Statistical
Process Control
You’ve
just been promoted to be the line supervisor for Ames Awesome Candies Company.
Immediately, you get a call that Finance noticed a cost variance in your
department. It appears that you are
consuming too few ingredients for your scheduled output. A box of Special Mixed Candies is supposed to
be 140 ounces, and your annual bonus is paid on how close you manage your
per/unit costs. To begin analyzing the
process, you ask your fill machine operator to record the weights of 9 candy
cartons each hour for the next 11 hours.

Project
Management
The
Northern Iowa Little Theater is planning its first play for the upcoming
season. However, due to illness of one
of their key board members, they are behind schedule. Their President, Dat Sarap, has used Project
Management principles to lay out the task relationships, and he finds they do
not have enough time to make the performance date if they follow the
traditional schedule as outlined below. Dat has come up with a list of tasks,
their time requirements, and their relationships. He has also begun a network diagram, but
needs to know what to do next. He knows that he needs to reduce the total time
by 4 weeks.
