Digital twin concept.  Industrial manufacturing automation technology. A man with digital twin icons in his hand.

Industrial organizations today operate increasingly complex assets. Modern production facilities, energy infrastructure, and manufacturing systems generate enormous volumes of operational data. Yet even with this data, maintenance teams often struggle to fully understand how assets behave over time and under different operating conditions.This is where Digital Twin technology is beginning to reshape maintenance and asset management.A digital twin is a virtual representation of a physical asset or system, continuously updated with real-time data from sensors, operational systems, and historical records. By combining physical asset data with advanced analytics and simulation models, digital twins allow organizations to monitor performance, analyze behavior, and predict future outcomes.In essence, a digital twin creates a living digital model of an asset—allowing engineers and maintenance teams to observe, analyze, and optimize equipment performance without directly interacting with the physical asset itself.<h3>Understanding Digital Twins </h3>The concept of the digital twin originated in product lifecycle management and engineering simulation. Over time, advances in connectivity, sensors, and computing power have enabled digital twins to become dynamic, real-time representations of operating equipment.A typical digital twin integrates several key elements:<ul><li>Sensor data capturing real-time asset condition and operational parameters</li><li>Engineering models representing the design and performance characteristics of the asset</li><li>Historical maintenance and reliability data</li><li>Advanced analytics and simulation capabilities</li></ul>By combining these elements, the digital twin mirrors the behavior of the physical asset.This capability allows organizations to test scenarios, analyze failure mechanisms, and evaluate maintenance strategies within the virtual environment before implementing changes in the real world.According to research from the McKinsey Global Institute, digital technologies that combine operational data and advanced analytics can significantly improve asset productivity and reliability (Manyika et al., 2011).<figure id="figure-osd3zku5uommgcaqhb"><img id="osd3zku5uommgcaqhb" src="https://cdn.durable.co/getty/93P0IvP4r2k65GHKLkbSPkHYAJtKPx1bBIbm6WTfsNy3lLXcpFREl4B1qti5BI5n.jpeg" alt="Digital twins technology concept.

By analyzing real-time operational data alongside historical performance trends, digital twins can identify early indicators of equipment degradation.This allows maintenance teams to anticipate potential failures and schedule interventions before equipment breakdown occurs.Failure analysis and troubleshooting Digital twins also provide valuable insight when investigating equipment problems. Engineers can analyze operating conditions, review historical data, and simulate potential failure scenarios within the digital environment.This capability often accelerates root cause analysis and improves the quality of reliability investigations.Maintenance strategy optimization Maintenance strategies such as preventive maintenance intervals or inspection schedules can be evaluated using the digital twin model. By simulating different operating conditions, organizations can determine the most effective maintenance approach without exposing the physical asset to risk.<h3>Improving Asset Lifecycle Management </h3>Beyond day-to-day maintenance decisions, digital twins can also support long-term asset lifecycle management.Because digital twins integrate engineering design data with operational performance information, they provide a comprehensive view of how assets behave over their entire lifecycle.This insight allows organizations to evaluate questions such as:<ul><li>How operating conditions influence equipment degradation</li><li>Which maintenance strategies deliver the greatest reliability improvements</li><li>When asset refurbishment or replacement may be required</li></ul>Standards such as ISO 55000 emphasize the importance of managing assets throughout their lifecycle to maximize value and minimize risk (ISO, 2014). Digital twin technology supports this objective by providing a continuous flow of performance data that informs strategic asset management decisions.<figure id="figure-8ue108cbjltmmgce7jy"><img id="8ue108cbjltmmgce7jy" src="https://cdn.durable.co/getty/18UFCq2p3TIn7zAaBtBCap8yUyUj4Ryy5pmWZ3R0PPFiXrzlkpyEGycM93DaqiQq.jpeg" alt="A labyrinth maze with a glowing yellow path on a blue background suggesting a concept of problem solving. 3D Rendering" title="A labyrinth maze with a glowing yellow path on a blue background suggesting a concept of problem solving. 3D Rendering" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9; object-position: center center;" data-corners="default" data-aspect="16:9" data-caption="" data-positionx="undefined" data-positiony="undefined" data-fullwidth="false" data-mce-src="https://cdn.durable.co/getty/18UFCq2p3TIn7zAaBtBCap8yUyUj4Ryy5pmWZ3R0PPFiXrzlkpyEGycM93DaqiQq.jpeg" data-mce-style="aspect-ratio: 16/9; object-position: center center;"></figure><h3>Challenges and Implementation Considerations </h3>Despite their potential, digital twins are still an emerging technology in many industries. Implementing digital twin solutions requires several important foundations.Reliable data infrastructure Digital twins depend heavily on accurate and consistent data from sensors, monitoring systems, and maintenance records. Poor data quality can significantly limit the effectiveness of digital twin models.Integration of multiple systems A successful digital twin typically integrates information from several sources, including operational technology systems, maintenance management systems, and engineering databases.Achieving this level of integration can require significant technical coordination.Organizational capabilities Finally, organizations must develop the analytical skills required to interpret digital twin insights and translate them into practical maintenance actions.Technology alone cannot improve reliability. The greatest value comes when digital tools are combined with strong engineering expertise and effective maintenance processes.As Davenport and Harris observe, organizations that successfully integrate analytics into operational decision-making consistently outperform those that rely primarily on intuition (Davenport &amp; Harris, 2017).<h3>The Future of Digital Twins in Maintenance </h3>As sensor networks expand and data analytics technologies continue to advance, digital twins are likely to play an increasingly important role in maintenance and reliability management.In the future, digital twins may allow maintenance teams to monitor entire asset systems in real time, simulate operational scenarios, and optimize maintenance strategies continuously.When integrated with artificial intelligence and predictive analytics, digital twins could ultimately enable fully data-driven maintenance ecosystems, where maintenance decisions are supported by continuous analysis of asset behavior.For organizations seeking to improve reliability, reduce downtime, and optimize asset performance, digital twin technology represents a powerful step toward the next generation of maintenance management.<figure id="figure-kiz0yqdrhsmmgcharn"><img id="kiz0yqdrhsmmgcharn" src="https://cdn.durable.co/getty/0k4NW9QUDCcH65lKTZ4aduEFF9X8O8Nk5X0nyiKKZY9VrgnK7LTCXHeeXKXUrW0O.jpeg" alt="Colorful Speech Bubbles On Blue Background" title="Colorful Speech Bubbles On Blue Background" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9; object-position: center center;" data-corners="default" data-aspect="16:9" data-caption="" data-positionx="undefined" data-positiony="undefined" data-fullwidth="false" data-mce-src="https://cdn.durable.co/getty/0k4NW9QUDCcH65lKTZ4aduEFF9X8O8Nk5X0nyiKKZY9VrgnK7LTCXHeeXKXUrW0O.jpeg" data-mce-style="aspect-ratio: 16/9; object-position: center center;"></figure><h3>💬 Discussion </h3>How familiar is your organization with digital twin technology?Consider the following questions:<ul><li>Has your organization explored or implemented digital twin solutions for critical assets?</li><li>What types of equipment or systems would benefit most from digital twin modeling in your operations?</li><li>What challenges have you encountered when integrating operational data with digital models?</li><li>Do you see digital twins becoming a standard tool for maintenance and reliability teams in the future?</li></ul>Share your experience in the comments.What opportunities—or barriers—do you see when applying digital twin technology in maintenance environments?<figure id="figure-ixwu9k8kbhmmgcif96"><img id="ixwu9k8kbhmmgcif96" src="https://cdn.durable.co/getty/19JuMVzItBzR72pgCwvEot6I8VoQItCqcGkz3Q30RITpUWawXw2FhqTAXgUmNh9G.jpeg" alt="Coming Soon" title="Coming Soon" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9; object-position: center center;" data-corners="default" data-aspect="16:9" data-caption="" data-positionx="undefined" data-positiony="undefined" data-fullwidth="false" data-mce-src="https://cdn.durable.co/getty/19JuMVzItBzR72pgCwvEot6I8VoQItCqcGkz3Q30RITpUWawXw2FhqTAXgUmNh9G.jpeg" data-mce-style="aspect-ratio: 16/9; object-position: center center;"></figure>This article is part of a series exploring how data, digital technologies, and advanced analytics are reshaping modern maintenance and reliability management.Next in the series: The Role of AI in Maintenance Management, examining how artificial intelligence is enabling predictive insights and smarter maintenance decisions.<h3>References </h3>Davenport, T.

