Vacation Calibration is a setting in Chili Piper for Round Robin Queues. This setting can be found under Workspace Settings from the Left Sidebar Navigation:
To enable this setting navigate to Workspace Settings then Round Robin Settings
Chili Piper considers a vacation to be a full day event marked as busy on the user's calendar based on their working hours in Chili Piper.
For example, if these are my personal working hours:
Then having an all-day block or a busy block from 9:00am - 3:30pm on Friday or 8am - 5pm on Wednesday would be read by Chili Piper as a vacation day
By default, a full day block does not affect meeting distribution for Round Robin queues
Once checked, the assignee meeting count will be given "fake" meetings upon returning so that Chili Piper does not try to catch him up based on his meeting deficit. This means his Total Meetings will be the average of his teammates upon returning.
A queue has three assignees: Alina, Nicolas and Hugo. On June 4th Alina goes on vacation. At this point the meeting distribution is as follows:
Alina: 3 meetings
Nicolas: 3 meetings
Hugo: 3 meetings.
When Alina comes back from vacation Nicolas has 10 meetings and Hugo has 9.
Alina will be normalized at 9.5 meetings, the average between his teammates and an automatic calibration of 6.5 meetings will be applied. Chili Piper will suggest Hugo since he is at 9.
When Vacation Calibration is enabled for a rep and their calendar has all-day block, OFF will appear next to the rep's name in the Round Robin History as shown here to indicate they are currently not being considered in the Round Robin:
And in Instant Booker:
You can adjust when vacation calibration kicks in and is disabled for a rep by adjusting the Booking Span in your Workspace Settings. Booking Span represents the number of days before a vacation that an Assignee is removed from Meeting Distribution and the number of days before an Assignee returns from vacation that they are reactivated for meeting distribution.
