How to Create a Preventive Maintenance Plan

Assessing Your Assets

Identifying Critical Assets

The first step is to identify the critical assets in your organisation. Critical assets are the backbone of your organisation’s operations. These are the assets that, if they were to fail, could lead to severe consequences, including safety hazards, production stoppages, or compromised patient care in healthcare settings. For example, in a manufacturing facility, critical assets might include specialised machinery that is vital for the production process. If a crucial machine breaks down, it can lead to costly production delays, leading to damaged sales and unhappy customers. For this reason, it’s essential that this machinery is prioritised in your preventive maintenance strategy.

Evaluating Asset Condition and Performance

To effectively maintain your assets, you need to know their current condition and how well they are performing. This assessment involves regular inspections, data collection, and analysis. Following on from the aforementioned manufacturing example, data collection for machines in manufacturing may include sensors on machines that can continuously monitor temperature, vibration, and other parameters. An increase in vibration levels may indicate a potential issue that needs attention. You may already be collecting extensive data on asset condition and performance; if you are not yet doing so, this may be a valuable way to boost the efficiency and reliability of your most important assets.

Prioritising Assets for Maintenance

Not all assets are equally critical, and resources are finite. Prioritisation ensures that the most critical assets receive the attention they deserve. This might involve a risk-based approach, considering factors like asset importance and the consequences of failure. For example, in the energy sector, assets in power plants might be prioritised based on their contribution to overall capacity and grid stability.

Setting Maintenance Goals

Determining Key Objectives

Define the key objectives of your preventive maintenance plan. What do you aim to achieve with this plan? It’s important to ensure that your maintenance goals align with your broader business objectives. For example, in manufacturing, your goal might be to reduce machine downtime by 20% over the next year, leading to increased production efficiency. On the other hand, in healthcare, your objective could be to ensure that all medical equipment meets regulatory compliance, thus improving patient safety and reducing legal risks.

Defining Performance Indicators

Establish key performance indicators (KPIs) to measure the success of your preventive maintenance plan. KPIs provide quantifiable metrics to track progress. The exact metrics you track will vary depending on the industry and the types of assets in your inventory; you might choose to track equipment uptime, number of equipment failures, or even customer satisfaction. Useful metrics include Overall Equipment Effectiveness (OEE), Mean Time Between Failures (MTBF), and Mean Time to Repair (MTTR).

Developing Maintenance Procedures

Documenting Asset-Specific Maintenance Requirements

Create detailed documentation of the maintenance requirements for each asset. This includes the specific tasks and procedures to be performed. Each asset may have unique maintenance requirements. In manufacturing, for example, a CNC machine may require regular lubrication, while a conveyor belt might need belt tension adjustments. The types of maintenance tasks can vary significantly within organisations – for example, an educational institution may require oil changes and tire maintenance on mini buses while also requiring lamp replacements for overhead projectors. For an effective preventive maintenance programme, documenting all these different needs is essential.

Outlining Frequency and Tasks

In preventive maintenance planning, outlining the frequency and tasks of maintenance activities is crucial to ensure that assets remain in optimal condition. The frequency and tasks should align with the asset’s specific needs and operational demands. For example, although a building’s elevators may be critical assets in the sense that they allow people to move around the building, it might not be realistic to carry out scheduled maintenance on them every month. Manufacturer guidelines often recommend maintenance at longer intervals, such as every three to six months.

Incorporating Manufacturer Recommendations

Following on from the previous point, manufacturers often provide detailed maintenance guidelines for their equipment. These recommendations are based on extensive testing and engineering expertise, making them essential for maintaining asset reliability and safety. They are especially useful when planning preventive maintenance tasks for assets that are new to the organisation and therefore there is not yet any historic data about their frequency of breakdown or needing repairs.

Scheduling Maintenance Activities

Creating a Maintenance Calendar

A well-structured maintenance calendar is a cornerstone of any effective preventive maintenance plan. It ensures that maintenance activities are carried out efficiently and at appropriate intervals. By appropriate, we mean finding a balance between maintenance and operational needs – the disruption caused by the preventive maintenance schedule should be minimised as much as possible. In retail, for example, routine HVAC maintenance is often scheduled during periods of low customer traffic to reduce disruptions and prevent customer dissatisfaction.

