Charles Lackey operates a bakery in Idaho​ Falls, Idaho. Because of its excellent product and excellent​ location, demand has increased by 25​% in the last year. On far too many​ occasions, customers have not been able to purchase the bread of their choice. Because of the size of the​ store, no new ovens can be added.

George Kyparisis makes bowling balls in his Miami plant. With recent increases in his​ costs, he has a newfound interest in efficiency. George is interested in determining the productivity of his organization. He would like to know if his organization is maintaining the manufacturing average of a​ 3% increase in productivity.
