Build around the service lifecycle
A useful system records customer assets, contracts, service history, priorities, skills, locations, planned visits, parts, time, evidence, and sign-off. Dispatch becomes more reliable when this context is visible before assignment.
Measure outcomes the operation can act on
Track response time, first-time completion, repeat visits, technician utilization, parts consumption, contract profitability, and unresolved exceptions. Use a small set of definitions the team can trust.
