13 Preventive Maintenance Best Practices

Preventive maintenance (PM) is no longer an option—it's a necessary operational requirement. Industries, ranging from manufacturing to healthcare, are adopting proactive asset management.

This approach helps reduce downtime, improve safety, and extend the life of their equipment. At the heart of any successful PM program are the best practices that support its sustainability and effectiveness.

This article offers a clear guide to the best practices for preventive maintenance.

Understanding the Foundation of Preventive Maintenance

Before we delve into best practices, it’s essential to understand what preventive maintenance entails. PM is regular equipment servicing done on a set schedule. This plan prevents waiting for equipment to fail.  It can include tasks such as:

• Inspection
• Lubrication
• Adjustments
• Cleaning
• Part replacements
• System testing

Preventive maintenance helps find and fix potential issues early. This cuts down on emergency repairs and saves money by reducing downtime. Implementing a preventive maintenance strategy is more than setting reminders. It involves strategy, accuracy, and ongoing tweaks.

Best Practices for Preventive Maintenance

1. Start with a Thorough Asset Inventory

A key step in preventive maintenance is creating a detailed inventory of all assets. Make a complete list of all equipment, machinery, tools, and infrastructure that help your operations.

Best Practice Tips:

• Make a list of:
• Asset name
• Location
• Serial/model number
• Date of purchase
• Warranty info
• Manufacturer recommendations
• Maintenance history
• Use barcodes or QR codes to make tracking easier.
• Classify assets based on criticality (mission-critical vs. non-essential).

A full asset inventory sets the stage for your entire maintenance program. It helps prioritize efforts, assign resources, and build custom PM schedules.

2. Develop Maintenance Schedules Based on Data

The timing of maintenance tasks is crucial. Scheduling maintenance too often can waste resources and cause wear. But if maintenance is too rare, it raises the risk of failure. The optimal schedule balances these extremes and relies on data.

Best Practice Tips:

• Start with the manufacturer's recommendations. Then, adjust them using real performance data. If you don’t have the manufacturer-recommended maintenance checklists, you can leverage tools like Zoidii’s AI Checklist Generator.
• Consider how much the asset is used, like run hours, cycles, and mileage. Also, think about the environmental conditions.
• Start with time-based schedules and gradually shift toward usage-based or condition-based triggers.

Using data for schedules helps companies avoid guesswork. This leads to better and more efficient maintenance efforts.

3. Use Standardized Procedures and Checklists

Consistency is key in preventive maintenance. Having technicians "wing it" leads to variability and missed steps. Create and use Standard Operating Procedures (SOPs) and checklists for each asset type.

Best Practice Tips:

• Outline:
• Task Instructions: List steps clearly for each PM task.
• Tools Needed: Write down all tools required for each task.
• Safety Procedures: Outline safety measures to follow.
• Estimated Time: Provide an estimate for how long each task will take.
• Keep all formats together in one spot. A Computerized Maintenance Management System (CMMS) is a great choice for this.
• Update procedures based on feedback, asset upgrades, or changes in safety regulations.

SOPs help keep work quality consistent. They lower errors and simplify training for new staff. Here is Zoidii’s guide on creating and implementing Standard Operating Procedures (SOPs).

4. Implement a Computerized Maintenance Management System (CMMS)

Modern preventive maintenance cannot scale without digital support. A CMMS is a software platform that helps schedule, assign, track, and document all maintenance activities.

Best Practice Tips:

• Use the CMMS to automate work orders and reminders.
• Track parts inventory, technician performance, and asset health metrics.
• Pick a CMMS that has mobile access, is easy for technicians to use and has a scheduler.

Organizations that utilize CMMS platforms tend to experience improved maintenance compliance, faster response times, and reduced administrative overhead.

5. Prioritize Based on Asset Criticality

Not all assets need the same level of preventive attention. Allocate resources based on the importance of an asset to operations, safety, or compliance.

Best Practice Tips:

• To rank assets, perform a Failure Modes and Effects Analysis (FMEA) or Risk Priority Number (RPN) analysis.
• Focus on preventive maintenance for assets that could lead to safety issues, production halts, or regulatory breaches if they fail.
• Adjust PM frequency based on historical data and real-world performance.

Criticality-based prioritization ensures your PM efforts provide the highest return on investment.

