More Shocking Revelations From Dr. Gui on GPM Simulations: Build a better model, get a better simulation.

Some might say, if it’s not broken, don’t fix it, those are the same folks who fail to innovate, time and time again. In the case of CPM’s current model, it’s surely broken. Every time a CPM monte carlo is executed the process is as follows:

The user selects a duration from the range for each activity then the model runs the forward and backward pass. This yields a single iteration. It is run as many times as required in order to achieve convergence. Read More

Another Amazing Discovery by Dr. Gui on Risk Analysis Current Practice

Safe Float – what is it and how does it impact the risk analysis process?

Let’s just delve right in to this. In the model below we can see that there are three activities with finish to start relationships. The duration for each activity is 30 days. There is a 10 day gap between each activity (this is a feature of GPM based on planned dates) The float value is displayed beneath each activity with 54 for Activity (A). Read More
