Predecessors and Lags


You define information about predecessors and lags in the Predecessor tab of Task Information dialog box.
You can use the Standard toolbar button to link tasks; however, this method of creating task dependencies has limitations:
•  You cannot link a task (from example Task #5) to a previous task (for example Task #3).
•  You cannot input lag, which is time delay between predecessor and successor. RiskyProject allows you to setup probabilistic lag with statistical distribution defined by low, base, high number.


•  Sometimes it is convenient to use predecessor tab instead of link toolbar buttons when task has multiple predecessor or if there is a big difference in task Ids between current task and predecessor. For example, it is not convenient to link task number 5 to task number 74 using toolbar buttons.
•  You may use Predecessor column within Gantt view to define or modify predecessors. Text: “1, 2+2 days” would mean than current task has two predecessors (Task 1 and Task 2 with lag 2 days).
