Field capture without signal: what we learned from 10 million pieces of evidence

Your technician opens a service order in the basement of a plant. Your supervisor inspects a site where the phone gets no network. Your sales rep or merchandiser visits a store with one bar of signal. In all three cases the same thing happens: if the app needs a connection, the record is left for later, and later is often never.

For any company with people in the field, that is not a technical detail. It is the difference between knowing today what happened at each visit or finding out weeks later, when it can no longer be fixed.

For more than 700 days we ran the field capture platform of a global tobacco company in Mexico, with merchandisers in stores across the country. These are the decisions that mattered most, and they hold just as well for a service order, an inspection or a delivery.

1. The app has to work offline

In this case, the merchandiser captures and takes photos inside the store even without coverage. Everything is stored on the phone and syncs by itself, securely, once signal is back. They leave with their route already loaded, so they do not need a connection to know what to visit either.

If the app depends on signal, field work depends on luck.

2. Every capture with its evidence

A report without a photo can be argued; one with a photo cannot. Every capture is tied to its photo evidence for later audit. In this operation that is already more than 10 million photos, each with its visit.

The same goes for the photo of the repaired equipment, the finished site or the delivered goods.

3. Size it for the peak, not for the average

Field work does not warn you before it grows: peak season, month end, a campaign. The system holds peaks of 400,000 to 500,000 records a day without going down, which is exactly when the data matters most.

4. Forms that operations changes, not the programmer

Surveys are created, planned and scheduled by store chain and by route from the platform, and in this case the trade marketing team runs them. When what needs checking changes, capture changes the same day, without waiting for a new version of the app.

5. See the day's work the same day

With real-time analytics, the team decides on what happened today: more than 1.5 million visits and more than 5 million surveys processed, with more than 500 active users a day.

It was not a pilot

It was sustained production at national scale. If your field team still reports on paper, in spreadsheets or over WhatsApp once they finally get signal, tell us how your team works today: the initial analysis of your idea is immediate.
