Field-service app for a manufacturer's engineers

The client is a UK manufacturer with a field team of engineers working across plants and remote sites, often with poor or no connectivity. Their productivity is shaped as much by paperwork and travel as by the work itself.

Engineers were capturing jobs on paper on site and re-entering the details back at the depot, a double-handling step that cost time and introduced errors.

Engineers worked in plants and remote sites with no reliable signal, then lost time re-entering paperwork back at the depot. The lack of connectivity on site meant the job could not be closed where it was done.

The double handling delayed job closure and introduced transcription errors, each of which had to be found and fixed downstream. Work done well in the field was being degraded by the admin around it.

The manufacturer needed an app that worked fully offline and captured the job once, on site, without losing anything. Reliability in the absence of a network was the central requirement.

We built an offline-first app that treats the device as the source of truth on site, so engineers capture the whole job without a connection. Designing for offline as the default, not the exception, is what made it dependable in the field.

When signal returns it syncs cleanly, resolving conflicts deterministically so no update is ever silently lost. Trustworthy sync is essential when a device may be offline for hours.

That removed the depot re-keying step entirely and closed jobs at the point of work. We tested against the messy reality of intermittent connectivity rather than a lab network, so it held up where it mattered.
