33. Should not be a meaningless listing of data.
Should review of all required components including:
Appropriate summary; evaluation and interpretation of the
information available on the manufacturing process.
Should have the capability of detecting long term trends.
Should not be considered in isolation and should be linked to
the findings of previous reviews.
34. Controlling and improving processes and quality
Highlighting areas for focusing resource thereby:-
◦ Decreasing risk of out-of specification results.
◦ Decreasing downtime and increasing productivity.
◦ Decreasing the risk of product recall.
◦ Enhancing regulatory compliance.
◦ Improving communication across all areas including production,
engineering, quality and regulatory functions.
35. Enhancement of visibility where manufacturing
operation are contracted out
(production, distribution, testing etc).
Improvement of product quality
Contributing to the protection of public and animal
health.
36. Trend data using appropriate statistical techniques
to draw the conclusions.
◦ Time series plots
◦ Control charts
◦ Process capability study
37. Facilitates corrective or preventive action should
the process be out of control.

(i) the process is in control; and
(ii) the process is capable.
38. Establishes control limits through trending
Determines the appropriateness of the specifications

42. An Xbar chart is used to observe and evaluate the behavior of a process over
time and take corrective action if necessary. The chart plots the average values of
each of a number of small sampled subgroups. It is usually plotted in conjunction
with the R (Range) Chart or the s (Standard Deviation) Chart
A. Sample Mean
B. Sample Number
C. Lower Control Limit (LCL)
D. Process Average
E. Upper Control Limit (UCL)
F. Plot of the individual sample
Means vs sample number.

B = Sample Number C=

D. Process Average

E. Upper Control Limit

F. Plot of the Range
values vs sample number.
The R Chart plots the range values, or the difference between the highest
and lowest values, for a series of subgroups.

B. Sample Number –
C. Lower Control Limit (LCL) –
D. Process Average –
E. Upper Control Limit (UCL)
F. Plot of the sample Standard
Deviation values vs sample
number.
The chart plots the standard deviation of each of a number of sampled
subgroups
45. Indices measure how well the data fits into the specification
limits.
Frequently used process capability indices include Cp and
Cpk.
Cp is used to evaluate the variation of the process.
Cpk is used to evaluate the centering of the process.
Normally the Cp / Cpk values be targeted at 1.33 or above
47. Cp and Cpk are statistical tools
Ensures that a production process has met the
specification limits defined for a particular process or
products.
Cp measures the process capability with respect to its
specification using Upper Specification Limit (USL)
and Lower Specification Limit (LSL)
48. Cpk measures the process variation with respect to its sample mean,
which is also considered to be the process mean.
Process capability is determined by taking periodic samples from
process under controlled conditions and calculating its standard
deviation and sample mean.
Standard deviation determines how far a sample is from the sample
mean
sample mean is the average of the samples taken under consideration.
49. Cp < 1: The process output
exceeds specifications. The
process is incapable.
Cp = 1: The process barely
meets specifications. There is a
probability that at least 0.3%
defects will be produced and
even more if the process is not
centered.
Cp > 1: The process output falls within specifications, but, defects might be
produced if the process is not centered on the target value.
Cp = 2: Represents the short-term objective for process capability. Since Zst = 3
x Cp, we achieve 6 sigma when Cp = 2.
50. Cpk = Cp: The process mean is
on target.
Cpk = 0: The process mean falls
on one of the specification limits,
therefore, 50% of the process
output falls beyond the
specification limits.
Cpk < -1: The process mean is completely out of the specification limits,
therefore, 100% of the process output is out of specification limits.
51. Other types of statistical techniques may also be
used
◦ Proper Interpretation of statistical analysis
◦ Conclusions to be drawn
◦ Determine whether the processes are in control and
capable.
◦ Initiate action if process are out of control

Complete corrective actions in a timely and effective
manner.
54. If M A holder is not the manufacturer, have a
technical agreement to define responsibilities
