On a schedule, linking tasks in the order you have arranged them in using FS (Finish to Start) dependencies by clicking the Link in Sequence button. For tasks that do not fall in that order, you can use custom linking to adjust. Available dependency types are FS (Finish to Start – after the first task finishes, the second task starts), SS (Start to Start – the start of the first task triggers the start of the second task) and FF (Finish to Finish – the second task continues only as long as the first task is in progress).
