During this chapter, Mr. Thompkins had the opportunity to meet an interesting character, Dr. Abdul Jamid, for his surprise, Abdul is recommended by his old boss Jay, and finally, he had the opportunity to talk with Dr. Abdul.

Abdul reached Mr. Thompkins with the purpose of teaching him an important tool for Project Management. This tool is called Modeling and Simulation.
In the book this works by using a software called ithink but of course, this software is not necessary for the concept.
The concept of Modeling and Simulation follows a pipeline, the first thing you have to do is to Model your hunches about the process that gets work done, then you use the models to communicate and refine your thinking about how the process works. Once you have the model you simulate the results and finally you tune the model against the actual results.

This concept is important since it can be applied to lots of things, not just Project Management, in fact Machine Learning often uses this approach.
