Field service documentation is the hardest kind
Heavy equipment repairs happen where the machine is: a jobsite, a quarry, a pipeline right-of-way, a bridge deck. The technician is often alone, often out of coverage, and always working against the clock because the machine is holding up production. Documentation is the first thing to go.
The result is a service department that knows what it billed but not what it did. Field techs call in a verbal summary, the writer types an approximation, and the photos — if anyone took them — never make it off the phone. When the customer questions the invoice, or the manufacturer asks for failure evidence on a component claim, there is nothing to point to.
Shop and field also fall out of sync. A machine that was diagnosed roadside arrives at the shop with no record of what the field tech already ruled out, so the shop repeats the diagnosis and the customer pays for it twice.
