Top management of a large company has told you that they really would like to be able to determine what the impact of years of service at their company has on workers' productivity levels, and they would like to be able to predict potential productivity based upon years of service. The company has data on all of its employees and has been using a valid productivity measure that assesses each employee's productivity. You have told management that there is a possible way to do that and offered an explanation. What have you told them, and how does the analysis work?
