{{main|Sales process engineering}}
Simulations are useful in modeling the flow of transactions through business processes, such as in the field of [[sales process engineering]], to study and improve the flow of customer orders through various stages of completion (say, from an initial proposal for providing goods/services through order acceptance and installation). Such simulations can help predict the impact of how improvements in methods might impact variability, cost, labor time, and the number of transactions at various stages in the process. A full-featured computerized process simulator can be used to depict such models, as can simpler educational demonstrations using spreadsheet software, pennies being transferred between cups based on the roll of a die, or dipping into a tub of colored beads with a scoop.<ref name="Selden 1997">{{cite book|title=Sales Process Engineering: A Personal Workshop|author = Paul H.
