North Star Guns is a high technology enterprise making sophisticated products for the armaments market. One of the two profit centers, North Star Engineering, manufactures two types of electronic guidance units: “Standard” and “Deluxe.” These units require a high degree of skill in manufacturing. However, because of a shortage of trained engineers, North Star Engineering has only 100 skilled employees, whose total labor capacity (allowing for sickness, leaves, and so on) is expected to be 100,000 hours per year. The data for North Star Engineering follow.
