Task Links

All projects require that the WBS tasks be performed in a certain order. These relationships are defined in RiskyProject using the four linking buttons located on the standard toolbar.

The four types of task dependencies are show in the following figure:

If you want next task to be predecessor of previous task, for example task 5 to be a predecessor of task 3, you will have to use Predecessors tab in Task Information dialog box . You should also use Predecessors tab if you want to define lag time greater than zero.

Remember the following rules:

1. You cannot link summary task to one of its subtasks



2. The predecessors of a summary task must have a finish-start or start-start dependency.



3. You cannot create circular relationships.



4. The connecting line between successors and predecessors will be red if there is a scheduling conflict:
