Consider, for example, a carpentry crew that is installing and taping drywall for
a total of 10,000 square feet (SF). The production rate for the crew is 500 SF per
day for installation and taping. The painting crew is directly behind, at a production
rate of 800 SF per day. Assume that the painting crew starts on day 2 (1 day after
the carpentry crew started); then, at the end of day 3, the carpentry crew would have
finished 500 3 = 1,500 SF, but the painting crew would have finished 800 2 =

⋅ ⋅

1,600 SF, which is impossible. There are four solutions for this problem.

1. Speed up the rate of the carpentry crew.
2. Slow the rate of the painting crew.