6. Ensure Proper Training and Certification

Even the most well-designed preventive maintenance program can fail without skilled technicians. Human error, inconsistent execution, or a lack of knowledge can undo all planning.

Best Practice Tips:

• Provide initial and recurring training in PM procedures, software tools, and safety practices.
• Encourage certification through industry-recognized bodies (e.g., Certified Maintenance & Reliability Professional - CMRP).
• Develop mentorship programs that pair experienced techs with new hires.

Trained staff demonstrate greater efficiency and accuracy in their work. They can also spot problems before they grow.

7. Document Everything—and Use That Data

Record-keeping is a core part of preventive maintenance. Log and store every completed task, any found anomalies, or replaced parts for future reference.

Best Practice Tips:

• Utilize CMMS to document maintenance history, including photos, technician notes, and timestamps.
• Conduct regular reviews of maintenance logs to identify trends or recurring issues.
• Use documentation to support warranty claims, audits, and insurance requirements.

Proper documentation not only ensures regulatory compliance but also feeds the feedback loop necessary for continuous improvement.

8. Leverage Key Performance Indicators (KPIs)

To evaluate the success of your PM program, you need measurable goals. KPIs help you monitor performance and identify areas for improvement.

Best Practice Tips:

• Track KPIs such as Mean Time Between Failures (MTBF), Mean Time to Repair (MTTR), PM Compliance Rate, Maintenance Cost per Unit Output, and Downtime Hours.
• Set benchmarks and targets for improvement.
• Review KPIs on a monthly or quarterly basis in cross-functional meetings.

KPIs change maintenance from a cost center into a value creator. They link your preventive maintenance program to business results.

9. Establish a Continuous Improvement Culture

Preventive maintenance isn’t a “set it and forget it” strategy. To stay effective, your PM program must evolve as your business grows and your equipment ages.

Best Practice Tips:

• Conduct periodic audits of your PM program and procedures.
• Encourage technicians to report inefficiencies or suggest improvements.
• Stay updated with industry trends, new tools, and technology.

When continuous improvement is part of the culture, preventive maintenance becomes a dynamic system that adapts and improves over time.

10. Use Mobile Technology for On-the-Go Maintenance

Gone are the days of clipboards and paper forms. Mobile maintenance software applications enable technicians to access tasks, manuals, and history on their phones or tablets.

Best Practice Tips:

• Equip technicians with mobile devices or tablets.
• Ensure your CMMS or maintenance platform is compatible with mobile devices.
• Use mobile tools to capture photos, voice notes, and real-time issue reports.

Mobile-enabled CMMS makes communication easier. It reduces delays in reporting and resolving issues. Also, it boosts accuracy in the field.  Read more about how you can empower your team with a mobile-enabled CMMS.

11. Optimize Spare Parts Management

Preventive maintenance usually means replacing parts before they fail. But if the needed parts are unavailable, it can cause delays or incomplete work.

Best Practice Tips:

• Maintain optimal inventory levels for critical spares.
• Utilize your CMMS to track parts usage and automate reorder requests.
• Store parts in a secure manner and label them in a way that allows for quick access.

Proper parts management is the backbone of a well-executed PM schedule. Here are 8 tips to help optimize spare parts management.

12. Schedule Around Operations to Minimize Disruption

While preventive maintenance is important, it shouldn’t bring operations to a halt. Effective scheduling ensures that maintenance teams perform their tasks without negatively impacting productivity.

Best Practice Tips:

• Coordinate with operations and production teams before scheduling maintenance.
• Plan tasks during planned downtime, holidays, or night shifts if possible.
• Bundle multiple maintenance tasks to reduce the frequency of interventions. This can be accomplished by leveraging a CMMS that includes Nested PMs.

Collaboration across departments helps align PMs with broader business objectives. A well-functioning work order scheduler within the CMMS will also make scheduling preventive maintenance much easier.

13. Engage All Stakeholders in the Process

Preventive maintenance is not just the responsibility of the maintenance team. Operators, safety personnel, and even procurement departments play a role.

Best Practice Tips:

• Train operators in basic maintenance checks and how to report anomalies.
• Involve procurement in sourcing reliable spare parts and equipment.
• Hold cross-functional meetings to align priorities and resolve bottlenecks.

The more departments invest in preventive maintenance, the more successful and cohesive the program is.
