Microsoft Project and the As Late As Possible (ALAP) Constraint

The default constraint in Microsoft Project is ASAP. This is the ideal for most forward scheduling situations. Here we look at the As Late As Possible (ALAP) Constraint http://ow.ly/XWd830aUwVd

MSP ALAP's consumption of ALL TOTAL SLACK makes it pretty useless for CPM-type forward scheduling in my view.  If you are scheduling just-in-time material delivery for an installation that has some slack (not the TS=0 case shown in the example), then the ALAP constraint will delay the installation.  This is probably not what you intend.

MSP ALAP might be useful in a critical chain methodology, but those who are not explicitly managing feeding/project buffers should beware.

Just an opinion....
