Simulation is the process of testing and analyzing a business process to evaluate how it works under various scenarios. In the Kuika Process Automation module, Simulation is a tool used in process design and helps to predict the performance of the process by observing the effect of certain variables. It allows us to analyze how different inputs or conditions affect the flow of the process, so it becomes possible to identify potential bottlenecks, areas for improvement and efficiency opportunities. Process testing allows for more informed decision-making and optimization of the process.
