Perhaps the corollary to taking a risk for the fun and/or the learning is that success is often met with anger and suspicion. Human nature lives on both sides of the coin.
The team that took the big risk yesterday reaped a big win. The first email from a student on another team arrived 30 minutes after the simulation results were posted; that email simply requested a meeting about "some simulation questions." The next email arrived before noon and contained accusations of "unethical practices." The correspondents are on the same team and they have concerns...about their grade, mostly, and any negative impact as a result of a competing team's success.
The phrase that concerns me the most is this one: "this jump in success is not realistic in a simulation (or the real business environment)." Oh, but the success is realistic. A team or a company can take an enormous risk, combining some hard-won knowledge, a bit of courage, and what can only be called luck. There will be criticism from stockholders, customers, and employees when it goes badly. There will be accusations from competitors when it goes well.
It will be interesting to see which students analyze this success in order to learn and emulate...and which respond with anger and suspicion. Student frustration yields another teaching opportunity, just as soon as cooler heads prevail.
