Start with the customer and operating promise
FSM begins when a team accepts responsibility for a service outcome. The system must preserve who requested the work, where it will happen, what equipment or service is involved, how urgent it is, what was promised, and who owns the next step.
- Customer, contact, site, and installed-equipment context.
- Issue, impact, priority, service coverage, and promised response.
- Coordinator, appointment, work order, and current owner.
