Every Halloween, the sisters of Alpha Delta Pi put together “Monster Bags” for children at the local hospital. Each Monster Bag consists of a paper bag stuffed with candy. Each bag has a character’s face drawn on it, with yarn hair and paper arms and legs attached.

For the past three years, several sisters have worked individually, putting together bags on their own. But because some of the women are much better artists than others, the quality of the Monster Bags has varied greatly.

Erika Borders, a supply chain major, has been thinking about this problem. She realizes that making each bag really consists of several steps:

A. Draw the face on the bag.

B. Cut out the arms and legs.

C. Attach the arms and legs.

D. Cut the yarn for the hair.

E. Attach the hair to the bag.
F. Fill the bag with candy.
G. Staple the bag closed.
Erika decides that the ideal solution would be to develop a little production line to make the bags. This way the most talented artists can focus on what they do best—drawing the characters’
faces. She has developed the time estimates and predecessor data for the tasks. Alpha Delta Pi needs to make 200 bags, and Erika feels she would have no problem getting volunteers to help if they could get all the bags done in four hours.
