Exam 18: Introduction to Quality and Statistical Process Control

In process improvement efforts,the goal is to first remove the common cause variation and then to reduce the special cause variation in a system.

A process flow chart is used to quantify a problem situation.

Which of the following is not among the most common sources of variation?

When discussing variation in the output of a process,which of the following is not true?

Which of the following is not true?

A company that fills soft drinks into bottles wishes to establish an -chart to monitor the average fill level in the bottles.To do this,the company has taken a series of samples of size n = 4 bottles.The overall average fill is 12.03 ounces.The average range for the subgroups has been .06 ounces.Based on this information,what is the upper limit of the 3-sigma control limit?

Because variations are unavoidable in a system,the output of the system is always unpredictable.

A trend chart would be useful for displaying the improvement that a company is making in the number of customer defects observed.

The cause-and-effect chart is an example of:

A p-chart would potentially be used to monitor the diameters of bolts made by a bolt manufacturing plant.

Hypothesis testing is considered to be one of the key basic seven tools of quality.

Brainstorming is used to generate ideas from employees but should not be used to gather ideas from managers.

Among Deming's 14 points are:

A manager who is interested in showing the relationship between the number of defects produced and the number of training hours provided to employees might try a scatter plot.

Which of the following is not a type of commonly used process control chart?

Which of the following would be most useful in generating ideas from a group of people that do not know one another and in which many people would be hesitant to speak up?

A profound implication to the Deming Cycle is:

We expect virtually all the data in a stable process to fall within 2 standard deviations of the mean.

Recently the manager of a printing department began tracking the number of reworked jobs done each day.A good method for displaying these data would be a fishbone diagram.

Which of the following quality leaders is considered responsible for applying the Pareto principle to quality improvement efforts?
