A dependency chain is a relationship between multiple tasks or milestones. The dependency chain is created relative to the task or milestone positions in the work breakdown structure in the Gantt view. The type of dependency created is a finish-start dependency with zero lag. The next task or milestone in the chain relies on the completion of the previous task before it can start.
Example of finish-start dependency chain
Suppose, you have three tasks: Task 1, Task 2, and Task 3. Task 3 can start after completing Task 2, and Task 2 only after completing Task 1. You can create a dependency chain from Task 1 to Task 2, and from Task 2 to Task 3.
