often this center brings together one or more lead functions in the organization. Purchasing, logistics, engineering and operations all play a role and closely coordinate with finance to realize the triple bottom-line (TBL) results needed for a successful supply chain sustainability initiative.

The SPO is also the ideal entity to facilitate both outbound and in-bound communications with suppliers and with executive stakeholders inside the organization.
