Adding Additional Work to MS Project 2003
in [Project]
|
From: Al Bayer on 19 May 2010 09:45 I would like to do some what-if analysis on my project schedule and am not sure how I can easily add say 30% additional work across the board on my project to show some best and worse case scenarios. Would I have to use a PERT chart to do this sort of filter?
From: JulieS on 19 May 2010 09:56 Hello Al, PERT analysis in project 2003 is based upon duration, not work. While work and duration are related through assignments, if you have changed the task type from the default of fixed units, adjusting duration will not necessarily change work. The PERT analysis tools are available on the PERT Analysis toolbar. Using the optimistic, pessimistic, and most likely durations and then calculating the PERT should give you a starting point. I hope this helps. Let us know how you get along.

There's a couple ways to do it. The easiest way would be to just save a different version of your file. I'd then set the tasks to Fixed Units (assuming you have resources assigned already), copy the Work column into Excel, add 30%, then paste it back into the file, and observe the havoc it wreaks on your durations - or some variation thereof. PERT works for Duration estimates, but will be hard to get to work with Work estimates. Or you could go out and get a third part Risk Management tool - but that may be overkill. - Andrew Lavinsky Blog: http://blogs.catapultsystems.com/epm > I would like to do some what-if analysis on my project schedule and am > not sure how I can easily add say 30% additional work across the board > on my project to show some best and worse case scenarios.
