4What is PPAP?
- Production Part Approval Process
- Standard used to formally reduce risks prior to
product or service release, in a team oriented
manner using well established tools and
techniques - Initially developed by AIAG (Auto Industry Action
Group) in 1993 with input from the Big 3 - Ford,
Chrysler, and GM - AIAGs 4th edition effective June 1, 2006 is the
most recent version - PPAP is part of the Donaldson Supplier Business
Operating Standard (S.B.O.S.S.)

61 Introduction
- it is the purpose of advanced quality management
to prevent that unreliable designs or processes
are used in serial production - therefore it is necessary to have one extensive,
strict approval process for new or changed
designs or processes - inevitably this process causes some
administration work - but its worth while because it reduces the
production of muda!
71 Introduction
Saving by taking advantage of the Rule Of The
10 The cost of the remedy of a defect
increases tenfold with every step, the project
advances!
81 Introduction
Savings by avoiding the 71 muda
91 Introduction
Savings by avoiding to high stock
- take space
- raise assets employed
- require additional searching
- require additional administration
- require additional transport
- are a risk, because parts might exceed expiration
date or become unsaleable - are a risk, because parts might be damaged
- complicate the overview
- are often a consequence of a weak process
- cover weak process
101 Introduction
Requirements for Lower stock
- ? Controlled and capable processes
- ? Total Productive Maintenance
- since all kind of process problems will cause
delivery stops, if the stocks are low!
111 Introduction
- satisfied customers by good quality and avoided
muda - no scrap, no rework
- constant flow of material
- low stocks possible
121 Introduction
- such an extensive and strict process is an
obligatory requirement - the name of this process is
- Production Part Approval Process

15PPAP is, so to speak, the goal of APD
- APD (APQP) makes sure
- that all requirements are recognized before the
Product Development is started - that those special characteristics of the
product are specified which influence these
requirements - that it is verified again and again that the
planned design can safely meet these
requirements, if the special characteristics are
within tolerance - that only those production processes are
specified, which are controlled and capable
according to SPC regarding these characteristics - A Readiness Review and PPAP are used to validate
that all processes are under control and capable - the produced parts fulfil all requirements
16Purpose and Applicability
- It is the purpose of PPAP to
- define generic requirements for production part
approval - determine if all customer engineering design
record and specification requirements are
properly understood by the organization - determine that the manufacturing process has the
potential to produce the product consistently
meeting these requirements during an actual
production run at the quoted production rate - Applicability
- PPAP shall apply to internal and external
organization sites supplying production
materials, sub assemblies or customer service
parts.For bulk material and standard catalogue
parts, PPAP is not required unless specified by
the APD project-team or customer. Material
certificates and dimensional reports are the
minimum required documents .
17Submission of PPAP
- Before any supply to the customer the
organization shall obtain full approval from the
customer for - Anny new serial part or serial product
- Correction of a discrepancy or any change on
previously submitted parts or part processes. - Product modified by an engineering change to
- design records
- specifications
- materials
- Any tool or equipment change or update.
- Note If there is any question concerning the
need for PPAP, contact the authorized customer
representative.

