This solution maps Pega Platform automation shapes to their specific business requirements:

1. Send email: Used to generate and send automated correspondence (confirmations) to interested parties.
2. Change to a stage: When a case is rejected, the workflow must often revert to a previous phase (e.g., a "Correction" stage) to allow the employee to modify data. This shape transitions the case flow to a specific stage.
3. Push notification: Specifically designed to send alerts to mobile devices, matching the requirement for a "mobile notification."
4. Create PDF: This automation converts a section or view of the case data into a portable document format (PDF) and automatically attaches it to the case file, satisfying the requirement to attach a finalized report.
