48Techniques to support ISO/TS 16949
- Statistical Analysis
- Statistical Process Control (SPC)
- Measurement Systems Analysis (MSA)
49Statistical Analysis - SPC
- Statistical Process Control (SPC)
- The use of statistical techniques such as
control charts to analyse a process or its
outputs so as to take appropriate actions to
achieve and maintain a state of statistical
control and to improve process capability. - Detects variation in process measures to enable
- reduction of variation, and,
- prevention of defects / waste.
- Applied to all processes whose output measures
offer - Variable data e.g. part dimensions
- Attribute data conforming yes/no - that can be
counted e.g. parts received on-time
50Statistical Analysis
- ISO/TS 169492002 requirement for Statistical
Analysis - 8.0 Measurement, analysis and improvement
- 8.1.1 Identification of statistical tools
- 8.1.2 Knowledge of basic statistical concepts
- 8.2.3.1 Monitoring and measurement of
manufacturing process - 8.5.1.2 Manufacturing process improvement
51Statistical Analysis - SPC
- Variable data forms a pattern that, if stable,
can be described as a distribution.
Distributions, differ in - Location
- Spread
- Shape or any combination of these.
- If the shape of variable data is normal
(typical) - location is measured by the mean X
- spread is measured by the range R or standard
deviation sd - SPC can be applied to see if variation is
unacceptable
52Statistical Analysis - SPC
- Variation in variable data can come from
- Common causes natural random events which
affect all values of process output - Special causes intermittent, often
unpredictable causes making the process output
unstable - Control charts help identify special causes by
showing - Values beyond control limits
- Nonrandom patterns or trends e.g. 7 points
increasing/decreasing, 7 points one side of the
average
53Statistical Analysis - SPC
- Before assessing process capability, special
causes must be removed - Process Capability then measures
- How variable the process is Pp, Cp
- How process variation fits within the specified
limits Ppk, Cpk - how well it meets a customer
requirement
54Statistical Analysis - SPC
- Attribute data can be analysis using
- p chart for proportion of nonconforming parts
- u chart for nonconformities per unit
- np chart for the number of nonconforming parts
- c chart for the number of nonconformities
55Statistical Analysis SPC
- Benefits of Statistical Process Control (SPC)
- Show how successfully a process is adjusted
controlled to achieve consistent and therefore
predictable outputs e.g. conforming products - Flag any special causes of variation which need
to be identified and eliminated by local action - Quantify the effects of improvements in quality,
leading to reductions in waste (poor quality
costs)
56Techniques to support ISO/TS 16949
- Statistical Analysis
- Statistical Process Control (SPC)
- Measurement Systems Analysis (MSA)
57Statistical Analysis - MSA
- Why Measurement System Analysis?
- The purpose of any analysis of a measurement
system should be to better understand the sources
of variation that can influence the results
produced by the system. - To quantify and communicate the limitations of
specific measurement systems.
58Statistical Analysis - MSA
- ISO/TS 169492002 requirement for Measurement
Systems Analysis (MSA) 7.6.1 - Statistical studies shall be conducted to
analyse the variation present in the results of
each type of measuring and test equipment system.
This requirement shall apply to measurement
systems referenced in the control plan. The
analytical methods and acceptance criteria used
shall conform to those in customer reference
manuals on measurement systems analysis. Other
analytical methods of acceptance criteria may be
used if approved by the customer.
59Statistical Analysis - MSA
- Terminology
- Measurement system
- the collection of operations, procedures, gauges
and other equipment, software and personnel used
to assign a number to a characteristic being
measured the complete process used to obtain a
measurement.
60Statistical Analysis - MSA
- Terminology
- Gauge any device used to obtain measurements,
frequently used to refer specifically to the
devices used on the shop floor. - Calibration a set of operations that establish
under specific operating conditions, the
relationship between a measuring device and a
traceable standard of a known reference and
uncertainty. - Reference Value a reference for comparison,
normally determined under laboratory conditions
or using a more accurate instrument.
61Statistical Analysis - MSA
- Quality of measurement data
- If measurements are close to the reference value
the quality of the data is high - Measurement systems
- Must be in statistical control
- Must have small variability compared with
specified tolerance or manufacturing process
variability - Descrimination the amount of change from the
reference value that an instrument can detect and
faithfully indicate. - Typically the smallest graduation on the scale of
the instrument - Descrimination should be one tenth of the
tolerance range, however recently the
descrimination target is one tenth of the process
variation significantly less.
62Statistical Analysis - MSA
- Variability characterised by
- Location - bias, linearity, stability
- Width or spread repeatability, reproducibility
- Location Errors
- Bias the difference between the mean measurement
and the reference value. - Linearity the difference in bias through the
operating range - Stability the total variation in the
measurements obtained from a single
characteristic over time (change in bias over
time) - Check change in characteristic, such as values
from Electrical Test Equipment, between
calibration intervals - Plot data and take action if bias outside a
specified value
63Statistical Analysis - MSA
- Spread Errors (Gauge R R)
- Repeatability variation in measurements obtained
with one measurement instrument, when used
several times by one appraiser while measuring
the identical characteristic on the same part.
(Equipment Variation) - Under 10 considered acceptable
- To improve, instruments may need maintenance or
redesign - Reproducibility variation in measurements
obtained with one measurement instrument, when
used by different appraisers while measuring the
identical characteristic on the same part. - Under 10 considered acceptable
- To improve, appraiser(s) may need training, or
more ease of use
64Statistical Analysis - MSA
- Measurement System Study
- Select appraisers people already using the
instrument - Select measurement instrument has it the
required discrimination - Select parts from the process that represent
entire operating range e.g. several days
production and number each part. - Measurement System Analysis when?
- As processes change and improve, a measurement
system must be re-evaluated for its intended
purpose - For example, when there is a new product,
capability improvement, skill level change,
process change e.g. new equipment, change in work
environment, change in test method/procedure.
65Techniques to support ISO/TS 16949

