A simulation model goes one step further than static data analysis tools, because it can show how the process dynamically changes over time. Process simulation is the act of reproducing the behavior of a process, using a model that describes each step. Once the process is modeled, the analyst can make changes in the model to measure the impact on certain metrics, such as response time, waiting lines, resource utilization, and the like.
