The 21st century has presented the maintenance world with the opportunity to advance their maintenance strategy with new technology. Predictive maintenance utilizes sensor data and connected software systems to predict when a failure is likely to occur, thereby reducing unplanned downtime and breakdowns, increasing uptime and maximizing use.
Asset sensors combined with data historians, EAM systems, and advanced maintenance software, have enabled maintenance organizations to optimize their maintenance processes by implementing a predictive maintenance program and move away from reactive or preventive maintenance and their associated challenges. To review the challenges with reactive and preventive maintenance, read our Reactive vs Preventive vs Predictive Maintenance blog post.
The Goal of Predictive Maintenance
The goal of predictive maintenance is first and foremost to predict when an asset failure might occur, and in turn, prevent the failure.
Monitoring for future failure allows maintenance to be conducted at the exact time it is needed, rather than too early, while the part still has life, or too late, when the part has already failed.
This means the frequency of maintenance can be as low as possible, while still preventing unplanned downtime and breakdowns (Reactive Maintenance) and without incurring the costs associated with time interval maintenance (Preventive Maintenance).
Predictive Maintenance Challenges
Predictive maintenance does not come without its challenges, however. It requires an intricate system of asset sensors and software systems, as well as advanced changes to maintenance and data management processes.
1. Investment
Switching to predictive maintenance often involves significant upfront costs. The installation of sensors, purchase of software, and necessary hardware can be expensive. Additionally, the time and resources required to integrate these new technologies into existing systems can strain budgets and operations in the short term. Businesses should also factor in ongoing maintenance and support costs for these tools.
2. Execution and Integrations
The technological transition to predictive maintenance requires seamless integration with existing systems such as Enterprise Resource Planning (ERP) and Computerized Maintenance Management Systems (CMMS). Without proper integration, predictive insights may not align with daily operations, leading to inefficiencies. Aligning these systems and managing the transition smoothly can be a complex and resource-intensive process, requiring both time and skilled personnel.
3. Data Challenges
One of the key aspects of predictive maintenance is data accuracy and availability. Poor data quality, whether from outdated or malfunctioning sensors, or insufficient data management practices, can lead to faulty predictions and unreliable insights. Ensuring that data is consistently collected, stored, and analyzed in real-time is crucial. Furthermore, large datasets require robust infrastructure for storage and processing, adding to the technical complexity.
4. Adoption Challenges
Introducing predictive maintenance can face resistance from employees who are accustomed to traditional maintenance practices. Overcoming this resistance involves investing in comprehensive training programs to help employees understand the benefits and functionality of predictive maintenance tools. Additionally, addressing any concerns around job security and reassuring the workforce that these technologies aim to support their roles rather than replace them can facilitate smoother adoption.
5. Privacy and Security
With the collection of vast amounts of data comes the increased risk of security and confidentiality issues. Predictive maintenance systems must comply with relevant regulations regarding data privacy, and it’s essential to implement strong cybersecurity measures to prevent data breaches. Protecting sensitive information from unauthorized access while still leveraging data-driven insights is a critical challenge that must be addressed to avoid potential liabilities.
6. Ongoing Improvement and Scalability
Once predictive maintenance is implemented, it’s essential to continuously refine and improve the system. Regular monitoring of performance is necessary to ensure predictive models remain accurate and relevant. As technology evolves, predictive maintenance systems must be scalable, allowing for easy updates and expansions as new assets and data sources are integrated into the system. Ongoing employee training and upskilling also play a crucial role in adapting to these changes.

How Does an Organization Successfully Become Predictive?
Maintenance organizations cannot simply just become a predictive organization. There are several factors they need to review before they can dream of having a successful predictive maintenance program.
Predictive maintenance is the way of the future. Every day, more technology is being released, pushing maintenance organizations towards this strategy. The benefits of a successful predictive maintenance program mean improved efficiency, and decreased maintenance costs. But how does an organization overcome the challenges and successfully implement a predictive maintenance process?
Predictive maintenance may seem like an unattainable nirvana for maintenance teams. A concept that is nice to dream about, but impossible to actually achieve.
Machines telling you when a problem is occurring, so you can fix it before it breaks down? How is this actually possible? A successful predictive maintenance program is only possible when an organization prepares for it properly.
It is important for organizations to consider several operational areas when they decide to switch to a predictive maintenance program.
Operational Considerations for a Predictive Maintenance Program
1. Understand Your Asset Criticality
Before your organization can implement a predictive maintenance strategy, you must first understand your asset criticality.
- Which assets are your most important for production?
- Which assets break down the most frequently?
- Which assets have the most costly repairs?
- Which assets cost you the most in lost production time?
Knowing the answers to these questions helps your organization to focus their maintenance processes on your most critical assets and assist in making critical decisions related to your predictive maintenance strategy. Additionally, rules can be aligned with operational readiness to meet different business goals.
2. Understand Your Infrastructure Requirements
Predictive maintenance is dependent on new age technology. Asset sensors will need to be installed on ‘old-clunky machines’ in order for asset information to be collected. Additional software may be required for data to be collected and effectively managed. These implementations need to take place before a predictive maintenance program can begin.
