Exception: If there is more than one evaluation for a question
In process elements P3, P4 (separate evaluation of product and process de-
velopment) and P6 (individual evaluation of each process step), there may be
several evaluations for a single question. In this case, the arithmetic mean of
all results for the question must be calculated first. In calculations following
this step, the average is rounded to two decimal places.
These averages replace the “points awarded” when calculating the level of
compliance of a process element.
For each question, the total number “possible points” is 10 – regardless of
the number of results per question.
Sub-elements of P6
In the process element P6, the following sub-elements are evaluated:
E
U1
Process input
E
U2
Work carried out
E
U3
Personnel resources
E
U4
Material resources
E
U5
Efficiency
E
U6
Process output
The evaluation of the sub-elements is carried out in the same manner as for
the process elements and the exceptional case: more than one evaluation for
a question.

Total points awarded for the relevant questions for the sub-
element of P6
Total possible points for the relevant questions
for this sub-element of P6
Individual process steps
The questions from P6 are used for the evaluation of the individual process
steps. All questions from P6 can be answered for each process step. The
compliance level E
n
of each process step can be calculated as follows:
E

[%] =
Total points awarded for the P6 questions for this process step

The overall compliance level E

Total points awarded for all evaluated questions from

, E
P4
,E
P5
,E
P6
and E
P7
Total possible points for these questions
For process elements P3 and P4, product development (E
P3
product) and
process development (E
P3
process) can be evaluated separately. To calculate
the overall result for all process elements (e.g. P2 to P7), the mean values of
the respective questions in section P3 and/or P4 are used. The downgrading
rules are applied to the entire process element P3 and/or P4 (joint evaluation
of product and process development).

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.
