Service level is the share of incoming calls answered within a predefined time. A common target is written as 80/20, meaning 80 percent of calls should be answered within 20 seconds. The metric shows how available your team is.
How the metric works
- You set a target answer time, for example 20 seconds.
- The system measures the share of calls answered within that time.
- Results are tracked over days, weeks and by group.
Why it matters
- It reflects the customer experience of availability better than an average answer time.
- It helps you staff correctly at peak times.
- It is a clear, comparable target for the team.
Service level connects to call queues and distribution via ACD. Note that service level is a metric, while an SLA is an agreement that often contains a target service level.
