How to Use Data to Guide Your Predictive Maintenance Rollout Plan

Predictive maintenance is revolutionising industrial operations, helping manufacturers minimise unplanned downtime, reduce maintenance costs, and optimise asset performance. However, the success of a predictive maintenance strategy depends on the availability, accuracy, and analysis of data.

One of the most common questions we receive is: What data sources should we examine as a site considering predictive maintenance to determine if it's the right fit for us?

Well, here's our answer.

Rolling out predictive maintenance requires a structured approach—one that leverages various data sources to ensure that maintenance efforts are targeted at the right assets, at the right time, with the right actions. In this guide, we’ll explore the critical data sources that should inform your predictive maintenance rollout and how to use them to maximise the return on your investment.

1. CMMS Data: The Foundation of Maintenance Insights

A Computerised Maintenance Management System (CMMS) is the backbone of maintenance data in most industrial facilities. It contains historical records of maintenance activities, asset health, and work orders. Here’s how to leverage CMMS data:

Asset Criticality Matrix

Not all assets require predictive maintenance—some are more critical than others. Use your CMMS to create an asset criticality matrix, which ranks equipment based on factors such as:

  • Production impact (does failure cause line stoppage?)
  • Repair costs and lead times for spare parts
  • Health and safety risks
  • Frequency and severity of past failures

Downtime Hours per Asset

Your CMMS logs downtime for each asset. By analysing this data, you can:

  • Identify the assets responsible for the most lost production time
  • Quantify downtime costs (e.g., $ per hour of lost production)
  • Prioritise predictive maintenance efforts where it will have the biggest ROI

Failure Modes and Trends

Understanding which failure modes occur most often enables you to focus predictive maintenance efforts on solving recurring issues. CMMS data can help answer:

  • What are the most common failure types for each asset?
  • Do failures follow a seasonal or operational pattern?
  • Are certain failure modes more likely to occur in specific conditions (e.g., humidity, temperature fluctuations)?

Work Order History

A deep dive into historical work orders can reveal inefficiencies in your current maintenance strategy. Look for:

  • Reactive vs. preventive maintenance ratios (how often are you fixing breakdowns vs. performing scheduled PMs?)
  • Time between failures (Mean Time Between Failures - MTBF)
  • Mean Time to Repair (MTTR)
  • Frequent failure causes and whether past fixes have been effective

2. Capturing Anecdotal Data from Site Conversations

While digital records are valuable, the insights from site personnel—engineers, operators, and maintenance staff—are just as critical in shaping a predictive maintenance strategy.

Conversations with Operators and Technicians

Operators and technicians interact with the equipment daily. Engaging them in structured conversations can uncover:

  • Repeated adjustments they make to keep equipment running smoothly
  • Unusual noises, vibrations, or performance dips they have observed
  • Workarounds they rely on when equipment isn’t functioning correctly
  • Situations where past maintenance actions did not resolve the issue long-term

Investigating Past Near-Misses and Failures

By speaking with maintenance teams, you can build a richer understanding of past failures and near-misses that might not be well-documented in CMMS data:

  • Was there an early warning sign before the failure that was ignored or unrecognised?
  • How often have teams replaced the same component before realising the root cause was elsewhere?
  • Have certain failures always happened after specific production conditions?

Identifying Manual Data Logging Gaps

Many sites still rely on paper-based logs or informal reporting, which means some failure patterns are not captured digitally. Work with teams to:

  • Encourage systematic logging of manual observations
  • Digitise important handwritten records where feasible
  • Train operators on what failure symptoms to report consistently

Confirming Maintenance Work Effectiveness

Maintenance teams have hands-on experience with past repairs. Their insights can help determine:

  • Whether prior repairs solved the root cause or just the symptoms
  • Which assets frequently require rework or additional adjustments
  • Where maintenance activities could be optimised to prevent recurring breakdowns

3. SCADA, PLC & Historian Data: Leveraging Process Control Systems

Most industrial sites have Supervisory Control and Data Acquisition (SCADA) systems, Programmable Logic Controllers (PLCs), and Data Historians that store vast amounts of operational data.

Process Variables for Predictive Maintenance

SCADA and PLCs track key process variables that can be used for predictive insights:

  • Pressure anomalies in hydraulic and pneumatic systems
  • Flow rates indicating pump or valve blockages
  • Temperature profiles for heat exchangers and cooling systems

Combining Process Data with Manual Insights

By integrating SCADA/PLC data with anecdotal feedback from operators, you can:

  • Detect process conditions that contribute to wear and tear
  • Identify correlations between operating conditions and asset failures
  • Optimise predictive maintenance models using a combination of structured and unstructured data

4. Operator & Maintenance Team Feedback

Not all failure patterns are captured in digital data—some are best understood by those closest to the equipment.

Capturing Tribal Knowledge

Operators and maintenance personnel often notice early warning signs of failure that may not be recorded in data systems. This could include:

  • Unusual smells (burning, overheating insulation)
  • Changes in machine behaviour (increased noise, slower operation)
  • Frequent manual adjustments required to keep equipment running

Digital Logs & Mobile Apps

Encouraging operators to log observations in a mobile app or digital system ensures valuable insights are recorded for predictive analysis.

5. Building Meaningful Connections Beyond Your Site

Predictive maintenance insights don’t just come from internal data—they can also be enriched by learning from industry peers and experts outside of your site.

Networking with Site Leaders & Reliability Professionals

Engaging with maintenance and reliability professionals at other facilities can provide new perspectives on:

  • Best practices in predictive maintenance implementation
  • Lessons learned from successful and unsuccessful rollout strategies
  • Innovative technologies and methodologies being adopted in the industry

Attending Industry Conferences & Webinars

Industry events and online forums offer valuable opportunities to:

  • Hear real-world case studies from maintenance leaders
  • Discover emerging trends in predictive maintenance technology
  • Engage in discussions on maintenance challenges and solutions

Benchmarking Against Similar Sites

Comparing your maintenance performance with similar sites can help identify:

  • Areas where your predictive maintenance efforts can improve
  • Key performance indicators (KPIs) that are leading indicators of success
  • Strategies to enhance collaboration across different sites within your organisation

Leveraging Online Communities & Forums

Online platforms dedicated to industrial maintenance, such as LinkedIn groups and specialised forums, provide an accessible way to:

  • Exchange knowledge with industry peers
  • Stay updated on technological advancements
  • Seek advice on predictive maintenance challenges
