State Automobile License Renewal Case
According the case: Kristen’s Cookie Company (A), we can draw the Flow Process Chart, which could visualize the process of making a dozen of cookies.
Q1.
As we can see from this Gantt chart 1.1, the Rush Order Time is 26 minutes for one dozen size order. Chart1.1 A One Dozen Size Order
The Gantt chart 1.2 clearly show the Rush Order Time is 36 minutes for two dozen size order.
Chart1.2 A Two Dozen Size Order

Q2.
One dozen size order: In this situation, the bottleneck is “setting up the oven and baking”, which takes 10 minutes to finish this process. So, the Cycle Time (CT) is 10 minutes. The Kristen’s cookie company can finish the first dozen after 26 minutes, then Kristen and her roommate can complete each order per 10 minutes. 4 hours=240 minutes. (240-26)/10=21.4, and 21.4+1=22.4.
According to the equations above, the company could fill 22 orders every night.
Two dozen size order: In this situation, the CT becomes 20 minutes. The company finished the first order after 36 minutes, then they could complete each order in every 10 minutes. 4 hours=240 minutes. (240-36)/20=10.2, and 10.2+1=11.2.
According to the equations above the company could fulfill 11 orders every night.
Three dozen size order: In this situation, the CT becomes 30 minutes. The company finished the first order after 46 minutes, then they could complete each order in every 30 minutes. (240-46)/30=6.5, and 6.5+1=7.5
According to the equations above the company could fulfill 7 orders every night.
Because they have 14 minutes left after finishing all 7 orders of three dozen size, they could make a dozen cookie for a one dozen size order.
