"We conduct an internal Supplier Performance Review each quarter to track suppliers’ progress against a range of commercial and supply chain metrics in addition to performance against sustainability and social standards set out in the Supplier Manual and our Sustainability Policy. This review is conducted by the GM Procurement and the GM Technical. Following these reviews, suppliers are provided with a copy of their supplier assessment report which details their score out of 100 in addition to an action plan identifying areas and actions for improvement. Suppliers are rewarded for continual improvement, with suppliers who score less than 75 points losing their “approved supplier” status."

"In the coming year we will be proactively tracking non-conformances and close outs arising from these third party audits, and will create a metric to ensure continual improvement."
