Benefits of Preventive Maintenance & Best Practices for Achieving Them

In the field of maintenance, the phrase, “If it ain’t broke, don’t fix it” definitely does NOT apply. Waiting until something breaks can result in catastrophic costs. But a little preventive maintenance goes a long way.

We’ll share all the benefits of preventive maintenance – and there are many – as well as best practices to ensure you make the most of it.

What is preventive maintenance?

Preventative maintenance is a category of maintenance tasks performed on machinery, facilities, or equipment at regular intervals (before they break down) to prevent them from malfunctioning, or otherwise requiring repair. 

Every piece of equipment (industrial, commercial, etc.) needs regular maintenance to stay in good working condition. By investing a little in these tasks, you can save a lot by avoiding unplanned downtime.

To get a more in-depth understanding of preventive maintenance, take a look at our comprehensive “What is preventive maintenance” post. 

Creating an effective PM plan

Preventive Maintenance may feel overwhelming, especially if you are switching from reactive to preventive maintenance. It can take time and resources to build an effective preventive maintenance program and plan with the necessary components (with triggers, schedules, reporting, and more).  But by remaining focused on the benefits, and making use of broadly applicable best practices, it is worth the investment.

Benefits of preventive maintenance

All organizations with a maintenance function can benefit from a preventive maintenance program. Here are the top benefits – financial and otherwise – of preventative maintenance. 

More efficient use of maintenance resources

Depending on the type and complexity of the equipment a company runs or the property it manages, maintenance resources can be one of the biggest financial sinkholes.

A preventive maintenance plan can help circumvent this problem by more efficiently using resources available.  

  • More frequent low-complexity tasks consume fewer resources, allowing a smaller team to manage a greater range of assets
  • Regular cleaning and tune-ups prevent issues that could lead to failure or reduced productivity
  • High-level technical experts don’t need to be hired for urgent or complex repairs as frequently

Furthermore, companies now have the added benefit of preventive maintenance software. These systems can provide regular maintenance checklists and help coordinate company-wide maintenance efforts, making it easier and more efficient than ever.

Early detection of malfunctioning symptoms

Thoroughly observing equipment disassembly and installation is a key preventive maintenance activity. It serves to reveal some obscure faults that would go undetected by a surface diagnosis.

  • Maintenance technicians discover potential malfunctions and resolve them before they occur
  • Machine disassembly reveals cavities and facets that are not visible from the outside
  • Examinations that occur during preventive maintenance reveal factors that can reduce machine productivity
  • Replacement of dirty or slightly faulty parts eliminates many serious defects
  • Installation of new functional software can implement auto diagnostics and fault-detection

Additionally, some computerized maintenance management software (CMMS) systems develop an IoT infrastructure that centralizes equipment performance reports. 

Reduced overall downtime

When downtime occurs, it severely impacts overall productivity. By reducing the likelihood of breakdowns, malfunctions, and lengthy repairs, preventive maintenance is the single most effectively way to avoid it.

  • Repairs can be done more quickly due to customized and well-researched preventive maintenance protocols
  • Improved equipment reliability prevents downtime altogether
  • Regularly maintained equipment eliminates production-line breakdowns and performance hampering

Fewer emergency work orders

Emergency maintenance is the most expensive and the most dreaded form of maintenance, especially for companies running high-value production equipment.

Regular preventive maintenance insulates an organization from these issues with the added benefit of avoiding overtime and diverting resources of maintenance staff.

  • Proactive maintenance scheduling allows for easier planning and procurement of parts and inventory needs
  • PM inspections identify and resolve potential failures that could otherwise lead to breakdowns requiring emergency repair
  • “Always on” systems such as elevators, ventilation, and HVAC have improved reliability
  • Static cosmetic fixtures have improved service life and quality 

A well-researched and well-executed PM program can render most emergency maintenance plans obsolete.

Prolonged asset life

Every piece of equipment eventually runs its course, requiring either repair or replacement. However, preventive maintenance can go a long way toward delaying the inevitable.

Here are some of the ways preventive maintenance prolongs asset health and overall life:

  • Helps detect and clear even the most minor faults
  • Allows technicians to judge whether a small adjustment or modification can be made to improve the running capacity of a machine
  • Enables machines to run cleaner, requiring fewer recalibrations
  • Allows calculation of asset depreciation, making better procurement decisions
  • Provides an entry point for effective computerized maintenance management systems to perform real-time monitoring

Smaller waste/scrap production

Poorly operating machines not only consume more power and material (grease, oil, etc.) but also slow down production, sometimes to a halt.

