Field Mobility: Capturing Information at the Right Time, in the Right Place

A technician finishes an intervention on a heat exchanger. He has replaced a seal, checked three control points, and made a mental note that the inlet fitting shows signs of corrosion. He closes the panel, moves on to the next machine. In the evening, back at the office, he fills out his report. Duration? About two hours. Parts? He remembers the seal, not the reference number. The observation about the corrosion? Forgotten.

This scenario repeats dozens of times a day in most industrial sites. The information exists — in the technician's head, at the moment of the intervention. But it gets lost between the field and the system, because data entry happens too late, on the wrong medium, in the wrong context.

The Cost of Lost Information

When a technician enters interventions after the fact, three types of information degrade.

Intervention durations are rounded or estimated. A technician who spent 45 minutes on a machine writes "1 hour" because it's simpler. Multiplied across all the month's interventions, the discrepancy skews labor costs and prevents reliable planning

‍Consumed spare parts are incompletely recorded. The technician replaced three components but only declares one — the most obvious. The stock displayed in the CMMS no longer matches actual stock. Replenishment orders arrive too late.

Field observations disappear. An abnormal vibration, an unusual noise, the beginning of a leak — these weak signals are the most valuable for preventive maintenance, and they're the first to be forgotten when data entry is deferred.

Bringing Data Entry Closer to the Moment of Intervention

The answer isn't to ask technicians to fill out their forms better. It's to give them a tool that works in the field, at the moment of the intervention, without a detour through the office.

A technician who scans the QR code on a piece of equipment instantly accesses its record: intervention history, current tasks, associated spare parts. He doesn't need to search for the right equipment in a list — the scan identifies it directly. If a preventive task is assigned, he opens it, follows the checklist, and logs his activity with the duration and consumed spare parts — all from his phone, standing in front of the machine.

In Mobility Work, the technician logs an activity in a few steps: description of the intervention, actual duration, spare parts used, counter reading if applicable. Voice input allows him to dictate an observation without typing on a keyboard. The application also works offline — if network coverage is poor in the workshop, data syncs automatically when the connection returns.

The Impact on the Entire Decision Chain

When field data entry is reliable, downstream indicators become reliable too. Labor costs per equipment reflect reality. The spare parts stock is up to date. The equipment history is complete and usable.

The maintenance manager who opens the analytics dashboard sees data that corresponds to what actually happened in the field — not to what technicians remembered in the evening. The difference between the two is often considerable.

Three Actions to Improve Field Data Capture

Deploy QR codes on your critical equipment. Start with the machines most frequently maintained. The QR code eliminates the search step and reduces the risk of entry on the wrong equipment. A technician who scans is a technician who enters data in the right place.

Train technicians to enter data immediately, not at the end of the day. Deferred entry is the primary cause of inaccurate data. Show that entering from a phone takes less than two minutes — often less than re-entering at the office in the evening.

Use checklists to structure preventive interventions. A checklist guides the technician point by point and produces standardized data. It replaces the free-form report — faster for the technician, more usable for the manager.