Digital Twins in Maintenance

Fingerprint Hologram on Futuristic Digital Background

Maintenance management is undergoing a significant transformation. Traditionally, maintenance teams relied heavily on scheduled inspections, manual data collection, and technician experience to identify developing equipment issues. While these approaches remain valuable, they are increasingly being complemented—and in many cases replaced—by smart sensors and connected monitoring systems.The integration of smart sensors into industrial equipment is enabling a new maintenance paradigm often referred to as Smart Maintenance. By continuously monitoring equipment health and performance, sensors provide real-time insights that allow organizations to detect problems earlier, intervene more effectively, and improve overall asset reliability.In simple terms, smart sensors allow equipment to communicate its condition, enabling maintenance teams to act before failures occur.<h3>What Are Smart Sensors? </h3>Smart sensors are advanced sensing devices capable of measuring physical conditions such as vibration, temperature, pressure, flow, or acoustic emissions. Unlike traditional sensors, smart sensors typically include built-in processing capabilities and connectivity, allowing them to transmit data directly to centralized monitoring systems.These devices form the foundation of the Industrial Internet of Things (IIoT), where networks of connected sensors continuously collect operational data from across the asset base.Typical applications include:<ul><li>Vibration sensors monitoring rotating equipment such as pumps and motors</li><li>Temperature sensors detecting overheating in mechanical and electrical systems</li><li>Pressure sensors identifying abnormal process conditions</li><li>Acoustic sensors detecting leaks or early bearing faults</li><li>Lubrication sensors monitoring oil condition and contamination</li></ul>When integrated with modern analytics platforms, these sensors provide continuous visibility into equipment health.<figure id="figure-k1iih2xh6mmgbcx53"><img id="k1iih2xh6mmgbcx53" src="https://cdn.durable.co/getty/1dfHDhNsnGBe5NRcda9RprbLTYcy2OZsyP7mnsHpLUa476IBWkOq8C4zjSLFnalR.jpeg" alt="Quality Assurance and Certification Compliance Concept.

While these methods can detect many faults, they may miss rapidly developing failures that occur between inspections.Smart sensors address this limitation by enabling continuous monitoring.Instead of relying on periodic snapshots of equipment condition, organizations gain access to real-time data streams that reveal how equipment behavior evolves over time.For example, a gradual increase in vibration amplitude may indicate developing bearing wear. If detected early, maintenance teams can plan repairs during scheduled downtime rather than responding to an unexpected failure.Continuous monitoring significantly improves the ability to detect early-stage faults, allowing organizations to intervene at the optimal moment.According to reliability research, predictive maintenance enabled by advanced monitoring technologies can reduce equipment breakdowns by up to 70% while lowering maintenance costs by 25–30% (Mobley, 2002).<h3>Enabling Data-Driven Maintenance Decisions </h3>Smart sensors generate large volumes of operational data. When analyzed effectively, this data provides valuable insights into asset performance.Modern monitoring systems can automatically analyze sensor data to identify abnormal conditions, detect anomalies, and alert maintenance teams when intervention may be required.This capability enables organizations to move toward condition-based and predictive maintenance strategies, where maintenance actions are triggered by actual equipment condition rather than fixed schedules.For maintenance leaders, this represents a significant shift from reactive response to proactive decision-making.As sensor networks expand across industrial facilities, maintenance teams gain a more comprehensive understanding of how assets behave under different operating conditions.This deeper insight allows organizations to:<ul><li>Identify developing equipment faults earlier</li><li>Optimize maintenance scheduling</li><li>Reduce unnecessary preventive maintenance tasks</li><li>Improve equipment reliability and availability </li></ul><figure id="figure-w2henbh8cmmgbg1hb"><img id="w2henbh8cmmgbg1hb" src="https://cdn.durable.co/getty/25vDoBJpUotRPChTVPVSZGxbMTubMjNcJw6Hd7QAchaYDksZr4UIly26IkeRAmJT.jpeg" alt="Finding Solutions Among Questions.

