The oven

question 14

(For this question, please consider the information described in theinitialprocess flow diagram. That is, please ignore the experience gained by Mary 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 process from 9 minutes to 4 minutes. Considering only this change, what is the bottleneck now?

Mary/Bowl

The oven

John

There is not bottleneck

or questions 7 to 15 consider the following 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 ell 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 roduction 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 tage, and the duration of each activity. This process makes 12 cookies at a time, which is given by the baking capacity of the oven. or 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 rom the bottleneck analysis
