A made-to-order bakery makes filled cupcakes using a 4-step process:

Step 1. Mix and measure Step 2. Fill cupcake molds with batter Step 3. Bake cupcakes Step 4. Fill and frost cupcakes

Assume all machines are equally weighted and are not different.

1. Where is the bottleneck? Where is the bottleneck?

a. Step 1

b. Step 2

c. Step 3

d. Step 4

e. Cannot tell from the information provided

2. What is the capacity of this process?

a.

12 batches per hour

b.

7.5 batches per hour

c.

3.33 batches per hour

d.

5 batches per hour

e.10 batches per hour

F. 6 batches per hour

3. If customer demand is 6 batches per hour, what is the throughput (a.k.a. flow rate)?

	a.	10 batches per hour
	b.	7.5 batches per hour
	c.	6 batches per hour
	d.	3.33 batches per hour
	e.	12 batches per hour
	f.	5 batches per hour

4. If customer demand is 6 batches per hour, what is the capacity utilization for the bottleneck?

	a.	60%
	b.	50%
	c.	75%
	d.	80%
	e.	100%

5. Find the CWIP for the production line

Make sure you calculate around the SAME TIME UNIT. If your system WIP is already at or above the CWIP, adding more jobs into the system will NOT make the operational performances any better.

	a.	135
	b.	4.3
	c.	258
	d.	5.375
	e.	322.5