Sensor data must be integrated with existing maintenance systems such as CMMS or EAM platforms to ensure that insights translate into actionable maintenance tasks.Data management is another critical issue. As sensor networks grow, organizations must ensure that data is properly stored, analyzed, and interpreted.Finally, maintenance teams must develop the skills required to interpret sensor data and respond appropriately. Technology provides information, but human expertise remains essential for diagnosing problems and determining the correct intervention strategy.Standards such as ISO 14224 emphasize the importance of structured reliability data and effective maintenance processes to support data-driven decision-making (ISO, 2016).<h3>The Role of Smart Sensors in the Future of Maintenance </h3>The adoption of smart sensors is accelerating rapidly across asset-intensive industries. As sensor costs decline and connectivity improves, organizations are increasingly deploying monitoring technologies across broader portions of their asset base.When combined with advanced analytics, artificial intelligence, and digital twin technologies, smart sensors provide the foundation for fully connected maintenance ecosystems.In these environments, equipment health can be monitored continuously, predictive models can forecast potential failures, and maintenance actions can be scheduled proactively.As Davenport and Harris note, organizations that effectively leverage data and analytics gain significant competitive advantages through improved operational decision-making (Davenport &amp; Harris, 2017).For maintenance leaders, the integration of smart sensors represents a major step toward achieving truly intelligent maintenance management.<figure id="figure-3tv18x7fqrmmgbielw"><img id="3tv18x7fqrmmgbielw" src="https://cdn.durable.co/getty/0k4NW9QUDCcH65lKTZ4aduEFF9X8O8Nk5X0nyiKKZY9VrgnK7LTCXHeeXKXUrW0O.jpeg" alt="Colorful Speech Bubbles On Blue Background" title="Colorful Speech Bubbles On Blue Background" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9; object-position: center center;" data-corners="default" data-aspect="16:9" data-caption="" data-positionx="undefined" data-positiony="undefined" data-fullwidth="false" data-mce-src="https://cdn.durable.co/getty/0k4NW9QUDCcH65lKTZ4aduEFF9X8O8Nk5X0nyiKKZY9VrgnK7LTCXHeeXKXUrW0O.jpeg" data-mce-style="aspect-ratio: 16/9; object-position: center center;"></figure><h3>💬 Discussion </h3>How is your organization using smart sensors to monitor equipment health?Consider the following questions:<ul><li>Has your organization implemented sensor-based condition monitoring systems?</li><li>Which types of sensors (vibration, temperature, acoustic, lubrication) have delivered the greatest value?</li><li>What challenges have you encountered when integrating sensor data with maintenance systems?</li><li>How has continuous monitoring influenced your maintenance decision-making?</li></ul>Share your experience in the comments.What has been the most valuable insight—or the biggest challenge—when implementing smart sensor technologies in maintenance?<figure id="figure-m52vak6c2bmmgbjrn5"><img id="m52vak6c2bmmgbjrn5" src="https://cdn.durable.co/getty/19JuMVzItBzR72pgCwvEot6I8VoQItCqcGkz3Q30RITpUWawXw2FhqTAXgUmNh9G.jpeg" alt="Coming Soon" title="Coming Soon" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9; object-position: center center;" data-corners="default" data-aspect="16:9" data-caption="" data-positionx="undefined" data-positiony="undefined" data-fullwidth="false" data-mce-src="https://cdn.durable.co/getty/19JuMVzItBzR72pgCwvEot6I8VoQItCqcGkz3Q30RITpUWawXw2FhqTAXgUmNh9G.jpeg" data-mce-style="aspect-ratio: 16/9; object-position: center center;"></figure>This article is part of a series exploring how data, digital technologies, and advanced analytics are reshaping modern maintenance and reliability management.Next in the series: Digital Twins in Maintenance, examining how virtual representations of physical assets are enabling deeper insight into equipment performance and lifecycle management.<h3>References </h3>Davenport, T.

Smart Maintenance: Integrating Smart Sensors

Industrial organizations today generate more operational data than ever before. Sensors monitor equipment continuously, maintenance systems record thousands of work orders, and operational systems capture detailed process parameters. Yet despite this abundance of information, many maintenance decisions are still made using limited insight.This is where Big Data is transforming maintenance management.Big Data refers to the ability to collect, store, and analyze vast quantities of structured and unstructured information in order to identify patterns, trends, and relationships that would otherwise remain hidden. In the context of maintenance, it enables organizations to move beyond reactive responses and toward data-driven reliability strategies.For asset-intensive industries, the implications are significant. When maintenance teams can analyze large datasets from across their operations, they gain the ability to anticipate failures, optimize maintenance schedules, and improve asset performance.<figure id="figure-1slb3th48dmmeynwz7"><img id="1slb3th48dmmeynwz7" src="https://cdn.durable.co/getty/29zWtuWUeJnYelXfQLN0iTuMpmORQUP36U7lZI83U7sKsSy9Hfmvu7FfSJaEqTyC.jpeg" alt="Big Data technology innovation background" title="Big Data technology innovation background" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9; object-position: center center;" data-corners="default" data-aspect="16:9" data-caption="" data-positionx="undefined" data-positiony="undefined" data-fullwidth="false" data-mce-src="https://cdn.durable.co/getty/29zWtuWUeJnYelXfQLN0iTuMpmORQUP36U7lZI83U7sKsSy9Hfmvu7FfSJaEqTyC.jpeg" data-mce-style="aspect-ratio: 16/9; object-position: center center;"></figure><h3>What Big Data Means for Maintenance </h3>Big Data in maintenance is not simply about collecting more information. The real value lies in connecting multiple sources of operational data to generate deeper insight into equipment performance.Typical data sources include:<ul><li>Condition monitoring systems (vibration, temperature, pressure, etc.)</li><li>Maintenance records from CMMS or EAM systems</li><li>Process data from operational control systems</li><li>Inspection reports and reliability studies</li><li>Operator observations and event logs</li></ul>When these datasets are analyzed collectively, organizations can uncover relationships that are difficult to detect when information is examined in isolation.For example, a reliability analysis might reveal that pump failures correlate with specific process conditions, operating loads, or environmental factors. With sufficient data, organizations can identify these patterns and address the underlying causes rather than simply responding to repeated failures.According to Davenport and Harris, organizations that effectively analyze large datasets can gain significant operational advantages by improving decision-making (Davenport &amp; Harris, 2017).<h3>From Data to Insight </h3>One of the key strengths of Big Data analytics is its ability to process extremely large datasets rapidly. Traditional analysis methods often rely on small sample sizes or historical averages, which may not capture the complexity of modern industrial operations.Big Data platforms, however, can evaluate thousands—or even millions—of operational data points simultaneously.This capability allows organizations to detect subtle changes in equipment behavior. Small deviations in vibration patterns, temperature trends, or process parameters may indicate the early stages of equipment degradation.By identifying these patterns early, maintenance teams can intervene before failures occur.This approach moves maintenance strategy from reactive repair toward predictive reliability.Research from the McKinsey Global Institute suggests that data-driven maintenance programs can reduce machine downtime by up to 50% while increasing equipment life by 20–40% (McKinsey &amp; Company, 2018).<figure id="figure-h180rgojyahmmeysty0"><img id="h180rgojyahmmeysty0" src="https://cdn.durable.co/getty/9ASCIosDMX1jDpQQh6TOKeZ49CZi9wp6sLjfKAzkrO4Myg3rHsxO1tAH0JiTBUIp.jpeg" alt="Quality Control and Certification Assurance Concept.

