What Is Field Service Management (FSM)?

Short answer: Field service management (FSM) is how a business plans and runs work done at the customer's location rather than in its own building: taking requests, scheduling and dispatching technicians, tracking them in the field, recording the work, and billing. In mobile diesel and heavy-equipment repair, it covers road calls, yard work and job-site repairs.

The parts of FSM

  • Intake. Calls and requests become jobs with location and details.
  • Scheduling and dispatch. Choosing the technician by skills, availability and drive time.
  • Mobile work. Technicians see the job, update status, take photos and record findings on a phone.
  • Parts. Tracking stock on each service truck.
  • Customer updates. On-the-way messages and approvals.
  • Billing. Invoices and payment from the field.
  • Reporting. Response times, hours and revenue.

See field service and diesel field service software.

FSM in diesel repair

General FSM tools are built for trades such as HVAC or plumbing. Diesel and heavy-equipment work adds unit numbers and VINs, repair lines in the 3 Cs format, inspections, fleet terms and PM schedules. A road call for a tractor on the shoulder is also more urgent than most service visits. See how to dispatch mobile diesel technicians.

Why it matters

In field work, time between the call and the technician on site is the main thing the customer feels. Good FSM cuts that time, keeps the customer informed, and makes sure work done in the field reaches an invoice the same day.

FSM and shop software

Many repair businesses do both field and bay work. They need FSM features such as dispatch and mobile work alongside shop features such as bays, parts and work orders, in one system. See shop management software.

Is a mobile mechanic business a field service business?
