Order the steps in the process for finding the order quantity that maximizes expected profit

1. Evaluate the critical ratio 2. Find the z value that corresponds to the critical ratio 3. Use the z value to calculate the optimal order quantity for the true demand distribution

To compute expected sales for a given order quantity you need to know or compute which of the following:

1. expected inventory 2. the order quantity
