2. Nonconformance Tracking
LHC Quality Assurance Working Group - M. Mottier September 2000
Objectives
To provide an on-line system to report,
analyze,and correct non conformities as
required by ISO 9001 and the LHC Quality
Assurance Plan:
To enable the reporting of non conformities, on-site
and off-site, detected in production, assembly and
installation.
To provide a comprehensive view of the state of
non conformities at part level, equipment level, and
project level.
To provide for searching, reporting and statistical
analysis.
3. Nonconformance Tracking
LHC Quality Assurance Working Group - M. Mottier September 2000
Method
Use the EDMS and its web interface.
Use a document, the nonconformance
report.
Use a specific document type, QN.
The nonconformance report (NCR) is used to
document the history from detection to
implementation of the solution.
The document status is used to display the main
steps in the nonconformance evolution

There is a problem
Waiting for a solution
There is a problem

5. Nonconformance Tracking
LHC Quality Assurance Working Group - M. Mottier September 2000
NC process step by step
Inspector (on production site)
Discovers a non-conformity.
Completes the IDENTIFICATION part of the NCR.
Stores the NCR in EDMS (status OPEN).
Production Manager (on production site)
Makes analyses and proposes a solution.
Updates NCR, point 13, possibly point 16.
Changes NCR status to UNDER APPROVAL.
Project Engineer/Project Management (at CERN)
Verifies and approves or rejects the proposed solution.
Decides whether management approval is required.
Finally changes status to ACCEPTED or REJECTED.
Production Manager (and PE if necessary)
Implements the solution.
Changes status to CLOSED when complete.
6. Nonconformance Tracking
LHC Quality Assurance Working Group - M. Mottier September 2000
Confidentiality
Inspector and Production Manager
May only see NC’s related to their contract
Project Engineer
May see NC’s related to all his contracts and to all
related equipment
Project Management
May see all NC’s related to the project
7. Nonconformance Tracking
LHC Quality Assurance Working Group - M. Mottier September 2000
Web interface
Specific form to store and search for
NC’s:
To clearly segregate NC’s, as processes, from
documents.
To display NC status and hide the NCR document
status.
To automatically assign the doc type.
Pre-defined search as for ECR’s
Search by status, like ECRs.
8. Nonconformance Tracking
LHC Quality Assurance Working Group - M. Mottier September 2000
Production sites without Internet (1)
Inspector:
Fills points 1 to 12 of the form and sends it to
Production Manager
Production Manager:
Fills point 13 of the form and faxes to PE at CERN
PE (or secretary)
Completes point 14 or 15 of the form and faxes it to
Production Manager
Creates an empty (no file attached) NC Report
Changes the status of NC to IN-PROGRESS
When Implementation is completed:
Scans the completed form and stores it in EDMS
Change status to CLOSED
9. Nonconformance Tracking
LHC Quality Assurance Working Group - M. Mottier September 2000
Production sites without Internet (2)
In cases where it has been demonstrated that
communication via the web is not possible:
Use the nonconformance report as a paper
document.
Communicate via telephone, fax and mail.
Scan and store the nonconformance report
when the nonconformance has been
resolved, with the status OBSOLETE.
