Exam 5: Managing Quality

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?

An automobile windshield manufacturer wants to verify that their process is producing windshields of an appropriate thickness.The best tool to determine this information is a(n):

Define employee empowerment and process ownership.How are these two concepts related?

Floyd Electric is fabricating flanges for a new electrical motor.The flange is to be 25 millimeters in diameter with an upper tolerance limit of 26.5 millimeters and a lower tolerance limit of 23.5 millimeters.Bill Floyd took a sample consisting of ten flanges,measured the diameter and recorded the observations in the table. What is Floyd Electric's process standard deviation?

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.Develop the proper statistical quality control charts.Is the process in control?

What are the seven core ideas of total quality management?

ISO 9001:2008 can be used by both manufacturing and service companies.

Garvin's dimension of durability is satisfied if the product fails infrequently.

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

Floyd Electric is fabricating flanges for a new electrical motor.The flange is to be 25 millimeters in diameter with an upper tolerance limit of 26.5 millimeters and a lower tolerance limit of 23.5 millimeters.Bill Floyd took a sample consisting of ten flanges,measured the diameter and recorded the observations in the table.He has heard discussion of 6 sigma in the business news recently and would like to join the club. What percentage decrease in process standard deviation would be required for Floyd Electric to achieve 6-sigma process capability? Assume that his process mean remains where it is.

Reductions in process variance result in higher process capability.

The probability of accepting a lot with worse quality than the lot tolerance percent defective level is ________.

Describe the four quality-related costs and tell how they are related.

Taguchi defines quality in terms of:

A housekeeping supervisor inspects rooms after the staff has cleaned them and compares their staff's performance against a checklist of items that should be cleaned,replaced,etc.,according to standard operating procedure at the hotel.Over the past week she finds three rooms that have cleaning mistakes out of the 140 rooms she has inspected.How many additional rooms should she sample to establish an average fraction defective for the p chart she would like to make to monitor this process?

________ is a family of standards,developed by the International Organization for Standardization,representing an international consensus on good quality management practices.

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?

Total Quality Management is the management of an entire organization so that it excels in all quality dimensions that are important to customers.