Maintenance data alone rarely tells the full story of equipment performance.When maintenance data is combined with operational data, organizations gain a far clearer understanding of asset behavior.For example:<ul><li>Process data may reveal that equipment failures occur during specific operating conditions.</li><li>Production data may show that high utilization accelerates wear in certain components.</li><li>Environmental data may explain corrosion, contamination, or degradation trends.</li><li>Integrating these datasets enables reliability engineers to develop more accurate failure models and more effective maintenance strategies.</li></ul>Standards such as ISO 14224 emphasize the importance of collecting structured reliability and maintenance data to support this type of analysis (ISO, 2016).<h3>Enabling Predictive Maintenance </h3>Big Data analytics is also a key enabler of predictive maintenance.Advanced algorithms and machine learning models can analyze historical equipment data to identify patterns associated with failure events. Once these patterns are understood, predictive models can monitor real-time data and alert maintenance teams when similar conditions begin to emerge.Instead of reacting to breakdowns, maintenance teams receive early warnings that allow them to plan maintenance interventions in advance.This approach delivers several benefits:<ul><li>Reduced unplanned downtime</li><li>Improved maintenance planning and scheduling</li><li>Lower maintenance costs</li><li>Extended asset life</li><li>Improved operational safety</li></ul>However, predictive maintenance depends heavily on the quality and consistency of underlying data. Poorly structured data, incomplete failure records, or inconsistent asset hierarchies can significantly reduce the effectiveness of analytics models.<figure id="figure-x1pjlw8c7mmeyyguh"><img id="x1pjlw8c7mmeyyguh" src="https://cdn.durable.co/getty/10qFDqzmLMloHOVQ2Ep1uAUCl8BcsBSgdbWV7kH65urVHBMh1dCThnpAYISaZNGm.jpeg" alt="Untangling tangled threads as concept of problem solution.

Industrial organizations often collect large quantities of data, but much of it remains fragmented across different systems.The second challenge is data quality. If maintenance records are incomplete or inconsistent, analytical models may produce misleading conclusions.Finally, organizations must develop the skills and expertise required to interpret data and translate insights into practical maintenance decisions.Technology alone does not deliver results. Successful organizations combine data analytics with strong reliability engineering practices and disciplined maintenance processes.As noted by Manyika and colleagues, the true value of Big Data lies not simply in collecting information but in the ability to extract meaningful insight that improves operational performance (Manyika et al., 2011).<h3>💬 Discussion </h3>How effectively is your organization using operational data to support maintenance decisions?Consider these questions:<ul><li>Does your organization integrate maintenance data with operational or process data?</li><li>What challenges have you encountered when trying to analyze large datasets from industrial systems?</li><li>Have data analytics or predictive tools helped your organization identify equipment failures earlier?</li><li>What barriers prevent maintenance teams from fully using the data available to them?</li></ul>Share your experience in the comments.<ul><li>What has been the biggest opportunity—or challenge—when using data analytics to improve maintenance performance?</li></ul><figure id="figure-bdx8vah70cmmez2lqi"><img id="bdx8vah70cmmez2lqi" src="https://cdn.durable.co/getty/254t98uMqXcbZLDwYqWpTV8VxCxNdvtySMUsmZWrJnRHYVTcJGtG21vXFWhKjjk6.jpeg" alt="Ripped paper with 'coming soon' text" title="Ripped paper with 'coming soon' text" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9; object-position: center center;" data-corners="default" data-aspect="16:9" data-caption="" data-positionx="undefined" data-positiony="undefined" data-fullwidth="false" data-mce-src="https://cdn.durable.co/getty/254t98uMqXcbZLDwYqWpTV8VxCxNdvtySMUsmZWrJnRHYVTcJGtG21vXFWhKjjk6.jpeg" data-mce-style="aspect-ratio: 16/9; object-position: center center;"></figure>This article is part of a series exploring how data, digital technologies, and advanced analytics are reshaping modern maintenance and reliability management.Next in the series: Smart Maintenance: Integrating Smart Sensors, exploring how connected sensors and Industrial Internet of Things technologies are transforming equipment monitoring and reliability.<h3>References </h3>Davenport, T.

