When you use Zendesk to support customers, a question that people commonly ask is:
“How long does it typically take for one of my agents to respond to a ticket after it’s first created?”
Zendesk Support records the time from when a ticket was created to the first public agent response. Both Insights and Zendesk Explore read this value and make it available in a metric named First Reply Time.
Use this article to understand how first reply time works, and how you can use it in your reports.
This article contains the following sections:
How first reply time is calculated
The Zendesk first reply time metric measures the time between ticket creation and the first public agent comment after that.
After the first public reply, Support stores the first reply time in calendar hours and calculates and stores the first reply time in business hours.
First reply time works the same regardless of the channel from which the ticket originates. For example:
A customer email creates a ticket. Timing starts when the ticket is created and ends at the first public agent comment.
An agent creates a ticket. Timing starts when the ticket is created and ends at the agent's next public comment.
An agent takes a phone call that creates a ticket and solves the ticket with no new comment. The customer later re-opens the ticket, and the agent then responds with a public comment, first reply time ends when that comment is posted.
Reporting first reply time
Use the following sections to understand how to use the Zendesk reporting tools to read first reply time information.
Reporting using the Reporting Overview
This is not available with accounts that only use Explore. For more information about built-in reports, see Using the Reporting Overview. These reports:
Display the first reply time metric directly from Zendesk Support
Display calendar hours only; business hours are not displayed
Displays average reply time for all tickets
Reporting using Explore and Insights
Both Explore and Insights read first reply time information from Support. The reports:
Read data from Support using the Zendesk API. They do not calculate calendar hours or business hours.
Display information on pre-built reports in calendar hours. However, metrics for business hours are available, and can be used in your own reports.
For help with metrics, see Insights metrics reference and Explore metrics and attributes for Zendesk Support.
Reporting using External analytic tools
If you are not using any of the Zendesk reporting methods, you can still read first reply time information using the Zendesk API. The first reply time information in calendar hours is stored together with the first reply time in business hours and clearly labelled. For details, see the API metrics documentation.
Zendesk SLAs and first reply time
Zendesk Service Level Agreements, or SLAs, are an agreed upon measure of the response and resolution times that your support team delivers to your customers. To determine these times, SLAs also use the first reply time. However, there are important differences in the way that these metrics work with SLAs:
If a ticket is created with a public comment from an agent, the SLA first reply time target is not run
If a ticket is created with a private comment, the SLA first reply time target will not start until the ticket gets a first public comment from an end-user
SLA first reply time targets are fulfilled when a ticket is solved, even if the ticket never had a public comment from an agent.
SLA targets can be run in calendar or business hours, but not both.
Business hour SLA targets pause outside business hours, then restart when business hours begin.
