Once you create multiple items on the Gantt chart you can place one of four types of dependencies linking the activities together. The four types of dependencies include:
- Finish to Start- An Activity can not start until its predecessor ends, although it can start later.
- Start to Start- An activity can not start until its predecessor starts. although it can start later.
- Finish to Start- The activity cannot end before its predecessor ends, although it can end later.
- Start to Finish- The activity cannot end before its predecessor starts, although it can end later.
To place a dependency between items, begin by hovering over an activity in the Gantt window, a circle will appear at the beginning and at the end of the activity. Click and drag the circle of the desired logic and drag it to the start or end of the activity you wish to link.
If you wish to delete the dependency simply double click on the line connecting the two activities and confirm the deletion.
