Exam 5: Managing Quality

The ________ dimension of quality asks how long a product can go between failures or the need for maintenance.

A cell phone manufacturer inspects the video display on each color phone to verify that the screen can display all colors with the brilliance their customers have come to expect. Each phone is turned on, run through a self-test procedure, and classified as either acceptable or unacceptable based on test performance. The production team takes a sample of 350 phones and finds one with a defective display. How many additional phones should they sample to establish an average fraction defective for their statistical quality control initiative?

Taguchi's quality loss function is consistent with:

The ability of a non-centered process to meet certain tolerance limits is measured by its ________.

Joseph Juran's definition of quality as "fitness for use" is an example of the value perspective of quality.

________ are teams or individuals who have the authority and responsibility for improving the organization's business processes.

A barbecue sauce producer sells their product in a 20-ounce bottle. Their historical process mean has been 20 ounces with a standard deviation of 0.25 ounces. If their tolerance limits are set at 20 ounces plus or minus 1 ounce, what is the process capability ratio of the bottle filling process?

A technique used to translate customer requirements into technical requirements is:

Six Sigma quality means that the difference between the upper and lower tolerance levels is six standard deviations wide.

The probability of rejecting a lot with quality better than the acceptable quality level is:

Taguchi's ________ demonstrates that as soon as a quality characteristic deviates from the target value, there is a decline in the level of quality.

The fill size for a small bag of peanuts distributed by a popular airline is 50 grams. The producer wishes to set up a set of control charts for this process and collects the data shown in the table. What are the upper and lower control limits of their X-bar chart? Sample Item \#1 Item \#2 Item \#3 Item \#4 Sum 1 54.5 54.3 53.8 50.4 213.0 2 50.6 53.5 53.2 54.9 212.2 3 51.1 54.3 50.4 50.7 206.5 4 52.7 52.1 51.3 51.0 207.1 5 51.7 51.2 54.7 54.3 211.9 6 51.1 51.5 54.7 50.4 207.7 7 54.0 52.3 54.7 51.4 212.4 8 53.2 50.4 53.4 51.4 208.4 9 51.9 50.2 50.2 52.9 205.2

A person or company taking the stance that quality must be judged, in part, by how well the characteristics of a particular product or service align with the needs of a specific user is taking the ________ perspective.

Taguchi's quality loss function runs counter to the notion that a product falling within tolerance limits is acceptable.

A cell phone manufacturer inspects the video display on each color phone to verify that the screen can display all colors with the brilliance their customers have come to expect. Each phone is turned on, run through a self-test procedure, and classified as either acceptable or unacceptable based on test performance. The production team takes a sample of 350 phones and finds one with a defective display. How many additional phones should they sample to establish an average fraction defective for their statistical quality control initiative?

The fill size for a small bag of peanuts distributed by a popular airline is 50 grams. The producer wishes to set up a set of control charts for this process and collects the data shown in the table. What are the upper and lower control limits of their R-chart? Sample Item \#1 Item \#2 Item \#3 Item \#4 Sum 1 54.5 54.3 53.8 50.4 213.0 2 50.6 53.5 53.2 54.9 212.2 3 51.1 54.3 50.4 50.7 206.5 4 52.7 52.1 51.3 51.0 207.1 5 51.7 51.2 54.7 54.3 211.9 6 51.1 51.5 54.7 50.4 207.7 7 54.0 52.3 54.7 51.4 212.4 8 53.2 50.4 53.4 51.4 208.4 9 51.9 50.2 50.2 52.9 205.2

What is the difference between the traditional view of the cost of quality and the total cost of quality perspective?

An airline wants to monitor the performance of their baggage handling crew on the daily flight from Oklahoma City to Dallas that is always filled to its 140 passenger capacity. They track the number of passengers that lose bags each flight for a two-week period. The data are displayed in the following table. Determine control limits for the appropriate chart and indicate any points that are out of control. Day \# \# Bags Lost 1 3 2 4 3 3 4 2 5 5 6 7 7 6 8 8 9 1 10 7 11 6 12 2 13 1 14 7

The width between the upper and lower limits of a control chart should be wider than the width between the upper and lower tolerance limits.

In general, producer's risk rises as consumer's risk falls.
