When a target group is launched at Syno source, the cost per interview (CPI) is repriced according to the actual length of interview (LOI) and the actual incidence rate (IR), based on the rate cards of each panel.
For example, the expected LOI was entered 3 min., and the expected IR was entered 100%. If during the fieldwork either LOI or IR (or both) changes so that the CPI gets higher, the target group will be halted. The user then is informed that the target group has been repriced and the new CPI is provided:
- If the client declines, then the new CPI is applied for the already collected completes, but the target group will not be sampled anymore.
- If the client accepts, then the new CPI is applied for the already collected completes, and the target group will continue being sample with the new CPI.
In order to avoid the target group being halted frequently, the user can enter a maximum CPI that they can pay once the target group is launched. This way the target group will not be halted even if the CPI increases compared to the original CPI, but until it will not hit the maximum CPI. If the maximum CPI is reached, then the target group will be halted as described above. The maximum CPI can be set when the CPI type is Auto (not Fixed).
