I was going through some papers today and, finding this, thought some here might find this useful. In the class I taught, students would first develop business ideas to the point where the business models had internal validity. But just because the model made sense doesn't mean it was likely to generate significant returns.

In order to work through this situation with students and iterate the models, I put together a series of questions to find places where the model could be changed to improve returns. Because it's for young students, the concepts are rather simple, for example reducing costs by "Using volunteer labor" could take on more sophisticated forms like crowdsourcing, but that was outside the scope of my class.

Comments welcome and appreciated.
