About

Shiftly was developed as a group project for the Software Engineering and Project Management course at TU Wien (Vienna University of Technology) during the summer semester of 2025.

Shiftly is a web-based application designed to simplify shift scheduling for large organizations. It efficiently assigns employees to shifts while ensuring that each shift meets its required staffing levels. If adequate staffing cannot be achieved, the system automatically notifies the responsible manager via email. Among its key features, Shiftly includes an intelligent shift generation algorithm that considers employee vacations and assigns substitute workers ("jumpers") where needed.

Shift Planning

• Each shift has a defined required headcount.
• Employees are automatically assigned using a rotation algorithm that ensures fair distribution of shifts.
• Approved vacation requests are taken into account during shift planning. * However, unplanned events like sudden resignations or sick leave are not considered.
• If staffing requirements are not met, available jumpers from an external pool are flexibly assigned to fill gaps.
• The jumper assignment algorithm respects individual availability and prevents multiple shift assignments on the same day.
