Abstract
This paper describes an agent-based simulation model to analyze the characteristics of project management through the scale of a project (team size) and the communication efficiency among project members. Considering the communication efficiency is proportional with the project productivity, our simulation results suggest that 1) the larger, the scale of a project becomes, the less efficient the communication becomes, and 2) it is quite difficult to make the delivery period of a large scale project shorter in comparison with a small one.