on functional performance - Applies when manufacturing process is applied to
new product or changed - Uses test, design, quality, supplier customer
experience - Assumes if design made to spec., it would
otherwise succeed

70Failure Mode and Effects Analysis
- Design FMEA used to address potential risks in
the design achieving functional performance, by - Identifying potential design failures, their
causes effects - Rating the
- Severity of effects 1 to 10 (10 most severe),
- Occurrence of effects 1 to 10 (10 most
likely), - Detection/prevention of effects by current
controls eg. analysis, test 1 to 10 (10 not
likely to be detected/prevented), - using guidance available in DFMEA manuals.
- Using the Risk Priority Number (RPN)
- to prioritise action focussing on designing
out failure - Customers may define triggers for action e.g. RPN
gt100, Severity gt 8
RPN Severity rating x Occurrence rating x
Detection rating

72Failure Mode and Effects Analysis
- FMEA is successful as a process living
document, if - All links to external ( internal) customer
requirements from Design and Process elements are
understood and systematically reviewed for risk
of potential failure - Informed team approach leads to multidisciplinary
experience being shared to evaluate risk
consistently - Actions are planned at an early stage before
changes are considered too costly - Actions are taken as planned and the resulting
effect on the risk is evaluated and documented
73Failure Mode and Effects Analysis
- FMEA appears difficult, if
- Team does not have
- common understanding of the FMEA process
- agreement/guidance on ratings
- multidisciplinary experience particularly a
history of customer concerns or internal failures
to consider in evaluating a new item - time to work through sufficient detail and agree
actions - Relationship between Design and Process elements
and external ( internal) customer requirements
is not understood - Actions are not
- Planned early enough
- Followed through to achieve reward in better
satisfying customer
74Techniques to support ISO/TS 16949
75Control Plans - Overview
- Control Plans
- summarize the systems used to minimize process
and product variation, guiding manufacturing on
how to control the process and ensure product
quality - structure the approach to design, selection and
implementation of value-added control methods - describe the actions required at each phase of
the process to ensure all process outputs will be
in control - are living documents - updated as measurement
systems and control methods are evaluated and
improved.
76Control Plans - Requirement
- ISO/TS 169492002 requirement for Control Plans
7.5.1.1 - The organization shall
- develop control plans (see Annex A) for the
product supplied - have a control plan for pre-launch production
that takes into account the design FMEA and
manufacturing process FMEA outputs. - Control plans shall be reviewed and updated when
any change occurs - NOTE Customer approval may be required
77Control Plans - Content
- ISO/TS 169492002 requirement for Control Plan
content 7.5.1.1 - The control plan shall
- list the controls used for the manufacturing
process control, - include the methods for monitoring of control
exercised over special characteristics - include the customer required information, if
any, and, - initiate the specified reaction plan when the
process becomes unstable or not statistically
capable.
78Control Plans - Content
- ISO/TS 169492002 requirement for Control Plan
content Annex A - General Data part no. name, process step
descriptions, etc - Product Control characteristics for control
specifn tolerance - Process Control process parameters, manufg m/cs
tools - Methods evaluation of meast technique, sample
size freq. - Reaction Plan corrective actions
79Control Plans - Example
- Control Plan Example format
- minimum elements required by ISO/TS 169492002
Annex A
80Control Plans
- Control Plan Checklist
- Have customer requirements been adopted in
Control Plan format and preparation? - Have all known customer concerns been identified
to facilitate the selection of special
product/process characteristics? - Are all special product/process characteristics
included in the control plan? - Are material specifications requiring inspection
identified? - Does the control plan address incoming
material/components through processing/assembly
including packaging? - Are engineering performance testing requirements
identified - Are gauges and test equipment available as
required by the control plan? - If required, has the customer approved the
control plan? - Are gauge methods compatible between supplier
customer?
81Control Plans - Benefits
- Benefits of Control Plans
- Improved quality of products during design,
manufacturing and assembly, by identifying
sources of variation - Resources focussed on process and product
characteristics important for customer
satisfaction - Communication of
- changes in product/process characteristics and
their control measurement - prepared responses to nonconformities (Reaction
Plan)
