Hello
Each project manager prefers to see parallel tasks instead of long chains of FS linked tasks.
Especially when tasks are not very small deliverables, there is always the choice to choose SS+Lag or FF instead of FS relationship.
Example: Instead of waiting for AFC foundation drawing, Structural design can start almost a week after start of foundation design (when calculations are available).
I always wonder which link is the best for this purpose (SS+Lag or FF).

What is your experience?


Have fun

    My preference would be FF, as the start of the successor is then dicated by the progress of the predecessor.

    Hey Steven,
    Thanks for your response.
    In FF case, the successor task will be planned to start latest possible. Task A= 10 days, Task B=2 days. Defining B as successor to A with FF relationship, will plan B to start on day 8, which is not very favorable.
    Am I right?

    It should start on day 9 (i.e a 2 day task will occupy days 9&10 to finish coincident with a 10 day activity.

    What makes you think that this would be unfavourable ?
