I have a requirement as follows
There are two project activities. Activity 1 , Activity 2.
Activity 1 is most critical and hence all other activities are dependent on Activity 1.
Activity 2 should finish 7 days before Activity 1 starts.
How do I map this requirement in ARAS PM?

Hi Jayraj,
In the predecessors column you can put the task dependencies like Activity 2 is dependent on Activity 1.
Often this is just done by adding the task that precedes another task.
You can also add modifiers to this column. You can use the following modifiers to specify the relationship between the Activities.
SF - Start Finish - This Activity can only Start after the other Activity finishes
SS - Start Start - This Activity starts when the other Activity Starts
FS - Finish Start - This Activity will Finish when the other Activity starts
FF - Finish Finish - This Activity will Finish as the same time as the other Activity finishes.
You can also add Lead and Lag days to this modifier.
So you can say 3FS-7 which means this Activity will start when Activity 3 finishes with a Lead/Lag of -7 days. Or this activity will start 7 days before Activity 3 finishes.
Hope this helps,
Brian.
