B) innovation and improvement of processes.
C) commitment to quality.
D) integration of suppliers and customers into the quality process.
E) use of quality tools

Answer 2

innovative marketing

Question 3

A flow chart is

A) a picture of the activities that take place in a process.
B) a tool used to test and implement changes in a process.
C) a statistical tool used to determine and control process variations.
D) used to indicate relationships between two variables or pairs of data.

Answer 3

a picture of the activities that take place in a process.

Question 4

Customers identify the key target set points for the products they require. The other process variables are identified in-house that support the ability of the process to produce the desired products; temperatures, flows, level, and pressure.

Question 5

A cause and effect diagram is

A) is a simple bar graph with classifications along the horizontal and vertical axis.
B) is used to indicate relationships between two variables or pairs of data.
C) is a method for summarizing available knowledge about the causes of process variation.
D) can vary from notes jotted down on a napkin to complex forms.

Question 6

Statistical process control is a quality tool, based upon the principles of statistical mathematics and applied to a process to control product quality.

Question 7

A cause and effect diagram is sometimes referred to as a

A) fishbone diagram.
B) herring bone diagram.
C) pareto.
D) run chart.

Question 8

What is a statistical tool used to determine and control process variations?

A) control chart
B) run chart
C) flow chart
D) pareto

Question 9

The planning phase of the improvement cycle should address all of the following except:

A) specific objectives and questions.
B) audit and evaluation.
C) predictions .
D) plan for test.

Question 10

Planned experimentation is

A) a tool used to test and implement changes to a process.
B) aimed at reducing variation.
C) used to understand the causes of variation (process problems).
D) all the above

Question 11

What quality tool can vary from notes jotted down on a napkin to complex forms?

A) run chart
B) control chart
C) forms for collecting data
D) pareto

Question 12

What is statistical control methodology applied to a process?

A) statistical process control (SPC)
B) run chart
C) flow chart
D) fishbone

Question 13

Quality tools include all of the following except:

A) statistical process control.
B) flowcharts.
C) cause and effect diagrams, fishbone.
D) pareto charts.
E) run charts.
F) control charts.
G) planned experimentation.
H) audit and evaluation.
I) histograms or frequency plots.
J) forms for collecting data.
K) scatter plots.

Question 14

The first step in the improvement cycle is to

A) increase current knowledge of the process.
B) identify the problem.
C) identify symptoms.
D) select possible solutions to problem.

Question 15

Histograms or frequency plots

A) are graphical tools used to understand variability.
B) are constructed with a block of data separated into five to twelve bars or sections from low number to high number.
C) have a vertical axis that is the frequency and the horizontal axis is the scale of characteristics.
D) are finished charts that resemble a bell if the data is in control.
E) all the above

Question 16

In today's global economy a new relationship exists between suppliers, companies and customers. Each is dependent upon the other for financial success.

Question 17

Phase two ________________ & ______________ implements the data collection process. The data collected will be used to address the questions from phase one.

A) observe and analyze
B) plan and learn
C) learn and act
D) none of the above

Question 18

A run chart is

A) used to indicate relationships between two variables or pairs of data.
B) a tool used to test and implement changes in a process.
C) a statistical tool used to determine and control process variations.
D) a graphical record of a process variable measured over time.

Question 19

The results from phase three are used to decide whether or not a change to the process is required. If a change is required a modified brainstorming session should be conducted to determine what changes to the process would result in improvement. These changes should be clearly stated.

Question 20

In any process a certain amount of variability can be found. Variability is defined as the tendency to vary. SPC identifies this variability and enhances an operators ability to control the process.

Question 21

A pareto chart is

A) used to indicate relationships between two variables or pairs of data.
B) a French quality system.
C) a herring bone diagram.
D) a simple bar graph with classifications along the horizontal and vertical axis.

Question 22

Before SPC operators would adjust their equipment based upon current readings. If the reading is taken when the processes normal variation is in a low cycle the operators adjustment will swing the process variable high. Adjustments made without SPC methodology tend to make the process swing high and low.

Question 23

SPC allows the normal fluctuations on the equipment to be considered over a longer period of time. Sample results must demonstrate a downward or upward trend above the key target set points.

Question 24

A histogram or frequency plots is a

A) graphical tool used to understand variability.
B) finished chart which will resemble a bell if the data is in control
C) a chart in which the vertical axis is the frequency and the horizontal axis is the scale of characteristics.
D) chart constructed with a block of data separated into five to twelve bars or sections from low number to high number.
E) all the above

Question 25

What quality tool is used to indicate relationships between two variables or pairs of data?

A) histogram
B) scatter plots
C) pareto
D) SPC chart
