If during a specific audit, individual process elements from the overall ques-
tionnaire are evaluated, the result is calculated only on the basis of the evalu-
ated process elements. It must be specified in the audit report which process
elements have been used in the evaluation.
Example P5/P6/P7
If process elements P5, P6 and P7 are evaluated (e.g. auditing of series pro-
duction), the result is calculated as follows:
E
G(P5P6P7)
[%] =
Total points awarded for all evaluated questions from
P5, P6 and P7 (E
P5
,E
P6
and E
P7
)
Total possible points for these questions
Example P4
If only process element P4 is evaluated (e.g. audit at the time of handing the
project over to series production), the result is calculated as follows:
E
G(P4)
[%] =
Total points awarded for all evaluated questions from P4 (E
P4
)
Total possible points for these questions
The designations E
G(P5P6P7)
and E
G(P4)
are used to easily identify the process
elements evaluated.
Overall level of compliance
The overall result is rounded to the nearest percentage point.

Level of compliance for partial audits
To classify the level of compliance of a partial audit, the calculated level of
compliance (e.g. E
G(P5P6P7)
or E
G(P4)
) is compared to the benchmarks as given
above (at least 80% for a “B” classification of conditionally quality capable or
at least 90% for “A” quality capable).
Downgrading rules
Results from the process elements, sub-elements of P6 or process steps
have to be considered in the following downgrading rules and documented in
the audit report.
Reasons for downgrading from A to B even though the level of compli-
ance is E
G
or E
G(Pn)
≥ 90%
• At least one process element (P2 to P7) or process step (E
1
to E
n
) is
evaluated as having a level of compliance E
P
or E
n
< 80%
• A level of compliance E
U1
to E
U6
in one of the sub-elements of P6 is <
80%
• 4 points are awarded for at least one *-question
• 0 points are awarded for at least one question in the process audit
Reasons for downgrading to C even though the level of compliance is
E
G
or E
G(Pn)
≥ 80%
• At least one process element (P2 to P7) or process step (E
1
bis E
n
) is
evaluated as having a level of compliance E
P
oder E
n
< 70%.
• 0 points are awarded for at least one *-question
When applying the downgrading rules (process element, sub-element or pro-
cess steps), the individually calculated results E
Pn
, E
Un
and E
n
are rounded to
the nearest percentage point.
6.4 Evaluation of product groups
If required, the overall assessment of quality capability can be broken down
into product groups on the basis of individual process steps. Car manufactur-
ers mainly use this procedure to classify the suppliers’ quality capability. The
evaluation of the suppliers’ quality capability is thus restricted to product
groups. This forms part of the preconditions for future contract awards.

Note: To evaluate process steps, additional process requirements should be gener-
ated from the organization’s own knowledge databases.
In the evaluation matrix, the relevant process steps are allocated to the prod-
uct group being evaluated.
The overall level of compliance for each product group E
G(PGn)
is calculated as
follows:
E
G(PGn)
[%] =
Total points awarded for the questions for the evaluated
process elements Pn (for each question in P6, the average
value per question from the process steps for this PG is cal-
culated
++
)
Total possible points for the questions for the evaluated
process elements (
++
)

for explanations of “points awarded” and “possible points” see section: 6.2: Exception.
When evaluating product groups, the downgrading rules are applied specifi-
cally to the product group concerned.