The Impact of Big Data on Maintenance

For decades, many maintenance strategies have been built around the calendar. Equipment is serviced every three months, six months, or annually—regardless of its actual condition. While this time-based preventive approach represented a major improvement over reactive maintenance, it is known that approximately 88% of equipment failures occur randomly (Moubray, 2002). So, why stick with calndar-based maintenance routines?Today, organizations operating complex assets are shifting toward Condition-Based Maintenance (CBM)—a proactive strategy that monitors equipment health in real time and triggers maintenance only when indicators show that intervention is necessary.The logic is simple: maintain assets based on their condition, not on arbitrary intervals.This shift is transforming maintenance management across asset-intensive industries, improving reliability while reducing unnecessary maintenance activity and cost.<figure id="figure-9wcdkavnikmmex7vqb"><img id="9wcdkavnikmmex7vqb" src="https://cdn.durable.co/getty/308PXIhpctv5uxsvhEQEfnOGzO3X0zIwkGh2wwuS6At3Uim83t4YtuYTIePtQ2z2.jpeg" alt="Cogwheel gear and calendar, Technical support, Repair, Setting symbol, optimization and workflow concept" title="Cogwheel gear and calendar, Technical support, Repair, Setting symbol, optimization and workflow concept" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9; object-position: center center;" data-corners="default" data-aspect="16:9" data-caption="" data-positionx="undefined" data-positiony="undefined" data-fullwidth="false" data-mce-src="https://cdn.durable.co/getty/308PXIhpctv5uxsvhEQEfnOGzO3X0zIwkGh2wwuS6At3Uim83t4YtuYTIePtQ2z2.jpeg" data-mce-style="aspect-ratio: 16/9; object-position: center center;"></figure><h3>Understanding Condition-Based Maintenance </h3>Condition-Based Maintenance involves monitoring the actual health and performance of equipment to determine when maintenance should be performed. Rather than relying on fixed schedules, CBM uses condition indicators—such as vibration levels, temperature trends, lubricant analysis, or acoustic signals—to identify early signs of deterioration.Maintenance actions are then scheduled only when the data indicates that equipment performance is beginning to decline.This approach delivers two major advantages:<ol><li>Failures can be detected before they occur, allowing intervention at the optimal time.</li><li>Unnecessary maintenance is reduced, avoiding premature component replacement and wasted labor. </li></ol>Research suggests that predictive and condition-based maintenance programs can reduce maintenance costs by up to 30% and decrease breakdowns by as much as 70% when implemented effectively (Mobley, 2002).<h3>How CBM Works in Practice </h3>Condition-Based Maintenance relies on monitoring technologies that track asset health over time. Some of the most widely used techniques include:Vibration analysis for rotating equipment such as pumps, motors, and compressors<ul><li>Thermography to detect abnormal heat patterns<ul><li>Used in both electrical systems and mechanical components</li></ul></li><li>Oil and lubricant analysis<ul><li>Used to identify contamination, wear particles, and degradation</li></ul></li><li>Ultrasound monitoring<ul><li>Used to identify leak detection and early bearing failure identification</li></ul></li><li>Process parameter monitoring<ul><li>Uses operational data such as pressure, flow, or temperature</li></ul></li></ul>These techniques allow maintenance teams to detect early warning signs of developing faults. For example, a slight increase in vibration amplitude may indicate bearing wear long before catastrophic failure occurs.By identifying the issue early, maintenance teams can plan repairs during scheduled downtime rather than responding to an unexpected breakdown.<figure id="figure-0gq4aaohummey1bdp"><img id="0gq4aaohummey1bdp" src="https://cdn.durable.co/getty/5N9umpbB0cbBZPfG4M8vyzP6tFSvWhBqHedNiJmlnvPJ5Qpl9VWESwi0SO3nLoiW.jpeg" alt="Laptop and tools in maintenance at garage service station." title="Laptop and tools in maintenance at garage service station." class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9; object-position: center center;" data-corners="default" data-aspect="16:9" data-caption="" data-positionx="undefined" data-positiony="undefined" data-fullwidth="false" data-mce-src="https://cdn.durable.co/getty/5N9umpbB0cbBZPfG4M8vyzP6tFSvWhBqHedNiJmlnvPJ5Qpl9VWESwi0SO3nLoiW.jpeg" data-mce-style="aspect-ratio: 16/9; object-position: center center;"></figure><h3>The Business Case for Condition-Based Maintenance </h3>The value of CBM lies in its ability to balance reliability and cost efficiency.Traditional preventive maintenance often results in either over-maintenance or under-maintenance. Equipment may be serviced too frequently—wasting resources—or not frequently enough—leading to unexpected failures.Condition-based strategies address this problem by aligning maintenance activity with the actual condition of assets.According to reliability studies, maintenance activities themselves can introduce new failures through human error, improper installation, or contamination during disassembly (Nowlan &amp; Heap, 1978)—this has been estimated at 20% of maintenance interventions. By reducing unnecessary interventions, CBM can therefore improve reliability as well as reduce cost.Organizations adopting condition monitoring programs commonly experience benefits such as:<ul><li>Reduced unplanned downtime</li><li>Extended equipment life</li><li>Improved safety performance</li><li>More efficient use of maintenance resources</li><li>Better planning and scheduling of maintenance work </li></ul><h3>Integrating CBM with Digital Technologies </h3>The rise of Industrial Internet of Things (IIoT) technologies is accelerating the adoption of condition-based strategies.Modern sensors can continuously collect equipment data and transmit it to centralized monitoring platforms. Advanced analytics and machine learning algorithms can then detect anomalies and predict potential failures before they impact operations.This integration enables organizations to move beyond basic condition monitoring toward predictive maintenance, where data models forecast future asset behavior.However, successful CBM programs do not depend solely on technology. They also require strong maintenance fundamentals, including:<ul><li>Structured asset hierarchies</li><li>Accurate maintenance data</li><li>Skilled analysts and technicians</li><li>Effective maintenance planning processes </li></ul>Without these foundations, even the most advanced monitoring systems may fail to deliver meaningful insights.<figure id="figure-6iomo88ndtmmey2wer"><img id="6iomo88ndtmmey2wer" src="https://cdn.durable.co/getty/16hRhi3m01RsQUvWniHbg6Bnfa7dcUhSOz17xJCIK9BCEXPdswjEt1K9tLXdbdhr.jpeg" alt="Big yellow arrow opposite direction with white arrows on asphalt road" title="Big yellow arrow opposite direction with white arrows on asphalt road" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9; object-position: center center;" data-corners="default" data-aspect="16:9" data-caption="" data-positionx="undefined" data-positiony="undefined" data-fullwidth="false" data-mce-src="https://cdn.durable.co/getty/16hRhi3m01RsQUvWniHbg6Bnfa7dcUhSOz17xJCIK9BCEXPdswjEt1K9tLXdbdhr.jpeg" data-mce-style="aspect-ratio: 16/9; object-position: center center;"></figure><h3>Implementation Challenges </h3>Despite its advantages, implementing Condition-Based Maintenance can present challenges.One of the most common barriers is data interpretation. Monitoring systems generate large volumes of information, but distinguishing between normal variation and meaningful fault indicators requires expertise.Another challenge is organizational change. Maintenance teams accustomed to time-based routines may initially resist adopting condition-based strategies.Successful implementation therefore requires not only technology investment but also training, clear processes, and strong leadership support.Organizations that approach CBM as part of a broader reliability strategy—rather than as a standalone technology initiative—are far more likely to achieve sustainable results.<h3>💬 Discussion </h3>How proactive is your organization’s maintenance strategy?Consider the following questions:Is your maintenance program primarily time-based, or do you actively monitor asset condition?Which condition monitoring techniques (vibration, thermography, oil analysis, etc.) have proven most valuable in your organization?What challenges have you encountered when implementing condition-based maintenance?Has condition monitoring helped your team prevent major failures? Share your experience in the comments.What has been the biggest success—or biggest challenge—in moving from preventive maintenance to condition-based maintenance?<figure id="figure-rtcrvtil4ummey5c9x"><img id="rtcrvtil4ummey5c9x" src="https://cdn.durable.co/getty/254t98uMqXcbZLDwYqWpTV8VxCxNdvtySMUsmZWrJnRHYVTcJGtG21vXFWhKjjk6.jpeg" alt="Ripped paper with 'coming soon' text" title="Ripped paper with 'coming soon' text" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9; object-position: center center;" data-corners="default" data-aspect="16:9" data-caption="" data-positionX="undefined" data-positionY="undefined" data-fullWidth="false"/></figure>This article is part of a series exploring how data, digital technologies, and advanced analytics are reshaping modern maintenance and reliability management.Next in the series: The Impact of Big Data on Maintenance, exploring how large-scale operational data is transforming reliability analysis and maintenance decision-making.<h3>References </h3>Mobley, R.

