What is the Diamond Model?  Based on the Diamond Model, what four factors  determine a firm’s competitive edge?  Why? 

The other thing that was learned during this week was that of the Porter Diamond Model and the sort of premise here is to look at the way the firm might be operating in its home country and then seeing what sort of effective or viable strategies that it could enact in its quest to go global. The goal here according to the Diamond Model is to be able to look at what the different “factor” based conditions are but also taking that in depth look at the different types of the demand conditions that might also be found in the larger market.  In addition to that, it would also be important per the diamond model to assess the notion of the strategy that the firm has put in place to expand to different parts of the world.
