Process element P6: Production process analysis
How effectively is the process being carried out?
Effectiveness and efficiency
P6.5.1 Have targets been set for the production process?
Minimum requirements relevant for assessment
Examples for implementation
Process-specific targets are defined, monitored and
communicated.
Customer requirements are taken into account
when setting targets.
A regular comparison between specified targets
and actual results is made and documented.
• Key production figures, e.g.
quantities produced; quality
metrics, throughput times,
defect costs, process effec-
tiveness figures, plant and
machine availability)
• First time trough quality, First
pass yield
• Reduction of waste (e.g. re-
jects and rework, energy and
process materials)

P6.5.2 Is quality and process data collected in a way that allows for analysis?
Minimum requirements relevant for assessment
Examples for implementation
The quality and process parameters required to
demonstrate product conformity (target values) are
defined and documented. The actual data is rec-
orded and evaluated.
Special incidents are documented.
The recorded data can be allocated to a product
and process, the data is available, legible, accessi-
ble and archived as specified. Traceability require-
ments are met.
The collected data is analyzed, and appropriate im-
provement measures are initiated.
The potential for improvement must be continuously
determined based on findings relating to quality,
costs, and services.

P6.5.3* If product and process requirements are not met, are the causes
analyzed and the corrective actions checked for effectiveness?
Minimum requirements relevant for assessment
Examples for implementation
If product and process requirements are not met,
immediate actions are taken to fulfill the require-
ments, until it has been proven that the corrective
actions have been effective. The employees are fa-
miliar with these immediate corrective actions.
Suitable methods are implemented to analyze the
causes.
Repeat errors are recorded. A more detailed analy-
sis of the causes must be carried out accordingly.
Corrective actions are derived, their implementation
is monitored and the effectiveness verified,
The production control plan and the risk analysis
are updated as needed.
Non-conformities that affect the characteristics of
the delivered product are communicated to the cus-
tomer.
