The Work Analytics documentation now covers the full metric set for per-agent reporting, and the two guides that back the live agent and queue views have been published.
The agentAverageTimeToAnswer metric is now documented on the Work Analytics agent-activity endpoints. It is a timing metric, reported in seconds, and sits alongside the other agent timing metrics such as agentTotalTalkTime, averageTalkingInteractionsTime, averageOnHoldInteractionsTime, and averageWrapUpTime.
The Contact Center Analytics documentation set has been refreshed for the 2.14 release.
