Gantt: Multiple tasks as prerequisite for a milestone

Question

In my projects I have often the case that multiple independent tasks must be finished in order to finish a milestone. It would be nice to have this implemented.

Answer 1

It's already possible. Just add multiple statements

[Milestone] happens at [X]'s end

[Milestone] happens at [Y]'s end

in order to have the milestone at the end of whatever task ends last.

Comments

Correct, but only works if the milestone "is the last statement".

As soon as you add some dependency it is not recalculated again.

e.g. following will point the milestone to day "5", since this was the time when the "Milestone" was set.

[X] lasts 2 days

[Y] lasts 5 days

[Milestone] happens at [Y]'s end

[Milestone] happens at [X]'s end

[X] -> [Y]

Led me into problems, since I tried a generic approach (assign a task to a milestone in a procedure and later on do the dependencies)

Hello  all,

In fact the general rule for Gantt diagram is:

1. Create task or milestone
2. Put all dependency
3. and only after: put other task or milestone with constraint of the previous tasks or milestones...

If that can help,
