One of the real problems with business education is the heavy use of prepackaged case studies. While they purport to hone critical thinking skills, they also impart false lessons. Future managers come to believe that the information in front of them is complete, reliable, and predictive. The only thing left to do is exercise some thinking and then make a decision.
In real life it will never be that simple. Numbers are shaky and dirty data is a persistent problem. In the beginning there won't be enough critical information on the matter at hand. At the same time , there will be a flood of trivial and irrelevant material that demands attention.
It is tempting to wait until more data and better data can be obtained. Unfortunately, time is often a critical competitive dimension.