Assigning Responsibilities and Roles

Accountability is essential in preventive maintenance to ensure that tasks are completed efficiently and according to plan. As part of the preventive maintenance programme, you need to clearly define who is responsible for each maintenance task. Assign roles to maintenance technicians or teams to ensure accountability.

For example, in a transport and logistics organisation, responsibility for carrying out the planned maintenance may be spread among multiple people:

• Drivers: Conduct daily pre-trip inspections, checking tire pressure, brakes, and lights, and report any issues.
• In-House Mechanics: Perform weekly vehicle checks, including oil changes, fluid top-ups, and tire rotations.
• Specialised Technicians: Handle monthly and quarterly maintenance tasks, such as engine diagnostics, transmission inspections, and major component replacements.

Implementing a Tracking System

Selecting Equipment Maintenance Software

Implementing a robust equipment maintenance system is a pivotal aspect of an effective preventive maintenance plan. This system helps streamline maintenance activities, ensuring that assets are maintained efficiently. It’s important to choose suitable equipment maintenance software or tools that provide advanced reporting capabilities and real-time access to asset data as this can give a better indication of the success of your preventive maintenance strategy.

Tracking Maintenance History and Performance Metrics

Continuously monitoring and tracking maintenance history and performance metrics is crucial for making data-driven decisions and optimising preventive maintenance plans. With high quality equipment maintenance software, you can gain visibility over asset performance and maintenance tasks. FMIS asset management software allows you to generate detailed reports and analyse data which helps maintenance managers optimise operations.

Reviewing and Optimising

Conducting Regular Performance Reviews

Regular performance reviews are a critical component of maintaining an effective preventive maintenance plan. These reviews involve assessing the plan’s success in improving asset efficiency and reducing maintenance costs. The KPIs we mentioned earlier are relevant here, but it’s important also to identify trends in the data – look for patterns, such as which machines are most prone to breakdowns and where maintenance costs are highest. A cost-benefit analysis can help you assess whether the maintenance plan has reduced overall maintenance costs and improved asset reliability. Comparing data across different locations or using industry benchmarks is also valuable at this stage.

Making Adjustments and Improvements

Don’t be afraid to make adjustments and improvements to your preventive maintenance plan. After all, the readiness to make adjustments and improvements to the plan is an essential aspect of preventive maintenance. Adaptation to changing circumstances and technologies ensures the plan remains effective.

For example, this might include incorporating the latest sensor technologies and IoT capabilities into equipment to enhance predictive maintenance capabilities. It might include adjusting maintenance schedules based on equipment utilisation patterns and evolving production requirements. Moreover, it may be useful to establish feedback mechanisms where technicians can suggest improvements to maintenance procedures based on their real-world experiences.

Training and Communication

Providing Training to Maintenance Staff

Invest in the training of your maintenance technicians. Well-trained staff can execute maintenance tasks effectively and safely.

The new preventive maintenance plan may introduce new ways that staff receive work orders and new procedures for carrying them out, so it’s essential that everyone is trained in the new system. This allows the planned maintenance to go ahead smoothly and without a hitch. For example, maintenance technicians may need new equipment-specific training or safety training to boost effectiveness and workplace safety compliance.

Communicating the Plan to Stakeholders

Effective communication of the preventive maintenance plan to stakeholders is crucial for its success. This might include communicating:

• The Plan Overview: Present an overview of the preventive maintenance plan, its objectives, and its importance in ensuring effective operations.
• Roles and Responsibilities: Clarify the roles and responsibilities of employees, managers, and suppliers in supporting the maintenance plan.
• Communication Channels: Share the channels through which maintenance requests or issues should be reported.

Encouraging Feedback and Continuous Improvement

Creating a culture of continuous improvement through feedback is a key element of a successful preventive maintenance plan. This approach involves actively seeking input from individuals involved in the maintenance process and using their feedback to refine and enhance the plan over time. For example, you might establish multiple channels for feedback, including regular team meetings, suggestion boxes, and an electronic feedback system accessible to all maintenance staff. Recognising and rewarding valuable suggestions is also key to encouraging team members to share their ideas.
