Finsh No Later Than vs. Must Finish On

[Bethany Schoenick, PMP]

Hi,

According to my bible, the following definitions apply

Finish No Later Than - A constraint that sets the completion of a task to
fall no later than a specific date.

Must Finish On - A constraing that forces a task to finish on a specific
date.

My questions than is - what's the difference between the two? I don't see it
but there must be one...

thanks much,
bethany

FNL allows the task to be completed before the constraint date, but not
after. MFO means it must finish on that date.
For example, if I shipping lettuce to a hotel for them to use for a
particular event, they probably don't want me to ship the lettuce a
week early, even if I could. The lettuce must ship on a certain date to
arrive on a certain date and no earlier. I'd use the MFO constraint on
preparing the lettuce for shipping.
OTH, the glassware can ship as early as possible, as long as they have
some place to store it. No problem if it arrives a week early. Just
don't want it to arrive a day late. FNL constraint on getting the
glasses ready to ship.
