SS Dependency

[Monica]

It's my understanding that if I type 172SS in the predecessor field for task
173, both 172 and 173 should have the same start time; but for some tasks,
I'm not finding this to be the case.

There aren't any constraints on the tasks. Anything else I could check to
fix the problem?

Hi Monica,

Welcome to this Microsoft Project newsgroup

The SS doesn't quite mean they'll always start together - it means that the
start time of the predecessor determines when the successor is *able* to
start. The start of 172 (after taking into account any lag or lead times)
thus defines the EARLIEST that 173 can start but there are any number of
factors that might drive 173 to start later than the link might dictate,
things like the required resource not being available at just that right
moment, for example.
