traceability.

Impact on Maintenance KPIs and Future Planning

Rescheduling directly affects maintenance key performance indicators (KPIs). While necessary, frequent reschedules can skew metrics like PM compliance, availability, and Mean Time Between Failures (MTBF) if not properly managed. Understanding whether a reschedule affects only one instance or a whole series of future dates is paramount. Always verify the scope of the change to maintain the integrity of your long-term maintenance plan. Careful rescheduling ensures that asset health and operational efficiency are maintained, and future planning is not negatively impacted.

Best practices

Always document the specific reason for any PM reschedule.
Verify the scope of the reschedule: single instance or recurring series.
Communicate schedule changes promptly to relevant stakeholders.
Review the impact of reschedules on your PM compliance rates regularly.

Frequently asked questions

Why is it important to document the reason for a PM reschedule?

Documenting reasons provides valuable data for analysis, helping identify recurring issues, improve future planning, and maintain compliance records. It ensures transparency and accountability for schedule changes.

What happens if a PM is rescheduled too often?

Frequent rescheduling can negatively impact PM compliance, asset reliability, and equipment availability. It may also indicate issues with initial planning, resource allocation, or production demands.

Should I reschedule a PM if an asset is running perfectly?

Preventive maintenance is critical even for well-running assets to prevent future failures. Only reschedule if there's a strong operational or resource-based reason, always assessing the potential risks.
