Imagine designing a conjoint for your b-school’s café. In particular, you’re in charge of the daily pizza orders.

Wheat crust vs. white, thick vs. thin, plain cheese vs. sausage vs. sausage and green pepper vs. vegetarian (you get the picture). Design a conjoint that would result in identifying 2 or 3 popular slices that your café managers could order every morning. The student body knows you’re responsible—how do you make most of them happy?
