How do I make a start to start relationship between tasks?
To make a Start-to-Start relationship between tasks, you need to establish a Start to Start dependency in the Predecessors column or in Task Information dialog under the Predecessors tab. For example, you have task ID 1 and task ID 2 and you want to establish a Start-to-Start dependency. In task ID 2 on Predecessors columns write 1SS. Note: On Mac and iPad devices, you can also set task dependencies by typing the value in the Successors column.
