The procedure CEA-ESS-PJT-AQ-0004 (Procédure de traitement des non-
conformités et des demandes de modification du projet ESSI) covers non
conformity and change request.
It describes the process for the control of non conformities and for the
configuration baseline changes.

For the ESSI project, the reference configuration for an item is the

Most critical risks (9) - in severe zone - are currently :
- Management & Engineering : Unclear definition of interfaces K64
- CM assembly : Assembly contractor not fully efficient (at the starting time mainly) K64
- CM components : Series components integrated not matching performances K64
- CM components / Couplers : Pre-serie will not reach the expected performance during conditioning K128
- RFQ : Couplers not reaching specifications (800 kW) K64
- RFQ : Difficulties to perform RFQ sections brazing K64

CEA-F. Ardellier, Bilbao - 1st Brightness Workshop| 15th nov 2016 | PAGE 32KEY ELEMENTS FOR EFFICIENT INFORMATION
MANAGEMENT :
1. Perimeters (SoW) and Interfaces well identified and managed very accurately
2. Data to be registered have to be identified as « useful by users » (scientists and
/ or large infractructure organization) and could / will be provided by partners /
contributors.
3. Standards baseline and methodology have to be fixed in the reference
configuration and integrated in the Product Assurance Plan :
Requirements for partners
4. Communication, exchanges and decisions at the right level
1. Keep a collaborative spirit
5. Engineering tools must integrate « system approach »
1. Multi physics platform for design
2. Virtual reality for communication, interferences, maintenance plan …
3. Collaborative Platform for data exchanges
4. ERP, …
Engineering Soft Tools must be
customised to the needs and not drive
