Summary – Predictive maintenance is often associated with costly IoT sensors, yet industrial SMEs already possess unused failure histories, reports, and logs to anticipate breakdowns. By structuring and cleaning this passive data, standardizing manual inspections, and deploying a CMMS, they can generate reliable indicators within weeks and cut unplanned downtime by 20–40%. This pragmatic, low-cost, rapid-to-implement approach offers immediate ROI while preparing the company for future IoT scale-up.
In decision-makers’ minds, predictive maintenance often conjures images of ultramodern factories bristling with sensors and sophisticated algorithms. Yet many Swiss industrial SMEs already possess untapped assets: failure histories, service reports, operating hours logs…
By structuring these passive data, they can easily gain an anticipatory view of failures without a massive IoT investment. This pragmatic approach offers a quick return on investment, integrates with existing practices, and prepares the company for a potential technological scale-up. Without disrupting the organization or relying on a single vendor, this first digital step becomes a true modernization lever.
Exploring and Structuring Passive Data
You already have valuable information without IoT sensors. It’s by structuring your histories and logs that your first predictive indicators emerge.This initial work, quick and low-cost, provides a solid foundation to reduce downtime and prepare your plant’s digital future.
Identifying Existing Data Sources
Every machine leaves traces of its activity. Paper reports written after each intervention, error logs generated by PLCs, and production cycle records all serve as entry points for predictive analysis. These often overlooked elements reveal recurring anomalies and component lifespans.
In many workshops, technicians manually record operating hours and maintenance events. Even imperfect, these archives offer a panorama of equipment reliability over time. The key is to gather and digitize them to extract trends.
A quick mapping of data sources highlights systems with high forecasting potential. By consolidating PDFs, spreadsheets, and logbooks in a central system, you limit information loss and streamline the next step: data cleansing and organization.
Structuring and Cleansing Histories
Data quality is crucial for building robust predictive models. You must standardize formats, eliminate duplicates, and reconstruct intervention timelines. A thorough data cleansing ensures temporal consistency and removes inconsistencies that could skew results.
An SME specializing in machine tools undertook this approach by centralizing twelve months of paper reports into a simple database. After deduplicating and harmonizing labels, it discovered that 40 % of stoppages were linked to just two components. This first analysis enabled quick corrective actions.
Once this step is complete, your data are ready to be leveraged by visualization tools or even lightweight scripts. You thus obtain your first trend indicators, without deploying costly sensors.
Initial Analysis Models Without IoT
With quality historical data, simple statistical methods can predict failures. Degradation curves, calculated from operating hours versus reported incidents, often suffice to detect critical wear before a breakdown.
These basic models, implemented in a few days, enabled an industrial equipment manufacturer to reduce unplanned downtime by 20 %. The company also found that the wear rate of a hydraulic seal could be predicted with 85 % reliability, without onboard sensors.
Buoyed by these early successes, the team continued refining its forecasts by incorporating production seasonality and spare-parts availability, using process intelligence methods. This experimentation phase validates the approach and builds confidence before considering an IoT extension.
Operational Rigor: A More Powerful Asset Than Sensors
Predictive maintenance relies first on repeated, structured inspections, not on the volume of real-time data collected.Regular checks, conducted via clear protocols and supported by low-tech tools, are enough to establish reliable condition monitoring.
Structured Manual Inspections
Visual walkthroughs and manual readings, when standardized, offer a detailed snapshot of machine health. Precise checklists allow you to record temperature, wear levels, or leaks at the earliest sign of anomaly.
Drafting a clear inspection protocol, with regular intervals, establishes an indispensable discipline. Repeating measurements reveals subtle variations, often precursors to imminent failure.
By relying on these readings, you gradually build a condition-monitoring database. Each entry feeds a usable history that complements the passive data collected earlier.
Low-Tech Monitoring Tools
Simple instruments—like handheld thermal cameras or portable vibration recorders—enrich the setup without requiring fixed installations. These tools deploy in minutes and provide reliable on-site measurements.
