If you select Activate the survey now when going live, the survey will automatically end 30 days after the start date.
If you define the start and end dates and click on Activate the survey, there are no system specifications for either date. However, it is not advisable to let the survey run for too long because you can only analyse the results once the survey has ended and then gain an insight into the answers provided by the questionnaires.
Please give participants enough time to complete a survey, particularly if some participants have to fill out a lot of questionnaires. It is also advisable to take into account holiday periods and project deadlines when participants will have less time to spend on a 360-degree feedback.
Once every participant has answered all the questions, the survey will end automatically, even before the end date that was defined.
