The program enables users to switch between profiles to view the schedule of any staff member, it is also possible to view multiple profiles simultaneously or open the schedules of several specialists at the same time. Once you've specified a required sequence, it is automatically visualized across a horizontal timeline. Task dependency is shown via connector lines. This software tool can display completion percentage for each individual task. An overall progress indication option is also available.
