Task dependency

[Klaus Hoffman]

Is there a way to schedule a task so it starts at the
earliest starting timepoint of two (or more) other tasks?

Thanks in advance,

Klaus

What do you mean? Are you saying that I have two tasks, one taking 2 days
and another taking 4, and linked to both of them is a third task, then you
want the third task to start when the 2 day task finishes instead of waiting
until the 4 day task is done? If that's the case, the third task is not
really a successor of the 4 day task and you should remove the dependency
link. I'm trying to imagine a real world situation that would have a task
dependent on two tasks and starting when the first of the two predecessors
finishes and can't come up with one. Could you provide an example?

Klas & Steve,
Does Klas perhaps simply want to use a Start-to-Start predecessor
relationship of the third task with the others?

Adjustment for task relationship
Finish to Start (FS)- The finish date of the predecessor task determines the
start date of the successor
Start to Start (SS) - The start date of the predecessor task determines the
start date of the successor task
Finish to Finish(FF) - The finish date of the predecessor task determines
the finish date of the successor task
Start to finish (SF) - The start date of the predecessor task determines the
finish date of the successor task
Those are the basic task relationship. I think the default is set to FS or
end to start. However you may need to alter this relationship. Some tasks
can be run in parallel without wait until one or other tasks are completed.

Hi,

The answezr is yes- there is, but I do not know whether you will like the
answer.
Make these 3 tasks subtasks of one summary.
The summary task will now start with the earliest of the three tasks.

Not exactly - suppose I have two tasks & the initial
planning is: one starting April 1, the other one April 3.
I now have a third task, that starts whatever is the
earliest starting date of the two other tasks. In the
initial planning this would be April 1, but think of a
project with many parallel tasks (>20), quite frequent
changes of starting dates, and very dense time-intervals
between the different tasks.

What I want to avoid is the reprogramming of the task-
dependencies, since my real-world example has many (really
a lot!) parallel tasks; and one task starting whenever one
of the parallel tasks starts. As a simplification think of
a scenario "first customer in" triggers "publish success
story in the internet" - but on a very time-compressed
schedule, so you do not want to fiddle around with
updating your task-dependencies....

Again my question: any idea how you can handle this (I
think this cannot be covered by FF, FS, SF, SS
relationships)?

Thanks in advance,

Klaus

See my post.
Summary tasks do that.
The only alternative is a VBA macro