48Process FMEA (PFMEA) CORP QEHSDOC 014
- What is It?
- A tool used to identify and prioritize risk areas
and their mitigation plans.
- Objective or Purpose
- Identifies potential failure modes, causes, and
effects. Inputs come from the process flow
diagram. - Identifies key inputs which positively or
negatively affect quality, reliability and safety
of a product or process.
- When to Use It
- After completion of the process flow diagram.
- Prior to tooling for production
IMPORTANT!
The PFMEA should be completed using a
cross-functional team!
49FMEA Origin
- Created by NASA following Apollo 1 mission
failure - Allows us to take a proactive approach to what
can go wrong in a process and manage our risks
better
50Process FMEA (PFMEA)
51PFMEA - Step 1
- TIPS
- There should be at least one failure mode for
each input.
52PFMEA - Step 2
- TIPS
- There should be at least one failure effect for
each failure mode. - Effects should be specific, clear, and leave no
doubt to the uninformed reviewer.
53PFMEA - Step 3
- TIPS
- There should be at least one potential cause for
each failure mode.
54PFMEA - Step 4
- TIPS
- This step in the FMEA begins to identify initial
shortcomings or gaps in the current control plan.
- If a procedure exists, enter the document number.
- If no current control exists, list as none.
55PFMEA - Step 5
- Assign Severity, Occurrence, and Detection ratings
Severity, Occurrence and Detection rating details
on next slide
56PFMEA - Definition of Terms
- Severity (of Effect)Severity of the effect on
the Customer and other stakeholders (Higher Value
Higher Severity) - Occurrence (of Cause)Frequency with which a
given Cause occurs and creates Failure Mode.
(Higher Value Higher Probability of Occurrence) - Detection (Capability of Current Controls) -
ability of current Control scheme to detect the
cause before creating the failure mode and/or the
failure mode before suffering the effect (Higher
Value Lower Ability to Detect)
57An Example of Rating Definitions
Severity Occurrence Detection
Hazardous without warning Very high and almost inevitable Cannot detect or detection with very low probability
Loss of primary function High repeated failures Remote or low chance of detection
Loss of secondary function Moderate failures Low detection probability
Minor defect Occasional failures Moderate detection probability
No effect Failure unlikely Almost certain detection
Rating
High 10
Low 1
If No Controls Exist, Detection 10
Referring too 4th Edition FMEA Manual and the
scales in Donaldson PPAP workbook.
58PFMEA - Step 6
- TIPS
- The RPN is used to prioritize the most critical
risks identified in the first half of the FMEA. - High RPNs (100 or above) are flags to take effort
to reduce the calculated risk. - Regardless of RPN, high Severity scores (gt8)
should be given special attention.
59Analyzing the PFMEA
- Once the RPN Numbers are determined, they can be
used to prioritize the most significant failure
modes. - Sort the FMEA by the RPN numbers. Graphical and
statistical tools can help the team select a
cut-off RPN for the next steps.
- RPN Thresholds
- When using an RPN threshold, DO NOT forget to
address high Severity scores
Pareto Chart
60PFMEA Remediation Guidelines
- SeverityCan only be improved by a design change
to the product or process - OccurrenceCan only be reduced by a change which
removes or controls a cause. Examples are
redundancy, substituting a more reliable
component or function or mistake-proofing. - DetectionCan be reduced by improving detection.
Examples are mistake-proofing, simplification and
statistically sound monitoring.
61FMEA Step 7
- Determine Actions Recommended to reduce High RPNs
62FMEA Steps 8 and 9
- Now recalculate your RPNs
- based on mitigation plans.
- TIPS
- Continue updating the actions taken and
resulting RPNs until all risks are at an
acceptable level (below 100).
63Summary Steps To Complete a FMEA
- For each Process Input, determine the ways in
which the Process Step can go wrong (these are
Failure Modes). - For each Failure Mode associated with the inputs,
determine Effects on the outputs. - Identify potential Causes of each Failure Mode.
- List the Current Controls for each Cause.
- Assign Severity, Occurrence and Detection ratings
after creating a ratings key appropriate for your
project. - Calculate RPN.
- Determine Recommended Actions to reduce High
RPNs. - Take appropriate Actions and Document.
- Recalculate RPNs.
- Revisit steps 7 and 8 until all the significant
RPNs have been addressed.
64Tips and Lessons Learned
Process FMEA (PFMEA)
- Collaborative Effort Do not try alone, use a
group - Very comprehensive Time consuming process. Take
necessary breaks. - Action items are required for completion
- Train team ahead of time by explaining scoring
criteria - Proper preparation is needed for meetings
- Summarize often FMEA is a living document
65Process FMEA (PFMEA)
- Reviewers Checklist
- Verify there is a system for prioritizing risk of
failure such as RPN numbers of 150 or above - Make sure that high RPN process concerns are
carried over into the control plan - Make sure that all critical failure modes are
addressed - Safety
- Form, fit, function
- Material concerns

75Control Plan
Audit Plans
- Audit plans should be included in the control
plan as a separate line. - Auditing is an important tool for control.
- Process auditing should be a key element of the
quality system of a business. - Audits generally cover
- Effectiveness of controls
- Control plan (say) vs. what is actually done (do)
- Audits should be objective (done by internal or
external third parties if possible). - Audit frequencies should be based on balancing
level of risk (FMEA) and cost.
76Control Plan
Reviewers Checklist
- Use process flow diagram and PFMEA to build the
control plan keep them aligned - Controls must be used to be effective. Keep it
simple. - Ensure that the control plan is in the document
control system of the business. - Good control plans address
- All testing requirements - dimensional, material,
and performance - All product and process characteristics at every
step throughout the process - An periodical Audit. (Audit Frequency indicated
and data stamp for next Audit given!) - The control method should be based on an
effective analysis of the process - Such as SPC, Error Proofing, Inspection, Sampling
Plan - Control plans should reference other
documentation - Specifications, tooling, etc.

