Assume you plan to make boxes together with three classmates and each of you is assigned to exactly one task (A-D).

We will not make lids for the boxes this time.

Then the stages to make a box should be (in this order)

A: Fold horizontially and vertically, unfold,

B: Fold four corners,

C: Fold sides to center,

D: Unfold two sides and reverse fold them to finish.

Assume the following amount of work in seconds is required at each station:

A: 28 secs, B: 33 secs, C: 45 secs, and D: 60 secs.

(Assume you want to make many boxes, i.e., perform the calculations for a continuous process.)

Additional Information:

Additionally, your brother/sister/friend wants to know what you are doing and is happy to join in.

1) What is the best way in which (s)he can help (assuming that (s)he can only help with one particular task)? Please answer in one short word or sentence.

2) With this additional helper, what is the new flow time (from plain paper to finished box)? Please give your answer in seconds.

3) What is the new bottleneck stage? What is the capacity rate of your process (boxes per hour)? Please round to 4 decimal places.

4) What is the capacity rate of your process (boxes per hour)? Please round to 4 decimal places. Additionally, what is the simple average of the utilization of your resources?
