Kristen's Cookies Case Summary

1. How long will it take to fill a rush order?
Our group has calculated (see Appendix Figure 1) that it will take 24 minutes to fill a rush order if it is the first order placed in the night. This assumes that the oven is already preheated and the mixer bowl and beaters are clean (as sanitary requirements would demand). However, all subsequent orders will require 26 minutes because of the two minutes to wash the bowl and beaters.
2. How many orders can be filled in a night assuming you are open 4 hours?
16 min + 10x = 240 min
10x = 224
x = 22 orders
If a all customers order 3 dozen (the maximum the bowl can handle) and they are all the same cookie, such as a sugar cookie, …show more content…
then on a time chart it takes 44 minutes from the time Kristen's open until the first order of three dozens cookies is filled. However, the second batch of three dozens can start at the 29th minute with washing the mixer until all tasks are completed so that by the 37th minute when the last dozen of the first order is finished the first dozen of the second order can be put into the oven for baking. From then on every 10 minutes an a batch will be baked. So that by the end of the night 22 orders can be baked, leaving time for cleanup. Notice after the first order where mixing bowls aren't required to be washed there is a pattern that develops for all subsequent orders. It is interesting to note that regardless if the orders are for 3 dozens of the same cookie or for a different type each order, the maximum that can be produced is 22 dozen.
3. How much of your time and your roommate time will be required?
It will take Kristen a total of 8 minutes per batch. It will take your roommate a total of 4 minutes per batch. Although, the case states the time to put to cookies in the oven is negligible, it is worth noting that total time for the room make may average a bit more than 4 minutes do this additional task. There will be 9 minutes of downtime in which the cookies are baking. This is all assuming the orders are for one dozen cookies. Over a course of a 4 hour period Kristen would be working 2 hours and 56 minute, while her roommate would be working 1 hour and 28 minutes.

|Roommate’s Tasks | |
|Prepare Oven |1 minute |

|Collect Money |1 minute |

Should discounts be given?
No discounts should be given. Regardless if the orders are for 3 dozens of the same cookie or for a different type each order, the maximum that can be produced is 22 dozen. However, is would be worth considering giving a discount to returning customers to keep the orders coming in which would also encourage return buyers. Please view these calculations in Figure 2 of the appendix
5. How many electric mixers and baking trays will be needed?
Our group was unanimous in the decision that adding an electric mixer will not improve output. The minimum number of baking sheets needed is 2; one in the oven and one to be placed in the oven. Additional baking trays would not improve output.

production?
Some improvements could be centered on making the dough ahead of time, or possible looking at purchasing a mix ahead of time.
We also calculated the expense of an additional oven and found that it can be justified (depending on the cost and the cash flow of the operation). The spreadsheet was too large to embed within this paper, however. The oven would have to be electric and not violate either city code or the apartment agreement. Assuming we don't purchase a used oven, one available at a garage sale or one purchased off of Craig's list, the cheapest electric oven at Lowe's was $300.00.
If we sell cookies for $5.00 a dozen, our net profit would be $4.30 per dozen. Thus, if we do the maximum order then the total revenue per four hours would be $110 with a net profit of $94.60 per evening. Since electricity is paid for, then the only cost would be $300.00 for the cost of the stove. Depending on number of orders received in the night, a purchase of a new stove could be warranted. Another consideration is to see if it was possible to “lease oven time” from a
neighbor.

Timeline of the 1st 49 minutes of the a baking night if the first order request is for the 3 dozen cookies (the maximum the mixer will hold). Notice after the first batch is in the oven is taken out to cool (17 minute mark) then, and only then, can the next batch be placed in the oven (17 minutes and every 10 minutes from then on).
Timeline of the 1st 50 minutes of the a baking night if the every order is requesting a different cookie which would require the mixer and bowl to be cleaned. Notice after the first batch is in the oven is taken out to cool (17 minute mark) then, and only then, can the next batch be placed in the oven (17 minutes and every 10 minutes from then on). This shows there is no time-saving in doing 3 dozen cookies or 1 dozen because of the bottleneck---the oven.
