Kristen Cookie Company Essay

Yes. If Kristen and roommate can only do their own job, the max order(order by order) they can process is 8 orders a night. But if they can cross-training, would 1. Receive order print and reply Roommate 1 minute/order Mix ingredients Kristen 6 minutes /max 3trays Spooning cookies onto tray Kristen 2 minutes/tray Cookies in oven Roommate 10 minutes/tray Cool down cookies Roommate 5 minutes/tray Pack Roommate 2 minutes/tray Accept payment Roommate 1 minute/order 2.

(1) Spooning cookies onto tray Cookies in oven

(If receive a 2-dozens order) While Kristen is spooning cookies onto tray, the first tray she finished can send to roommate to put into oven.

At the mean time, Kristen can spoon the second tray. (2) (If receive a 2-dozens order) While cooling down the first tray of cookies, roommate can put second tray into oven. (3) (If receive a 2-dozens order) After the first tray cool down, can pack directly. At the same time, second tray of cookies should be in the oven.


According to the answer of 1st question shown. So, amount of time to process a dozen of cookies is 27minutes (1+6+2+10+5+2+1=27) 4.

(1) If Kristen proceed order by order, will be 8 orders of single dozen per night. 4 hours=240 minutes, 240/27=8.88 orders. (2) If Kristen and roommate can proceed different orders at the same time, that is 240minutes/45 minutes = 5.3

5.3x2orders =10.6, 10 orders

be able to process more orders. Example shown below for 4hours performance of Kristen and roommate As the chart shown above, 4 hours of cross-training process can almost complete single dozen orders.


If Kristen and roommate still process order by order(process one order at one time), buying another oven can only reduce the baking time for 2-dozens order, 2-dozens order(time spend) complete orders in 4 hours one oven 1 + 6 + 2 + 10 + 10 + 5 + 2 + 1 = 37mins 6 two ovens 1 + 6 + 2 + 2 + 10 + 5 + 2 + 2 + 1 = 31mins 7 That’s mean, add another oven can only increase one more 2-dozens order. Therefore, buying another oven is not a good decision.


Question 3 is design to work from order to order, that is, Kristen and roommate have to (1) do their own job, and (2) can only process one order at a time. However, in real life, people will try hard to combine orders to save the time of process.


Without labor cost, the ingredients’ cost and the package cost are total $0.70. Assume that Kristen and her roommate both receive $10/hour as salary, and receive 15 orders per night. The total cost will be $90.5 per night, and $6.00 per pack of cookie. One pack of fresh cookies (daily made) sold in grocery store is about $3.00-5.00. We can assume that Kristen Cookies Company set their price at $6.00 pack. (Kristen and roommate only earn $10/hour/person as salary) Even though, the cookie Kristen Cookie Company provides is the freshest and most convenience for students. It is very hard to have extra profit. The significant problem that Kristen Cookie Company has is that *The producing process is not efficient. Because they are offering a customization service. If they can limit their product line into fewer categories They can switch their delivery system from “projects ” to “job shop” .
