The list of all quality control checks to perform;
Output tray, temporary allocated storage, etc
S2-PDGS-OLQC-020
The PDGS/OLQC function shall allow configuring and managing the different quality
control checks as a set of checklists, each one defining one or more checks to be applied
on a given product component or set of components.
S2-PDGS-OLQC-025
The PDGS/OLQC function shall be able to apply the checklists autonomously and
generate output reports under the form of quality-check PDIs.
S2-PDGS-OLQC-030
The PDGS/OLQC function shall systematically report the version of the checklist and a
reference to the inspected data as part of the resulting quality check PDIs.
S2-PDGS-OLQC-035
The quality-check PDIs generated by the PDGS/OLQC function shall systematically
include all checks performed, each one including an identification of the check and its
result.
S2-PDGS-OLQC-040
The PDGS/OLQC shall distinguish between different types of checks:
Sample checks aiming at sampling (probing) some specific items extracted from the
product data for off-line assessment via the MPA function.
Informative checks aiming at characterising/measuring the quality of the data;
Concluding checks aiming at summarising the quality of the data with a concluding
"pass" or "fail", and at generating operator alerts in real-time in case of a failed status.
The quality-check PDIs issued from informative or concluding checks will make part of the
user-product structure as On-Line Quality Check metadata defined as placeholder in the
[PDD].
The quality-check PDIs issued from sample checks will not be reported in the product
structure.
S2-PDGS-OLQC-045
The PDGS/OLQC function shall systematically consolidate a summary pass/fail status at
the term of each checklist processing stating whether all the configured concluding checks
have "passed" or whether at least one has "failed". The summary status shall be
systematically reported as part of the resulting quality-check PDI.
