Partial predecessor

[Jpstewar]

Scenario: Information from task A is needed for task B, which is a meeting
(or milestone) on the project plan - think of it as task 3, the MRC
pre-meeting. Task A does NOT have to be finished by the time of the meeting,
but some information is needed. We are calling A a predecessor to B, but
maybe that is not correct. We just need information from A so let's say A
needs to be 25% complete. Is there a way of capturing that?

Link task A and task B with the default Finish-to-Start dependency. In the
Gantt Chart, double-click the link line between task A and task B (it's the
easiest to double-click on the arrow head at the end of the link line). In
the Task Dependency dialog, select the Start-to-Start dependency and then
enter 25% in the Lag field. Alternately, leave the Finish-to-Start
dependency selected and enter -75% in the Lag field. In either situation,
click the OK button and you have modeled the dependency relationship you
seek. Hope this helps.

I tried these and it looks like they both have the same end result. B starts
25% of the way into A. So it seems moot as to whether you use F to S or S to
S. Either way, same end result, yes?

Yup, both end up with pretty much the same result. I personally like the
first approach. I know that others like the latter approach. Choose one
and go for it! Hope this helps.
