For simplicity sake, I have a one task project (General Meetings) that has a
10 day duration and two resources assigned (Tim and Joe). Tim and Joe are
allocated to spend 10% of their time in these meetings. Now this task has a
fixed duration, and it is NOT effort driven. So, each are "estimated" to
spend 8 hours in meetings over the 10 day duration of this project.
Tim attends 8 hours of meetings in 3 days, and Joe only spends 4 hours in
these meetings. Well, in day 4, Tim gets pulled into another two hour
meeting and adds this additional work to the project schedule. When he does,
Project comes back with an error "The resource is assigned outside the
original dates for task General Meetings). The duration of this
fixed-duration task will change to accomodate the resource assignment".
Well...because of this extra 2 hours that Tim is putting into this task, the
fixed duration I am locked into has "creeped" out 6 days!! This is just for
a one line project, so imagine what happens when I have a 1 year project
where all of my dependencies are set and feed off this task. My team has
projects that are creeping out YEARS because of this issue. What can we do
to prevent this schedule creep? Fixed duration apparently isn't the
solution. Constraint dates on tasks don't help either. We're trying to do a
better job in "estimating" task durations, but we all know that estimates are
inded estimates and change throughout the life cycle of a project.
Any thoughts?
Thanks!
