The Colonial House Furniture Company manufactures four-drawer oak filing cabinets in six stages. In the first stage, the boards forming the walls of the cabinet are cut; in the second stage, the front drawer panels are woodworked; in the third stage, the boards are sanded and finished; in the fourth stage, the boards are cleaned, stained, and painted with a clear finish; in the fifth stage, the hardware for pulls, runners, and fittings is installed; and in the final stage, the cabinets are assembled. Inspection occurs at each stage of the process, and the average percentages of good-quality units are as follows.

Stage.......Average Percentage of good quality

.......1..............87%

.......2..............91%

.......3..............94%

.......4..............93%

.......5..............93%

.......6..............96%

The cabinets are produced in weekly production runs with a product input for 300 units.
