# Review Case Data Entry

After the Data Entry task is complete, the system assigns a Quality Control (QC) task to the appropriate workflow participants. The QC task is an important step in the Case Processing workflow to ensure the Case is complete and accurate, without any data entry errors or missing information. If configured, <a href="/en/gr/679956/">QC Checklists</a> can be generated to provide guidance during the QC process for a specific Case.