3. Determine How You Will Use Time Savings
Predictive maintenance inherently saves maintenance teams’ time and makes them more efficient. Your organization will need to determine how you want to utilize these time savings. You may choose to complete more work orders in a day. Alternatively, you may decide that preventive maintenance is still appropriate in certain scenarios and use these tasks to fill the additional time. Whatever the scenario, you will need a plan for the additional time savings.
4. Figure Out How To Increase User Adoption
When implementing any new software, system or process, user adoption should always be a number one concern. Simply put, without user buy-in, the new system will fail. Predictive maintenance disrupts all your current maintenance processes. It is important to ensure that plans are put in place for process implementation and user training.
5. Decide How To Handle Data Management
When an organization begins tracking their assets, the volume of data can quickly become overwhelming. Systems, processes, and people need to be put in place to ensure the right data is being tracked to enable the organization to accurately predict failures and malfunctions.
The Role of AI in Improving Predictive Maintenance
Artificial Intelligence (AI) helps to enhance predictive maintenance strategies. By analyzing vast amounts of real-time data generated from asset sensors and connected systems, AI helps optimize maintenance schedules, improve asset reliability, and reduce operational disruptions. Here's how AI is transforming predictive maintenance:
Advanced Data Analysis
AI algorithms can sift through enormous volumes of data collected from sensors and historical records to identify patterns, trends, and anomalies that may not be immediately apparent to human operators. Machine learning models can continuously learn and improve, providing more accurate predictions about when equipment is likely to fail. This predictive capability allows maintenance teams to act proactively, reducing the chances of unplanned downtime.
Predicting Failures with Greater Accuracy
Traditional methods of predicting equipment failures often rely on time-based schedules or operator intuition. AI takes these predictions to the next level by using data-driven insights. It can forecast potential failures based on factors such as wear and tear, environmental conditions, and historical performance, ensuring that maintenance is performed at the optimal time. As a result, AI-based predictive maintenance improves accuracy, minimizes unnecessary downtime, and maximizes asset lifespan.
Optimizing Maintenance Strategies
AI can help optimize maintenance strategies by analyzing the operational efficiency of assets over time. With machine learning, AI can determine which maintenance strategies (e.g., predictive vs. preventive) work best for specific assets under various operating conditions. This leads to more targeted and efficient maintenance efforts, allowing teams to focus on high-priority areas and avoid wasting time and resources on low-impact repairs.
Automated Decision-Making
AI systems can automate many decision-making processes involved in predictive maintenance, such as when to schedule maintenance or which parts require attention. By doing so, AI helps reduce human error, streamline workflows, and enhance the speed of response to potential issues. Automated decisions allow maintenance teams to operate more efficiently, responding to predicted failures before they escalate into costly problems.
Continuous Improvement with Feedback Loops
AI systems can continuously evolve and refine their predictions based on feedback from actual maintenance outcomes. This feedback loop allows predictive maintenance strategies to become more precise over time. As new data is fed into the system, AI adapts its models, improving its accuracy and predictive capabilities. This ongoing learning process ensures that the system remains reliable and effective, even as operational conditions and assets evolve.
Improving Resource Allocation
AI's predictive capabilities extend beyond just equipment health. By analyzing patterns in maintenance needs, AI can help allocate resources more effectively. This includes optimizing labor schedules, inventory management, and repair parts procurement. With smarter resource allocation, organizations can reduce costs and ensure that teams are ready and well-equipped for upcoming maintenance tasks, thereby improving operational efficiency.
AI serves as a cornerstone for predictive maintenance, offering more precise, efficient, and proactive solutions. By leveraging AI, asset-intensive industries can significantly enhance their maintenance strategies—driving cost savings, reducing downtime, and extending the life of critical equipment.
Is There an Easy Way To Start Transitioning To a Predictive Maintenance Strategy?
Predictive maintenance strategies can be complicated, especially if your organization was not previously capturing asset data. A pilot program is a more simplistic way to transition your team from a solely reactive or preventive maintenance program to a predictive program.
A pilot program allows organizations to test that sensors, systems, and team members are all on the same page and that your strategy is working as imagined. If problems arise, processes can be adjusted to promote success on larger scale implementations.
Pilot programs also provide organizations with a cost-effective way to test the ROI of their proposed predictive maintenance strategy. Organizations can set up the predictive process on one or two critical assets as a base point to prove the value of the process change. Part of becoming a predictive maintenance organization involves convincing management of its benefit. For this to be possible, you need a sound ROI. Contact us to talk to an expert today.
Transition Your Maintenance From Preventative To Predictive
When predictive maintenance is working effectively as a maintenance strategy, maintenance is only performed on machines when completely necessary, meaning maintenance is only performed on machines when a failure is likely to occur. This strategy gives maintenance organizations with several cost savings areas including:
- Reducing asset downtime
- Minimize the cost of spare parts and supplies
- Maximize utilization of maintenance staff.
These cost saving areas cannot be realized without proper planning prior to transitioning your maintenance strategy. Maintenance organizations need to be sure they are approaching their predictive maintenance strategy not from a 50,000-foot level, but from the ground, with all the details in clear view.
