The list of things we need to know in order to create a good simulation includes, the number of users, what they are doing, how often they are doing it, and when they are doing it. We also need to consider scenarios such as; beginning and end of shift activities, seasonal trends, special events, the ever present 2 am backup activity. Once we’ve collected all of this information and have scripted it into a load testing tool then we are ready to start the process finding our bottleneck.
