1. What is the bottleneck of the process? 2. What is the cycle time of the process?

9 min/dozen

10 min/dozen

4 min/dozen

8 min/dozen

3. After several days of practice, Mary becomes more experienced. Now the Wash and Mixing time only takes 4 minutes. What is the bottleneck now?

The oven

The bowl

Mary

John

4. (For this question, please consider the information described in the initial process flow diagram. That is, please ignore the experience gained by Mary as described in previous questions.)

Mary and John decided to buy a second oven with the same specifications as the one that they have right now. Considering only this change, what is the bottleneck now?

Mary and John decided to buy a second oven with the same specifications as the one that they have right now. Considering only this change, what is the flow time of the process?

6. (For this question, please consider the information described in the initial process flow diagram. That is, please ignore the experience gained by Mary and the assumption about the purchase of a second oven as described in previous questions.)

Assume that the current oven breaks. Mary and John decide to buy a new and upgraded oven to replace the broken one. With the upgraded oven, they can speed up the baking from 9 minutes to 4 minutes. Considering only this change, what is the flow time of the process?

Mary and John are two hard-working students who have decided to start a new business in their neighborhood. They want to sell fresh and customized cookies! They sell the product to their customers in boxes of 12 cookies. Once they receive the order in their computer, they can start mixing and baking the cookies. The whole production process is simple, and it is summarized in the figure below. The figure shows the different stages of the process, the different resources needed on each stage, and the duration of each activity. This process makes 12 cookies at a time, which is given by the baking capacity of the oven. For this question, assume that you have enough trays and therefore they are not influencing the overall capacity of the process. That is, you can exclude the trays from the bottleneck analysis.
