When asking the question, what is the real problem, the project is very likely to be in the __________ stage.
Define
It is unlikely that earlier stages in the DMAIC process would be revisited as the project progresses.
False
Measurement Analysis is not necessary when monitoring the output of an automated process.
False
The "M" in the DMAIC cycle represents the management of the process.
False
The concept of measurement analysis is primarily related to the Analyze stage of the DMAIC Cycle.
False
The control phase comes before the Improve phase.
False
When Gage R&R results are precise, they will also be accurate.
False
he last step in the DMAIC process is to improve the situation.
False
A ____________ study focuses on whether the individuals collecting the data or performing measurement tests are consistent in their measurements.
Gage R&R
When several individuals measure the same object but each one records a different result this can be attributed to ____________________ .
Human Error
When taking a measurement of an object, if the device used to take the measurement incorrectly measures the object, this is referred to as a _____________ error
Measurement Device Error
Five human resource professionals rate a candidate on a scale of one to ten. The scores are almost the same, but it turns out that the individual, once hired, does not perform well and is not retained beyond the trial employment period. This is an example of _______________ .
Precise but not accurate
Consistency associated with a single individual in a Gage R&R study is addressed by the concept of _____________ .
Repetability
Which of the following terms suggests the approach where several people undertake the same test to rule out human error in measuring an object?

True
In a ____________ gage R&R study each individual operator only measures one part.
