I'm working on a large project file (~2200 lines - unfortunately can't reduce
this) and am having trouble getting a true representation of my critical
path. I'm noticing that many of the tasks on the critical path have very high
negative total slack values and also that many of these tasks have started
already. Is there a relationship between a task starting and negative total
slack? ie, Does a task's Actual Start create an inflexible constraint date
that somehow triggers negative total slack in some or all of its
dependencies? Does the negative total slack mean I need to start that many
days earlier for the task in order not to delay the project?
I'm not sure if there are any settings or constraints we've set throughout
the project which may be causing this high level of negative total slack. We
are reviewing dates and variances weekly and are understanding where we're
behind. But the critical path analysis is a stumbling block with these
negative values and how to make decisions from it - unsure of how serious
this is and how to explain it to mgt. Any action you might suggest would be
most helpful - thank you!
