Course Goals
1. To provide a fundamental understanding
of the PPAP evidence vital to producing
conforming product.
2. To ensure that all process, product, and
customer requirements are understood.
3. To ensure that the production processes
can meet all requirements.
PPAP Documentation Requirements
The focus of PPAP is Risk Reduction!
PPAP Process Requirements
PPAP Changes – 3rd to 4th Edition
• Align PPAP to ISO/TS 16949 process approach.
• Customer specific instructions moved to appropriate web
sites (OEM and IAOB, www.iatfglobaloversight.org).
• Truck OEM requirements moved to Appendix H.
• Parts Submission Warrant (PSW) revised.
• Material reporting and polymeric identification
requirements in the design record.
• Use of process capability indices (Cpk and Ppk).
Purpose of PPAP
• PPAP defines generic requirements for
production part approval.
• The purpose of PPAP is two-fold:
1. To determine if all customer engineering design
records and specification requirements are
properly understood.
2. To determine whether the manufacturing process
has the potential to produce product consistently
meeting these requirements at the quoted
production rate.
2.1 Significant Production Run
• For production parts, product for PPAP should be
taken from a significant production run.
• This significant production run shall consist of
from one hour to eight hours of production, and
with the specific production quantity to total a
minimum of 300 consecutive parts, unless
otherwise specified.
2.1 Significant Production Run
• This significant production run shall be:
– conducted at the production site,
– at specified production rates,
– using the production tooling,
– production gaging,
– production process,
– production materials,
– and production operators.
• Parts from each unique production process shall
be measured and tested.
4.1 Submission Levels
Level 1 Warrant and Appearance Approval Report (if designated appearance items
exist) submitted to the customer.
Level 2 Warrant with product samples and limited supporting data submitted to
the customer.
Level 3 Warrant with product samples and complete supporting data submitted to
the customer.
Level 4 Warrant and other requirements as defined by the customer.
Level 5 Warrant with product samples and complete supporting data reviewed at
the organization’s manufacturing facility.

PPAP Situations and Strategies
Exercise 1 – Question 1
400 consecutive parts are required in a significant
production run.
True
False
Exercise 1 – Question 4
You are to produce a high risk part or assembly, and
your customer authorized representative wanted to be
present for the significant production run. What level
PPAP would you expect to be specified?
Level 1
Level 2
Level 3
Level 4
Level 5
Exercise 1 – Question 5
If you were to produce a part, and your customer
wanted to specify exactly which elements of the PPAP
were to be submitted to, what level PPAP would you
expect to be specified?
Level 1
Level 2
Level 3
Level 4
Level 5
Exercise 1 – Question 6
Under what conditions would it be appropriate to
request an interim PPAP approval, rather than just
fixing existing deficiencies and applying for a full PPAP
approval?

The Genius of Dr. Hans J. Bajaria
Dr. Hans Bajaria synthesized
the work of the masters into
a practical, effective
structure to identify and
resolve problems.
Three Questions to be Taken in Order
Dr. Hans Bajaria claimed that these three questions
could identify three unique sets of causes.
1. Is the process stable?
2. Is there too much variation?
3. Is the process off-target?

The Genius of Dr. Walter A. Shewhart
Invented tools that
give us a rational
basis to know
whether data is
random or is affected
by assignable
causes.
Some Processes are Predictable
• Absence of Unexpected Changes
• Common Cause Variation
Time
• In Statistical Control
• Process is Stable

Process Potential
• Process Potential is simply the ratio between
the tolerance and the natural variation of the
process. Location of the distribution has no
impact on the figure of merit, Cp.

3. Is the process off-target?
Process Capability
• Process Capability is based on the number of
standard deviations between the worst case tail
of the curve and its corresponding specification
limit.

Cp and Cpk vs. Pp and Ppk
• Pp and Ppk are sometimes used to assess preliminary
process potential and capability.
• They are calculated using the same formulae as Cp and
Cpk.
• The difference is in how the standard deviation is
calculated.
