FTE, or Full-Time Equivalent, is a unit that measures employee workload. In PMI, FTEs can be displayed in the scheduling module instead of hours, providing a more intuitive understanding of staffing levels. The number of hours a FTE works per day can be set in the cockpit settings. The Staffing guide in PMI uses the determined FTE to suggest daily hours in 0.5 FTE increments, ensuring practical scheduling.
