Simulation is visual and animated, allowing you to easily see what’s happening in a process as time progresses. It’s also interactive, so you can quickly adapt it in any way that you might consider changing the real process. As simulation can run through time much quicker than real life, you can simulate days, weeks or years of a process in seconds. This enables you to evaluate the long-term consequences of any changes and decisions you make. Simulation allows you to compare different configurations under the exact same circumstances. By testing different ideas, you can choose the approach that will provide the best performance for key metrics in your process. As a general rule, systems that involve a process flow with events can be simulated – so any process you can draw a flowchart of, you can simulate.The processes you'll gain most benefit from simulating are those that involve change over time, variability and randomness.