78Measurement System Analysis (MSA) Gage RR
79Attribute and Variable MSA
- Attribute Data Examples
- Count, Pass/fail, yes/no, red/green/yellow,
timekeeping buckets - Variable Data Examples
- Physical measurement (length, width, area, )
- Physical conditions (temperature, pressure)
- Physical properties (strength, load, strain)
- Continuous or non-ending
80Measurement System Analysis (MSA)
Measurement System Variation
The observed variation in process output
measurements is not simply the variation in the
process itself it is the variation in the
process plus the variation in measurement that
results from an inadequate measurement system.

enough to detect changes.
85Measurement System Analysis (MSA)
Repeatability
Error in RepeatabilityThe inability to get the
same answer from repeated measurements made of
the same item under absolutely identical
conditions. Possible Cause Lack of standard
operating procedures (SOP), lack of training,
measuring system variability.
Equipment Variation
86Measurement System Analysis (MSA)
Reproducibility
Error in ReproducibilityThe inability to get
the same answer from repeated measurements made
under various conditions from different
inspectors. Possible Cause Lack of SOP, lack of
training.
Appraiser Variation
87Variable MSA Gage RR Study
- Gage RR is the combined estimate of measurement
system Repeatability and Reproducibility - Typically, a 3-person study is performed
- Each person randomly measures 10 marked parts per
trial - Each person can perform up to 3 trials
- There are 3 key indicators
- EV or Equipment Variation
- AV or Appraiser Variation
- Overall GRR
88Donaldsons Gage RR Form
89Variable MSA Gage RR Steps
- Select 10 items that represent the full range of
long-term process variation. - Identify the appraisers.
- If appropriate, calibrate the gage or verify that
the last calibration date is valid. - Open the Gage RR worksheet in the PPAP book to
record data. - Have each appraiser assess each part 3 times
(trials first in order, second in reverse
order, third random). - Input data into the Gage RR worksheet.
- Enter the number of operators, trials, samples
and specification limits - Analyze data in the Gage RR worksheet.
- Assess MSA trust level.
- Take actions for improvement if necessary.
90Steps 1 and 2 Variable MSA - Gage RR
- Select 10 items that represent
- the full range of long-term process
- variation.
- Identify the appraisers.
- Should use individuals that actually do the
process being tested. - Can also include other appraisers (supervisors,
etc.). - Should have a minimum of 3 appraisers.
91Steps 3 and 4 Variable MSA Gage RR
- If appropriate, calibrate the gage
- or verify that the last calibration
- date is valid.
Open the Gage RR worksheet in the PPAP book to
record the data
92Step 5 Variable MSA Gage RR
- Have each appraiser assess each item 3 times.
- Each appraiser has to work independently.
- Items should be evaluated in random order.
- After each appraiser completes the first
evaluation of all items repeat the process at
least 2 more times. - Do not let the appraisers see any of the data
during the test !!
93Steps 6 and 7 Variable MSA Gage RR
- Input data into the Gage RR worksheet
Enter the number of operators, trials, samples
and specification limits
94Steps 8 and 9 Variable MSA Gage RR
- Analyze data in the Gage RR worksheet
- Assess MSA Trust Level.
- Red gt 30 (fail)
- Yellow 10-30 (marginal)
- Green lt 10 (pass)
95Step 10 Variable MSA Gage RR
- If the Measurement System needs improvement
- Brainstorm with the team for improvement
solutions. - Determine best practical solution (may require
some experimentation). - Pilot the best solution (PDSA)
- Implement best solution train employees.
- Re-run the study to verify the improvement.
96Variable MSA Gage RR Example
Problem Statement
- The sulfuric acid concentration in process tank 8
is measured at least once per day - Additions/deletions of chemicals and decisions to
shut down the process are dependent on these
results. - Based on current data, we need to do an MSA.
MSA Process
A Gage RR was conducted in order to validate
the process.
- MSA Parameters
- (3) Operators
- (3) Trials
- (10) Samples

Repeatability Reproducibility RR
99Tips and Lessons Learned
- Important An MSA is an analysis of the process,
not an analysis of the people. If an MSA fails,
the process failed. - A Variable MSA provides more analysis capability
than an Attribute MSA. For this and other
reasons, always use variable data if possible. - The involvement of people is the key to success.
- Involve the people that actually work the process
- Involve the supervision
- Involve the suppliers and customers of the
process - An MSA primarily addresses precision with limited
accuracy information.
100MSA Gage RR
Reviewers Checklist
- If the gage/inspection affects quality, then
conduct a Gage RR - Make sure the study is recent - less than 1 year
- Compare the control plan gages against the Gage
RRs - If you question that gage, then
- Question the technique and part sampling
- Ask for additional studies