Condition-Based Maintenance—A Proactive Approach

Businessman holding and showing the best quality assurance with golden five stars for guarantee product and ISO service concept.

Maintenance organizations today generate enormous volumes of data. Work orders, failure reports, inspection records, condition monitoring results, and operational parameters all flow through modern CMMS and EAM systems. Yet many organizations still struggle to translate this information into clear, actionable insights.The issue is rarely the absence of data. More often, it is the absence of the right metrics.Key performance indicators (KPIs) help maintenance leaders cut through complexity and focus on what truly matters: reliability, cost control, and operational performance. When selected correctly, KPIs provide a clear line of sight between maintenance activities and business outcomes.However, not all metrics are equally useful. Tracking dozens of indicators can dilute focus and create confusion. The most effective maintenance organizations concentrate on a small number of high-impact KPIs that directly influence asset performance and operational risk.Below are five essential maintenance KPIs that reliability leaders should monitor consistently.<figure id="figure-jowgjbsjnsmmdoh394"><img id="jowgjbsjnsmmdoh394" src="https://cdn.durable.co/getty/28ZHcQi9y35vt4ne1EO35e5BSxCmkV845AAEoBfB0Im5Z175DyR9M3EImawBuoAu.jpeg" alt="KPI key performance indicator The concept of analyzing dashboards of key performance indicators (KPIs) using Business Intelligence (BI) systems to measure performance against planned targets, success." title="KPI key performance indicator The concept of analyzing dashboards of key performance indicators (KPIs) using Business Intelligence (BI) systems to measure performance against planned targets, success." class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9; object-position: center center;" data-corners="default" data-aspect="16:9" data-caption="" data-positionx="undefined" data-positiony="undefined" data-fullwidth="false" data-mce-src="https://cdn.durable.co/getty/28ZHcQi9y35vt4ne1EO35e5BSxCmkV845AAEoBfB0Im5Z175DyR9M3EImawBuoAu.jpeg" data-mce-style="aspect-ratio: 16/9; object-position: center center;"></figure><h3> 1. Overall Equipment Effectiveness (OEE) </h3>OEE is widely recognized as one of the most comprehensive measures of manufacturing performance. It evaluates how effectively equipment is utilized by combining three key factors: availability, performance, and quality.OEE answers a simple but powerful question:How much of the equipment’s true production potential is being realized?When maintenance issues increase downtime, availability decreases and OEE drops. Likewise, equipment operating below design speed or producing defects also affects the metric.By monitoring OEE, maintenance leaders can identify whether reliability issues are impacting production and prioritize improvement efforts accordingly. According to the Lean Enterprise Institute, world-class organizations typically achieve OEE levels above 85% (Lean Enterprise Institute, 2017).<h3>&nbsp;2. Mean Time Between Failures (MTBF) </h3>MTBF measures the average time an asset operates before experiencing a failure. It is one of the most fundamental reliability indicators and provides a direct view of asset health.If MTBF is increasing, reliability improvements are working. If it is declining, failures are becoming more frequent and further investigation is required.MTBF is particularly valuable when analyzing:Recurring equipment failures Reliability improvements following maintenance changes The effectiveness of preventive or predictive strategies However, MTBF should not be analyzed in isolation. It must be supported by accurate failure reporting and consistent data capture. Standards such as ISO 14224 emphasize the importance of structured reliability data for meaningful analysis (ISO, 2016).<figure id="figure-n4zrrkzs5bmmdoin4u"><img id="n4zrrkzs5bmmdoin4u" src="https://cdn.durable.co/getty/18X18ftO58tPjL4fbOqcU4ivLqXstucEvG1FrjPs0s1s5fW3xSRJA0Dq2vseXh4h.jpeg" alt="Mechanic testing diesel injector" title="Mechanic testing diesel injector" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9; object-position: center center;" data-corners="default" data-aspect="16:9" data-caption="" data-positionx="undefined" data-positiony="undefined" data-fullwidth="false" data-mce-src="https://cdn.durable.co/getty/18X18ftO58tPjL4fbOqcU4ivLqXstucEvG1FrjPs0s1s5fW3xSRJA0Dq2vseXh4h.jpeg" data-mce-style="aspect-ratio: 16/9; object-position: center center;"></figure><h3>3. Mean Time to Repair (MTTR) </h3>While MTBF measures how often failures occur, Mean Time to Repair (MTTR) measures how quickly the organization can respond and restore equipment to operation.A lower MTTR indicates efficient troubleshooting, well-prepared maintenance teams, and effective spare parts management.Several factors influence MTTR, including:<ul><li>Technician skill levels</li><li>Availability of spare parts</li><li>Quality of maintenance procedures</li><li>Accessibility of equipment</li><li>Diagnostic tools and documentation </li></ul>Reducing MTTR is often one of the fastest ways to improve operational availability. Even when failures occur, rapid recovery minimizes production impact.