Technical Corner – What’s the Use of Sensitivity Analysis?

After describing recently the rather sophisticated sensitivity analysis features of Full Monte, I was asked what use the results were.  Knowing which tasks are likely to affect ones project completion date — or maybe the date of an important milestone — is clearly of interest, but what can you actually do with this information?  As …

I have been writing project scheduling code for over 30 years, including a number of risk analysis and resource leveling algorithms.  But I have never done them together, and two recent LinkedIn discussions have caused me to re-examine the reasons. There is of course a practical reason.  Resource leveling typically takes far longer than unconstrained …

Why Things Don’t Add Up

Last time we learned about continuous distributions and how they are described by the frequency function. I also promised to save us from the infinitesimal probabilities represented in the frequency function. The answer is the Cumulative Distribution Function (CDF), which is merely the area under the frequency function curve to the left of a given …

Resource Scheduling

Over the years, I have written a number of schedule risk analysis programs, the latest being Full Monte for Microsoft Project. From time to time, I have been asked why they never take resource scheduling into account. There are actually two problems. The more fundamental one is that there is a mismatch between the assumptions …
