Using Risk+ with MSP 2007
in [Project]

From: AnthemAZ on 9 Mar 2010 18:55 Tom Mc Check your file(s) for any custom fields with a formula. Remove them and you should see an improvement in perf. This will slow R+ significantly when running simulations.

From: Tom Mc on 10 Mar 2010 10:41 Thanks for a good suggestion. However, it didn't seem to make a difference when I disabled all the custom field formulas. It still took about 20 minutes for 1000 samples of a small file (only 153 tasks). "AnthemAZ" wrote: > Tom Mc > > Check your file(s) for any custom fields with a formula.

From: AnthemAZ on 11 Mar 2010 13:16 Tom Mc Can you share your file? I'd like to look deeper for you as I've used R+ for many years and there are some tests I can run to isolate the performance. I'm using MSP 03. If available, sent to wjordan(a)gdc4s.com "Tom Mc" wrote: > Thanks for a good suggestion.

From: Tom Mc on 12 Mar 2010 14:06 I tried a test as follows: I created a brand new file from scratch. Added 200 tasks - each of 20 days duration. Linked them all as one long sequence. Added basic risk loading - i.e., "initialized most likely", then "quick setup". I set the calc method to "manual". Thus, I now have a very small and simplistic file (no formulas, no custom fields, no baselines, etc., etc.). It STILL took 20 minutes for 1000 samples. BTW... I spoke to Risk+ tech spt. They were unable to give me any worthwhile advice - except to "talk to Microsoft". I really don't want to pay money to get an answer. Thoughts? "AnthemAZ" wrote: > Tom Mc > > Can you share your file?

From: Jon M. Kelley Jon M. on 18 Mar 2010 10:31 We had been warned by our in house testers that Ms Project 2007 and Risk+ didn't appear to be completely compatible (extended run times, random errors, program hanging forever). When our corporation moved to office 2007, a small group of schedulers and engineers kept Ms Project 2003 instead of moving to 2007. On a monthly basis, we run Risk+ simulations on relatively large schedules (7,000 to 10,000 tasks), with 2,000 to 4,000 iterations. These runs take 2 to 8 hours on a multiprocessor HP engineering workstation, and are consistent enough that the time variations between runs of a given schedule is less than five percent, depending primarily on what else is running during the Risk+ simulation. Our simulation runs are primarily done to generate S-Curves & completion confidence intervals for particular tasks. Things that we've found that cause a large jump in run time is to include “Duration Analysis”, Cost Analysis”, “Critical Path Analysis”, and “Sensitivity Analysis”. My own history with Risk+ started before Deltek acquired the product from CS Solutions. I tried working with the CS Solutions programming team assigned to support Risk+. What I was eventually told by the team lead was that when CS Solutions acquired the product from ProjectGear Inc, they got the source code, with little knowledge of how or why it worked, and as long as the product sold, weren't willing to even work on known bugs. When Deltek acquired the product, we still had maintenance contracts, and tried again to work with the Deltek developers, with the same result – about the only change they were willing to make was to replace “CS Solutions” name in the product with “Deltek Systems”. The current drive at our corporate level is to move to Oracle Primavera, but with our customers are still requesting Ms Project 2003 schedules with Risk+ analysis, we have to convince our customers that Oracle will provide better long term support than Deltek has provided.
