Quota Control helps you limit the responses to your survey. Using Complex Quota Control you can set up quota based on responses to multiple questions and / or custom variables.

Go To:

• Login »  Surveys »  Integration »  Sample Management »  Quota Control

In general you should NOT change the structure of the questions (that the quota is based on) - after setting up quota-control. However, if you add options to the system AFTER setting up quota control, you need to update the quota percentages for the newly added option.

Fundamentally the Quota Control is predicated on the total number of "Completes" - so, in cases where a large number of users are coming to take the survey at the same time, and the quota for a cell has not been reached, the system will allow them to try and complete the survey.

In such cases, when you have a large concurrent userbase, the system has no way of determining if the users that have been allowed to take the survey will actually indeed complete the survey. So, the system WILL NOT throttle until the quota is reached. What this means is that you have the potential of multiple people - who at the time of the quota question - did not have the quota cell filled - may end up completing the survey - thereby having more than the total allocated quota.
