The spreadsheets on this page are being piloted by Sellafield's supply chain quality team. They clearly show the criteria Sellafield consider when assessing a supplier – working through them should give you a good idea of how you organisation shapes up.
These spreadsheets were supplied by Martin George, head of supply chain quality at Sellafield Ltd. Martin has kindly offered to answer any questions about the spreadsheets, so if anything is unclear you can email him or call him on 01946 785645 or 07739 301243.
