Review what the groupings tell you, referring as well to the Process Flow Diagrams from Exercise 2. Keep in mind that it is not necessary to have exactly the same family value to be included or excluded from a product family. Similar values indicate that the process flow for those products is also similar, increasing the likelihood that they will work well together on a Mixed Model line. Finally, remember that several products might share Process Commonality, but have highly variable labor content or parts requirements. Set this aside – you will use in in Exercise 9.
