A brief summary of the project steps:
- User Interface: Developed an UiPath App for employees register their name, RSVP and meal preference.
- Data Logging: Responses are automatically stored in Data Services.
- Manager Review: Tasks are created in Action Center for managers to review and approve RSVPs.
- Catering Report: A final report for the catering team can be generated as needed. An additional option in Action Center allows manager to provide the catering team’s email, triggering an unattended automation to send the report directly.