<h3>4. Planned vs. Unplanned Maintenance </h3>This KPI measures the percentage of maintenance work that is planned and scheduled versus emergency or reactive work.World-class maintenance organizations typically aim for 80–90% planned maintenance (Mobley, 2002).Why does this matter?Reactive maintenance is almost always more expensive. Emergency work often leads to:<ul><li>Production disruption</li><li>Overtime labor</li><li>Increased safety risk</li><li>Secondary equipment damage </li></ul>A high percentage of planned work indicates strong maintenance planning, effective preventive strategies, and improved asset reliability.Conversely, if unplanned work dominates the workload, it often signals underlying reliability issues or poor maintenance planning processes.<figure id="figure-955wx5jnrsmmdomnit"><img id="955wx5jnrsmmdomnit" src="https://cdn.durable.co/getty/39CXyfiK0psqBSxSrtcf3r0u2KR0BZtlIo18jmQOo7KZVvIHAI6iJgiNVfLz0YNp.jpeg" alt="Systematic Planning and Project Management" title="Systematic Planning and Project Management" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9; object-position: center center;" data-corners="default" data-aspect="16:9" data-caption="" data-positionx="undefined" data-positiony="undefined" data-fullwidth="false" data-mce-src="https://cdn.durable.co/getty/39CXyfiK0psqBSxSrtcf3r0u2KR0BZtlIo18jmQOo7KZVvIHAI6iJgiNVfLz0YNp.jpeg" data-mce-style="aspect-ratio: 16/9; object-position: center center;"></figure><h3> 5. Maintenance Cost as a Percentage of Asset Replacement Value (ARV) </h3>Maintenance leaders must also understand financial performance.One widely used benchmark is maintenance cost as a percentage of Asset Replacement Value (ARV). This KPI compares annual maintenance spending against the estimated cost of replacing the asset base.Typical industry benchmarks suggest maintenance costs should fall within 2–5% of ARV, depending on the industry and asset intensity (Campbell &amp; Reyes-Picknell, 2015).If maintenance spending significantly exceeds this range, organizations may be dealing with aging assets, poor maintenance strategies, or inefficient processes. Conversely, extremely low spending may indicate under-maintenance, which can lead to future reliability problems.<h3>Turning Metrics into Meaningful Insight </h3>The true value of KPIs lies not in reporting numbers, but in driving improvement.Maintenance leaders should treat KPIs as diagnostic tools rather than performance scorecards. When a metric changes, the key question is always:What is the data telling us about our assets and our processes?For example:<ul><li>Declining MTBF may indicate recurring design or operating issues. </li><li>Rising MTTR may signal training gaps or spare parts shortages. </li><li>Increasing reactive maintenance may reveal weaknesses in preventive maintenance programs. </li></ul>By consistently reviewing and acting on these metrics, organizations can build a more proactive and reliability-focused maintenance culture.As noted by Davenport and Harris, organizations that consistently outperform competitors are those that integrate analytics directly into operational decision-making (Davenport &amp; Harris, 2017).<figure id="figure-op1sg9lqtmmdonyjr"><img id="op1sg9lqtmmdonyjr" src="https://cdn.durable.co/getty/0k4NW9QUDCcH65lKTZ4aduEFF9X8O8Nk5X0nyiKKZY9VrgnK7LTCXHeeXKXUrW0O.jpeg" alt="Colorful Speech Bubbles On Blue Background" title="Colorful Speech Bubbles On Blue Background" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9; object-position: center center;" data-corners="default" data-aspect="16:9" data-caption="" data-positionx="undefined" data-positiony="undefined" data-fullwidth="false" data-mce-src="https://cdn.durable.co/getty/0k4NW9QUDCcH65lKTZ4aduEFF9X8O8Nk5X0nyiKKZY9VrgnK7LTCXHeeXKXUrW0O.jpeg" data-mce-style="aspect-ratio: 16/9; object-position: center center;"></figure><h3>💬 Discussion</h3>How does your organization measure maintenance performance?Consider the following questions:<ul><li>Which maintenance KPIs are most important in your organization?</li><li>Are your metrics focused on reliability improvement or simply reporting activity?</li><li>Do maintenance teams clearly understand how their work influences these KPIs?</li><li>Which metric has delivered the greatest insight or improvement in your maintenance strategy?</li></ul>Share your experience in the comments.<ul><li>What KPI has had the biggest impact on improving reliability or reducing downtime in your organization?</li></ul>This article is part of a series exploring how data, digital technologies, and advanced analytics are reshaping modern maintenance and reliability management.<h3>&nbsp;References </h3>Campbell, J.

