Develop a fishbone diagram for the possible causes of your car not starting.

Problem 1: The Omega Shoe Company manufactures a number of different styles of athletic shoes. Its biggest seller is the X-Pacer running shoe. In 2008 Omega implemented a quality-management program. The company's shoe production for the past three years and manufacturing costs are as follows.

	Year
	2008	2009	2010
Units produced/input	32,000	34,600	35,500
Manufacturing cost	$278,000	291,000	305,000
Percent good quality	78%	83%	90%

Only one-quarter of the defective shoes can be reworked, at a cost of $2 apiece. Compute the manufacturing cost per good product for each of the three years and indicate the annual percentage increase or decrease resulting from the quality-management program.

Problem 2. 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 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.

a. Determine the weekly product yield of good-quality cabinets.

b. What would weekly product input have to be in order to achieve a final weekly product yield of 300 cabinets?

Answer 1

Solve the project management question by showing all the calculation part all along with concept and formulas used to solve it. The Colonial House Furniture Company makes four-drawer oak filing cabinets in six phases. In the first phase, the boards forming walls of the cabinet are cut; in the second phase, the front drawer panels are woodworked; in the third phase, the boards are sanded and completed; in the fourth phase, the boards are cleaned, stained and painted by a clear finish; in the fifth phase, the hardware for pulls, runners and fittings is installed; and in the final phase, the cabinets are assembled. Inspection takes place at each phase of the process and the average percentages of good-quality units are: 87%, 91%, 94%, 93%, 93% and 96%. The cabinets are made in weekly production runs with a product input for 300 units. Q1. Find the weekly product yield of good-quality cabinets. Q2.
