Recently I’ve refurbished an old project of mine, the Call Center Simulator CCsim (https://apps.apple.com/de/app/ccsim/id1519438028?mt=12). It was a lot of fun to develop this heavy multithreading app. One main reason for me at the very beginning was to see how big the influence of the actual shape of distributions (e.g. for the call duration) besides the mean value is on the results. Now we do have this tool and we can play around a little bit.
