For questions 4, 5, and 6 assume that parallel processing can take place.

4. Since the cookie sheets can hold exactly 1 dozen cookies, BBCC will produce and sell cookies by the dozen. How much time will it take to fill an order of 2, 3, or 4 dozen cookies?

5. Assuming each order is for 2 dozen cookies, what is the production capacity in cookies per hour and takt time of this process?

6. What is the WIP inventory level if demand is from customers ordering 1 dozen at a time if the system consists of 2 ovens and Billy is working alone? (Assume that there is a backlog of orders so the bottleneck is always in the production process.)