A construction SME implemented a portable vibration analysis protocol, used by operators to detect rotor imbalances in concrete pumps. By comparing readings at three-month intervals, it anticipated misalignment before it caused bearing failure.
The advantage of these low-tech solutions is that they don’t create dependence on a complex IoT network. Data are stored manually or quickly imported into a CMMS for tracking.
Process Standardization and Training
To ensure inspection quality, operators must be trained on the new protocols. A short training session on recognizing degradation signs (unusual noises, overheating) turns each team member into a human sensor.
Simple check sheets, completed on tablet or paper, guarantee traceability and ease analysis. Reporting becomes transparent and accessible to all teams, reinforcing a proactive maintenance culture.
This organizational work fosters essential reflexes: Are inspection intervals respected? Are anomalies reported immediately? Systematic answers to these questions feed your predictive foundation.

A Fast, Controlled ROI for Industrial SMEs
This progressive approach launches a predictive initiative in weeks on a limited budget.No technological lock-in, low risk, and tangible benefits before even considering an IoT rollout.
Reduced Costs and Agile Deployment
Relying on internal resources and low-cost tools, the dedicated budget remains contained. It can cover a CMMS license, a few portable sensors, and operator training, avoiding mass sensor purchases.
Setup time is measured in weeks: from collecting histories to the first analysis, the pilot scope is quickly operational. Performance gains and downtime reductions become evident from the first iterations.
Integration with Existing Practices
The key to success lies in embedding the predictive approach into teams’ daily routines. Traditional maintenance reports evolve into digital forms without changing work habits.
Scheduled interventions now include systematic condition checks. Technician adoption is eased because the tools remain familiar and procedures progressively enriched.
This reduces change resistance and keeps the focus on the essentials: preventing failures rather than reacting to unexpected downtime.
Preparation for a Future IoT Phase
Phase 1 formalizes processes, documents key indicators, and validates a data governance model. You then know exactly where and how to deploy sensors for optimal impact.
Beyond initial gains, this approach prepares infrastructure and internal culture for a later IoT rollout. Technological choices will be guided by precise knowledge of failure points.
Your plant gains digital maturity, minimizing the risk of premature or ill-suited investments.
Central Role of Human Factor and CMMS
Operators are your first sensors: their perceptions enrich predictive insights beyond what technology can detect.The CMMS becomes the backbone of the system, centralizing inspections, automating reminders, and logging every action.
Operators as First Sensors
Technicians hear vibrations, feel mechanical play, and detect temperature changes before any sensor. Their involvement bolsters forecast reliability.
It is essential to train them to recognize weak signals: unusual noises, burning smells, or abnormal mechanical behavior. These early clues complement objective readings and alert the maintenance team.
Valuing their role creates a collaborative dynamic: each report becomes a potential alert that prevents costly downtime.
Key Role of CMMS in Structuring
The CMMS centralizes checklists, intervention histories, and recorded trends. It automates inspection reminders and tracks indicator evolution by machine.
Even without IoT data, the CMMS provides a clear dashboard: inspection compliance rates, anomaly frequency, and resolution times. These metrics form the backbone of a structured predictive approach.
This organizational work fosters a data culture. Teams make it a habit to log every observation, track indicators, and use reports to prioritize actions.
Data Culture and Progressive Evolution
The CMMS promotes a data-driven culture. Teams habitually record observations, monitor indicators, and rely on reports to guide priorities.
This discipline paves the way for gradual IoT sensor integration, which will enrich the existing system rather than disrupt teams.
Your predictive maintenance thus evolves organically, from paper to digital, without abrupt breaks.
Turn Predictive Maintenance into an Operational Advantage
Leveraging your passive data, structuring regular inspections, deploying a CMMS, and involving your operators form a pragmatic, low-cost path to modernize your workshop. You achieve a quick ROI, reduce unplanned downtime, and prepare the ground for future IoT sensors on a solid foundation.
