“We’re trying to understand the traffic patterns along this route to Half Dome.”, she answered. "Participants show their time cards to officials stationed at various waypoints along the way. The officials will mark your time of arrival at each waypoint. Would you like to participate?”
“Perhaps.”, I said. “This sounds like you’re collecting data for a simulation study. Is that true?”
“What simulation tool are you using?”, I asked.
“Umm….I think it’s called ExtendSim. Yeah. That’s it. It’s called ExtendSim.”
I smiled and said, “Well, in that case we’d be very happy to participate in your study.” ;-)
So the next time someone asks you, “Where is ExtendSim used?”, maybe the most appropriate response is, “Where is it not used?”