Preventive maintenance ensures no machine runs at less than optimal efficiency.  It also protects brand reputation by ensuring product quality and timeliness.

Here is how preventive maintenance results in waste reduction:

  • Ensures optimal operation and material consumption 
  • Provides regular opportunities for defect-detection
  • Saves on repair costs for more delicate parts, which could be a bigger cause of scrap
  • Allows engineers to develop better production parameters
  • Prevents late delivery which could result in wasted products

Some PM plans have built-in waste-reduction protocols that ingrain measures promoting waste-free production.

Preventive maintenance best practices

Preventive maintenance best practices have shifted as new technologies have emerged. Their applicability also varies based on a company’s size and scope. Here are seven tried and true best practices that can be applied across a broad range of organizations and maintenance programs.

Run a CMMS system

CMMS systems are at the center of maintenance operations in most modern companies worldwide and themselves provide numerous efficiencies and benefits.A virtual platform that centralizes all maintenance management activities, CMMS software automates much of the administration and documentation involved in preventive maintenance. 

Among other benefits of a CMMS system, using one to facilitate your preventive maintenance program can:

  • Automate preventive maintenance task scheduling
  • Attach maintenance checklists to maintenance tasks
  • Perform real-time inventory management
  • Report on KPIs and productivity metrics 
  • Facilitate documentation and workflows with customized fields

Continued training and development

Ongoing training is an essential component of any preventive maintenance program. It provides a venue to update your team on changes to your PM program and standard operating procedures (SOPs) that enable continuous improvement. 

A robust training and development program will result in:

  • Diversely talented maintenance personnel
  • More streamlined maintenance work
  • More efficient PM program implementation as training progresses
  • A steadily improving bottom line with no additional hires

Overall, maintenance staff training and development creates a stronger maintenance workforce, and a stronger maintenance program – both contributing to your bottom line.

Install performance monitoring sensors

Performance monitoring sensors can be installed on equipment to collect data which is then used to hone preventive maintenance plans. These IoT sensors can be set up and linked to a CMMS, allowing maintenance teams to see all the relevant data in one place for better management.

Installing these devices on machines has several benefits, including:

  • Automatic data collection for more precise and proactive maintenance
  • Remote monitoring for off-site machinery
  • Data-backed development of proactive maintenance programs
  • Reduced mean time to repair or completion for complicated maintenance tasks

Get expert engineers to develop PM plans

The maintenance managers and crew who work with your equipment regularly know those assets better than anyone. They should be the subject matter experts who help create and customize your PM plans.

Developing expert-backed PM plans has several benefits, including:

  • Highly detailed insights on regular tasks
  • More cost-effective preventive maintenance programs
  • Fewer parts and tools needed for preventive maintenance tasks
  • Low-redundancy plans that efficiently allocate PM resources
  • Greater customization compared to PM stock plans

Leverage historical data and machine learning

Sometimes looking to the future means we first have to look at our past. Developing a preventative maintenance plan based on maintenance histories will improve a company’s chances of eliminating resource waste. 

By tracking all maintenance tasks and finding patterns and ideal maintenance intervals you can determine which practices will help streamline your maintenance in the future. Analyzing long-term data offers several benefits to the PM framework. These include:

  • The ideal basis for a predictive maintenance strategy
  • More precise resource allocation for every job
  • Knowledge of maintenance parts, quality, and inventory needs 
  • Shorter troubleshooting and issue identification which reduces downtime

Prioritize tasks categorically

Most PM plans apply a one-size-fits-all approach to equipment maintenance. This means that some of the more valuable and complicated machinery get the same level of priority as other assets. Prioritizing and performing the most critical tasks first will make the biggest impact on your operations and maintenance goals.

Here are some of the advantages of categorically prioritized maintenance:

  • Increases the life of high-value machinery
  • Enables skill-based assignment of maintenance tasks, ensuring the right people are on the job
  • Prevents resource allocation to lower priority machinery
  • Saves time on individual service sessions
  • Allows for a smoother maintenance framework for newer companies

Final thoughts

While it may be tempting to rely on reactive maintenance, you will be better off investing the time to create and use a preventive maintenance plan. Not only will you improve the bottom line, but you will also reduce your overall downtime, increase the lifespan of assets, and decrease waste. 

And by sticking close to these best practices like utilizing a CMMS system, your program will begin to see results in no time.
