Clinton 8 Manufacturing Flow - Continued Kitting –Triggered by Assembly and Inspection Data Sheet (work order) –Parts issued from inventory to kit Assembly –Performed by approved suppliers –May have selected suppliers perform electrical testing (TBD) –Assemblies –Completed assembly entered into inventory to close work order

9. GLAST LAT ProjectDOE/NASA Peer Critical Design Review, March 19-20, 2003 J. Clinton 9 Manufacturing Flow - Continued

10. GLAST LAT ProjectDOE/NASA Peer Critical Design Review, March 19-20, 2003 J. Clinton 10 Manufacturing Flow - Continued Circuit cards tested at SLAC –CCAs issued to test work order –CCAs are tested and returned to stores to close out the test work order End-item assembly parts are issued to assembly work orders and sent to assembly supplier(s) End items are received into project stores as they are received from the assembly supplier End items are issued to test work order for acceptance testing Upon completion of acceptance testing, end items are returned to project stores where are ready for issue to I&T

11. GLAST LAT ProjectDOE/NASA Peer Critical Design Review, March 19-20, 2003 J. Clinton 11 Non-Conforming Material Handling All non-conformances are documented on a Non-Conformance Report (NCR) –Identifies non-conforming item –Describes non-conformance –Describes environment unit was in at the time the non- conformance was discovered –Implemented using REMEDY Work stopped until NCR is reviewed and dispositioned by Material Review Board –Chaired by Quality Engineer –Supported by responsible engineer, manufacturing engineer, and other specialty engineers as appropriate –NCRs archived in a data base and kept with the item work order
