QEM Solutions provided a highly qualified QA Engineer, with the required back-up support to assess the findings, and establish additional information, pertaining to possible valve failures on AEON supplied valves.
It is suspected that a number of “out of tolerance” stems have been supplied from a supplier based in China.
QEM Solutions reviewed all information available in order make an assumption on the number of affected valves and if possible identify the range of serial numbers affected.
QEM Solutions carried out an initial offsite Desk Based Assessment, to gain a full understanding of the valve anomaly. This was followed up with an onsite visit to the Alfreton office to validate additional information that cannot be established from the Desk based Assessment.
The Engineer reviewed all available information and issued a report detailing his conclusions on the following:
1. Appraising the current root cause analysis.
2. Identifying (if feasible) the number of valves affected
3. Identifying (if feasible) the potential serial range of affected valves.
This was achieved by carrying out the following activities:
a. Assessing reliability of existing data
b. Reviewing existing non-conformity reports
c. Reviewing existing QITP’s for both AEON and relevant suppliers
d. Reviewing Supplier control and procurement process
e. Reviewing subcontractor package and delivery process
