When you have sent the questionnaires to all of the people involved in the appraisal, you can monitor the progress of feedback and (if required) chase people who have forgotten to respond.

The chasing process can be fully automated to send a reminder a few days before the ideal due date and then again when the due date passes.

Further reminders to complete the questionnaires can be sent as often as required to ensure sufficient feedback is received to create a valid report.
