Benchmarks
Service Level (e.g. 80/20)
The famous 80/20 (80% of calls answered within 20 seconds) is an inherited default with no research behind it, not a law. Read it as one point on a spectrum: tighten toward 90/10 for VIP, critical, or emergency lines, relax toward 70/30 for low-urgency queues, and set a band (roughly 78-85%) tuned to the abandonment rate you can actually live with rather than chasing a single number.

Benchmarks describe other teams, not yours. Read them as a sanity check on direction, not a target to hit — the right number depends on your channel mix, customers, and how you define the metric.