5 Maintenance KPIs Every Reliability Leader Should Track

Network of AI Coding Agents Collaborating on Software Development

In many organizations, maintenance decisions are still driven by habit, intuition, or legacy practices. Work orders are executed because “that’s how it’s always been done,” preventive tasks are scheduled without clear justification, and failures are investigated only after they cause disruption.But the industrial landscape is changing. Asset-intensive organizations now generate vast volumes of operational data—from sensors, condition monitoring systems, CMMS platforms, inspection reports, and operator observations. The question is no longer whether data exists. The real question is whether organizations are actually using that data to make better maintenance decisions.Organizations that effectively leverage maintenance data consistently outperform those that do not. Research suggests that data-driven maintenance strategies can reduce unplanned downtime by up to 30–50% while lowering maintenance costs by 10–20% (McKinsey &amp; Company, 2018). In short, data turns maintenance from a reactive cost center into a strategic contributor to operational performance.<h3>The Shift from Reactive to Insight-Driven Maintenance </h3>Historically, maintenance evolved through three broad phases:<ol><li>Reactive maintenance – fix it when it breaks.</li><li>Preventive maintenance – scheduled tasks based on time or usage.</li><li>Predictive and data-driven maintenance<ol><li>Interventions triggered by condition, performance trends, and analytics.</li></ol></li></ol>Most organizations today operate somewhere between preventive and predictive maintenance. The problem is not technology—it is the effective use of information.A modern maintenance function should continuously answer four core questions:<ol><li>What assets fail most frequently?</li><li>What failures cause the greatest operational impact?</li><li>What maintenance tasks actually prevent those failures?</li><li>Where should we invest resources to deliver the greatest reliability improvement?</li></ol>Without reliable data, these questions are answered by opinion. With data, they are answered with evidence.<figure id="figure-cq2p8fzdz6mmdnkzi1"><img id="cq2p8fzdz6mmdnkzi1" src="https://cdn.durable.co/getty/29YnV67lA3LREMv9O8s2sGmxE4nGHt00yVc6CcqfHnhnhQARs5c07AKHKcRfb00V.jpeg" alt="Using artificial intelligence (AI) for improving efficiency and reducing costs.

If failure data, work orders, and asset hierarchies are poorly defined, analytics will produce misleading conclusions. As the well-known management principle states: “You cannot manage what you cannot measure.” (Kaplan &amp; Norton, 1996).Several elements are critical:1. Asset hierarchy and data structure A well-defined asset hierarchy in the CMMS or EAM system enables accurate tracking of failures, maintenance costs, and reliability trends. Without this structure, organizations cannot reliably identify problem assets or systems.2. Failure coding and reliability data Standardized failure codes allow organizations to analyze failure patterns and identify root causes. Standards such as ISO 14224 provide guidance on collecting reliability and maintenance data for industrial equipment (ISO, 2016).3. Data quality and discipline Incomplete work orders, vague failure descriptions, or inconsistent coding undermine the entire process. Data quality is often the single biggest barrier to effective analytics.4. Analytics and visualization Dashboards, reliability models, and statistical analysis convert raw data into insights. These tools highlight trends that would otherwise remain invisible.<figure id="figure-brxlni2awcmmdnlyx1"><img id="brxlni2awcmmdnlyx1" src="https://cdn.durable.co/getty/1dQB3RjZ0rwViAyhAM1Vi9Eixpd0b11xpbeM5LFYHhp20XCZnv0ANODyFn43TPH0.jpeg" alt="Technical Solution and Repair Process Animation" title="Technical Solution and Repair Process Animation" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9; object-position: center center;" data-corners="default" data-aspect="16:9" data-caption="" data-positionx="undefined" data-positiony="undefined" data-fullwidth="false" data-mce-src="https://cdn.durable.co/getty/1dQB3RjZ0rwViAyhAM1Vi9Eixpd0b11xpbeM5LFYHhp20XCZnv0ANODyFn43TPH0.jpeg" data-mce-style="aspect-ratio: 16/9; object-position: center center;"></figure><h3>From Data to Action </h3>Collecting data is only the first step. The real value comes when insights lead to action.For example, consider a plant experiencing frequent pump failures. Maintenance teams may initially assume the pumps are poorly designed or operating outside specification. However, analysis of work order data might reveal that the failures occur shortly after maintenance interventions—indicating installation errors or alignment issues.This insight changes the solution completely. Instead of replacing pumps, the organization invests in improved maintenance procedures and technician training.This is the power of data-driven decision making.Similarly, reliability analytics can help organizations:<ul><li>Prioritize critical assets using risk-based approaches</li><li>Optimize preventive maintenance intervals</li><li>Identify bad actors in the asset population</li><li>Evaluate the effectiveness of maintenance strategies</li><li>Support predictive maintenance and condition monitoring programs </li></ul>The result is a maintenance strategy that is not based on guesswork, but on measurable performance and evidence.<h3>The Role of Digital Transformation </h3>Industry 4.0 technologies are accelerating this shift. Sensors, Industrial Internet of Things (IIoT) platforms, and advanced analytics now provide real-time insights into asset health and performance.Predictive analytics can identify abnormal equipment behavior long before failure occurs. Machine learning models can analyze vibration, temperature, and process data to detect emerging issues. Digital twins can simulate asset performance under different operating conditions.However, technology alone does not solve the problem. Successful organizations combine digital tools with strong maintenance fundamentals—structured data, reliability methodologies, and disciplined work management.As Davenport and Harris argue, organizations that compete on analytics develop a culture where decisions are systematically informed by data rather than intuition (Davenport &amp; Harris, 2017).<figure id="figure-2rr83ye1y3mmdnoqmj"><img id="2rr83ye1y3mmdnoqmj" src="https://cdn.durable.co/getty/238XthwFjaEplPbTGlWbBMiBkcRYjQZkQO51WCdGvUe0LY7X49hmNlbVyWt3mI9E.jpeg" alt="Digital Transformation Concept of digitalization of technology business processes.

It requires cultural change.Maintenance teams must understand that accurate data capture is not administrative overhead—it is the foundation of better decisions. Leaders must encourage curiosity, asking not only what happened, but also why it happened and what the data is telling us.Over time, this mindset transforms maintenance from a reactive function into a strategic reliability partner for operations.<h3>💬 Discussion How effectively is your organization using maintenance data today?</h3>Consider these questions:<ul><li>Do you have reliable failure data in your CMMS or EAM system?</li><li>Are maintenance strategies based on evidence—or historical practice?</li><li>Which assets generate the most maintenance cost, and do you know why?</li><li>Is your organization capturing the right data to support predictive maintenance?</li></ul>Share your experience in the comments.<ul><li>What has been the biggest challenge—or biggest success—when using data to improve maintenance performance?</li></ul>This article is part of a series exploring how data, digital technologies, and advanced analytics are reshaping modern maintenance and reliability management.<h3>References </h3>Davenport, T.
