SLA Definition and Measurement Framework
Effective SLA tracking starts with unambiguous definitions of what is measured, how it is measured, and what thresholds define compliance. Response time, resolution time, and availability are the three most common SLA metrics in field service. Each metric requires a clear start event, stop event, and clock rules (business hours vs.
calendar hours, pause conditions, exclusion periods).
- Response time SLA measures elapsed time from case creation to first technician acknowledgment or on-site arrival
- Resolution time SLA measures elapsed time from case creation to confirmed problem resolution and customer acceptance
- Availability SLA measures equipment uptime percentage over a contract period, typically 99.5% or 99.9% thresholds
- Business hours vs. calendar hours clock rules stored in the ERP contract determine which hours count toward SLA measurement
- Clock pause conditions (awaiting customer response, parts on order) suspend SLA timers when the delay is outside your control
Real-Time SLA Monitoring and Escalation
SLA tracking is only useful if it drives action before a breach occurs. Real-time monitoring dashboards with countdown timers show work orders approaching SLA thresholds. Automated escalation rules notify managers, reassign work orders to available technicians, or authorize overtime when SLA breach is imminent.
The field service platform provides the operational data while the ERP provides the contractual terms that define the thresholds.
- SLA countdown timers on work order list views show remaining time before response and resolution deadlines from ERP contract terms
- Automated escalation rules trigger email and mobile notifications to service managers when work orders reach 75% of SLA window
- Priority re-sequencing in the scheduling engine promotes at-risk work orders above lower-priority jobs automatically
- Emergency dispatch authorization workflows unlock overtime or premium parts shipping when SLA breach is imminent
- Live SLA compliance dashboard displays current period performance by customer, contract tier, and geographic region
SLA Penalty Calculation and Financial Impact
SLA breaches carry financial consequences defined in the service contract: service credits, penalty payments, or contract termination triggers. The ERP must calculate penalty amounts based on breach data from the field service platform, apply credits to future invoices, and report the financial impact of SLA non-compliance. This closed-loop process ensures accountability and drives continuous improvement.
- Breach data from the field service platform feeds ERP penalty calculation engine with breach type, duration, and affected contract line
- Service credit calculation applies contractual formulas: percentage of monthly service fee per hours of SLA breach beyond threshold
- Credit memo generation in the ERP issues service credits on the next billing cycle for confirmed SLA breaches
- Cumulative breach tracking in the ERP monitors whether aggregate SLA failures trigger contract termination clauses
- SLA performance reporting combines field service response data with ERP financial impact for executive review and customer business reviews
