Non-Conformance Assessement & CAPA
7.1. Supplier training has become more widespread among U.S. companies . Which of
the following is the best reason for doing so?
a. To replace partnership relationships
b. To promote mutual trust between two suppliers c. To reduce costs and prevent future
problems
d. To share valuable proprietary information with key suppliers - ANS-Solution: Answer c
is a good selection . Answer d is an unethical or stupid choice (dependent upon
interpretation of the answer) . Training can augment a partnership not replace it (answer
a is wrong). There should be a customer and supplier relationship not supplier to
supplier trust (answer b is wrong) .
Answer c is correct.
Reference: CSQP Primer, Section VII- 45.
7.2. What is the upper control limit for a p chart (proportion defective) when the average
daily production
is 2,500 units with an established fraction defective of 0.05?
a. 0.054
b. 0.058
c. 0.063
d. 0.066 - ANS-Solution: This question requires an upper control limit calculation for the
p chart . Note that the question does not indicate that the sample size is fixed .
UCL = p + 3 (P)( - P)
Pn
(0.05)(1 - 0.05)
UCLP = 0.05 + 3 2500
UCLP = 0.05 + 0.013 = 0.063
,Answer c is correct.

& Leavenworth , R. S., Statistical Quality Control, page 225 . This question has been
modified from an old CQT handout.
7.3. A basic requirement of most gage calibration system specifications is:
a. All inspection equipment must be calibrated with master gage blocks
b. Gages must be color coded for identification
c. Equipment must be labeled to indicate date calibrated , by whom , and date for next
calibration
d. Gages must be identified with a tool number - ANS-Solution : Answers a, b, and d are
things you might want to consider when setting up a calibration system. However,
answer c is a basic requirement of gage calibration system specifications. Note that
some inspection equipment calibration does not use gage blocks.
Answer c is correct.
Reference: CSQP Primer, Section VII- 39/40.
7.4. The most significant elements of a material review report are the identification of
the type of defect and: a. The identification of the discrepant parts or materials
b. The identification of the operation in which the defect was introduced
c. A detailing of the quality history of the process
d. Identification of the responsible operator - ANS-Solution: The identification of the
discrepant parts or materials is essential. Answer a is correct. Answer d is false . Who
was responsible is traditionally a weak choice since the system is often to blame. The
history of the process may be useful information , but it is of fairly low importance .
Answer cis wrong. The operation in which the defect was introduced may not be known.
Answer b is incorrect.
Answer a is correct.
Reference: CSQP Primer , Section VII- 11.
7.5. Which of the following MRS actions would almost certainly require the involvement
of the customer ,
when a nonconforming product is discovered internally?
, a. Rework or repair of the product
b. Reject or scrap the product
c. Require additional inspection or testing
d. Initiate a corrective action request - ANS-Solution : Generally, the customer would not
be involved when a CAR is issued internally or when additional testing or inspection is
required (to make an informed decision). Thus , answers c and d are incorrect. The
customer is usually very involved in rework , repair and use "as is" decisions . Thus,
answer a is valid .
Usually, the customer is not involved in a scrap or reject decision, unless there are
extenuating circumstances (an equivalent item is involved, the product could be
salvaged in the customer's plant, but not in the supplier 's plant, etc) .
Answer a is correct.
Reference: CSQP Primer , Section VII- 10.
7.6. An experiment with two factors, in which all levels of one variable are run at each
level of the second variable, is called a:
a. One-way experiment
b. Latin square experiment
c. Full factorial experiment
d. Fractional factorial experiment - ANS-Solution : Depicted below are comparisons of
full and fractional factorial designs for three factors at two levels.
