How can I set up buffer time in case of task dependency?
Lead/lag can be used if there are dependencies set between the tasks. The tasks can have predecessors of 2 types: FS ( Finish to Start ) and SS ( Start to Start ) These dependencies decide the Start date of a task, i.e. if task A is FS dependent on task B, it means that the task A can start only after task B is completed. In this case even after setting the dependency, if you want a change of the dates, then you can make use of the Lead/Lag options. For example, consider task 5 is FS dependent on task 4 . The Finish date of task 4 is 19-01-2006 and hence the Start date of task 5 is 20-01-2006. This is how the dates due to dependencies are set. But due to some reason you do not want task 5 to start on 20-01-2006. In this case, you can set the dependency for task 5 as 4FS(3), which means that the task 5 will start on 23-01-2006 . Similarly lag can also be set for task 5 by having the dependency as 4FS(-3). In that case task 5 will start on 17-01-2006. Note that here 3 is taken as 3 days.
