Techniques to support ISO/TS 16949
Statistical Analysis Statistical Process Control (SPC) Measurement Systems Analysis (MSA) 15/11/61
49
Statistical 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 15/11/61
50
Statistical Analysis ISO/TS 16949:2002 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 Monitoring and measurement of manufacturing process Manufacturing process improvement 15/11/61
51
Statistical 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 15/11/61
52
Statistical 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 Non–random patterns or trends e.g. 7 points increasing/decreasing, 7 points one side of the average 15/11/61
53
Statistical 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 Cpk Approx parts per million out of specification 1.00 66,000 1.33 6,000 1.67 233 2.00 (Six sigma) 15/11/61
54
Statistical 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 15/11/61
55
Statistical 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) 15/11/61

Statistical Analysis Statistical Process Control (SPC) Measurement Systems Analysis (MSA) 15/11/61
57
Statistical 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. 15/11/61
58
Statistical Analysis - MSA
ISO/TS 16949:2002 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.” 15/11/61
59
Statistical 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. Material Man Method Machine (Time) Environment MEASUREMENT SYSTEM 15/11/61
60
Statistical 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. 15/11/61
61
Statistical 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. 15/11/61
62
Statistical 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 15/11/61
63
Statistical 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. To improve, appraiser(s) may need training, or more ease of use 15/11/61
64
Statistical 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. 15/11/61

Failure Modes & Effects Analysis 15/11/61
66
Failure Mode and Effects Analysis
Failure Mode and Effects Analysis (FMEA) A systematic group of activities to: Recognize and evaluate potential failures of a product or process and the effects of failure Identify actions that could eliminate or reduce the chance of the potential failure occurring Document the above process Evidence from vehicle recalls has shown a fully implemented FMEA could have prevented many causes Enables action before the event (Prevention), not after (Detection) 15/11/61
67
Failure Mode and Effects Analysis

68
Failure Mode and Effects Analysis
What are the customer related functions or requirements? How can cause or effect be prevented & detected? What should be done, by whom & when? design/ process change special controls, changes in procedures/ guides What are the effects? How bad is it? What can go wrong? No function Partial/over/ degraded function Intermittent function Unintended function How good is this method at detecting / preventing? What are the causes? What has been done? What risks are highest priority? Is there still a priority risk? How often does it happen? 15/11/61
69
Failure Mode and Effects Analysis
Design FMEA Focuses on designing out Potential Failures in Product Design causing detrimental effects on functional performance Applies when products’ design is created or revised Uses test, production, quality, supplier & customer experience Assumes manufacturing process would achieve specification Process FMEA Focuses on preventing Potential Failures in manufacturing Process causing detrimental effects 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 TEAM EFFORT TEAM EFFORT 15/11/61

Using the Risk Priority Number (RPN) …to prioritise action – focussing on preventing failure Customers may define triggers for action e.g. RPN >100, Severity > 8 RPN = Severity rating x Occurrence rating x Detection rating 15/11/61

Failure 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 15/11/61
73
Failure 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 15/11/61

Techniques to support ISO/TS 16949
Control Plans 15/11/61
75
Control Plans - Overview
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. 15/11/61
76
Control Plans - Requirement
ISO/TS 16949:2002 requirement for Control Plans [ ] “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…” 15/11/61
77
Control Plans - Content
ISO/TS 16949:2002 requirement for Control Plan content [ ] “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.” 15/11/61
78
Control Plans - Content
ISO/TS 16949:2002 requirement for Control Plan content [Annex A] General Data; part no. & name, process step descriptions, etc Product Control; characteristics for control; specif’n tolerance Process Control; process parameters, manuf’g m/cs & tools Methods; evaluation of meas’t technique, sample size & freq. Reaction Plan & corrective actions 15/11/61
79
Control Plans - Example
Control Plan Example format minimum elements required by ISO/TS 16949:2002 Annex A 15/11/61

Control 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? 15/11/61
81
Control 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) 15/11/61
