MSSC Quality Practice&Measurement
can be very effective because it helps you unlock ideas that you would
have never thought of on your own. - Brainstorming
error comes from either built-in sources or calibration. - Instrument
inspections assure that the equipment, personnel and processes being
used are providing the desired results and allow problems to be pinpointed and
solutions implemented before the problems can escalate. - In-process
is data that can be gathered by answering one true-or-false question. -
Attribute data
may provide valuable information concerning a product's quality. -
Performing equipment checks during a quality inspection
measures the difference between an object's dimension and an object of
known length. - Indirect comparison
10 inches is the same length as mm. - 254
A avoids the errors of hand-held instruments by locating the parts in the
same place each time a measurement is made. - Fixture
A dimension is described in inches per foot. - Shaft taper
A has its graduations engraved so that they can not be rubbed off. -
Machinist's rule
A is a graphic method to show how the data is distributed across the range
of values. - Histogram
A is a measurement tool that measures part dimensions by indicating the
amount of distance its probe moves when placed against the part. - Dial Indicator
A is a plot of the data samples over time (a time-series plot). - Control
chart
A is a problem-solving method that organizes ideas generated from
brainstorming in small bite-size pieces which are arranged in a graphic manner. -
Fishbone (cause and effect) diagram
A is a theoretically perfect line, point or plane that is located by a similar
feature of the part. - Datum
A is the culmination of events resulting from an unscheduled line stoppage
or quality issue. - Corrective Action Report (CAR)

A is the total amount by which a specified dimension is allowed to vary and
still be a good part. - Tolerance
A is used to determine which type of defect most frequently occurs. -
Pareto chart
A is used to verify that the proper procedures and processes are being
adhered to by plant personnel. - Quality audit program
A should always be someone outside the organization. - Third party audit
group
A should be done as often as necessary to assure that the processes are
sound. - Quality system audit
A shows how one variable of a process varies with another variable. -
Scatter diagram
A 100% inspection of a new product revealed that a run of 200 parts resulted in several
parts being rejected. If the rejection rate was 3%. How many bad parts were created? -

is not critical to product function or performance. - Notify the supervisor to determine the
correct action to take
