MANE 6319 - Quality Management Systems
Student Learning Outcome 7 Assignment
Assignment Date: July 22, 2024
Due Date: July 31, 2024
Your assignment for Learning Objective 7 is to conduct a quality function deployment (QFD) assignment to construct a house of quality diagram. Your house of quality should contain items 1, 3, 4 and 5 found in Figure 17.1 on page 283 of your textbook. In steps 1 and 2 below, the italicized text contains additional instructions to help explain those steps.
Step 1. Select an Item
Select an inexpensive and common item found around your house or apartment. Your item could be something used within the house or kitchen, used outdoors in the yard or a sports item.
As an example, consider a garden (hand) shovel. Since I am using this item as an example, you may not use it for your assignment. Notice that it might be helpful to include a picture here.
Step 2. Select a Market Segment
Products are designed to meet the needs of their users. For this analysis, assume any market can be divided into commodity, hobbyist, or expert. Notice that the segment you select will have a strong influence on how you construct your house of quality.
Continuing the example, I will select the hobbyist market segment. The commodity market is aimed at the least skill segment that will only occasionally use your item. The hobbyist market segment will have a greater skill level and will use the item more frequently. The expert market segment will have the greatest skill level and will use the item most frequently and heavily. Someone in the commodity market segment would be interested in a garden shovel made of plastic. A person in the hobbyist market segment would appreciate a garden shovel made of steel with a wooden handle. Finally a person in the expert market segment would demand a high quality, durable product; so you would consider more exotic (and expensive) materials such as carbon fiber or titanium.
Step 3. Specify Customer Needs/Requirements
The customer needs are labelled item 1 in Figure 17.1 in your textbook. Your customer requirements must contain a minimum of two primary characteristics and a minimum of three secondary characteristics per primary characteristic. Tertiary characteristics are not required for this assignment. Figure 12-5 in the Learning Objective 7 handouts provides an example of customer requirements.
Step 4. Specify Technical Requirements
The technical requirements are labelled item 3 in Figure 17.1 in your textbook. The technical requirement must contain a minimum of two primary characteristics and each primary characteristic must contain at least three secondary requirements. It is recommended that you have a primary technical requirement regarding the material used in constructing your item and another primary technical requirement that address the manufacturing/assembly of you item. Figure 15-2 in the Learning Objective 7 handouts provides an example of technical requirements.
Step 5. Construct Interrelationships Matrix
The interrelationships matrix is labelled item 4 in Figure 17.1 in your textbook. The values for the interrelationships are typically 9 (high), 3 (medium), and 1 (weak). The values are highly dependent upon the needs of the customer identified in the market segment selection.
Step 6. Construct Correlation Matrix
The correlation matrix is labelled item 5 in Figure 17.1 in your textbook. The values of the correlation capture relationships between the technical requirements amongst themselves. Use the scoring scale found in Figure 12.9 in the Learning Objective 7 handouts.
Step 7. Construct House of Quality and Make Final Selection
Based upon the information gathered in steps 1 - 6, construct a house of quality for your selected item and market segment. Based upon the scoring in your house of quality, select a material and manufacturing process that will satisfy customers in your market segment. Include an explanation of your selection in Step 7.
