Three hundred people working in 40 state offices process X120 forms.

a. To evaluate a proposed change in the X120 form, would you randomly assign offices or individuals? That is, if offices are assigned, 15 offices would use the form with the proposed change, and 15 offices would continue to use the existing form. If individuals are assigned, roughly 50 percent of the individuals in the office would use the form with the proposed change, and 50 percent would continue with the existing form.

b. Would you allow subjects to volunteer to test the new X120 form? Justify your answer.

c. Would you test the new X120 form in the three slowest offices and evaluate the change in productivity? Justify your answer.
