Suppose Pharma Company Z created a new drug to combat osteoporosis (bone loss) in senior citizens. A special training program was designed for experienced pharmaceutical sales representatives ("PSR") to learn how to best market this product. The PSR were taught to educate physicians about the unique benefits of this drug. If you designed the training program, how would you evaluate its effectiveness? Would you factor in the lag period between the training and the length of time it takes physicians to get comfortable writing prescriptions? What if the insurance companies refused to reimburse patients for the full cost of the drug? How would this impact the evaluation of the training program
