Dr. Kim van Oorschot introduced a dynamic model to simulate Agile Software Development. This thesis study is aimed at applying the System Dynamics modeling technique to verify Oorschot’s simulation result to see if it corresponds well with what we can see happening in the real world. We found that the reported behaviors of several variables in Oorschot’s model do not actually reproduce the behavior of Agile software development in the real world. This research would help us build a more precise dynamic model to simulate Agile software development for further investigations.
