What do contact center metrics like SLA, AWT and occupancy mean?

  • Audience: Contact center
  • Plan: Contact Center Pro

Last updated

Contact center reports and supervisor dashboards use a lot of short labels. This page explains what each one measures, so you know what your numbers are telling you. Labels in your reports and dashboard may differ slightly, and not every view shows every metric.

This feature needs the Contact Center Pro plan. See plans and pricing

Service level

Service level, often shown as SLA, is the share of calls answered within a target number of seconds. Check your messaging settings for the default target. It's set for your account, and your admin can change it. Ask CallSprout support whether your voice queue reports use the same one.

There are two ways to work it out, and whoever set up your system picks one:

  • Standard. Calls answered within the target, divided by all answered calls.
  • Leaving out quick hang ups. Calls answered within the target, divided by all calls received minus the callers who hung up within a short abandon target. This keeps callers who left almost at once from pulling the number down.

The supervisor dashboard is an add-on. It can use the same setting as your reports or its own. If the dashboard and a report don't agree, ask your admin which formula each one uses. When there's nothing to measure yet, the dashboard may show N/A.

Calls and wait times

Call and wait time metrics
MetricWhat it means
Answered and unanswered percentThe share of queue calls that an agent picked up, and the share that weren't.
Abandoned callA caller hung up while waiting to be answered.
Exit with keyA caller pressed a key to leave the queue before being answered.
Timed outA caller reached the queue's time limit before an agent answered.
Waiting time (WT)Time from joining the queue until an agent's phone first rings.
AWTAverage waiting time: the average time callers wait.
MWTMaximum waiting time: the longest wait any caller had.
Speed to answerTime from the agent's phone ringing until the agent answers. Averaged, it's average speed of answer.
Entry positionWhere a caller was in line when they joined. A high average means callers often join a long line.
Repeated callersPeople who called two or more times in the period.

Agents

Agent metrics
MetricWhat it means
SessionThe time an agent was logged in.
PauseTime an agent was logged in but not taking calls.
Idle and busyIdle agents are logged in, not paused and free. Busy agents are on a call.
Talk timeTime spent on calls.
Activity time, or handling time (HT)Time from when a conversation was assigned until it was closed or transferred. For calls, this is talk time.
OccupancyThe share of an agent's working time spent on queue and campaign calls. It's that talk time divided by the session time minus pauses.
Missed callA queue call rang an agent who didn't answer. One call can be missed more than once.
Dumped callThe agent hung up while the short announcement before the caller was connected was still playing.

Chat, text and email

  • First response time. How long a customer waited for the first reply from an agent.
  • Resolution time. How long the conversation took to close.

Outbound campaigns

  • Contact rate. Leads reached, divided by leads dialed. Which outcomes count as reaching someone depends on how your admin set up the campaign's dispositions.
